Zend Framework 액션 어시스턴트 FlashMessenger 사용법에 대한 자세한 설명-PHP开发-php.cn

이 기사의 예에서는 Zend Framework 액션 도우미 FlashMessenger의 사용법을 설명합니다. 참고할 수 있도록 모든 사람과 공유하세요. 자세한 내용은 다음과 같습니다.

FlashMessenger는 Flash Messenger 세션을 처리하는 데 사용됩니다.

사용자가 성공적으로 등록한 후 프롬프트 페이지에 사용자 이름이 표시되어야 합니다. 요청이 get을 통해 전달되지 않으면 물론 세션을 통해 전달할 수도 있습니다.

사용자 이름을 표시합니다. 그러나 Seesion의 작업은 필연적으로 복잡합니다. Flash Messenger를 사용하면 이러한 요구 사항을 빠르게 실현할 수 있습니다.

Flash Messenger Assistant를 사용하면 사용자가 다음 요청 시 확인해야 할 메시지를 전달할 수 있습니다.

FlashMessenger는 Zend_Session_Namespace를 사용하여 향후 또는 다음 요청에 대한 메시지를 저장하지만 비교적 간단합니다.

플래시 메신저의 간단한 사용법:

helper_demo1 프로젝트 기반

/helper_demo1/application/controllers/UserController.php 추가

   
<?php
class UserController extends Zend_Controller_Action
{
  protected $_flashMessenger = null;
  public function init()
  {
    $this->_flashMessenger =
    $this->_helper->getHelper(&#39;FlashMessenger&#39;);
    $this->initView();
  }
  public function registerAction()
  {
    $this->_flashMessenger->addMessage(&#39;xxxxx,Welcome!&#39;);
    $this->_helper->redirector(&#39;regtips&#39;);
  }
  public function regtipsAction()
  {
    $this->view->messages = $this->_flashMessenger->getMessages();
  }
}
