CodeIgniter中使用Smarty3基本配置

<?php
if (!defined('BASEPATH')) exit('No direct script access allowed');
require(APPPATH . 'libraries/smarty/Smarty.class.php');
//CI，文件系统全用相对路径相对index.php所在的路径，url全部用绝对路径。
//BASEPATH    - The full server path to the "system" folder
//APPPATH    - The full server path to the "application" folder
class Cismarty extends Smarty
{
  public function __construct()
  {
 
    parent::__construct();
    $this->caching = false;
    $this->setTemplateDir(APPPATH . 'views/Smarty/templates'); //设定所有模板文件都需要放置的目录地址。
    $this->setConfigDir(APPPATH . 'views/Smarty/configs'); //设定用于存放模板特殊配置文件的目录，
    $this->setCacheDir(APPPATH . 'views/Smarty/cache'); //在启动缓存特性的情况下，这个属性所指定的目录中放置Smarty缓存的所有模板
    $this->setPluginsDir(APPPATH . 'views/Smarty/plugins'); //插件目录
    $this->setCompileDir(APPPATH . 'views/Smarty/templates_c'); //设定Smarty编译过的所有模板文件的存放目录地址
 
 
  }
 
}
 
?>

<?php
 
class Paper extends CI_Controller
{
  function __construct()
  {
    parent::__construct();
  }
 
  public function pri_body()
  {
 
    $this->load->library('cismarty');
    $this->cismarty->assign("name", 1200);
    $this->cismarty->display('dd.tpl');
 
 
  }
}
?>
