please me load view files layout file.

first make custom loader

<?php if ( ! defined('basepath')) exit('no direct script access allowed');   class my_loader extends ci_loader{       function __construct(){         parent::__construct();       }        function page($page, $vars=array(), $return=false){          $vars['page'] = $page;          $ci = &get_instance();          $ci->load->view('layout',$vars,$return);       }   }

save application/core/my_loader.php

now in controller load page

       $this->load->page('page_name');

in view

 <div class="container">     <?php $this->load->view($page) ?>  </div>
