in your constructor, parent should be __construct();

Code:
parent::__construct();

Hi already change it as your suggested but i have problem in the redirect(), it will duplicate the url when i submit the form.
something like this.
[qoute]http://localhost/test/index.php/login/localhost/test/index.php/success/members_area[/qoute]

Code:
&lt;?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

 class Login extends CI_Controller{

     function index(){

       $data['maincontent'] = "login_view";

       $this->load->view("include/template",$data);

    }

    function getlogin(){

      $this->load->model('login_model');

   $query =  $this->login_model->login_check();

      if($query){

         $data = array(

             'username'=>$this->input->post('username'),

             'is_logged_in'=>true

         );

          $this->session->set_userdata($data);

          redirect('/success/members_area');

      }

   }

 }

This is my form

Code:
<div class='container'>

      &lt;form class="login" action="index.php/login/getlogin" method='post'&gt;

        <h2>Log-in</h2>

           &lt;input type='text' placeholder="username" name="username"&gt;

           &lt;input type='text' placeholder="password"  name="password"&gt;

           <button type="submit" >Log-in</button>

       &lt;/form&gt;

    </div>
