Available since version2.0
Source Code https://github.com/yiisoft/yii2/blob/master/framework/grid/GridView.php

The GridView widget is used to display data in a grid.

It provides features like sorting, paging and also filtering the data.

A basic usage looks like the following:

<?= GridView::widget([
    'dataProvider' => $dataProvider,
    'columns' => [
        'id',
        'name',
        'created_at:datetime',
        // ...
    ],
]) ?>

The columns of the grid table are configured in terms of yii\grid\Column classes, which are configured via $columns.

The look and feel of a grid view can be customized using the large amount of properties.

For more details and usage information on GridView, see the guide article on data widgets.

Property Details

$afterRow public property

An anonymous function that is called once AFTER rendering each data model. It should have the similar signature as $rowOptions. The return result of the function will be rendered directly.

public Closure $afterRow null
$beforeRow public property

An anonymous function that is called once BEFORE rendering each data model. It should have the similar signature as $rowOptions. The return result of the function will be rendered directly.

public Closure $beforeRow null
$caption public property

The caption of the grid table

See also $captionOptions.

public string $caption null
$captionOptions public property

The HTML attributes for the caption element.

See also:

public array $captionOptions = []
$columns public property

Grid column configuration. Each array element represents the configuration for one particular grid column. For example,

[
    ['class' => SerialColumn::class],
    [
        'class' => DataColumn::class, // this line is optional
        'attribute' => 'name',
        'format' => 'text',
        'label' => 'Name',
    ],
    ['class' => CheckboxColumn::class],
]

If a column is of class yii\grid\DataColumn, the "class" element can be omitted.

As a shortcut format, a string may be used to specify the configuration of a data column which only contains attribute, format, and/or label options: "attribute:format:label". For example, the above "name" column can also be specified as: "name:text:Name". Both "format" and "label" are optional. They will take default values if absent.

Using the shortcut format the configuration for columns in simple cases would look like this:

[
    'id',
    'amount:currency:Total Amount',
    'created_at:datetime',
]

When using a $dataProvider with active records, you can also display values from related records, e.g. the name attribute of the author relation:

// shortcut syntax
'author.name',
// full syntax
[
    'attribute' => 'author.name',
    // ...
]
public array $columns = []
$dataColumnClass public property

The default data column class if the class name is not explicitly specified when configuring a data column. Defaults to 'yii\grid\DataColumn'.

public string $dataColumnClass null
$emptyCell public property

The HTML display when the content of a cell is empty. This property is used to render cells that have no defined content, e.g. empty footer or filter cells.

Note that this is not used by the yii\grid\DataColumn if a data item is null. In that case the nullDisplay property of the $formatter will be used to indicate an empty data value.

public string $emptyCell '&nbsp;'
$filterErrorOptions public property

The options for rendering every filter error message. This is mainly used by yii\helpers\Html::error() when rendering an error message next to every filter input field.

public array $filterErrorOptions = [
    
'class' => 'help-block',
]
$filterErrorSummaryOptions public property

The options for rendering the filter error summary. Please refer to yii\helpers\Html::errorSummary() for more details about how to specify the options.

See also renderErrors().

public array $filterErrorSummaryOptions = [
    
'class' => 'error-summary',
]
$filterModel public property

The model that keeps the user-entered filter data. When this property is set, the grid view will enable column-based filtering. Each data column by default will display a text field at the top that users can fill in to filter the data.

Note that in order to show an input field for filtering, a column must have its yii\grid\DataColumn::$attribute property set and the attribute should be active in the current scenario of $filterModel or have yii\grid\DataColumn::$filter set as the HTML code for the input field.

When this property is not set (null) the filtering feature is disabled.

$filterOnFocusOut public property (available since version 2.0.16)

Whatever to apply filters on losing focus. Leaves an ability to manage filters via yiiGridView JS

public boolean $filterOnFocusOut true
$filterPosition public property

Whether the filters should be displayed in the grid view. Valid values include:

  • FILTER_POS_HEADER: the filters will be displayed on top of each column's header cell.
  • FILTER_POS_BODY: the filters will be displayed right below each column's header cell.
  • FILTER_POS_FOOTER: the filters will be displayed below each column's footer cell.
public string $filterPosition self::FILTER_POS_BODY
$filterRowOptions public property

The HTML attributes for the filter row element.

See also yii\helpers\Html::renderTagAttributes() for details on how attributes are being rendered.

public array $filterRowOptions = [
    
'class' => 'filters',
]
$filterSelector public property

Additional jQuery selector for selecting filter input fields

public string $filterSelector null
$filterUrl public property

The URL for returning the filtering result. yii\helpers\Url::to() will be called to normalize the URL. If not set, the current controller action will be used. When the user makes change to any filter input, the current filtering inputs will be appended as GET parameters to this URL.

public string|array|null $filterUrl null
$footerRowOptions public property

The HTML attributes for the table footer row.

See also yii\helpers\Html::renderTagAttributes() for details on how attributes are being rendered.

$formatter public property

The formatter used to format model attribute values into displayable texts. This can be either an instance of yii\i18n\Formatter or an configuration array for creating the yii\i18n\Formatter instance. If this property is not set, the "formatter" application component will be used.

$headerRowOptions public property

The HTML attributes for the table header row.

See also yii\helpers\Html::renderTagAttributes() for details on how attributes are being rendered.

See also yii\helpers\Html::renderTagAttributes() for details on how attributes are being rendered.

public array $options = [
    
'class' => 'grid-view',
]
$placeFooterAfterBody public property (available since version 2.0.14)

Whether to place footer after body in DOM if $showFooter is true

$rowOptions public property

The HTML attributes for the table body rows. This can be either an array specifying the common HTML attributes for all body rows, or an anonymous function that returns an array of the HTML attributes. The anonymous function will be called once for every data model returned by $dataProvider. It should have the following signature:

function ($model, $key, $index, $grid)
  • $model: the current data model being rendered
  • $key: the key value associated with the current data model
  • $index: the zero-based index of the data model in the model array returned by $dataProvider
  • $grid: the GridView object

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\Component::__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()
{
    $this->_events = [];
    $this->_eventWildcards = [];
    $this->_behaviors = 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

{
    $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)) {

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 )

        return false;
    }

    // your custom code here

    return true; // or false to not run the widget
}
public boolean beforeRun ( )
return boolean

Defined in: yii\base\Widget::begin()

Begins a widget.

This method creates an instance of the calling class. It will apply the configuration to the created instance. A matching end() call should be called later. As some widgets may use output buffering, the end() call should be made in the same view to avoid breaking the nesting of output buffers.

See also end().

public static static begin ( $config = [] )
$config array

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

return yii\base\Widget

The newly created widget instance

                public static function begin($config = [])

    /* @var $widget Widget */
    $widget = Yii::createObject($config);

    return $widget;
}

            
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 [];
}

on() public method

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

Attaches an event handler to an event.

['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.');
});
