在 CodeIgniter 2中集成 Smarty 3 模板引擎

下载CodeIgniter并解压，然后部署服务器（例如使用Apache，可自行添加vhost，设定路径和端口号）。

CI2下载地址：http://ellislab.com/codeigniter

下载Smarty3：http://www.smarty.net/download

解压后，修改最外层根目录文件夹名称为smarty, 然后拷贝挣个smarty文件夹到CI的application/libraries/文件夹下。

在CI的application/libraries/文件夹下（此时这个文件夹下应该还有刚拷贝进来的smarty程序），新建smarty.php文件，内容如下：

<?phpif ( ! defined('BASEPATH')) exit('No direct script access allowed');require_once(APPPATH.'libraries/smarty/libs/Smarty.class.php');class CI_Smarty extends Smarty {function __construct(){parent::__construct();$this->setTemplateDir(APPPATH.'views');$this->setCompileDir(APPPATH.'views/compiled');$this->setConfigDir(APPPATH.'libraries/smarty/configs');$this->setCacheDir(APPPATH.'libraries/smarty/cache');$this->assign('APPPATH', APPPATH);$this->assign('BASEPATH', BASEPATH);if ( method_exists($this, 'assignByRef')) {$ci =& get_instance();$this->assignByRef("ci", $ci);}$this->force_compile = 1;$this->caching = true;$this->cache_lifetime = 120;}function view($template_name) {if (strpos($template_name, '.') === FALSE && strpos($template_name, ':') === FALSE) {$template_name .= '.php';}parent::display($template_name);}}

修改application/config/目录下的autoload.php文件，在$autoload['libraries']里添加smarty，例如：

$autoload['libraries'] = array('smarty', 'database');

测试：

新建controller文件test.php：

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');class Test extends CI_Controller {public function index() {$this->smarty->assign("title","Testing Smarty");$this->smarty->assign("description", "This is the testing page for integrating Smarty and CodeIgniter.");$this->smarty->view('test');}}

还有view文件：test.php

<p>test.php page shows the variables here:</p><p>title: {$title}</p><p>description: {$description}</p>

注意，需要在CI的application/views/目录下新建compiled文件夹(因为在上面的smarty.php中已经设定了将在views/compiled下存在smarty编译后的php文件)

这样通过URL正常访问这个test controller应该能看这个通过smarty模板技术生成的view了。
