session in codeigniter not working - php

Question

The session is not working properly. when login, it is directing member_area function which is correct but in member_area function if the condition is not working. The result is directly going in else part of member_area function that is output dies. Is there any mistake in member_area function if condition?
This is my main controller i.e., Welcome controller
function login()
{
$this->form_validation->set_rules('email', 'E-mail', 'valid_email');
$this->form_validation->set_rules('password', 'Password', 'min_length[5]|max_length[8]');
if ($this->form_validation->run()==FALSE)
{
$data['view'] = 'login_view';
$this->load->view('load_view',$data);
}
else
{
$email=$_POST['email'];
$password = md5($_POST['password']);
$this->load->model('Sample_model');
$credentials = array(
'email' => $_POST['email'],
'password' => md5($_POST['password'])
);
$user = $this->Sample_model->check_user($credentials);
if($user->num_rows() == 1)
{
$user = $user->row();
$session = array(
'name' => $user->name,
'is_logged_in' => TRUE
);
$this->session->set_userdata($sesson);
redirect('welcome/member_area');
}
else {
$data['view'] = 'error_view';
$data['msg'] = 'Login failed';
$this->load->view('load_view',$data);
}
}
}
public function member_area()
{
if($this->session->userdata('is_logged_in'))
{
$data['view'] = 'memberarea_view';
$this->load->view('load_view',$data);
}
else die('die');
}
I have added session in config/Autoload
$autoload['libraries'] = array('database','session','form_validation');
This is the model used in the present login.
Sample_model
<?php
class Sample_model extends CI_Model {
public function __construct()
{
//Call the CI_Model constructor
parent::__construct();
}
public function add_user($user)
{
return $this->db->insert('users', $user);
}
public function check_user($credentials)
{
$this->db->where($credentials);
return $this->db->get('users');
}
}
This is login_view form. I am entering email and password from this form.
