the login seems work , redirects members area when check ci_session table it's empty.

once in members area want logout should destroy current session , redirect index.php home page doesn't do.

here members v\c

controller member area

<?php defined('basepath') or exit('no direct script access allowed');  class members_area extends ci_controller {      public function __construct()      {           parent::__construct();           $this->loginuser();      }      public function index()     {           $data['title'] = "";         $data['description'] = "";         $data['keywords'] = "";         $data['type'] = "";         $data['url'] = "";          $this->load->view('includes/member_header' , $data);         $this->load->view('members/members-area');         $this->load->view('includes/footer');      }      function loginuser()     {         $loginuser = $this->session->userdata('loginuser');          if (!isset($loginuser) || $loginuser != true )          {             echo 'sorry dont have premission access area. please signup , login gain access area.';             die();         }     } }

any advice or direction folks huge help.

thanks!

in config.php file need enable ci session:

$config['sess_use_database'] = true; 

from ci user guide:

once enabled, session class store session data in db.

make sure you've specified table name in config file well:

$config['sess_table_name'] = 'ci_sessions'; 

you can change name per table name.
