Yii Action Method Tips

Action is defined as a method named with the word action as the prefix. A more advanced way is to define an action class and have the controller instantiate it when it receives a request. This allows actions to be reused, improving reusability.

1. Define an action class. The basic format is as follows:

class UpdateAction extends CAction{
	public function run(){
		//...逻辑代码...
	}
}

2. Use the action class: In order to let the controller notice this action, we need to override the actions() method of the controller class in the following way:

class PostController extends CController{
	public function actions(){
		return array(
		//使用"应用程序文件夹/controllers/post/UpdateAction.php" 文件中的类来处理edit动作
			'edit'=>'application.controllers.post.UpdateAction',
		);
	}
}

As shown above, we used the path alias application.controllers.post.UpdateAction to specify the action class file as protected/controllers/post/UpdateAction.php

By writing class-based actions, we can organize the application into a module style.
