在zend框架中调用其他控制器的成员函数?
是否可以在zend框架中调用另一个控制器的成员函数，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
}
}
这是另一个控制器
<?php
class SecondController extends Zend_Controller_Action {
public indexAction() {
// here i need to call memberFunction() of FirstController
}
}
请解释我如何从第二个控制器访问 memberFunction().
Please explain how i can access memberFunction() from second controller.
更好的想法是定义一个 AppController 并使所有常用控制器扩展 AppController，从而进一步扩展 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();
}
}
现在 memberFunction 可以从扩展 AppController 的控制器调用，作为简单继承的规则.
Now memberFunction can be invoked from controllers extending AppController as a rule of simple inheritance.
推荐答案
控制器并非旨在以这种方式使用.如果您想在当前控制器之后执行另一个控制器的动作，请使用_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');
请注意，这只适用于操作方法(memberAction")，不适用于任意成员函数！
Note that this only works for action methods ("memberAction"), not arbitrary member functions!
如果 SecondController::memberFunction() 做了一些跨多个控制器需要的事情，把代码放在一个动作助手或库类中，这样两个控制器就可以访问共享的功能而不必依赖互相依赖.
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.
