1，将 Smarty 文件中的 lib 文件夹   拷贝至 CodeIgniterh目录 application\libraries 文件夹下 并重命名smarty lib文件名

2，在application\libraries目录中新建文件：，并拷贝如下内容

<?php if(!defined('BASEPATH'))exit('no dir'); require_once (APPPATH.'libraries/Cismarty/Smarty.class.php');class Cismarty extends Smarty {protected $ci;function __construct(){parent::__construct();$this->ci = &get_instance();$this->template_dir = $this->ci->config->item('template_dir');$this->compile_dir = $this->ci->config->item('compile_dir');$this->cache_dir = $this->ci->config->item('caching_dir');$this->config_dir = $this->ci->config->item('config_dir');//$this->template_ext = $this->ci->config->item('template_ext');$this->caching = $this->ci->config->item('caching');$this->cache_lifetime = $this->ci->config->item('cache_lifetime');$this->left_delimiter = $this->ci->config->item('left_delimiter');$this->right_delimiter = $this->ci->config->item('right_delimiter');}}
?>

3，在application\config目录中新建，并拷贝如下内容作为配置文件

<?php if (! defined('BASEPATH')) exit('no direct base');
//    $config['template_dir'] = APPPATH.'views';
//    $config['compile_dir']     = FCPATH.'template_c';
//    $config['caching_dir']     = FCPATH.'cache';
//    $config['config_dir']     = FCPATH.'config';$config['template_dir'] = APPPATH.'views/templates';$config['compile_dir']     = APPPATH.'views/template_c';$config['caching_dir']     = FCPATH.'cache';$config['config_dir']     = FCPATH.'config';$config['caching']         = false;            //是否开启缓存$config['cache_lifetime']     = '60';            //缓存生存时间（秒）//$config['template_ext']     = '.html';$config['left_delimiter']     = '{!~';$config['right_delimiter']     = '~!}';?>

4，打开application\config文件，设置自动加载smarty配置文件和加载smarty插件，增加或修改如下内容

$autoload['config'] = array('smarty');         //自动加载配置文件
$autoload['libraries'] = array('cismarty');    //自动每一页加载smarty模板

ps.如果不自动加载时可以在需要使用的页面中调用 $this->load->library('cismarty');进行加载

5，测试程序

a,在application\controllers目录中新建立控制器  内容如下：

<?php
class Test extends CI_Controller {function __construct(){parent::__construct();//$this->load->library("cismarty");$this->load->library('form_validation');$this->form_validation->set_error_delimiters('<p class="error">', '</p>');}public function index(){$this->cismarty->assign("Name","test name");$this->cismarty->display( 'test.html' );}
}
?>

b,在application\views\templates模板目录中新建模板文件内容如下：

{!~$Name~!}

c,输入 http://localhost/you项目部/index.php/test  测试效果
