這篇文章將為大家詳細(xì)講解有關(guān)如何在Zend Framework框架中安裝Smarty擴(kuò)展,文章內(nèi)容質(zhì)量較高,因此小編分享給大家做個參考,希望大家閱讀完這篇文章后對相關(guān)知識有一定的了解。
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(nèi)容如下:
<?php /** * Zend_View_Interface */ require_once 'Zend/View/Interface.php'; /** * Smarty */ require_once("smarty/Smarty.class.php"); /** * 創(chuàng)建Smarty視圖 */ 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 = $path; return; } throw new Exception('Invalid path provided'); } /** * set smarty緩存 * @author lengfeng */ public function setCompilePath($path){ if (is_readable($path)) { $this->_smarty->compile_dir = $path; return; } throw new Exception('Invalid path provided'); } /** * set smarty 編譯后文檔 * @author lengfeng */ public function setCachePath($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); } /** * 設(shè)置是否生成緩存 * 如果沒有參數(shù),默認(rèn)為true */ public function setCache($bool){ if (isset($bool)) { $this->_smarty->caching = $bool; return; } } }
三.在app文件夾下創(chuàng)建cache ,compile 文件夾
四.在config.ini 配置文件中加入
dir.compile = ../app/compile dir.cache = ../app/cache
三,四兩步可以參見前面關(guān)于zendfreamwork框架搭建網(wǎng)站相關(guān)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(biāo)示符 $smarty->right_delimiter = "}>"; $registry = Zend_Registry::getInstance(); $registry->set('smartyview',$smarty); //smarty對象 $registry->set('sview',$view); }
并在 函數(shù) init()中加入
$this->_initSmartyView();
六.在Controller中調(diào)用
因?yàn)橐呀?jīng)將對象注冊,所以可以如下調(diào)用:
$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
