复制代码 然后在global_helper中增加一个 template函数- if ( ! function_exists('template'))

复制代码
然后在MY_Controller.php
增加一个方法
- /**

- *
- * @param $module
- * @param $template
- * @param $istag
- * @return unknown_type
- */
- protected function view($view_file,$page_data=false,$cache=false)
- {
- $view_file=$this->template($this->page_data['controller_name'].$this->page_data['module_name'],$view_file);
-
- $this->load->view($view_file,$page_data);
- }
