問題描述

是否可以在zend框架中調用另一個控制器的成員函數，如果是，那么如何?

Is it possible to call the member function of another controller in zend framework, if yes then how?

<?php
class FirstController extends Zend_Controller_Action {
    public function indexAction() {
         // general action 
    }   

    public function memberFunction() {
         // a resuable function
    }
}

這是另一個控制器

<?php
class SecondController extends Zend_Controller_Action {
    public indexAction() {
         // here i need to call memberFunction() of FirstController
    }
}

請解釋我如何從第二個控制器訪問 memberFunction().

Please explain how i can access memberFunction() from second controller.

更好的想法是定義一個 AppController 并使所有常用控制器擴展 AppController，從而進一步擴展 Zend_Controller_Action.

Better idea is to define a AppController and make all usual controllers to extend AppController which further extends Zend_Controller_Action.

class AppController extends Zend_Controller_Action {
    public function memberFunction() {
         // a resuable function
    }
}

class FirstController extends AppController {
    public function indexAction() {
         // call function from any child class
         $this->memberFunction();
    } 
}

現在 memberFunction 可以從擴展 AppController 的控制器調用，作為簡單繼承的規則.

Now memberFunction can be invoked from controllers extending AppController as a rule of simple inheritance.

推薦答案

控制器并非旨在以這種方式使用.如果您想在當前控制器之后執行另一個控制器的動作，請使用_forward()方法:

Controllers aren't designed to be used in that way. If you want to execute an action of the other controller after your current controller, use the _forward() method:

// Invokes SecondController::otherActionAction() after the current action has been finished.
$this->_forward('other-action', 'second');

請注意，這只適用于操作方法(memberAction")，不適用于任意成員函數！

Note that this only works for action methods ("memberAction"), not arbitrary member functions!

如果 SecondController::memberFunction() 做了一些跨多個控制器需要的事情，把代碼放在一個動作助手或庫類中，這樣兩個控制器就可以訪問共享的功能而不必依賴互相依賴.

If SecondController::memberFunction() does something that is needed across multiple controllers, put that code in a action helper or library class, so that both controllers can access the shared functionality without having to depend on each other.
