CakePHP共享控制器视图/功能

Question

I don't know how to do this:

I have a CakePHP project that uses AdministratorsController and UsersController for different roles, etc.. but, a User can save a Message and a Administrator too! So, should I repeat the same function or what?

function saveMessage(){
    $this->autoRender = false;
    if (!$this->RequestHandler->isPost())
        $this->Session->setFlash('Error 78.', 'flash_custom_danger');
    else{   
        if(!$this->Message->save($this->request->data))
            $this->Session->setFlash('Error 985.', 'flash_custom_success');
        else
            $this->Session->setFlash('Success!', 'flash_custom_success');       

    }
    $this->redirect('/');
}

Move the function to app_controller, because both your controllers will extend from it.

In the app_controller:

function my_function($controller_specific_string = null){ 
    //stuff here common to both controllers
}

In the controller(s):

function my_function() { //extended function in both controllers
  // do controller specific stuff here...

  return parent::my_function('from_users_controller');
}
