是否可以在CakePHP中的app_controller.php上执行aftersave（）？

Is it possible to do an aftersave() on an app_controller.php in CakePHP?

I want to detect this on the app_controller for global use so I won't redo it on each controller or model.

Thanks, S

firstly afterSave() is function of cake's model class not controller. So recommended solution is to define a general /app/app_model.php

// app/app_model.php
class AppModel extends Model {

    function afterSave($created) {
         if($created) {
                 // do clean up after insert
         } else { 
                 // do clean up after update
         }
    }
}

In your model class

// app/models/user.php
class UserModel extends AppModel // <- its extending AppModel

This will be executed by all request by $this->ModelName->save()
