Method Details

Hide inherited methods

__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

                public function __call($name, $params)
{
    $this->ensureBehaviors();
    foreach ($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\base\Component::__get()

Returns the value of a component property.

This method will check in the following order and act accordingly:

  • a property defined by a getter: return the getter result
  • a property of a behavior: return the behavior property value

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $value = $component->property;.

See also __set().

public mixed __get ( $name )
$name string

The property name

return mixed

The property value or the value of a behavior's property

throws yii\base\UnknownPropertyException

if the property is not defined

throws yii\base\InvalidCallException

if the property is write-only.

                public function __get($name)
{
    $getter = 'get' . $name;
    if (method_exists($this, $getter)) {
        // read property, e.g. getName()
        return $this->$getter();
    }
    // behavior property
    $this->ensureBehaviors();
    foreach ($this->_behaviors as $behavior) {
        if ($behavior->canGetProperty($name)) {
            return $behavior->$name;
        }
    }
    if (method_exists($this, 'set' . $name)) {
        throw new InvalidCallException('Getting write-only property: ' . get_class($this) . '::' . $name);
    }
    throw new UnknownPropertyException('Getting unknown property: ' . get_class($this) . '::' . $name);
}

            
__isset() public method

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

Checks if a property is set, i.e. defined and not null.

This method will check in the following order and act accordingly:

  • a property defined by a setter: return whether the property is set
  • a property of a behavior: return whether the property is set
  • return false for non existing properties

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing isset($component->property).

See also https://www.php.net/manual/en/function.isset.php.

public boolean __isset ( $name )
$name string

The property name or the event name

return boolean

Whether the named property is set

                public function __isset($name)
{
    $getter = 'get' . $name;
    if (method_exists($this, $getter)) {
        return $this->$getter() !== null;
    }
    // behavior property
    $this->ensureBehaviors();
    foreach ($this->_behaviors as $behavior) {
        if ($behavior->canGetProperty($name)) {
            return $behavior->$name !== null;
        }
    }
    return false;
}

            
__set() public method

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

Sets the value of a component property.

This method will check in the following order and act accordingly:

  • a property defined by a setter: set the property value
  • an event in the format of "on xyz": attach the handler to the event "xyz"
  • a behavior in the format of "as xyz": attach the behavior named as "xyz"
  • a property of a behavior: set the behavior property value

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $component->property = $value;.

See also __get().

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

The property name or the event name

$value mixed

The property value

throws yii\base\UnknownPropertyException

if the property is not defined

{
    $setter = 'set' . $name;
    if (method_exists($this, $setter)) {
        // set property
        $this->$setter($value);
        return;
    } elseif (strncmp($name, 'on ', 3) === 0) {

        $name = trim(substr($name, 3));
        $this->attachBehavior($name, $value instanceof Behavior ? $value : Yii::createObject($value));
        return;
    }

}

            
__unset() public method

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

Sets a component property to be null.

This method will check in the following order and act accordingly:

  • a property defined by a setter: set the property value to be null
  • a property of a behavior: set the property value to be null

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing unset($component->property).

See also https://www.php.net/manual/en/function.unset.php.

public void __unset ( $name )
$name string

The property name

throws yii\base\InvalidCallException

if the property is read only.

                public function __unset($name)

    if (method_exists($this, $setter)) {
        $this->$setter(null);
        return;
    }
    // behavior property
    $this->ensureBehaviors();
    foreach ($this->_behaviors as $behavior) {
        if ($behavior->canSetProperty($name)) {
            $behavior->$name = null;
            return;
        }
    }
    throw new InvalidCallException('Unsetting an unknown or read-only property: ' . get_class($this) . '::' . $name);
}

            
activeAttributes() public method

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

Returns the attribute names that are subject to validation in the current scenario.

public string[] activeAttributes ( )

Safe attribute names

                public function activeAttributes()
{
    $scenario = $this->getScenario();
    $scenarios = $this->scenarios();
    if (!isset($scenarios[$scenario])) {
        return [];
    }
    $attributes = array_keys(array_flip($scenarios[$scenario]));
    foreach ($attributes as $i => $attribute) {
        if (strncmp($attribute, '!', 1) === 0) {
            $attributes[$i] = substr($attribute, 1);
        }
    }
    return $attributes;
}

            
addError() public method

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

Adds a new error to the specified attribute.

public void addError ( $attribute, $error '' )
$attribute string

Attribute name

$error string

New error message

                public function addError($attribute, $error = '')
{
    $this->_errors[$attribute][] = $error;
}

            
addErrors() public method (available since version 2.0.2)

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

Adds a list of errors.

public void addErrors ( array $items )
$items array

A list of errors. The array keys must be attribute names. The array values should be error messages. If an attribute has multiple errors, these errors must be given in terms of an array. You may use the result of getErrors() as the value for this parameter.

                public function addErrors(array $items)
{
    foreach ($items as $attribute => $errors) {
        if (is_array($errors)) {
            foreach ($errors as $error) {
                $this->addError($attribute, $error);
            }
        } else {
            $this->addError($attribute, $errors);
        }
    }
}

            
afterValidate() public method

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

This method is invoked after validation ends.

The default implementation raises an afterValidate event. You may override this method to do postprocessing after validation. Make sure the parent implementation is invoked so that the event can be raised.

public void afterValidate ( )

                public function afterValidate()
{
    $this->trigger(self::EVENT_AFTER_VALIDATE);
}

            
attachBehavior() public method

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

Attaches a behavior to this component.

This method will create the behavior object based on the given configuration. After that, the behavior object will be attached to this component by calling the yii\base\Behavior::attach() method.

See also detachBehavior().

public yii\base\Behavior attachBehavior ( $name, $behavior )
$name string

The name of the behavior.

$behavior string|array|yii\base\Behavior

The behavior configuration. This can be one of the following:

return yii\base\Behavior

The behavior object

                public function attachBehavior($name, $behavior)
{
    $this->ensureBehaviors();
    return $this->attachBehaviorInternal($name, $behavior);
}

            
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 [
        'oldpass' => Module::t('model_user_oldpassword'),
        'newpassrepeat' => Module::t('aws_changepassword_new_pass_retry'),
        'newpass' => Module::t('aws_changepassword_new_pass'),
    ];
}

            
attributes() public method

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

Returns the list of attribute names.

By default, this method returns all public non-static properties of the class. You may override this method to change the default behavior.

public string[] attributes ( )
return string[]

List of attribute names.

                public function attributes()
{
    return array_keys(Yii::getObjectVars($this));
}

            
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

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

Returns a value indicating whether a property can be read.

A property can be read if:

  • the class has a getter 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 readable property of the given name (when $checkBehaviors is true).

See also canSetProperty().

public boolean canGetProperty ( $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

return boolean

                public function canGetProperty($name, $checkVars = true, $checkBehaviors = true)
{
    if (method_exists($this, 'get' . $name) || $checkVars && property_exists($this, $name)) {
        return true;
    } elseif ($checkBehaviors) {
        $this->ensureBehaviors();
        foreach ($this->_behaviors as $behavior) {
            if ($behavior->canGetProperty($name, $checkVars)) {
                return true;
            }
        }
    }
    return false;
}

            
canSetProperty() public method

Defined in: yii\base\Component::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).

See also canGetProperty().

public boolean canSetProperty ( $name, $checkVars true, $checkBehaviors true )
$name string

Checks if the password is valid and stores the new password.

public void checkAndStore ( )

                public function checkAndStore()
{
    if (!$this->user->validatePassword($this->oldpass)) {
        return $this->addError('oldpass', 'The previous old password is invalid.');

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()

    }
}

            
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);
}

            
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.

throws yii\base\InvalidConfigException

when form is defined with anonymous class and formName() method is not overridden.

                public function formName()
{
    $reflector = new ReflectionClass($this);
    if (PHP_VERSION_ID >= 70000 && $reflector->isAnonymous()) {
        throw new InvalidConfigException('The "formName()" method should be explicitly defined for anonymous models');
    }
    return $reflector->getShortName();
}

            
generateAttributeLabel() public method

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

Generates a user friendly attribute label based on the give attribute name.

public string generateAttributeLabel ( $name )
$name string

The column name

return string

The attribute label

                public function generateAttributeLabel($name)
{
    return Inflector::camel2words($name, true);

    $validators = [];
    foreach ($this->getValidators() as $validator) {
        if ($attribute === null) {
            $validatorAttributes = $validator->getValidationAttributes($activeAttributes);
            $attributeValid = !empty($validatorAttributes);
        } else {
            $attributeValid = in_array($attribute, $validator->getValidationAttributes($attribute), true);
        }
        if ($attributeValid && $validator->isActive($scenario)) {
            $validators[] = $validator;

    ]
]

                public function getErrors($attribute = null)

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.

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

All the validators declared in the model.

                public function getValidators()

    return false;
}

            
hasProperty() public method

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

Returns a value indicating whether a property is defined for this component.

A property is defined if:

  • the class has a getter or 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 property of the given name (when $checkBehaviors is true).

{
    return in_array($attribute, $this->activeAttributes(), true);
}

            
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 )
$attribute string

Attribute name

return boolean

Whether the attribute is required

                public function isAttributeRequired($attribute)

See also safeAttributes().

public boolean isAttributeSafe ( $attribute )
$attribute string

Attribute name

return boolean

    return in_array($attribute, $this->safeAttributes(), true);
}

            
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.

                public function load($data, $formName = null)
{
    $scope = $formName === null ? $this->formName() : $formName;
    if ($scope === '' && !empty($data)) {

        return true;
    }
    return false;
}

            
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) {
        /* @var $first Model|false */
        $first = reset($models);
        if ($first === false) {
            return false;
        }
        $formName = $first->formName();
    }
    $success = false;
    foreach ($models as $i => $model) {
        /* @var $model Model */
        if ($formName == '') {
            if (!empty($data[$i]) && $model->load($data[$i], '')) {
                $success = true;
            }
        } elseif (!empty($data[$formName][$i]) && $model->load($data[$formName][$i], '')) {
            $success = true;
        }
    }
    return $success;
}

            
off() public method

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

Detaches an existing event handler from this component.

This method is the opposite of on().

Note: in case wildcard pattern is passed for event name, only the handlers registered with this wildcard will be removed, while handlers registered with plain names matching this wildcard will remain.

See also on().

public boolean off ( $name, $handler null )
$name string

Event name

$handler callable|null

The event handler to be removed. If it is null, all handlers attached to the named event will be removed.

return boolean

{
    $this->ensureBehaviors();
    if (empty($this->_events[$name]) && empty($this->_eventWildcards[$name])) {
        return false;
    }
    if ($handler === null) {
        unset($this->_events[$name], $this->_eventWildcards[$name]);
        return true;
    }
    $removed = false;
    // plain event names
    if (isset($this->_events[$name])) {
        foreach ($this->_events[$name] as $i => $event) {
            if ($event[0] === $handler) {
                unset($this->_events[$name][$i]);
                $removed = true;
            }
        }

    }
    return $removed;
}

    return $this->$offset;
}

            
offsetSet() public method

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

}

            
offsetUnset() public method

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

This method is required by the SPL interface ArrayAccess. It is implicitly called when you use something like unset($model[$offset]).

public void offsetUnset ( $offset )
$offset string

The offset to unset element

                #[\ReturnTypeWillChange]
public function offsetUnset($offset)
{
    $this->$offset = null;
}

            
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 )
$name string

{
    $this->ensureBehaviors();
    if (strpos($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, $value)
{
    if (YII_DEBUG) {
        Yii::debug("Failed to set unsafe attribute '$name' in '" . get_class($this) . "'.", __METHOD__);
    }
}

            
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 [
        [['oldpass', 'newpass', 'newpassrepeat'], 'required'],
        [['newpass'], 'string', 'min' => '8'],
        [['newpass'], 'compare', 'compareAttribute' => 'newpassrepeat'],
    ];
}

            
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;
}

            
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 => []];

                    foreach ($validator->attributes as $attribute) {
                        $scenarios[$name][$attribute] = true;
                    }
                }
            }

    }
    return $scenarios;
}

Sets the attribute values in a massive way.

See also:

public void setAttributes ( $values, $safeOnly true )
$values array

Attribute values (name => value) to be assigned to the model.

$safeOnly boolean

Whether the assignments should only be done to the safe attributes. A safe attribute is one that is associated with a validation rule in the current $scenario.

                public function setAttributes($values, $safeOnly = true)
{
    if (is_array($values)) {
        $attributes = array_flip($safeOnly ? $this->safeAttributes() : $this->attributes());

        }
    }
}

            
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;

setUser() public method

Setter method for user.

public void setUser ( luya\admin\models\User $user )

    $this->_user = $user;
}

            
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)

                );
            }
        }
        $data[$field] = $attribute;
    }
    if ($this instanceof Linkable) {
        $data['_links'] = Link::serialize($this->getLinks());
    }
    return $recursive ? ArrayHelper::toArray($data) : $data;
}

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;
}
