CodeIgniter中使用Smarty3基本配置

<?phpif (!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" folderclass 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');    }}?>
