本文实例讲述了CodeIgniter集成smarty的方法。分享给大家供大家参考，具体步骤如下：
1.下载smarty
解压到ci的libraries目录 如：
ci/application/libraries/Smarty-2.6.20
2.编写Mysmarty.php 自己的类库文件
代码如下：
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');require "Smarty-2.6.20/libs/Smarty.class.php";/*** @file system/application/libraries/Mysmarty.php*/class Mysmarty extends Smarty{ function Mysmarty() { $this->Smarty(); $config =& get_config(); // absolute path prevents "template not found" errors $this->template_dir = (!empty($config['smarty_template_dir']) ? $config['smarty_template_dir'] : BASEPATH . 'application/views/'); $this->compile_dir = (!empty($config['smarty_compile_dir']) ? $config['smarty_compile_dir'] : BASEPATH . 'cache/'); //use CI's cache folder if (function_exists('site_url')) { // URL helper required $this->assign("site_url", site_url()); // so we can get the full path to CI easily } } /** * @param $resource_name string * @param $params array holds params that will be passed to the template * @desc loads the template */ function view($resource_name, $params = array()) { if (strpos($resource_name, '.') === false) { $resource_name .= '.html'; } if (is_array($params) && count($params)) { foreach ($params as $key => $value) { $this->assign($key, $value); } } // check if the template file exists. if (!is_file($this->template_dir . $resource_name)) { show_error("template: [$resource_name] cannot be found."); } return parent::display($resource_name); }} // END class smarty_library?> 3.在autoload.php让ci自动加载smarty
$autoload['libraries'] = array('database', 'mysmarty'); 或者 使用模板时再自己加载smarty
$this->load->library("mysmarty"); 4.smarty变量赋值 display模板
$this->mysmarty->assign('test', 'Hello World.');$this->mysmarty->view('smarty'); 注：images css 等外部资源文件 放在ci系统文件夹外 网站根目录下
最好用：
$this->load->helper('url'); base_url()来访问：
base_url()."images/xxx.jpg"
不要放到system里
