CodeIgniter 3 and sessions

I updated to CodeIgniter 3 recently, following this guide:
CI3: upgrade 3.0 from 2.2.1.

I set up this configuration in application/config/config.php file:

$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session_my_site';
$config['sess_expiration'] = 604800; // 1 week
$config['sess_save_path'] = NULL;
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;


Is there something wrong here? My session is destroyed after a few hours...

Answer

In your save path you need to set up a location folder. Use 'files' as session driver preferred. As like below I have set up a cache to store sessions in BASE PATH which is setting folder. Make sure you have auto loaded sessions and $config['encryption_key'] = '' add key.

You can set up a database sessions but this works just as well. Make sure folder permissions 0700

http://www.codeigniter.com/userguide3/search.html?q=session&check_keywords=yes&area=default

$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 1440;
$config['sess_save_path'] = BASEPATH . 'yourfoldername/cache/';
$config['sess_match_ip'] = TRUE;
$config['sess_time_to_update'] = 300;

Once that is done then you should be able to do something like.

$this->load->library('session');
$data_session_set = array('logged' => 1, 'username' => $this->input->post('username'), 'user_id' => $this->user_auth->get_id()); 
$this->session->set_userdata($data_session_set);
