    public
                    __call(string $name, array<string|int, mixed> $params) : mixed

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.

Parameters

$name : string: the method name
$params : array<string|int, mixed>: method parameters

Return values

mixed —

the method return value

__clone()

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


    public
                    __clone() : mixed

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

__construct()

Constructor.


    public
                    __construct([array<string|int, mixed> $config = [] ]) : mixed

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.

Parameters

$config : array<string|int, mixed> = []: name-value pairs that will be used to initialize the object properties

__get()

Returns the value of a component property.


    public
                    __get(string $name) : mixed

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;.

Parameters

$name : string: the property name

Return values

mixed —

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

__isset()

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


    public
                    __isset(string $name) : bool

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).

Parameters

$name : string: the property name or the event name

Return values

bool —

whether the named property is set

__set()

Sets the value of a component property.


    public
                    __set(string $name, mixed $value) : mixed

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;.

Parameters

$name : string: the property name or the event name
$value : mixed: the property value

__unset()

Sets a component property to be null.


    public
                    __unset(string $name) : mixed

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).

Parameters

$name : string: the property name

addFilter()


    public
                    addFilter(string $filterKey, array<string|int, mixed> $filterData) : mixed

$filterData : array<string|int, mixed>

afterRun()

This method is invoked right after a widget is executed.


    public
                    afterRun(mixed $result) : mixed

The method will trigger the [[EVENT_AFTER_RUN]] event. The return value of the method will be used as the widget return value.

If you override this method, your code should look like the following:

public function afterRun($result)
{
    $result = parent::afterRun($result);
    // your custom code here
    return $result;
}

Parameters

$result : mixed: the widget return result.

Return values

mixed —

the processed widget result.

attachBehavior()

Attaches a behavior to this component.


    public
                    attachBehavior(string $name, string|array<string|int, mixed>|Behavior $behavior) : Behavior

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 [[Behavior::attach()]] method.

Parameters

$name : string

the name of the behavior.

$behavior : string|array<string|int, mixed>|Behavior

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

a [[Behavior]] object
a string specifying the behavior class
an object configuration array that will be passed to [[Yii::createObject()]] to create the behavior object.

Return values

Behavior —

the behavior object

attachBehaviors()

Attaches a list of behaviors to the component.


    public
                    attachBehaviors(array<string|int, mixed> $behaviors) : mixed

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

Parameters

$behaviors : array<string|int, mixed>: list of behaviors to be attached to the component

beforeRun()

This method is invoked right before the widget is executed.


    public
                    beforeRun() : bool

The method will trigger the [[EVENT_BEFORE_RUN]] event. The return value of the method will determine whether the widget should continue to run.

When overriding this method, make sure you call the parent implementation like the following:

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

    // your custom code here

    return true; // or false to not run the widget
}

Return values

bool —

whether the widget should continue to be executed.

begin()

Begins a widget.


    public
            static        begin([array<string|int, mixed> $config = [] ]) : static

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.

Parameters

$config : array<string|int, mixed> = []: name-value pairs that will be used to initialize the object properties

Return values

static —

the newly created widget instance

behaviors()

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


    public
                    behaviors() : array<string|int, mixed>

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 [[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).

Return values

array<string|int, mixed> —

the behavior configurations.

canGetProperty()
