本文實例講述了Zend Framework框架Smarty擴展實現方法。分享給大家供大家參考，具體如下：
今天總結一下ZF框架中擴展Smarty模板的方法，在ZF幫助文檔中已經有比較詳細的介紹，在這我稍微多說一些。
一.將smarty的核心文件包放在lib文件夾下，文件包中要包括（internals/,plugins/,Config_File.class.php,Smarty.class.php,Smarty_Compiler.class.php,debug.tpl）.
二.在Zend/View下添加文件：Smarty.php ，文件的內容如下：

三.在app文件夾下創建cache ，compile 文件夾
四.在config.ini 配置文件中加入
|
1
2
|
dir.compile = ../app/compiledir.cache = ../app/cache |
三，四兩步可以參見前面關于zendfreamwork框架搭建網站相關教程
五.在application.php 文件中添加

/*** 初始化smarty視圖**/private function _initSmartyView(){ $view = new Zend_View_Smarty(); $view->setBasePath($this->_pathConfig->dir->viewBase); $view->setScriptPath($this->_pathConfig->dir->viewBase."/scripts"); $view->setCompilePath($this->_pathConfig->dir->compile); $view->setCachePath($this->_pathConfig->dir->cache); $smarty=$view->getEngine(); $smarty->caching=false; $smarty->debugging = true; $smarty->compile_check = true; $smarty->left_delimiter = "<{"; //定義標示符 $smarty->right_delimiter = "}>"; $registry = Zend_Registry::getInstance(); $registry->set('smartyview',$smarty); //smarty對象 $registry->set('sview',$view); } |
并在 函數 init()中加入
|
1
|
$this->_initSmartyView(); |
六.在Controller中調用
因為已經將對象注冊，所以可以如下調用：
|
1
2
3
4
5
|
$view = Zend_Registry::getInstance()->get("smartyview");//注意這是smarty對象，使用smarty的那些語法，比如 $view->assign("user","root");$view = Zend_Registry::getInstance()->get("sview"); //這是zf的view對象，按zf中的那些方法用，不用改變。//按這樣，你如果要將以前寫的代碼改為用smaty，后臺不用變了，只需要將視圖文件改變就行了 |
希望本文所述對大家基于Zend Framework框架的PHP程序設計有所幫助。
