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

beforeAction()

This method is invoked right before an action is executed.


    public
                    beforeAction(mixed $action) : bool

Parameters

$action : mixed: the action to be executed.

Return values

bool —

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.

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 [[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.');
});

Parameters

$name : string: the event name
$handler : callable: the event handler
$data : mixed = null: the data to be passed to the event handler when the event is triggered. When the event handler is invoked, this data can be accessed via [[Event::data]].

An example of how to use the prompt method with a validator function.

$code = $this->prompt('Enter 4-Chars-Pin', ['required' => true, 'validator' => function($input, &$error) {
    if (strlen($input) !== 4) {
        $error = 'The Pin must be exactly 4 chars!';

render()

Renders a view and applies layout if available.


    public
                    render(string $view[, array<string|int, mixed> $params = [] ]) : string

The view to be rendered can be specified in one of the following formats:

path alias (e.g. "@app/views/site/index");
absolute path within application (e.g. "//site/index"): the view name starts with double slashes. The actual view file will be looked for under the [[Application::viewPath|view path]] of the application.
absolute path within module (e.g. "/site/index"): the view name starts with a single slash. The actual view file will be looked for under the [[Module::viewPath|view path]] of [[module]].
relative path (e.g. "index"): the actual view file will be looked for under [[viewPath]].

To determine which layout should be applied, the following two steps are conducted:

In the first step, it determines the layout name and the context module:

If [[layout]] is specified as a string, use it as the layout name and [[module]] as the context module;
If [[layout]] is null, search through all ancestor modules of this controller and find the first module whose [[Module::layout|layout]] is not null. The layout and the corresponding module are used as the layout name and the context module, respectively. If such a module is not found or the corresponding layout is not a string, it will return false, meaning no applicable layout.

In the second step, it determines the actual layout file according to the previously found layout name and context module. The layout name can be:

a path alias (e.g. "@app/views/layouts/main");
an absolute path (e.g. "/main"): the layout name starts with a slash. The actual layout file will be looked for under the [[Application::layoutPath|layout path]] of the application;
a relative path (e.g. "main"): the actual layout file will be looked for under the [[Module::layoutPath|layout path]] of the context module.

If the layout name does not contain a file extension, it will use the default one .php.

Parameters

$view : string: the view name.
$params : array<string|int, mixed> = []: the parameters (name-value pairs) that should be made available in the view. These parameters will not be available in the layout.

Return values

string —

the rendering result.

renderContent()

Renders a static string by applying a layout.


    public
                    renderContent(string $content) : string

Parameters

$content : string: the static string being rendered

Return values

string —

the rendering result of the layout with the given static string as the $content variable. If the layout is disabled, the string will be returned back.

    public
                    renderFile(string $file[, array<string|int, mixed> $params = [] ]) : string

the rendering result.

renderPartial()

Renders a view without applying layout.


    public
                    renderPartial(string $view[, array<string|int, mixed> $params = [] ]) : string

This method differs from [[render()]] in that it does not apply any layout.

Parameters

If the route starts with a slash '/', the parsing of the route will start from the application; otherwise, it will start from the parent module of this controller.

Parameters

$route : string: the route to be handled, e.g., 'view', 'comment/view', '/admin/comment/view'.
$params : array<string|int, mixed> = []: the parameters to be passed to the action.
