PHP Class yii\base\Action

Action provides a way to reuse action method code. An action method in an Action class can be used in multiple controllers or in different projects. Derived classes must implement a method named run(). This method will be invoked by the controller when the action is requested. The run() method can have parameters which will be filled up with user input values automatically according to their names. For example, if the run() method is declared as follows: php public function run($id, $type = 'book') { ... } And the parameters provided for the action are: ['id' => 1]. Then the run() method will be invoked as run(1) automatically. For more details and usage information on Action, see the guide article on actions.
