这篇文章主要介绍了Zend Framework框架Smarty扩展实现方法,结合实例形式较为详细的分析了Zend Framework框架Smarty扩展的具体步骤与相关设置技巧,需要的朋友可以参考下。
本文实例讲述了Zend Framework框架Smarty扩展实现方法,分享给大家供大家参考,具体如下:
今天总结一下ZF框架中扩展Smarty模板的方法,在ZF帮助文档中已经有比较详细的介绍,在这我稍微多说一些。
一.将smarty的核心文件包放在lib文件夹下,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 ,文件的内容如下:
- <?php
- /**
- * Zend_View_Interface
- */
- require_once 'Zend/View/Interface.php';
- /**
- * Smarty
- */
- require_once("smarty/Smarty.class.php");
- /**
- * 创建Smarty视图
- */
- class Zend_View_Smarty implements Zend_View_Interface
- {
- /**
- * Smarty object
- * @var Smarty
- */
- protected $_smarty;
- /**
- * Constructor
- *
- * @param string $tmplPath
- * @param array $extraParams
- * @return void
- */
- public function __construct($tmplPath = null, $extraParams = array())
- {
- $this->_smarty = new Smarty;
- if (null !== $tmplPath) {
- $this->setScriptPath($tmplPath);
- }
- foreach ($extraParams as $key => $value) {
- $this->_smarty->$key = $value;
- }
- }
- /**
- * Return the template engine object
- *
- * @return Smarty
- */
- public function getEngine()
- {
- return $this->_smarty;
- }
- /**
- * Set the path to the templates
- *
- * @param string $path The directory to set as the path.
- * @return void
- */
- public function setScriptPath($path)
- {
- if (is_readable($path)) {
- $this->_smarty->template_dir = $path;
- return;
- }
- throw new Exception('Invalid path provided');
- }
- /**
- * set smarty缓存
- * @author lengfeng
- */
- public function setCompilePath($path){
- if (is_readable($path)) {
- $this->_smarty->compile_dir = $path;
- return;
- }
- throw new Exception('Invalid path provided');
- }
- /**
- * set smarty 编译后文档
- * @author lengfeng
- */
- public function setCachePath($path){
- if (is_readable($path)) {
- $this->_smarty->cache_dir = $path;
- return;
- }
- throw new Exception('Invalid path provided');
- }
- /**
- * Retrieve the current template directory
- *
- * @return string
- */
- public function getScriptPaths()
- {
- return array($this->_smarty->template_dir);
- }
- /**
- * Alias for setScriptPath
- *
- * @param string $path
- * @param string $prefix Unused
- * @return void
- */
- public function setBasePath($path, $prefix = 'Zend_View')
- {
- return $this->setScriptPath($path);
- }
- /**
- * Alias for setScriptPath
- *
- * @param string $path
- * @param string $prefix Unused
- * @return void
- */
- public function addBasePath($path, $prefix = 'Zend_View')
- {
- return $this->setScriptPath($path);
- }
- /**
- * Assign a variable to the template
- *
- * @param string $key The variable name.
- * @param mixed $val The variable value.
- * @return void
- */
- public function __set($key, $val)
- {
- $this->_smarty->assign($key, $val);
- }
- /**
- * Retrieve an assigned variable
- *
- * @param string $key The variable name.
- * @return mixed The variable value.
- */
- public function __get($key)
- {
- return $this->_smarty->get_template_vars($key);
- }
- /**
- * Allows testing with empty() and isset() to work
- *
- * @param string $key
- * @return boolean
- */
- public function __isset($key)
- {
- return (null !== $this->_smarty->get_template_vars($key));
- }
- /**
- * Allows unset() on object properties to work
- *
- * @param string $key
- * @return void
- */
- public function __unset($key)
- {
- $this->_smarty->clear_assign($key);
- }
- /**
- * Assign variables to the template
- *
- * Allows setting a specific key to the specified value, OR passing an array
- * of key => value pairs to set en masse.
- *
- * @see __set()
- * @param string|array $spec The assignment strategy to use (key or array of key
- * => value pairs)
- * @param mixed $value (Optional) If assigning a named variable, use this
- * as the value.
- * @return void
- */
- public function assign($spec, $value = null)
- {
- if (is_array($spec)) {
- $this->_smarty->assign($spec);
- return;
- }
- $this->_smarty->assign($spec, $value);
- }
- /**
- * Clear all assigned variables
- *
- * Clears all variables assigned to Zend_View either via {@link assign()} or
- * property overloading ({@link __get()}/{@link __set()}).
- *
- * @return void
- */
- public function clearVars()
- {
- $this->_smarty->clear_all_assign();
- }
- /**
- * Processes a template and returns the output.
- *
- * @param string $name The template to process.
- * @return string The output.
- */
- public function render($name)
- {
- return $this->_smarty->fetch($name);
- }
- /**
- * 设置是否生成缓存
- * 如果没有参数,默认为true
- */
- public function setCache($bool){
- if (isset($bool)) {
- $this->_smarty->caching = $bool;
- return;
- }
- }
- }
三.在app文件夹下创建cache ,compile 文件夹
四.在config.ini 配置文件中加入
dir.compile = ../app/compile
dir.cache = ../app/cache
三,四两步可以参见前面关于zendfreamwork框架搭建网站相关教程
五.在application.php 文件中添加
- /**
- * 初始化smarty视图
- *
- */
- 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 = "<{"; //定义标示符
- $smarty->right_delimiter = "}>";
- $registry = Zend_Registry::getInstance();
- $registry->set('smartyview',$smarty); //smarty对象
- $registry->set('sview',$view);
- }
并在 函数 init()中加入
$this->_initSmartyView();
六.在Controller中调用
因为已经将对象注册,所以可以如下调用:
$view = Zend_Registry::getInstance()->get("smartyview");
注意这是smarty对象,使用smarty的那些语法,比如 $view->assign("user","root");
$view = Zend_Registry::getInstance()->get("sview");
这是zf的view对象,按zf中的那些方法用,不用改变。
按这样,你如果要将以前写的代码改为用smaty,后台不用变了,只需要将视图文件改变就行了
