codeigniter3整合smarty3

1. 切換到ci路徑下
   

2. 在application/libraries創建smarty文件夾，并將解壓好的Smarty庫中的libs文件夾復制到Smarty文件夾中

3. 在application/config下創建smarty.php， 代碼如下:

   <?php
   if (!defined('BASEPATH')) {
       exit('No direct script access allowed');
   }
   $config['cache_lifetime'] = 60;
   $config['caching'] = false;
   $config['template_dir'] = APPPATH . 'views/templates';
   $config['compile_dir'] = APPPATH . 'views/templates_c';
   $config['cache_dir'] = APPPATH . 'views/cache';
   $config['config_dir'] = APPPATH . 'views/config';
   $config['use_sub_dirs'] = false;
   //子目錄變量(是否在緩存文件夾中生成子目錄)
   $config['left_delimiter'] = '{';
   $config['right_delimiter'] = '}';

4. 在application/libraries下創建一個Ci_Smarty.php，代碼如下

   <?php
   if (!defined('BASEPATH')) {
       exit('No direct script access allowed');
   }
   require_once APPPATH.'libraries/smarty/libs/Smarty.class.php';
   class Ci_Smarty extends Smarty
   {
       protected $ci;
       public function __construct()
       {
           parent::__construct();
           $this -> ci =& get_instance();
           $this -> ci -> load -> config('smarty');
           //加載smarty的配置文件
           $this -> cache_lifetime = $this -> ci -> config -> item('cache_lifetime');
           $this -> caching = $this -> ci -> config -> item('caching');
           $this -> config_dir = $this -> ci -> config -> item('config_dir');
           $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('cache_dir');
           $this -> use_sub_dirs = $this -> ci -> config -> item('use_sub_dirs');
           $this -> left_delimiter = $this -> ci -> config -> item('left_delimiter');
           $this -> right_delimiter = $this -> ci -> config -> item('right_delimiter');
       }
   }

5. 打開application/config/autoload.php 修改

   $autoload['libraries'] = array('');
   改為
   $autoload['libraries'] = array('Ci_Smarty');

6. 在application/core下新建一個MY_Controller.php ，代碼如下：

   <?php
   class MY_controller extends CI_Controller
   {
       public function __construct()
       {
           parent::__construct();
       }
       public function assign($key, $val)
       {
           $this->ci_smarty->assign($key, $val);
       }
       public function display($html)
       {
           $this->ci_smarty->display($html);
       }
   }

7. 在views下創建templates目錄

8. 在templates下新建一個測試模板test.tpl

   hello.world

9. 在controllers下新建一個測試文件Pages.php繼承MY_controller

   <?php
   class Pages extends MY_controller {
       public function index()
       {
           $this->display('test.tpl');
       }
   }

10. 

11. 至此完成
