login.php

<?php
class Login extends MY_Controller
{
public function index()
{
$this->load->view('login_view');
}
public function user_login()
{

$this->form_validation->set_error_delimiters('<p class="text-danger">','</p>');
if($this->form_validation->run('login_rules'))
{
$email = $this->input->post('uemail');
$password = $this->input->post('upassword');

$this->load->model('loginmodel');
$login_id = $this->loginmodel->login_valid($email, $password);
if($login_id)
{
$this->session->set_userdata('user_id', $login_id);

return redirect('admin/dashboard');

echo "password do not match.";

propertymodel.php
<?php 
class Propertymodel extends CI_Model
{
public function property_list()
{
$user_id = $this->session->userdata('user_id');
$query = $this->db
->select('prop_name')
->from('properties')
->where('user_id', $user_id )
->get();

Simpler is always better

If you read the CodeIgniter Users Guide on Session Library you would have found your answer.

If you read the CodeIgniter Users Guide on Session Library you would have found your answer.

I read the user guide and implement same to same but I face the same problem.

You have to load session library. Add a __construct method to the Login controller and load the library. This will let you access to the library's functions in any method inside the controller. 

I use to get the session data in the controller instead of the model. Then I pass the necessary values to the model's function in the arguments, but that is a personal preference.

PHP Code:

public function __construct()
{
        parent::__construct();
        $this->load->library('session');
        ...
} 


Please check  the attachment  give me solutions....

please check config file session code:-
--------------------------------------------------------
$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = NULL;
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;

You need to set the sess_save_path

Create a folder named writable in ./application folder.

./application
-- writable

Then setup your sessions like below.

PHP Code:

$config['sess_driver']             = 'files';
$config['sess_cookie_name']        = 'ci_session';
$config['sess_expiration']         = 7200;
$config['sess_save_path']          = APPPATH.'writable';
$config['sess_match_ip']           = FALSE;
$config['sess_time_to_update']     = 300;
$config['sess_regenerate_destroy'] = FALSE; 


Hope you get it now...
