what must problem code:

<!doctype html> <html>     <head>         <meta http-equiv="content-type" content="text/html; charset=utf-8">         <title><?php echo $title; ?></title>         <?php              echo link_tag('assets/css/jquery.mobile-1.3.2.min.css', 'stylesheet');             echo script_tag('assets/js/jquery-1.10.2.min.js');              echo script_tag('assets/js/jquery.mobile-1.3.2.min.js');          ?>     </head>     <body>         <div data-role="page">             <header data-role="header">             <a href="#navigation" data-role="button">show</a>             <h3><?php echo $title; ?></h3>             <div data-role="controlgroup" data-type="horizontal" class="ui-btn-right">                 <a href="#" data-role="button">my account</a>                 <a href="<?php echo site_url();?>login" data-role="button">logout</a>                               </div>               </header>

i'am using jquery mobile client-side script , php(codeigniter) server-side script. when refresh page after including in anchor page doesn't display page anymore.

can tell what's wrong code or i'am missing something. 

<?php if ( ! defined('basepath')) exit('no direct script access allowed');     class event_management_c extends ci_controller {         public function __construct() {              parent::__construct();              $this->load->helper('html', 'url', 'form');         }          public function index() {             $data['title'] = 'events';             $data['reply_title'] = 'reply message';              $this->load->view('fragments/header', $data);             $this->load->view('fragments/nav', $data);             $this->load->view('events/index', $data);             $this->load->view('fragments/footer', $data);         }      }     ?>

based on answers comments; problem function site_url() isn't defined. result of fatal error, isn't shown due settings in php concerning error_report.

to solve this, run $this->load->helper('url') in relevant controller, or add url helper array in application/config/autoload.php. since function common, recommend autoload it.
