首先复制一份smarty源文件到application/libraries目录下。 自定义smarty配置文件方便修改：config/cismarty.php

---

// The name of the directory where templates are located.
$config['template_dir'] = APPPATH . 'views/';

// The directory where compiled templates are located
//注意这里要手动建立文件
$config['compile_dir'] = APPPATH . 'cache/compile/';

//This tells Smarty whether or not to cache the output of the templates to the $cache_dir.
$config['caching'] = 0;

// This forces Smarty to (re)compile templates on every invocation. When deploying, change this value to 0
$config['force_compile'] = 1;
$config['compile_check'] = TRUE;

// The delimiter for smarty
$config['left_delimiter'] = '{%';
$config['right_delimiter'] = '%}';

以上都是smarty一些常量 然后创建类 application/libraries/CI_smarty.php

---

<?php

require_once(APPPATH.'libraries/smarty/Smarty.class.php');

class CI_smarty extends Smarty{

    private $config;

    function CI_smarty(){

        parent::Smarty();
        require_once(APPPATH.'config/cismarty.php');
        $this->config = $config;//$config 是cismarty.php中数组变量名
        if(count($this->config)>0)
        {
            $this->initialize($this->config);
        }
    }
    /**
	 * Initialize preferences
	 */
	function initialize($config = array()) {
		foreach ($config as $key => $val) {
			if (isset($this->$key)) {
                                //这里是根据自己需要扩展一些set方法
				$method = 'set_'.$key;

				if (method_exists($this, $method)) {
					$this->$method($val);
				} else {
                                //修改smarty源文件默认变量，这里是自定义cismarty数组值
					$this->$key = $val;
				}
			}
		}
	}
}
?>

---

然后在application/config/autoload.php 找$autoload[’libraries’] = array(’CI_smarty’); CI_smarty对应上面类。

测试： 控制器中使用

        $val = 'This is ci_smarty test';
        $this->ci_smarty->assign_by_ref('val',$val);
        $this->ci_smarty->display('test.html');
