Controller is the base class for classes containing controller logic.
For more details and usage information on Controller, see the guide article on controllers.
Property DetailsThe action that is currently being executed. This property will be set by run() when it is called by yii\base\Application to run an action.
The ID of the action that is used when the action ID is not specified in the request. Defaults to 'index'.
The ID of this controller.
The name of the layout to be applied to this controller's views. This property mainly affects the behavior of render(). Defaults to null, meaning the actual layout value should inherit that from $module's layout value. If false, no layout will be applied.
The module that this controller belongs to.
All ancestor modules that this controller is located within.
The route (module ID, controller ID and action ID) of the current request.
The controller ID that is prefixed with the module ID (if any).
The view object that can be used to render views or view files.
The directory containing the view files for this controller.
Method DetailsDefined in: yii\base\Component::__call()
Calls the named method which is not a class method.
This method will check if any attached behavior has the named method and will execute it if available.
Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.
public function __call($name, $params)
{
$this->ensureBehaviors();
foreach ($this->_behaviors as $object) {
if ($object->hasMethod($name)) {

}
}
throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()");
}
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 function __clone()
{
$this->_events = [];
$this->_eventWildcards = [];
$this->_behaviors = null;
}
public void __construct ( $id, $module, $config = [] ) $id string
The ID of this controller.
$module yii\base\ModuleThe module that this controller belongs to.
$config arrayName-value pairs that will be used to initialize the object properties.
public function __construct($id, $module, $config = [])
{
$this->id = $id;
$this->module = $module;
parent::__construct($config);
}
Defined in: yii\base\Component::__get()
Returns the value of a component property.
This method will check in the following order and act accordingly:
Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $value = $component->property;.
See also __set().
public function __get($name)
{
$getter = 'get' . $name;

}
Declares external actions for the controller.
This method is meant to be overwritten to declare external actions for the controller. It should return an array, with array keys being action IDs, and array values the corresponding action class names or action configuration arrays. For example,
return [
'action1' => 'app\components\Action1',
'action2' => [
'class' => 'app\components\Action2',
'property1' => 'value1',
'property2' => 'value2',
],
];
Yii::createObject() will be used later to create the requested action using the configuration provided here.
public function actions()
{
return [];
}
This method is invoked right after an action is executed.
The method will trigger the EVENT_AFTER_ACTION event. The return value of the method will be used as the action return value.
If you override this method, your code should look like the following:
public function afterAction($action, $result)
{
$result = parent::afterAction($action, $result);
return $result;
}
The action just executed.
$result mixedThe action return result.
return mixedThe processed action result.
public function afterAction($action, $result)
{
$event = new ActionEvent($action);
$event->result = $result;
$this->trigger(self::EVENT_AFTER_ACTION, $event);
return $event->result;
}
public function attachBehavior($name, $behavior)
{
$this->ensureBehaviors();
return $this->attachBehaviorInternal($name, $behavior);
}
public void attachBehaviors ( $behaviors ) $behaviors array
List of behaviors to be attached to the component
public function attachBehaviors($behaviors)
{
$this->ensureBehaviors();
foreach ($behaviors as $name => $behavior) {
$this->attachBehaviorInternal($name, $behavior);
}
}
This method is invoked right before an action is executed.
The method will trigger the EVENT_BEFORE_ACTION event. The return value of the method will determine whether the action should continue to run.
In case the action should not run, the request should be handled inside of the beforeAction code by either providing the necessary output or redirecting the request. Otherwise the response will be empty.
If you override this method, your code should look like the following:
public function beforeAction($action)
{
if (!parent::beforeAction($action)) {
return false;
}
return true;
}
public function beforeAction($action)
{
$event = new ActionEvent($action);
$this->trigger(self::EVENT_BEFORE_ACTION, $event);
return $event->isValid;
}
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 function behaviors()
{
return [];
}
Binds the parameters to the action.
This method is invoked by yii\base\Action when it begins to run with the given parameters.
public array bindActionParams ( $action, $params ) $action yii\base\ActionThe action to be bound with parameters.
$params arrayThe parameters to be bound to the action.
return arrayThe valid parameters that the action can run with.
public function bindActionParams($action, $params)
{

Creates an action based on the given action ID.
The method first checks if the action ID has been declared in actions(). If so, it will use the configuration declared there to create the action object. If not, it will look for a controller method whose name is in the format of actionXyz where xyz is the action ID. If found, an yii\base\InlineAction representing that method will be created and returned.

The event handler must be a valid PHP callback. The following are some examples:
function ($event) { ... }
[$object, 'handleClick']
['Page', 'handleClick']
'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.');
});
See also off().

Renders a view and applies layout if available.
The view to be rendered can be specified in one of the following formats:
To determine which layout should be applied, the following two steps are conducted:
If the layout name does not contain a file extension, it will use the default one .php.
The view name.
$params arrayThe parameters (name-value pairs) that should be made available in the view. These parameters will not be available in the layout.

}
Runs a request specified in terms of a route.
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.
See also runAction().
public mixed run ( $route, $params = [] ) $route stringThe route to be handled, e.g., 'view', 'comment/view', '/admin/comment/view'.
