Php 在smarty codeigniter中设置多主题配置

我已经按照本手册设置了集成smarty和codeigniter环境

http://www.coolphptools.com/codeigniter-smarty

但我想使用smarty设置多主题。我知道它必须与我的库

smarty.php

这是我的

smarty.php

文件

    <?php  if (!defined('BASEPATH')) exit('No direct script access allowed');

/**
 * Smarty Class
 *
 * @package     CodeIgniter
 * @subpackage  Libraries
 * @category    Smarty
 * @author      Kepler Gelotte
 * @link        http://www.coolphptools.com/codeigniter-smarty
 */

    function CI_Smarty()
    {
        parent::Smarty();

        $this->compile_dir = APPPATH . "views/templates_c";
        $this->template_dir = APPPATH . "views/templates";
        $this->assign( 'APPPATH', APPPATH );
        $this->assign( 'BASEPATH', BASEPATH );

问题已解决，感谢github上的某个人

https://github.com/Vheissu/Ci-Smarty

必须仔细阅读代码，因为没有关于如何实现它的文档，我花了一些时间才理解。
为什么要使用Smarty？有什么好处？我只是想学习smarty。但我不想错过MVC部分，所以我尝试了smarty和codeigniter。。为什么不使用smarty？我是第一次用它，到目前为止我很喜欢它。。使很多工作更容易，我喜欢它的模板继承。好主意。不管怎么说，我的问题解决了，看到有人贴了一个代码，就不得不检查他的代码。看到我的答案了吗
