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

_flashMessenger = $this->_helper->getHelper; $this->initView(); } public function registerAction() { $this->_flashMessenger->addMessage; $this->_helper->redirector; } public function regtipsAction() { $this->view->messages = $this->_flashMessenger->getMessages(); }}

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

test

FlashMessager实现源码如下

 $messages) { self::$_messages[$namespace] = $messages; unset(self::$_session->{$namespace}); } } } /** * postDispatch() - runs after action is dispatched, in this * case, it is resetting the namespace in case we have forwarded to a different * action, Flashmessage will be 'clean'  * * @return Zend_Controller_Action_Helper_FlashMessenger Provides a fluent interface */ public function postDispatch() { $this->resetNamespace(); return $this; } /** * setNamespace() - change the namespace messages are added to, useful for * per action controller messaging between requests * * @param string $namespace * @return Zend_Controller_Action_Helper_FlashMessenger Provides a fluent interface */ public function setNamespace($namespace = 'default') { $this->_namespace = $namespace; return $this; } /** * resetNamespace() - reset the namespace to the default * * @return Zend_Controller_Action_Helper_FlashMessenger Provides a fluent interface */ public function resetNamespace() { $this->setNamespace(); return $this; } /** * addMessage() - Add a message to flash message * * @param string $message * @return Zend_Controller_Action_Helper_FlashMessenger Provides a fluent interface */ public function addMessage { if (self::$_messageAdded === false) { self::$_session->setExpirationHops; } if (!is_array(self::$_session->{$this->_namespace})) { self::$_session->{$this->_namespace} = array(); } self::$_session->{$this->_namespace}[] = $message; return $this; } /** * hasMessages() - Wether a specific namespace has messages * * @return boolean */ public function hasMessages() { return isset(self::$_messages[$this->_namespace]); } /** * getMessages() - Get messages from a specific namespace * * @return array */ public function getMessages() { if  { return self::$_messages[$this->_namespace]; } return array(); } /** * Clear all messages from the previous request & current namespace * * @return boolean True if messages were cleared, false if none existed */ public function clearMessages() { if  { unset(self::$_messages[$this->_namespace]); return true; } return false; } /** * hasCurrentMessages() - check to see if messages have been added to current * namespace within this request * * @return boolean */ public function hasCurrentMessages() { return isset(self::$_session->{$this->_namespace}); } /** * getCurrentMessages() - get messages that have been added to the current * namespace within this request * * @return array */ public function getCurrentMessages() { if ($this->hasCurrentMessages { return self::$_session->{$this->_namespace}; } return array(); } /** * clear messages from the current request & current namespace * * @return boolean */ public function clearCurrentMessages() { if ($this->hasCurrentMessages { unset(self::$_session->{$this->_namespace}); return true; } return false; } /** * getIterator() - complete the IteratorAggregate interface, for iterating * * @return ArrayObject */ public function getIterator() { if  { return new ArrayObject; } return new ArrayObject - Complete the countable interface * * @return int */ public function count() { if  { return count; } return 0; } /** * Strategy pattern: proxy to addMessage() * * @param string $message * @return void */ public function direct { return $this->addMessage; }}
