php - 如何扩展Zend_Controller_Action以使函数在所有 Controller 中通用

我想扩展zend_controller_操作，这样我就可以让消息具有通用性。现在在predispatch（）中，我正在设置所有的错误和警告消息。如何使addMessage（参见代码）和predispatch函数在所有控制器中通用？

<?php

类playgroundcontroller扩展zend_controller_操作
{

public function init()
{
    /* Initialize action controller here */
}

public function preDispatch()
{
    $flashMessenger = $this->_helper->FlashMessenger;

    $flashMessenger->setNamespace('Errors');
    $this->view->Errors = $flashMessenger->getMessages();

    $flashMessenger->setNamespace('Warnings');
    $this->view->Warnings = $flashMessenger->getMessages();

    $flashMessenger->setNamespace('Messages');
    $this->view->Messages = $flashMessenger->getMessages();

    $flashMessenger->setNamespace('Success');
    $this->view->Success = $flashMessenger->getMessages();

}

protected function AddMessage($message,$type='Errors') {
    $flashMessenger = $this->_helper->FlashMessenger;
    $flashMessenger->setNamespace($type);
    $flashMessenger->addMessage($message);
}

public function flashAction()
{
    $this->AddMessage('This is an error message');
    $this->AddMessage('This is another error message');
    $this->AddMessage('This is a warning message','Warnings');
    $this->AddMessage('This is message','Messages');
    $this->AddMessage('This is another success message','Success');
}

}

最佳答案

我没有任何采埃孚的经验，但我无法想象为什么以下这些都不起作用：

abstract class Zend_Controller_MyAction extends Zend_Controller_Action
{
  public function preDispatch()
  {
  ...
  }

  protected function addMessage ($message, $type='Errors')
  {
    ....
  }
  //... other common methods
}

然后您的PlaygroundController将扩展Zend_Controller_MyAction而不是Zend_Controller_Action。
