   $this->form_validation->set_rules('email', 'Email', 'required|valid_email');
   $this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean|callback_check_database');

   //Field validation succeeded.  Validate against database
   $email = $this->input->post('email');

   //query the database
   $result = $this->user_model->login($email, $password);

   if($result)
   {
     $sess_array = array();
     foreach($result as $row)
     {
       $sess_array = array(
         'user_id' => $row->user_id,
         'email' => $row->email
       );
        // $session_data = $this->session->set_userdata('logged_in',$sess_array);
        $this->session->set_userdata('logged_in', $sess_array);

     }
     return TRUE;
   }

   else

     $this->form_validation->set_message('check_database', 'Invalid email or password');
     return false;
   }
 }
}

Home Controller

    <?php 

session_start(); //we need to call PHP's session object to access it through CI
class Home extends CI_Controller {

 function __construct()
 {
   parent::__construct();
 }

 function index()
 {
   if($this->session->userdata('logged_in'))
   {
     $session_data = $this->session->userdata('logged_in');
     $data['email'] = $session_data['email'];
     $this->load->view('home', $data);
   }
   else
   {
     //If no session, redirect to login page
     redirect('login', 'refresh');
   }
 }

 function logout()
 {
   $this->session->unset_userdata('logged_in');
   session_destroy();
   redirect('home', 'refresh');
 }

User model

    <?php

if (!defined('BASEPATH')) exit('No direct script access allowed');

class User_model extends CI_Model {

    public function login($email, $password){

        $this->db->select('user_id','email','password');
        $this->db->from('users');
        $this->db->where('email',$email);
        $this->db->where('password',md5($password));
        $this->db->limit(1);

        $query = $this->db->get();

        if($query->num_rows() == 1){

            return $query->result();
        }
        else {

            return false;
        }
    }
    public function register($name, $surname, $email, $password)
    {
        $data = array(
          'name' => $name,
          'surname' => $surname,
          'email' => $email,
          'password' => md5($password)
            );

        if( ($name && $surname && $email && $password) != NULL){
          $query = $this->db->insert('users', $data);

        }
        else{
          return false;
        }

The Solution: user_model.php

This

$query = $this->db->select('user_id','email','password')

Change to $query = $this->db->select('user_id,email','password')

MY GOD!

I think there is problem in your form_open() method

<?php echo form_open('verifylogin'); ?>

You get your variable in controller VerifyLogin of function check_database()

So you form_open would be

<?php echo form_open('verifylogin/check_database'); ?>

and you forget to load 

$this->load->helper('form');

try to read manual CI form helper
