Zend Framework动作助手FlashMessenger用法详解

Posted in PHP onMarch 05, 2016

本文实例讲述了Zend Framework动作助手FlashMessenger用法。分享给大家供大家参考，具体如下：

FlashMessenger 用来处理Flash Messenger会话；FlashMessenger是一个神奇的助手。

有这么一种场景，在用户注册成功后，需要在提示页面上显示用户的名称，如果不通过get传递请求，当然你也可以通过session传递

要显示的用户名称。但是seesion的操作难免复杂，可以使用Flash Messenger快速的实现这个需求。

FlashMessenger助手允许你传递用户可能需要在下个请求看到的消息。

FlashMessenger也是使用Zend_Session_Namespace来存储消息以备将来或下个请求来读取，但是相对简单一些。

FlashMessenger简单用法：

在helper_demo1项目的基础上

新增/helper_demo1/application/controllers/UserController.php

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

新增/helper_demo1/application/views/scripts/user/regtips.phtml

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>test</title>
</head>
<body>
<?php
var_dump($this->messages);
?>
</body>
</html>
