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.html' target='_blank'>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：* Zend_View_Interfacerequire_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/compiledir.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);
