__call() public method

Defined in: yii\base\Component::__call()

Calls the named method which is not a class method.

This method will check if any attached behavior has the named method and will execute it if available.

Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.

public mixed __call ( $name, $params )
$name string

The method name

$params array

Method parameters

return mixed

The method return value

throws yii\base\UnknownMethodException

when calling unknown method

    foreach ($this->_behaviors as $object) {
        if ($object->hasMethod($name)) {
            return call_user_func_array([$object, $name], $params);
        }
    }
    throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()");
}

            
__clone() public method

Defined in: yii\base\Model::__clone()

This method is called after the object is created by cloning an existing one.

It removes all behaviors because they are attached to the old object.

public void __clone ( )

                public function __clone()
{
    parent::__clone();
    $this->_errors = null;
    $this->_validators = null;
}

            
__construct() public method

Defined in: yii\base\BaseObject::__construct()

Constructor.

The default implementation does two things:

  • Initializes the object with the given configuration $config.
  • Call init().

If this method is overridden in a child class, it is recommended that

  • the last parameter of the constructor is a configuration array, like $config here.
  • call the parent implementation at the end of the constructor.
public void __construct ( $config = [] )
$config array

Name-value pairs that will be used to initialize the object properties

                public function __construct($config = [])
{
    if (!empty($config)) {
        Yii::configure($this, $config);
    }
    $this->init();
}

            
__get() public method

Defined in: yii\db\BaseActiveRecord::__get()

PHP getter magic method.

This method is overridden so that attributes and related objects can be accessed like properties.

See also getAttribute().

public mixed __get ( $name )
$name string

Property name

return mixed

Property value

throws yii\base\InvalidArgumentException

if relation name is wrong

                public function __get($name)

        return null;
    }
    if (isset($this->_related[$name]) || array_key_exists($name, $this->_related)) {
        return $this->_related[$name];
    }
    $value = parent::__get($name);
    if ($value instanceof ActiveQueryInterface) {
        $this->setRelationDependencies($name, $value);
        return $this->_related[$name] = $value->findFor($name, $this);
    }
    return $value;
}

            
__isset() public method

Defined in: yii\db\BaseActiveRecord::__isset()

Checks if a property value is null.

This method overrides the parent implementation by checking if the named attribute is null or not.

public boolean __isset ( $name )
$name string

The property name or the event name

return boolean

Whether the property value is null

                public function __isset($name)

public void afterSave ( $insert, $changedAttributes )
$insert boolean

Whether this method called while inserting a record. If false, it means the method is called while updating a record.

$changedAttributes array

The old values of attributes that had changed and were saved. You can use this parameter to take action based on the changes made for example send an email when the password had changed or implement audit trail that tracks all the changes. $changedAttributes gives you the old attribute values while the active record ($this) has already the new, updated values.

Note that no automatic type conversion performed by default. You may use yii\behaviors\AttributeTypecastBehavior to facilitate attribute typecasting. See https://www.yiiframework.com/doc-2.0/guide-db-active-record.html#attributes-typecasting.

}

            
attachBehaviors() public method

Defined in: yii\base\Component::attachBehaviors()

Attaches a list of behaviors to the component.

Each behavior is indexed by its name and should be a yii\base\Behavior object, a string specifying the behavior class, or an configuration array for creating the behavior.

See also attachBehavior().

public void attachBehaviors ( $behaviors )
$behaviors array

List of behaviors to be attached to the component

                public function attachBehaviors($behaviors)
{
    $this->ensureBehaviors();
    foreach ($behaviors as $name => $behavior) {
        $this->attachBehaviorInternal($name, $behavior);
    }
}

            
attributeHints() public method (available since version 2.0.4)

Defined in: yii\base\Model::attributeHints()

Returns the attribute hints.

Attribute hints are mainly used for display purpose. For example, given an attribute isPublic, we can declare a hint Whether the post should be visible for not logged in users, which provides user-friendly description of the attribute meaning and can be displayed to end users.

Unlike label hint will not be generated, if its explicit declaration is omitted.

Note, in order to inherit hints defined in the parent class, a child class needs to merge the parent hints with child hints using functions such as array_merge().

public array attributeHints ( )
return array

Attribute hints (name => hint)

                public function attributeHints()
{
    return [];
}

            
attributeLabels() public method

Returns the attribute labels.

Attribute labels are mainly used for display purpose. For example, given an attribute firstName, we can declare a label First Name which is more user-friendly and can be displayed to end users.

By default an attribute label is generated using generateAttributeLabel(). This method allows you to explicitly specify attribute labels.

Note, in order to inherit labels defined in the parent class, a child class needs to merge the parent labels with child labels using functions such as array_merge().

public array attributeLabels ( )
return array

Attribute labels (name => label)

                public function attributeLabels()
{
    return [
        'module_name' => Module::t('model_navitemmodule_module_name_label'),
        'controller_name' => 'Controller Name',
        'action_name' => 'Action Name',
        'action_params' => 'Action Params',
    ];
}

            
attributes() public method

Defined in: yii\db\ActiveRecord::attributes()

Returns the list of all attribute names of the model.

The default implementation will return all column names of the table associated with this AR class.

public array attributes ( )
return array

List of attribute names.

                public function attributes()
{
    return static::getTableSchema()->getColumnNames();
}

            
beforeDelete() public method

Defined in: yii\db\BaseActiveRecord::beforeDelete()

This method is invoked before deleting a record.

The default implementation raises the EVENT_BEFORE_DELETE event. When overriding this method, make sure you call the parent implementation like the following:

public function beforeDelete()
{
    if (!parent::beforeDelete()) {
        return false;
    }

    // ...custom code here...
    return true;
}
public boolean beforeDelete ( )
return boolean

Whether the record should be deleted. Defaults to true.

                public function beforeDelete()
{
    $event = new ModelEvent();
    $this->trigger(self::EVENT_BEFORE_DELETE, $event);
    return $event->isValid;
}

            
beforeSave() public method

Defined in: yii\db\BaseActiveRecord::beforeSave()

This method is called at the beginning of inserting or updating a record.

The default implementation will trigger an EVENT_BEFORE_INSERT event when $insert is true, or an EVENT_BEFORE_UPDATE event if $insert is false. When overriding this method, make sure you call the parent implementation like the following:

public function beforeSave($insert)
{
    if (!parent::beforeSave($insert)) {
        return false;
    }

    // ...custom code here...
    return true;
}
public boolean beforeSave ( $insert )
$insert boolean

Whether this method called while inserting a record. If false, it means the method is called while updating a record.

return boolean

Whether the insertion or updating should continue. If false, the insertion or updating will be cancelled.

                public function beforeSave($insert)
{
    $event = new ModelEvent();
    $this->trigger($insert ? self::EVENT_BEFORE_INSERT : self::EVENT_BEFORE_UPDATE, $event);
    return $event->isValid;
}

            
beforeValidate() public method

Defined in: yii\base\Model::beforeValidate()

This method is invoked before validation starts.

The default implementation raises a beforeValidate event. You may override this method to do preliminary checks before validation. Make sure the parent implementation is invoked so that the event can be raised.

public boolean beforeValidate ( )
return boolean

Whether the validation should be executed. Defaults to true. If false is returned, the validation will stop and the model is considered invalid.

                public function beforeValidate()
{
    $event = new ModelEvent();
    $this->trigger(self::EVENT_BEFORE_VALIDATE, $event);
    return $event->isValid;
}

            
behaviors() public method

Defined in: yii\base\Component::behaviors()

Returns a list of behaviors that this component should behave as.

Child classes may override this method to specify the behaviors they want to behave as.

The return value of this method should be an array of behavior objects or configurations indexed by behavior names. A behavior configuration can be either a string specifying the behavior class or an array of the following structure:

'behaviorName' => [
    'class' => 'BehaviorClass',
    'property1' => 'value1',
    'property2' => 'value2',
]

Note that a behavior class must extend from yii\base\Behavior. Behaviors can be attached using a name or anonymously. When a name is used as the array key, using this name, the behavior can later be retrieved using getBehavior() or be detached using detachBehavior(). Anonymous behaviors can not be retrieved or detached.

Behaviors declared in this method will be attached to the component automatically (on demand).

public array behaviors ( )
return array

The behavior configurations.

                public function behaviors()
{
    return [];
}

            
canGetProperty() public method

        return true;
    }
    try {
        return $this->hasAttribute($name);
    } catch (\Exception $e) {
        // `hasAttribute()` may fail on base/abstract classes in case automatic attribute list fetching used
        return false;
    }
}

            
canSetProperty() public method

Defined in: yii\db\BaseActiveRecord::canSetProperty()

Returns a value indicating whether a property can be set.

A property can be written if:

  • the class has a setter method associated with the specified name (in this case, property name is case-insensitive);
  • the class has a member variable with the specified name (when $checkVars is true);
  • an attached behavior has a writable property of the given name (when $checkBehaviors is true).
public boolean canSetProperty ( $name, $checkVars true, $checkBehaviors true )
$name string

The property name

$checkVars boolean

Whether to treat member variables as properties

$checkBehaviors boolean

Whether to treat behaviors' properties as properties of this component

    if (parent::canSetProperty($name, $checkVars, $checkBehaviors)) {
        return true;
    }
    try {
        return $this->hasAttribute($name);
    } catch (\Exception $e) {
        // `hasAttribute()` may fail on base/abstract classes in case automatic attribute list fetching used
        return false;
    }
}

            
className() public static method

Defined in: yii\base\BaseObject::className()

Returns the fully qualified name of this class.

public static string className ( )
return string

The fully qualified name of this class.

                public static function className()
{
    return get_called_class();
}

                public function clearErrors($attribute = null)
{
    if ($attribute === null) {
        $this->_errors = [];
    } else {
        unset($this->_errors[$attribute]);
    }
}

            
createRelationQuery() protected method (available since version 2.0.12)

    $query = $class::find();
    $query->primaryModel = $this;
    $query->link = $link;
    $query->multiple = $multiple;
    return $query;
}

            
createValidators() public method

Creates validator objects based on the validation rules specified in rules().

Unlike getValidators(), each time this method is called, a new list of validators will be returned.

public ArrayObject createValidators ( )
return ArrayObject

Validators

throws yii\base\InvalidConfigException

if any validation rule configuration is invalid

                public function createValidators()
{
    $validators = new ArrayObject();
    foreach ($this->rules() as $rule) {
        if ($rule instanceof Validator) {
            $validators->append($rule);
        } elseif (is_array($rule) && isset($rule[0], $rule[1])) { // attributes, validator type
            $validator = Validator::createValidator($rule[1], $this, (array) $rule[0], array_slice($rule, 2));
            $validators->append($validator);
        } else {
            throw new InvalidConfigException('Invalid validation rule: a rule must specify both attribute names and validator type.');
        }
    }
    return $validators;
}

            
delete() public method

Defined in: yii\db\ActiveRecord::delete()

Deletes the table row corresponding to this active record.

This method performs the following steps in order:

  1. call beforeDelete(). If the method returns false, it will skip the rest of the steps;
  2. delete the record from the database;
  3. call afterDelete().

In the above step 1 and 3, events named EVENT_BEFORE_DELETE and EVENT_AFTER_DELETE will be raised by the corresponding methods.

public integer|false delete ( )
return integer|false

The number of rows deleted, or false if the deletion is unsuccessful for some reason. Note that it is possible the number of rows deleted is 0, even though the deletion execution is successful.

throws yii\db\StaleObjectException

if optimistic locking is enabled and the data being deleted is outdated.

throws Throwable

in case delete failed.

                public function delete()
{
    if (!$this->isTransactional(self::OP_DELETE)) {
        return $this->deleteInternal();
    }
    $transaction = static::getDb()->beginTransaction();
    try {
        $result = $this->deleteInternal();
        if ($result === false) {
            $transaction->rollBack();
        } else {
            $transaction->commit();
        }
        return $result;
    } catch (\Exception $e) {
        $transaction->rollBack();
        throw $e;
    } catch (\Throwable $e) {
        $transaction->rollBack();
        throw $e;
    }
}

            
deleteAll() public static method

Defined in: yii\db\ActiveRecord::deleteAll()

Deletes rows in the table using the provided conditions.

For example, to delete all customers whose status is 3:

Customer::deleteAll('status = 3');

Warning: If you do not specify any condition, this method will delete all rows in the table.

Note that this method will not trigger any events. If you need EVENT_BEFORE_DELETE or EVENT_AFTER_DELETE to be triggered, you need to find the models first and then call delete() on each of them. For example an equivalent of the example above would be:

$models = Customer::find()->where('status = 3')->all();
foreach ($models as $model) {
    $model->delete();
}

For a large set of models you might consider using yii\db\ActiveQuery::each() to keep memory usage within limits.

public static integer deleteAll ( $condition null, $params = [] )
$condition string|array|null

The conditions that will be put in the WHERE part of the DELETE SQL. Please refer to yii\db\Query::where() on how to specify this parameter.

$params array

The parameters (name => value) to be bound to the query.

return integer

The number of rows deleted

                public static function deleteAll($condition = null, $params = [])
{
    $command = static::getDb()->createCommand();
    $command->delete(static::tableName(), $condition, $params);
    return $command->execute();
}

            
deleteInternal() protected method

Defined in: yii\db\ActiveRecord::deleteInternal()

Deletes an ActiveRecord without considering transaction.

protected integer|false deleteInternal ( )
return integer|false

The number of rows deleted, or false if the deletion is unsuccessful for some reason. Note that it is possible the number of rows deleted is 0, even though the deletion execution is successful.

throws yii\db\StaleObjectException

                protected function deleteInternal()
{
    if (!$this->beforeDelete()) {
        return false;
    }
    // we do not check the return value of deleteAll() because it's possible
    // the record is already deleted in the database and thus the method will return 0
    $condition = $this->getOldPrimaryKey(true);
    $lock = $this->optimisticLock();
    if ($lock !== null) {
        $condition[$lock] = $this->$lock;
    }
    $result = static::deleteAll($condition);
    if ($lock !== null && !$result) {
        throw new StaleObjectException('The object being deleted is outdated.');
    }
    $this->setOldAttributes(null);
    $this->afterDelete();
    return $result;
}

            
detachBehavior() public method

Defined in: yii\base\Component::detachBehavior()

Detaches a behavior from the component.

The behavior's yii\base\Behavior::detach() method will be invoked.

public yii\base\Behavior|null detachBehavior ( $name )
$name string

return yii\base\Behavior|null

The detached behavior. Null if the behavior does not exist.

                public function detachBehavior($name)
{
    $this->ensureBehaviors();
    if (isset($this->_behaviors[$name])) {
        $behavior = $this->_behaviors[$name];
        unset($this->_behaviors[$name]);
        $behavior->detach();
        return $behavior;
    }
    return null;
}

            
detachBehaviors() public method

Defined in: yii\base\Component::detachBehaviors()

Detaches all behaviors from the component.

public void detachBehaviors ( )

                public function detachBehaviors()
{
    $this->ensureBehaviors();
    foreach ($this->_behaviors as $name => $behavior) {
        $this->detachBehavior($name);
    }
}

            
ensureBehaviors() public method

Defined in: yii\base\Component::ensureBehaviors()

Makes sure that the behaviors declared in behaviors() are attached to this component.

public void ensureBehaviors ( )

                public function ensureBehaviors()

        $this->_behaviors = [];
        foreach ($this->behaviors() as $name => $behavior) {
            $this->attachBehaviorInternal($name, $behavior);
        }
    }
}

            
equals() public method

Defined in: yii\db\ActiveRecord::equals()

Returns a value indicating whether the given active record is the same as the current one.

The comparison is made by comparing the table names and the primary key values of the two active records. If one of the records is new they are also considered not equal.

public boolean equals ( $record )
$record yii\db\ActiveRecord

Record to compare to

return boolean

Whether the two active records refer to the same row in the same database table.

                public function equals($record)
{
    if ($this->isNewRecord || $record->isNewRecord) {
        return false;
    }
    return static::tableName() === $record->tableName() && $this->getPrimaryKey() === $record->getPrimaryKey();
}

            
extraFields() public method

Defined in: yii\base\ArrayableTrait::extraFields()

Returns the list of fields that can be expanded further and returned by toArray().

This method is similar to fields() except that the list of fields returned by this method are not returned by default by toArray(). Only when field names to be expanded are explicitly specified when calling toArray(), will their values be exported.

The default implementation returns an empty array.

You may override this method to return a list of expandable fields based on some context information (e.g. the current application user).

See also:

public array extraFields ( )
return array

The list of expandable field names or field definitions. Please refer to fields() on the format of the return value.

                public function extraFields()
{
    return [];
}

            
extractFieldsFor() protected method (available since version 2.0.14)

Defined in: yii\base\ArrayableTrait::extractFieldsFor()

Extract nested fields from a fields collection for a given root field Nested fields are separated with dots (.). e.g: "item.id" The previous example would extract "id".

protected array extractFieldsFor ( array $fields, $rootField )
$fields array

The fields requested for extraction

$rootField string

The root field for which we want to extract the nested fields

return array

Nested fields extracted for the given field

                protected function extractFieldsFor(array $fields, $rootField)
{
    $result = [];
    foreach ($fields as $field) {
        if (0 === strpos($field, "{$rootField}.")) {
            $result[] = preg_replace('/^' . preg_quote($rootField, '/') . '\./i', '', $field);
        }
    }
    return array_unique($result);
}

            
extractRootFields() protected method (available since version 2.0.14)

Defined in: yii\base\ArrayableTrait::extractRootFields()

Extracts the root field names from nested fields.

Nested fields are separated with dots (.). e.g: "item.id" The previous example would extract "item".

protected array extractRootFields ( array $fields )
$fields array

The fields requested for extraction

return array

Root fields extracted from the given nested fields

                protected function extractRootFields(array $fields)
{
    $result = [];
    foreach ($fields as $field) {
        $result[] = current(explode('.', $field, 2));
    }
    if (in_array('*', $result, true)) {
        $result = [];
    }
    return array_unique($result);
}

            
fields() public method

Defined in: yii\base\ArrayableTrait::fields()

Returns the list of fields that should be returned by default by toArray() when no specific fields are specified.

A field is a named element in the returned array by toArray().

This method should return an array of field names or field definitions. If the former, the field name will be treated as an object property name whose value will be used as the field value. If the latter, the array key should be the field name while the array value should be the corresponding field definition which can be either an object property name or a PHP callable returning the corresponding field value. The signature of the callable should be:

function ($model, $field) {
    // return field value
}

For example, the following code declares four fields:

  • email: the field name is the same as the property name email;
  • firstName and lastName: the field names are firstName and lastName, and their values are obtained from the first_name and last_name properties;
  • fullName: the field name is fullName. Its value is obtained by concatenating first_name and last_name.
return [
    'email',
    'firstName' => 'first_name',
    'lastName' => 'last_name',
    'fullName' => function () {
        return $this->first_name . ' ' . $this->last_name;
    },
];

In this method, you may also want to return different lists of fields based on some context information. For example, depending on the privilege of the current application user, you may return different sets of visible fields or filter out some fields.

The default implementation of this method returns the public object member variables indexed by themselves.

See also toArray().

public array fields ( )
return array

The list of field names or field definitions.

                public function fields()
{
    $fields = array_keys(Yii::getObjectVars($this));
    return array_combine($fields, $fields);
}

            
find() public static method

Defined in: yii\db\ActiveRecord::find()

Creates an yii\db\ActiveQueryInterface instance for query purpose.

The returned yii\db\ActiveQueryInterface instance can be further customized by calling methods defined in yii\db\ActiveQueryInterface before one() or all() is called to return populated ActiveRecord instances. For example,

// find the customer whose ID is 1
$customer = Customer::find()->where(['id' => 1])->one();

// find all active customers and order them by their age:
$customers = Customer::find()
    ->where(['status' => 1])
    ->orderBy('age')
    ->all();

This method is also called by yii\db\BaseActiveRecord::hasOne() and yii\db\BaseActiveRecord::hasMany() to create a relational query.

You may override this method to return a customized query. For example,

class Customer extends ActiveRecord
{
    public static function find()
    {
        // use CustomerQuery instead of the default ActiveQuery
        return new CustomerQuery(get_called_class());
    }
}

The following code shows how to apply a default condition for all queries:

class Customer extends ActiveRecord
{
    public static function find()
    {
        return parent::find()->where(['deleted' => false]);
    }
}

// Use andWhere()/orWhere() to apply the default condition
// SELECT FROM customer WHERE `deleted`=:deleted AND age>30
$customers = Customer::find()->andWhere('age>30')->all();

// Use where() to ignore the default condition
// SELECT FROM customer WHERE age>30
$customers = Customer::find()->where('age>30')->all();


public static yii\db\ActiveQuery find ( )
return yii\db\ActiveQuery

The newly created yii\db\ActiveQuery instance.

                public static function find()
{
    return Yii::createObject(ActiveQuery::className(), [get_called_class()]);
}

            
findAll() public static method

Defined in: yii\db\BaseActiveRecord::findAll()

Returns a list of active record models that match the specified primary key value(s) or a set of column values.

The method accepts:

  • a scalar value (integer or string): query by a single primary key value and return an array containing the corresponding record (or an empty array if not found).
  • a non-associative array: query by a list of primary key values and return the corresponding records (or an empty array if none was found). Note that an empty condition will result in an empty result as it will be interpreted as a search for primary keys and not an empty WHERE condition.
  • an associative array of name-value pairs: query by a set of attribute values and return an array of records matching all of them (or an empty array if none was found). Note that ['id' => 1, 2] is treated as a non-associative array. Column names are limited to current records table columns for SQL DBMS, or filtered otherwise to be limted to simple filter conditions.
  • a yii\db\Expression: The expression will be used directly. (@since 2.0.37)

This method will automatically call the all() method and return an array of ActiveRecord instances.

Note: As this is a short-hand method only, using more complex conditions, like ['!=', 'id', 1] will not work. If you need to specify more complex conditions, use find() in combination with where() instead.

See the following code for usage examples:

// find the customers whose primary key value is 10
$customers = Customer::findAll(10);

// the above code is equivalent to:
$customers = Customer::find()->where(['id' => 10])->all();

// find the customers whose primary key value is 10, 11 or 12.
$customers = Customer::findAll([10, 11, 12]);

// the above code is equivalent to:
$customers = Customer::find()->where(['id' => [10, 11, 12]])->all();

// find customers whose age is 30 and whose status is 1
$customers = Customer::findAll(['age' => 30, 'status' => 1]);

// the above code is equivalent to:
$customers = Customer::find()->where(['age' => 30, 'status' => 1])->all();

If you need to pass user input to this method, make sure the input value is scalar or in case of array condition, make sure the array structure can not be changed from the outside:

// yii\web\Controller ensures that $id is scalar
public function actionView($id)
{
    $model = Post::findOne($id);

// do NOT use the following code! it is possible to inject an array condition to filter by arbitrary column values!
$model = Post::findOne(Yii::$app->request->get('id'));
public static static[] findAll ( $condition )
$condition mixed

Primary key value or a set of column values

return yii\db\BaseActiveRecord[]

An array of ActiveRecord instances, or an empty array if nothing matches.

                public static function findAll($condition)
{
    return static::findByCondition($condition)->all();
}

            
findBySql() public static method

Defined in: yii\db\ActiveRecord::findBySql()

Creates an yii\db\ActiveQuery instance with a given SQL statement.

Note that because the SQL statement is already specified, calling additional query modification methods (such as where(), order()) on the created yii\db\ActiveQuery instance will have no effect. However, calling with(), asArray() or indexBy() is still fine.

Below is an example:

$customers = Customer::findBySql('SELECT * FROM customer')->all();
public static yii\db\ActiveQuery findBySql ( $sql, $params = [] )
$sql string

The SQL statement to be executed

$params array

Parameters to be bound to the SQL statement during execution.

return yii\db\ActiveQuery

The newly created yii\db\ActiveQuery instance

                public static function findBySql($sql, $params = [])
{
    $query = static::find();
    $query->sql = $sql;
    return $query->params($params);
}

            
findOne() public static method

Defined in: yii\db\BaseActiveRecord::findOne()

Returns a single active record model instance by a primary key or an array of column values.

The method accepts:

  • a scalar value (integer or string): query by a single primary key value and return the corresponding record (or null if not found).
  • a non-associative array: query by a list of primary key values and return the first record (or null if not found).
  • an associative array of name-value pairs: query by a set of attribute values and return a single record matching all of them (or null if not found). Note that ['id' => 1, 2] is treated as a non-associative array. Column names are limited to current records table columns for SQL DBMS, or filtered otherwise to be limited to simple filter conditions.
  • a yii\db\Expression: The expression will be used directly. (@since 2.0.37)

That this method will automatically call the one() method and return an ActiveRecord instance.

Note: As this is a short-hand method only, using more complex conditions, like ['!=', 'id', 1] will not work. If you need to specify more complex conditions, use find() in combination with where() instead.

See the following code for usage examples:

// find a single customer whose primary key value is 10
$customer = Customer::findOne(10);

// the above code is equivalent to:
$customer = Customer::find()->where(['id' => 10])->one();

// find the customers whose primary key value is 10, 11 or 12.
$customers = Customer::findOne([10, 11, 12]);

// the above code is equivalent to:
$customers = Customer::find()->where(['id' => [10, 11, 12]])->one();

// find the first customer whose age is 30 and whose status is 1
$customer = Customer::findOne(['age' => 30, 'status' => 1]);

// the above code is equivalent to:
$customer = Customer::find()->where(['age' => 30, 'status' => 1])->one();

If you need to pass user input to this method, make sure the input value is scalar or in case of array condition, make sure the array structure can not be changed from the outside:

// yii\web\Controller ensures that $id is scalar
public function actionView($id)
{
    $model = Post::findOne($id);
    // ...
}

// explicitly specifying the colum to search, passing a scalar or array here will always result in finding a single record
$model = Post::findOne(['id' => Yii::$app->request->get('id')]);

// do NOT use the following code! it is possible to inject an array condition to filter by arbitrary column values!
$model = Post::findOne(Yii::$app->request->get('id'));
public static static|null findOne ( $condition )
$condition mixed

Primary key value or a set of column values

return yii\db\BaseActiveRecord|null

ActiveRecord instance matching the condition, or null if nothing matches.

                public static function findOne($condition)
{
    return static::findByCondition($condition)->one();
}

            
formName() public method

Defined in: yii\base\Model::formName()

Returns the form name that this model class should use.

The form name is mainly used by yii\widgets\ActiveForm to determine how to name the input fields for the attributes in a model. If the form name is "A" and an attribute name is "b", then the corresponding input name would be "A[b]". If the form name is an empty string, then the input name would be "b".

The purpose of the above naming schema is that for forms which contain multiple different models, the attributes of each model are grouped in sub-arrays of the POST-data and it is easier to differentiate between them.

By default, this method returns the model class name (without the namespace part) as the form name. You may override it when the model is used in different forms.

See also load().

public string formName ( )
return string

The form name of this model class.

    }
    return $tableSchema;
}

            
getValidators() public method

Defined in: yii\base\Model::getValidators()

Returns all the validators declared in rules().

This method differs from getActiveValidators() in that the latter only returns the validators applicable to the current $scenario.

Because this method returns an ArrayObject object, you may manipulate it by inserting or removing validators (useful in model behaviors). For example,

$model->validators[] = $newValidator;
public ArrayObject|yii\validators\Validator[] getValidators ( )
return ArrayObject|yii\validators\Validator[]

All the validators declared in the model.

                public function getValidators()

    });
}

            
insert() public method

Defined in: yii\db\ActiveRecord::insert()

Inserts a row into the associated database table using the attribute values of this record.

This method performs the following steps in order:

  1. call beforeValidate() when $runValidation is true. If beforeValidate() returns false, the rest of the steps will be skipped;
  2. call afterValidate() when $runValidation is true. If validation failed, the rest of the steps will be skipped;
  3. call beforeSave(). If beforeSave() returns false, the rest of the steps will be skipped;
  4. insert the record into database. If this fails, it will skip the rest of the steps;
  5. call afterSave();

In the above step 1, 2, 3 and 5, events EVENT_BEFORE_VALIDATE, EVENT_AFTER_VALIDATE, EVENT_BEFORE_INSERT, and EVENT_AFTER_INSERT will be raised by the corresponding methods.

Only the changed attribute values will be inserted into database.

If the table's primary key is auto-incremental and is null during insertion, it will be populated with the actual value after insertion.

For example, to insert a customer record:

$customer = new Customer;
$customer->name = $name;
$customer->email = $email;
$customer->insert();
public boolean insert ( $runValidation true, $attributes null )
$runValidation boolean

Whether to perform validation (calling validate()) before saving the record. Defaults to true. If the validation fails, the record will not be saved to the database and this method will return false.

$attributes array|null

List of attributes that need to be saved. Defaults to null, meaning all attributes that are loaded from DB will be saved.

return boolean

Whether the attributes are valid and the record is inserted successfully.

throws Throwable

in case insert failed.

                public function insert($runValidation = true, $attributes = null)
{
    if ($runValidation && !$this->validate($attributes)) {
        Yii::info('Model not inserted due to validation error.', __METHOD__);
        return false;
    }
    if (!$this->isTransactional(self::OP_INSERT)) {
        return $this->insertInternal($attributes);
    }

    try {
        $result = $this->insertInternal($attributes);
        if ($result === false) {
            $transaction->rollBack();
        } else {
            $transaction->commit();
        }
        return $result;
    } catch (\Exception $e) {
        $transaction->rollBack();

        throw $e;
    }
}

    }
    return self::$_instances[$className];
}

            
instantiate() public static method

Defined in: yii\db\BaseActiveRecord::instantiate()

Creates an active record instance.

This method is called together with populateRecord() by yii\db\ActiveQuery. It is not meant to be used for creating new records directly.

You may override this method if the instance being created depends on the row data to be populated into the record. For example, by creating a record based on the value of a column, you may implement the so-called single-table inheritance mapping.

public static static instantiate ( $row )
$row array

        if ($identical) {
            return $this->_attributes[$name] !== $this->_oldAttributes[$name];
        }
        return $this->_attributes[$name] != $this->_oldAttributes[$name];
    }
    return isset($this->_attributes[$name]) || isset($this->_oldAttributes[$name]);
}

            
isAttributeRequired() public method

Defined in: yii\base\Model::isAttributeRequired()

Returns a value indicating whether the attribute is required.

This is determined by checking if the attribute is associated with a required validation rule in the current $scenario.

Note that when the validator has a conditional validation applied using $when this method will return false regardless of the when condition because it may be called be before the model is loaded with data.

public boolean isAttributeRequired ( $attribute )

return boolean

Whether the attribute is required

                public function isAttributeRequired($attribute)

    if (count($keys) === count($pks)) {
        return count(array_intersect($keys, $pks)) === count($pks);
    }
    return false;
}

    return isset($transactions[$scenario]) && ($transactions[$scenario] & $operation);
}

            
link() public method

Defined in: yii\db\BaseActiveRecord::link()

Establishes the relationship between two models.

The relationship is established by setting the foreign key value(s) in one model to be the corresponding primary key value(s) in the other model. The model with the foreign key will be saved into database without performing validation and without events/behaviors.

If the relationship involves a junction table, a new row will be inserted into the junction table which contains the primary key values from both models.

Note that this method requires that the primary key value is not null.

throws yii\base\InvalidCallException

if the method is unable to link two models.

load() public method

Defined in: yii\base\Model::load()

Populates the model with input data.

This method provides a convenient shortcut for:

if (isset($_POST['FormName'])) {
    $model->attributes = $_POST['FormName'];
    if ($model->save()) {
        // handle success
    }
}

which, with load() can be written as:

if ($model->load($_POST) && $model->save()) {
    // handle success
}

load() gets the 'FormName' from the model's formName() method (which you may override), unless the $formName parameter is given. If the form name is empty, load() populates the model with the whole of $data, instead of $data['FormName'].

Note, that the data being populated is subject to the safety check by setAttributes().

public boolean load ( $data, $formName null )
$data array

The data array to load, typically $_POST or $_GET.

$formName string|null

The form name to use to load the data into the model, empty string when form not use. If not set, formName() is used.

return boolean

Whether load() found the expected form in $data.

{
    $scope = $formName === null ? $this->formName() : $formName;
    if ($scope === '' && !empty($data)) {
        $this->setAttributes($data);
        return true;
    } elseif (isset($data[$scope])) {
        $this->setAttributes($data[$scope]);
        return true;
    }
    return false;
}

            
loadDefaultValues() public method

Defined in: yii\db\ActiveRecord::loadDefaultValues()

Loads default values from database table schema.

You may call this method to load default values after creating a new instance:

// class Customer extends \yii\db\ActiveRecord
$customer = new Customer();
$customer->loadDefaultValues();
public $this loadDefaultValues ( $skipIfSet true )
$skipIfSet boolean

Whether existing value should be preserved. This will only set defaults for attributes that are null.

return $this

The model instance itself.

                public function loadDefaultValues($skipIfSet = true)
{
    $columns = static::getTableSchema()->columns;
    foreach ($this->attributes() as $name) {
        if (isset($columns[$name])) {
            $defaultValue = $columns[$name]->defaultValue;
            if ($defaultValue !== null && (!$skipIfSet || $this->getAttribute($name) === null)) {
                $this->setAttribute($name, $defaultValue);
            }
        }
    }
    return $this;
}

            
loadMultiple() public static method

Defined in: yii\base\Model::loadMultiple()

Populates a set of models with the data from end user.

This method is mainly used to collect tabular data input. The data to be loaded for each model is $data[formName][index], where formName refers to the value of formName(), and index the index of the model in the $models array. If formName() is empty, $data[index] will be used to populate each model. The data being populated to each model is subject to the safety check by setAttributes().

public static boolean loadMultiple ( $models, $data, $formName null )
$models array

The models to be populated. Note that all models should have the same class.

$data array

The data array. This is usually $_POST or $_GET, but can also be any valid array supplied by end user.

$formName string|null

The form name to be used for loading the data into the models. If not set, it will use the formName() value of the first model in $models. This parameter is available since version 2.0.1.

return boolean

Whether at least one of the models is successfully populated.

                public static function loadMultiple($models, $data, $formName = null)
{
    if ($formName === null) {

        $first = reset($models);
        if ($first === false) {
            return false;
        }
        $formName = $first->formName();
    }
    $success = false;
    foreach ($models as $i => $model) {

        unset($this->_events[$name], $this->_eventWildcards[$name]);
        return true;
    }
    $removed = false;
    // plain event names

            return true;
        }
    }
    // wildcard event names

    } else {
        unset($this->$offset);
    }
}

            
on() public method

Defined in: yii\base\Component::on()

Attaches an event handler to an event.

The event handler must be a valid PHP callback. The following are some examples:

function ($event) { ... }         // anonymous function
[$object, 'handleClick']          // $object->handleClick()
['Page', 'handleClick']           // Page::handleClick()
'handleClick'                     // global function handleClick()

The event handler must be defined with the following signature,

function ($event)

where $event is an yii\base\Event object which includes parameters associated with the event.

Since 2.0.14 you can specify event name as a wildcard pattern:

$component->on('event.group.*', function ($event) {
    Yii::trace($event->name . ' is triggered.');
});

See also off().

public void on ( $name, $handler, $data null, $append true )

                public function on($name, $handler, $data = null, $append = true)
{
    $this->ensureBehaviors();
    if (strpos($name, '*') !== false) {
        if ($append || empty($this->_eventWildcards[$name])) {
            $this->_eventWildcards[$name][] = [$handler, $data];
        } else {
            array_unshift($this->_eventWildcards[$name], [$handler, $data]);
        }
        return;
    }
    if ($append || empty($this->_events[$name])) {
        $this->_events[$name][] = [$handler, $data];
    } else {
        array_unshift($this->_events[$name], [$handler, $data]);
    }
}

            
onUnsafeAttribute() public method

Defined in: yii\base\Model::onUnsafeAttribute()

This method is invoked when an unsafe attribute is being massively assigned.

The default implementation will log a warning message if YII_DEBUG is on. It does nothing otherwise.

public void onUnsafeAttribute ( $name, $value )
$name string

The unsafe attribute name

$value mixed

The attribute value

                public function onUnsafeAttribute($name, $value)
{

    }
}

            
optimisticLock() public method

Defined in: yii\db\BaseActiveRecord::optimisticLock()

Returns the name of the column that stores the lock version for implementing optimistic locking.

Optimistic locking allows multiple users to access the same record for edits and avoids potential conflicts. In case when a user attempts to save the record upon some staled data (because another user has modified the data), a yii\db\StaleObjectException exception will be thrown, and the update or deletion is skipped.

Optimistic locking is only supported by update() and delete().

To use Optimistic locking:

  1. Create a column to store the version number of each row. The column type should be BIGINT DEFAULT 0. Override this method to return the name of this column.
  2. Ensure the version value is submitted and loaded to your model before any update or delete. Or add OptimisticLockBehavior to your model class in order to automate the process.
  3. In the Web form that collects the user input, add a hidden field that stores the lock version of the record being updated.
  4. In the controller action that does the data updating, try to catch the yii\db\StaleObjectException and implement necessary business logic (e.g. merging the changes, prompting stated data) to resolve the conflict.
public string|null optimisticLock ( )
return string|null

The column name that stores the lock version of a table row. If null is returned (default implemented), optimistic locking will not be supported.

                public function optimisticLock()
{
    return null;
}

            
populateRecord() public static method

Defined in: yii\db\ActiveRecord::populateRecord()

Populates an active record object using a row of data from the database/storage.

This is an internal method meant to be called to create active record objects after fetching data from the database. It is mainly used by yii\db\ActiveQuery to populate the query results into active records.

When calling this method manually you should call afterFind() on the created record to trigger the afterFind Event.

public static void populateRecord ( $record, $row )
$record yii\db\BaseActiveRecord

The record to be populated. In most cases this will be an instance created by instantiate() beforehand.

$row array

Attribute values (name => value)

                public static function populateRecord($record, $row)
{
    $columns = static::getTableSchema()->columns;
    foreach ($row as $name => $value) {
        if (isset($columns[$name])) {
            $row[$name] = $columns[$name]->phpTypecast($value);
        }
    }
    parent::populateRecord($record, $row);
}

            
populateRelation() public method

Defined in: yii\db\BaseActiveRecord::populateRelation()

Populates the named relation with the related records.

Note that this method does not check if the relation exists or not.

See also getRelation().

public void populateRelation ( $name, $records )
$name string

The relation name, e.g. orders for a relation defined via getOrders() method (case-sensitive).

$records yii\db\ActiveRecordInterface|array|null

The related records to be populated into the relation.

                public function populateRelation($name, $records)
{
    foreach ($this->_relationsDependencies as &$relationNames) {
        unset($relationNames[$name]);
    }
    $this->_related[$name] = $records;
}

            
primaryKey() public static method

Defined in: yii\db\ActiveRecord::primaryKey()

Returns the primary key name(s) for this AR class.

The default implementation will return the primary key(s) as declared in the DB table that is associated with this AR class.

If the DB table does not declare any primary key, you should override this method to return the attributes that you want to use as primary keys for this AR class.

Note that an array should be returned even for a table with single primary key.

public static string[] primaryKey ( )
return string[]

The primary keys of the associated database table.

                public static function primaryKey()
{
    return static::getTableSchema()->primaryKey;
}

            
refresh() public method

Defined in: yii\db\ActiveRecord::refresh()

Repopulates this active record with the latest data.

If the refresh is successful, an EVENT_AFTER_REFRESH event will be triggered. This event is available since version 2.0.8.

public boolean refresh ( )
return boolean

Whether the row still exists in the database. If true, the latest data will be populated to this active record. Otherwise, this record will remain unchanged.

                public function refresh()
{
    $query = static::find();
    $tableName = key($query->getTablesUsedInFrom());
    $pk = [];
    // disambiguate column names in case ActiveQuery adds a JOIN
    foreach ($this->getPrimaryKey(true) as $key => $value) {
        $pk[$tableName . '.' . $key] = $value;
    }
    $query->where($pk);
    /* @var $record BaseActiveRecord */
    $record = $query->noCache()->one();
    return $this->refreshInternal($record);
}

            
refreshInternal() protected method (available since version 2.0.13)

Defined in: yii\db\BaseActiveRecord::refreshInternal()

Repopulates this active record with the latest data from a newly fetched instance.

See also refresh().

protected boolean refreshInternal ( $record )
$record yii\db\BaseActiveRecord

The record to take attributes from.

return boolean

Whether refresh was successful.

                protected function refreshInternal($record)
{
    if ($record === null) {
        return false;
    }
    foreach ($this->attributes() as $name) {
        $this->_attributes[$name] = isset($record->_attributes[$name]) ? $record->_attributes[$name] : null;
    }
    $this->_oldAttributes = $record->_oldAttributes;
    $this->_related = [];
    $this->_relationsDependencies = [];
    $this->afterRefresh();
    return true;
}

            
resolveFields() protected method

Defined in: yii\base\ArrayableTrait::resolveFields()

Determines which fields can be returned by toArray().

This method will first extract the root fields from the given fields. Then it will check the requested root fields against those declared in fields() and extraFields() to determine which fields can be returned.

protected array resolveFields ( array $fields, array $expand )
$fields array

The fields being requested for exporting

$expand array

The additional fields being requested for exporting

return array

The list of fields to be exported. The array keys are the field names, and the array values are the corresponding object property names or PHP callables returning the field values.

                protected function resolveFields(array $fields, array $expand)
{
    $fields = $this->extractRootFields($fields);
    $expand = $this->extractRootFields($expand);
    $result = [];
    foreach ($this->fields() as $field => $definition) {
        if (is_int($field)) {
            $field = $definition;
        }
        if (empty($fields) || in_array($field, $fields, true)) {
            $result[$field] = $definition;
        }
    }
    if (empty($expand)) {
        return $result;
    }
    foreach ($this->extraFields() as $field => $definition) {
        if (is_int($field)) {
            $field = $definition;
        }
        if (in_array($field, $expand, true)) {
            $result[$field] = $definition;
        }
    }
    return $result;
}

            
rules() public method

Returns the validation rules for attributes.

Validation rules are used by validate() to check if attribute values are valid. Child classes may override this method to declare different validation rules.

Each rule is an array with the following structure:

[
    ['attribute1', 'attribute2'],
    'validator type',
    'on' => ['scenario1', 'scenario2'],
    //...other parameters...
]

where

  • attribute list: required, specifies the attributes array to be validated, for single attribute you can pass a string;
  • validator type: required, specifies the validator to be used. It can be a built-in validator name, a method name of the model class, an anonymous function, or a validator class name.
  • on: optional, specifies the scenarios array in which the validation rule can be applied. If this option is not set, the rule will apply to all scenarios.
  • additional name-value pairs can be specified to initialize the corresponding validator properties. Please refer to individual validator class API for possible properties.

A validator can be either an object of a class extending yii\validators\Validator, or a model class method (called inline validator) that has the following signature:

// $params refers to validation parameters given in the rule
function validatorName($attribute, $params)

In the above $attribute refers to the attribute currently being validated while $params contains an array of validator configuration options such as max in case of string validator. The value of the attribute currently being validated can be accessed as $this->$attribute. Note the $ before attribute; this is taking the value of the variable $attribute and using it as the name of the property to access.

Yii also provides a set of built-in validators. Each one has an alias name which can be used when specifying a validation rule.

Below are some examples:

[
    // built-in "required" validator
    [['username', 'password'], 'required'],
    // built-in "string" validator customized with "min" and "max" properties
    ['username', 'string', 'min' => 3, 'max' => 12],
    // built-in "compare" validator that is used in "register" scenario only
    ['password', 'compare', 'compareAttribute' => 'password2', 'on' => 'register'],
    // an inline validator defined via the "authenticate()" method in the model class
    ['password', 'authenticate', 'on' => 'login'],
    // a validator of class "DateRangeValidator"
    ['dateRange', 'DateRangeValidator'],
];

Note, in order to inherit rules defined in the parent class, a child class needs to merge the parent rules with child rules using functions such as array_merge().

public array rules ( )
return array

Validation rules

                public function rules()
{
    return [
        [['module_name'], 'required'],
        [['action_params'], 'string'],
        [['module_name', 'controller_name', 'action_name'], 'string', 'max' => 255],
    ];
}

            
safeAttributes() public method

Defined in: yii\base\Model::safeAttributes()

Returns the attribute names that are safe to be massively assigned in the current scenario.

public string[] safeAttributes ( )
return string[]

Safe attribute names

                public function safeAttributes()
{
    $scenario = $this->getScenario();
    $scenarios = $this->scenarios();
    if (!isset($scenarios[$scenario])) {
        return [];
    }
    $attributes = [];
    foreach ($scenarios[$scenario] as $attribute) {
        if (strncmp($attribute, '!', 1) !== 0 && !in_array('!' . $attribute, $scenarios[$scenario])) {
            $attributes[] = $attribute;
        }
    }
    return $attributes;
}

            
save() public method

Defined in: yii\db\BaseActiveRecord::save()

Saves the current record.

This method will call insert() when $isNewRecord is true, or update() when $isNewRecord is false.

For example, to save a customer record:

$customer = new Customer; // or $customer = Customer::findOne($id);
$customer->name = $name;
$customer->email = $email;
$customer->save();
public boolean save ( $runValidation true, $attributeNames null )
$runValidation boolean

Whether to perform validation (calling validate()) before saving the record. Defaults to true. If the validation fails, the record will not be saved to the database and this method will return false.

$attributeNames array|null

List of attribute names that need to be saved. Defaults to null, meaning all attributes that are loaded from DB will be saved.

return boolean

Whether the saving succeeded (i.e. no validation errors occurred).

                public function save($runValidation = true, $attributeNames = null)
{
    if ($this->getIsNewRecord()) {
        return $this->insert($runValidation, $attributeNames);
    }
    return $this->update($runValidation, $attributeNames) !== false;
}

            
scenarios() public method

Defined in: yii\base\Model::scenarios()

Returns a list of scenarios and the corresponding active attributes.

An active attribute is one that is subject to validation in the current scenario. The returned array should be in the following format:

[
    'scenario1' => ['attribute11', 'attribute12', ...],
    'scenario2' => ['attribute21', 'attribute22', ...],
    ...
]

By default, an active attribute is considered safe and can be massively assigned. If an attribute should NOT be massively assigned (thus considered unsafe), please prefix the attribute with an exclamation character (e.g. '!rank').

The default implementation of this method will return all scenarios found in the rules() declaration. A special scenario named SCENARIO_DEFAULT will contain all attributes found in the rules(). Each scenario will be associated with the attributes that are being validated by the validation rules that apply to the scenario.

public array scenarios ( )
return array

A list of scenarios and the corresponding active attributes.

                public function scenarios()
{
    $scenarios = [self::SCENARIO_DEFAULT => []];

        }
    }
    $names = array_keys($scenarios);
    foreach ($this->getValidators() as $validator) {
        if (empty($validator->on) && empty($validator->except)) {
            foreach ($names as $name) {
                foreach ($validator->attributes as $attribute) {
                    $scenarios[$name][$attribute] = true;
                }
            }

                if (!in_array($name, $validator->except, true)) {
                    foreach ($validator->attributes as $attribute) {
                        $scenarios[$name][$attribute] = true;
                    }

                public function setController(Controller $controller)
{
    $this->_controller = $controller;
}

            
setIsNewRecord() public method

Defined in: yii\db\BaseActiveRecord::setIsNewRecord()

Sets the value indicating whether the record is new.

See also getIsNewRecord().

public void setIsNewRecord ( $value )
$value boolean

Whether the record is new and should be inserted when calling save().

                public function setIsNewRecord($value)
{
    $this->_oldAttributes = $value ? null : $this->_attributes;
}

            
setOldAttribute() public method

Defined in: yii\db\BaseActiveRecord::setOldAttribute()

Sets the old value of the named attribute.

See also hasAttribute().

public void setOldAttribute ( $name, $value )
$name string

The attribute name

$value mixed

The old attribute value.

throws yii\base\InvalidArgumentException

if the named attribute does not exist.

                public function setOldAttribute($name, $value)
{
    if (isset($this->_oldAttributes[$name]) || $this->hasAttribute($name)) {
        $this->_oldAttributes[$name] = $value;
    } else {
        throw new InvalidArgumentException(get_class($this) . ' has no attribute named "' . $name . '".');
    }
}

            
setOldAttributes() public method

Defined in: yii\db\BaseActiveRecord::setOldAttributes()

Sets the old attribute values.

All existing old attribute values will be discarded.

public void setOldAttributes ( $values )
$values array|null

Old attribute values to be set. If set to null this record is considered to be new.

                public function setOldAttributes($values)
{
    $this->_oldAttributes = $values;
}

            
setOptions() public method

Defined in: luya\cms\base\NavItemType::setOptions()

Setter method for options.

public void setOptions ( array $options )
$options array

                public function setOptions(array $options)
{
    $this->_options = $options;
}

            
setScenario() public method

Defined in: yii\base\Model::setScenario()

Sets the scenario for the model.

Note that this method does not check if the scenario exists or not. The method validate() will perform this check.

public void setScenario ( $value )
$value string

The scenario that this model is in.

                public function setScenario($value)
{
    $this->_scenario = $value;
}

            
tableName() public static method

Declares the name of the database table associated with this AR class.

By default this method returns the class name as the table name by calling yii\helpers\Inflector::camel2id() with prefix yii\db\Connection::$tablePrefix. For example if yii\db\Connection::$tablePrefix is tbl_, Customer becomes tbl_customer, and OrderItem becomes tbl_order_item. You may override this method if the table is not named after this convention.

public static string tableName ( )
return string

The table name

                public static function tableName()
{
    return 'cms_nav_item_module';
}

            
toArray() public method

Defined in: yii\base\ArrayableTrait::toArray()

Converts the model into an array.

This method will first identify which fields to be included in the resulting array by calling resolveFields(). It will then turn the model into an array with these fields. If $recursive is true, any embedded objects will also be converted into arrays. When embedded objects are yii\base\Arrayable, their respective nested fields will be extracted and passed to toArray().

If the model implements the yii\web\Linkable interface, the resulting array will also have a _link element which refers to a list of links as specified by the interface.

public array toArray ( array $fields = [], array $expand = [], $recursive true )
$fields array

The fields being requested. If empty or if it contains '*', all fields as specified by fields() will be returned. Fields can be nested, separated with dots (.). e.g.: item.field.sub-field $recursive must be true for nested fields to be extracted. If $recursive is false, only the root fields will be extracted.

$expand array

The additional fields being requested for exporting. Only fields declared in extraFields() will be considered. Expand can also be nested, separated with dots (.). e.g.: item.expand1.expand2 $recursive must be true for nested expands to be extracted. If $recursive is false, only the root expands will be extracted.

$recursive boolean

Whether to recursively return array representation of embedded objects.

return array

The array representation of the object

                public function toArray(array $fields = [], array $expand = [], $recursive = true)
{
    $data = [];
    foreach ($this->resolveFields($fields, $expand) as $field => $definition) {
        $attribute = is_string($definition) ? $this->$definition : $definition($this, $field);
        if ($recursive) {
            $nestedFields = $this->extractFieldsFor($fields, $field);
            $nestedExpand = $this->extractFieldsFor($expand, $field);
            if ($attribute instanceof Arrayable) {
                $attribute = $attribute->toArray($nestedFields, $nestedExpand);
            } elseif ($attribute instanceof \JsonSerializable) {
                $attribute = $attribute->jsonSerialize();
            } elseif (is_array($attribute)) {
                $attribute = array_map(
                    function ($item) use ($nestedFields, $nestedExpand) {
                        if ($item instanceof Arrayable) {
                            return $item->toArray($nestedFields, $nestedExpand);
                        } elseif ($item instanceof \JsonSerializable) {
                            return $item->jsonSerialize();
                        }
                        return $item;
                    },
                    $attribute
                );
            }
        }
        $data[$field] = $attribute;
    }
    if ($this instanceof Linkable) {
        $data['_links'] = Link::serialize($this->getLinks());
    }
    return $recursive ? ArrayHelper::toArray($data) : $data;
}

            
transactions() public method

Defined in: yii\db\ActiveRecord::transactions()

Declares which DB operations should be performed within a transaction in different scenarios.

The supported DB operations are: OP_INSERT, OP_UPDATE and OP_DELETE, which correspond to the insert(), update() and delete() methods, respectively. By default, these methods are NOT enclosed in a DB transaction.

In some scenarios, to ensure data consistency, you may want to enclose some or all of them in transactions. You can do so by overriding this method and returning the operations that need to be transactional. For example,

return [
    'admin' => self::OP_INSERT,
    'api' => self::OP_INSERT | self::OP_UPDATE | self::OP_DELETE,
    // the above is equivalent to the following:
    // 'api' => self::OP_ALL,

];

The above declaration specifies that in the "admin" scenario, the insert operation (insert()) should be done in a transaction; and in the "api" scenario, all the operations should be done in a transaction.

public array transactions ( )
return array

The declarations of transactional operations. The array keys are scenarios names, and the array values are the corresponding transaction operations.

                public function transactions()
{
    return [];
}

            
trigger() public method

Defined in: yii\base\Component::trigger()

Triggers an event.

This method represents the happening of an event. It invokes all attached handlers for the event including class-level handlers.

public void trigger ( $name, yii\base\Event $event null )
$name string

The event name

$event yii\base\Event|null

The event instance. If not set, a default yii\base\Event object will be created.

                public function trigger($name, Event $event = null)
{
    $this->ensureBehaviors();
    $eventHandlers = [];
    foreach ($this->_eventWildcards as $wildcard => $handlers) {
        if (StringHelper::matchWildcard($wildcard, $name)) {
            $eventHandlers[] = $handlers;
        }
    }
    if (!empty($this->_events[$name])) {
        $eventHandlers[] = $this->_events[$name];
    }
    if (!empty($eventHandlers)) {
        $eventHandlers = call_user_func_array('array_merge', $eventHandlers);
        if ($event === null) {
            $event = new Event();
        }
        if ($event->sender === null) {
            $event->sender = $this;
        }
        $event->handled = false;
        $event->name = $name;
        foreach ($eventHandlers as $handler) {
            $event->data = $handler[1];
            call_user_func($handler[0], $event);
            // stop further handling if the event is handled
            if ($event->handled) {
                return;
            }
        }
    }
    // invoke class-level attached handlers
    Event::trigger($this, $name, $event);
}

            
unlink() public method

Defined in: yii\db\BaseActiveRecord::unlink()

Destroys the relationship between two models.

The model with the foreign key of the relationship will be deleted if $delete is true. Otherwise, the foreign key will be set null and the model will be saved without validation.

public void unlink ( $name, $model, $delete false )
$name string

The case sensitive name of the relationship, e.g. orders for a relation defined via getOrders() method.

$model yii\db\ActiveRecordInterface

The model to be unlinked from the current one. You have to make sure that the model is really related with the current model as this method does not check this.

$delete boolean

Whether to delete the model that contains the foreign key. If false, the model's foreign key will be set null and saved. If true, the model containing the foreign key will be deleted.

throws yii\base\InvalidCallException

if the models cannot be unlinked

throws yii\db\Exception
throws yii\db\StaleObjectException

unlinkAll() public method

Defined in: yii\db\BaseActiveRecord::unlinkAll()

Destroys the relationship in current model.

The model with the foreign key of the relationship will be deleted if $delete is true. Otherwise, the foreign key will be set null and the model will be saved without validation.

Note that to destroy the relationship without removing records make sure your keys can be set to null

public void unlinkAll ( $name, $delete false )
$name string

The case sensitive name of the relationship, e.g. orders for a relation defined via getOrders() method.

$delete boolean

Whether to delete the model that contains the foreign key.

Note that the deletion will be performed using deleteAll(), which will not trigger any events on the related models. If you need EVENT_BEFORE_DELETE or EVENT_AFTER_DELETE to be triggered, you need to find the models first and then call delete() on each of them.

                public function unlinkAll($name, $delete = false)

    unset($this->_related[$name]);
}

            
update() public method

Defined in: yii\db\ActiveRecord::update()

Saves the changes to this active record into the associated database table.

This method performs the following steps in order:

  1. call beforeValidate() when $runValidation is true. If beforeValidate() returns false, the rest of the steps will be skipped;
  2. call afterValidate() when $runValidation is true. If validation failed, the rest of the steps will be skipped;
  3. call beforeSave(). If beforeSave() returns false, the rest of the steps will be skipped;
  4. save the record into database. If this fails, it will skip the rest of the steps;
  5. call afterSave();

In the above step 1, 2, 3 and 5, events EVENT_BEFORE_VALIDATE, EVENT_AFTER_VALIDATE, EVENT_BEFORE_UPDATE, and EVENT_AFTER_UPDATE will be raised by the corresponding methods.

Only the changed attribute values will be saved into database.

For example, to update a customer record:

$customer = Customer::findOne($id);
$customer->name = $name;
$customer->email = $email;
$customer->update();

Note that it is possible the update does not affect any row in the table. In this case, this method will return 0. For this reason, you should use the following code to check if update() is successful or not:

if ($customer->update() !== false) {
    // update successful
} else {
    // update failed
}
public integer|false update ( $runValidation true, $attributeNames null )
$runValidation boolean

Whether to perform validation (calling validate()) before saving the record. Defaults to true. If the validation fails, the record will not be saved to the database and this method will return false.

$attributeNames array|null

List of attributes that need to be saved. Defaults to null, meaning all attributes that are loaded from DB will be saved.

return integer|false

The number of rows affected, or false if validation fails or beforeSave() stops the updating process.

throws yii\db\StaleObjectException

if optimistic locking is enabled and the data being updated is outdated.

throws Throwable

in case update failed.

                public function update($runValidation = true, $attributeNames = null)
{
    if ($runValidation && !$this->validate($attributeNames)) {
        Yii::info('Model not updated due to validation error.', __METHOD__);
        return false;
    }
    if (!$this->isTransactional(self::OP_UPDATE)) {
        return $this->updateInternal($attributeNames);
    }
    $transaction = static::getDb()->beginTransaction();
    try {
        $result = $this->updateInternal($attributeNames);
        if ($result === false) {
            $transaction->rollBack();
        } else {
            $transaction->commit();
        }
        return $result;
    } catch (\Exception $e) {
        $transaction->rollBack();
        throw $e;
    } catch (\Throwable $e) {
        $transaction->rollBack();
        throw $e;
    }
}

            
updateAll() public static method

Defined in: yii\db\ActiveRecord::updateAll()

Updates the whole table using the provided attribute values and conditions.

For example, to change the status to be 1 for all customers whose status is 2:

Customer::updateAll(['status' => 1], 'status = 2');

Warning: If you do not specify any condition, this method will update all rows in the table.

Note that this method will not trigger any events. If you need EVENT_BEFORE_UPDATE or EVENT_AFTER_UPDATE to be triggered, you need to find the models first and then call update() on each of them. For example an equivalent of the example above would be:

$models = Customer::find()->where('status = 2')->all();
foreach ($models as $model) {
    $model->status = 1;
    $model->update(false); // skipping validation as no user input is involved
}

For a large set of models you might consider using yii\db\ActiveQuery::each() to keep memory usage within limits.

public static integer updateAll ( $attributes, $condition '', $params = [] )
$attributes array

Attribute values (name-value pairs) to be saved into the table

$condition string|array

The conditions that will be put in the WHERE part of the UPDATE SQL. Please refer to yii\db\Query::where() on how to specify this parameter.

$params array

The parameters (name => value) to be bound to the query.

return integer

The number of rows updated

                public static function updateAll($attributes, $condition = '', $params = [])
{
    $command = static::getDb()->createCommand();
    $command->update(static::tableName(), $attributes, $condition, $params);
    return $command->execute();
}

            
updateAllCounters() public static method

Defined in: yii\db\ActiveRecord::updateAllCounters()

Updates the whole table using the provided counter changes and conditions.

For example, to increment all customers' age by 1,

Customer::updateAllCounters(['age' => 1]);

Note that this method will not trigger any events.

public static integer updateAllCounters ( $counters, $condition '', $params = [] )
$counters array

The counters to be updated (attribute name => increment value). Use negative values if you want to decrement the counters.

$condition string|array

The conditions that will be put in the WHERE part of the UPDATE SQL. Please refer to yii\db\Query::where() on how to specify this parameter.

$params array

The parameters (name => value) to be bound to the query. Do not name the parameters as :bp0, :bp1, etc., because they are used internally by this method.

return integer

The number of rows updated

                public static function updateAllCounters($counters, $condition = '', $params = [])
{
    $n = 0;
    foreach ($counters as $name => $value) {
        $counters[$name] = new Expression("[[$name]]+:bp{$n}", [":bp{$n}" => $value]);
        $n++;
    }
    $command = static::getDb()->createCommand();
    $command->update(static::tableName(), $counters, $condition, $params);
    return $command->execute();
}

            
updateAttributes() public method

Defined in: yii\db\BaseActiveRecord::updateAttributes()

Updates the specified attributes.

This method is a shortcut to update() when data validation is not needed and only a small set attributes need to be updated.

You may specify the attributes to be updated as name list or name-value pairs. If the latter, the corresponding attribute values will be modified accordingly. The method will then save the specified attributes into database.

Note that this method will not perform data validation and will not trigger events.

public integer updateAttributes ( $attributes )
$attributes array

The attributes (names or name-value pairs) to be updated

return integer

The number of rows affected.

                public function updateAttributes($attributes)

    foreach ($values as $name => $value) {
        $this->_oldAttributes[$name] = $this->_attributes[$name];
    }
    return $rows;
}

            
updateCounters() public method

Defined in: yii\db\BaseActiveRecord::updateCounters()

Updates one or several counter columns for the current AR object.

Note that this method differs from updateAllCounters() in that it only saves counters for the current AR object.

An example usage is as follows:

$post = Post::findOne($id);
$post->updateCounters(['view_count' => 1]);

See also updateAllCounters().

public boolean updateCounters ( $counters )
$counters array

The counters to be updated (attribute name => increment value) Use negative values if you want to decrement the counters.

return boolean

Whether the saving is successful

                public function updateCounters($counters)
{
    if (static::updateAllCounters($counters, $this->getOldPrimaryKey(true)) > 0) {
        foreach ($counters as $name => $value) {
            if (!isset($this->_attributes[$name])) {
                $this->_attributes[$name] = $value;
            } else {

validate() public method

Defined in: yii\base\Model::validate()

Performs the data validation.

This method executes the validation rules applicable to the current $scenario. The following criteria are used to determine whether a rule is currently applicable:

  • the rule must be associated with the attributes relevant to the current scenario;
  • the rules must be effective for the current scenario.

This method will call beforeValidate() and afterValidate() before and after the actual validation, respectively. If beforeValidate() returns false, the validation will be cancelled and afterValidate() will not be called.

Errors found during the validation can be retrieved via getErrors(), getFirstErrors() and getFirstError().

public boolean validate ( $attributeNames null, $clearErrors true )
$attributeNames string[]|string|null

Attribute name or list of attribute names that should be validated. If this parameter is empty, it means any attribute listed in the applicable validation rules should be validated.

$clearErrors boolean

Whether to call clearErrors() before performing validation

return boolean

Whether the validation is successful without any error.

throws yii\base\InvalidArgumentException

if the current scenario is unknown.

                public function validate($attributeNames = null, $clearErrors = true)
{
    if ($clearErrors) {
        $this->clearErrors();
    }
    if (!$this->beforeValidate()) {
        return false;
    }
    $scenarios = $this->scenarios();
    $scenario = $this->getScenario();
    if (!isset($scenarios[$scenario])) {
        throw new InvalidArgumentException("Unknown scenario: $scenario");
    }
    if ($attributeNames === null) {
        $attributeNames = $this->activeAttributes();
    }
    $attributeNames = (array)$attributeNames;
    foreach ($this->getActiveValidators() as $validator) {
        $validator->validateAttributes($this, $attributeNames);
    }
    $this->afterValidate();
    return !$this->hasErrors();
}

            
validateMultiple() public static method

Defined in: yii\base\Model::validateMultiple()

Validates multiple models.

This method will validate every model. The models being validated may be of the same or different types.

public static boolean validateMultiple ( $models, $attributeNames null )
$models array

The models to be validated

$attributeNames array|null

List of attribute names that should be validated. If this parameter is empty, it means any attribute listed in the applicable validation rules should be validated.

return boolean

Whether all models are valid. False will be returned if one or multiple models have validation error.

                public static function validateMultiple($models, $attributeNames = null)
{
    $valid = true;
    /* @var $model Model */
    foreach ($models as $model) {
        $valid = $model->validate($attributeNames) && $valid;
    }
    return $valid;
}
