然后在global_helper中增加一个 template函数

//编译模板生成地址

$compiledtplfile = $template_cache->cache_path.DIRECTORY_SEPARATOR.'caches_template'.DIRECTORY_SEPARATOR.'default'.DIRECTORY_SEPARATOR.$module.DIRECTORY_SEPARATOR.$template.EXT;
if(!file_exists($compiledtplfile) || (file_exists($tplfile) && filemtime($tplfile) > filemtime($compiledtplfile))) {

}
}
if($return_full_path)
return $compiledtplfile;
else
return 'caches_template'.DIRECTORY_SEPARATOR.$style.DIRECTORY_SEPARATOR.$module.DIRECTORY_SEPARATOR.$template;

}然后在global_helper中增加一个 template函数if ( ! function_exists('template'))

if($return_full_path)
return $compiledtplfile;
else
return 'caches_template'.DIRECTORY_SEPARATOR.$style.DIRECTORY_SEPARATOR.$module.DIRECTORY_SEPARATOR.$template;

}
然后在MY_Controller.php
增加一个方法
/**

* @param $template
* @param $istag
* @return unknown_type
*/
protected function view($view_file,$page_data=false,$cache=false)

$this->load->view($view_file,$page_data);
