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.
