    '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.

off()

Detaches an existing event handler from this component.


    public
                    off(string $name[, callable|null $handler = null ]) : bool

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.

Parameters

$name : string: event name
$handler : callable|null = null: the event handler to be removed. If it is null, all handlers attached to the named event will be removed.

Return values

bool —

if a handler is found and detached

on()

Attaches an event handler to an event.


    public
                    on(string $name, callable $handler[, mixed $data = null ][, bool $append = true ]) : mixed

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 [[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]].
$append : bool = true: whether to append new event handler to the end of the existing handler list. If false, the new handler will be inserted at the beginning of the existing handler list.

optionAliases()

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

Child classes may override this method to specify alias options.

Return values

array<string|int, mixed> —

options()

Returns the names of valid options for the action (id) An option requires the existence of a public member variable whose name is the option name.


    public
                    options(mixed $id) : array<string|int, string>

Parameters

$id : mixed

prompt string

$options : array<string|int, mixed> = []

the options to validate the input:

required: whether it is required or not
default: default value if no input is inserted by the user
pattern: regular expression pattern to validate user input
validator: a callable function to validate input. The function must accept two parameters:
- $input: the user input to validate
- $error: the error value passed by reference if validation failed.

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!';
        return false;
    }
    return true;
}]);

Return values

string —

the user input

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.

renderFile()

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

Parameters

$file : string: the view file to be rendered. This can be either a file path or a path alias.
$params : array<string|int, mixed> = []: the parameters (name-value pairs) that should be made available in the view.

Return values

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

$view : string: the view name. Please refer to [[render()]] on how to specify a view name.
$params : array<string|int, mixed> = []: the parameters (name-value pairs) that should be made available in the view.

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

The route can be either an ID of an action within this controller or a complete route consisting of module IDs, controller ID and action ID. 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.

Return values

mixed —

the result of the action.

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

If the action ID is empty, the method will use [[defaultAction]].

Parameters

$id : string: the ID of the action to be executed.
$params : array<string|int, mixed> = []: the parameters (name-value pairs) to be passed to the action.

Return values

int —

the status of the action execution. 0 means normal, other values mean abnormal.
