Source Code https://github.com/yiisoft/yii2/blob/master/framework/grid/CheckboxColumn.php

CheckboxColumn displays a column of checkboxes in a grid view.

To add a CheckboxColumn to the yii\grid\GridView, add it to the columns configuration as follows:

'columns' => [
    // ...
    [
        'class' => 'yii\grid\CheckboxColumn',
        // you may configure additional properties here
    ],
]

Users may click on the checkboxes to select rows of the grid. The selected rows may be obtained by calling the following JavaScript code:

var keys = $('#grid').yiiGridView('getSelectedRows');
// keys is an array consisting of the keys associated with the selected rows

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

Property Details

$checkboxOptions public property

The HTML attributes for checkboxes. This can either be an array of attributes or an anonymous function (Closure) that returns such an array. The signature of the function should be the following: function ($model, $key, $index, $column). Where $model, $key, and $index refer to the model, key and index of the row currently being rendered and $column is a reference to the yii\grid\CheckboxColumn object. A function may be used to assign different attributes to different rows based on the data in that row. Specifically if you want to set a different value for the checkbox you can use this option in the following way (in this example using the name attribute of the model):

'checkboxOptions' => function ($model, $key, $index, $column) {
    return ['value' => $model->name];
}

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

public array|Closure $checkboxOptions = []
$cssClass public property (available since version 2.0.9)

The css class that will be used to find the checkboxes.

public string $cssClass = null
$multiple public property

Whether it is possible to select multiple rows. Defaults to true.

public boolean $multiple = true
$name public property

The name of the input checkbox input fields. This will be appended with [] to ensure it is an array.

public string $name = 'selection'

Method Details

__call() public method

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

Calls the named method which is not a class method.

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, $params)
{
    throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()");
}
__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\BaseObject::__get()

Returns the value of an object property.

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

See also __set().

public mixed __get ( $name )
$name string

The property name
return mixed

The property value
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)) {
        return $this->$getter();
    } elseif (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\BaseObject::__isset()

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

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

Note that if the property is not defined, false will be returned.

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 (not null).

 

                public function __isset($name)
{
    $getter = 'get' . $name;
    if (method_exists($this, $getter)) {
        return $this->$getter() !== null;
    }
    return false;
}
__set() public method

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

Sets value of an object property.

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

See also __get().

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

The property name or the event name
$value mixed

The property value

{
    $setter = 'set' . $name;
    if (method_exists($this, $setter)) {
        $this->$setter($value);
    } elseif (method_exists($this, 'get' . $name)) {
        throw new InvalidCallException('Setting read-only property: ' . get_class($this) . '::' . $name);

    }
}
__unset() public method

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

Sets an object property to null.
