EControllerBehavior is a behavior that can handle controller events:

• beforeAction
• afterAction
• beforeRender
• afterRender

Your controller should extend EController. You create a behavior by extending EControllerBehavior and implement one of above listed methods. Inside a handler you have $event instance, which has following properties:

• in beforeRender: $event->view.
• in afterRender: $event->view and $event->output.
• in beforeAction: $event->action.
• in afterAction: $event->action.

Also, in beforeAction and beforeRender you can set $event->isValid property to allow or deny corresponding processing.

Also, it supports actions inside behaviors.

Example

// main.php
	'import' => array('ext.controller-events.*'),
// CrudController.php
<?php
class CrudController extends EControllerBehavior {
	public function beforeAction(EControllerEvent $event) {
		if (rand(0, 1))
			$event->isValid = false;
	}
}
