Remember me feature in code in CodeIgniter

Question

I am trying to have a remember me feature in CodeIgniter. My issue is that after 2 hours or so, my sessions are expiring.

I have tried using:

$remember = $this->input->post('remember_me');
if($remember) {
    $this->session->sess_expiration = '1209600';
}

And I am suspecting its because of:

$config['sess_expiration']      = 7200;

in config.php. Maybe it's overriding the maximum session time. Any help on this will be appreciated.

Answer 1

Did you try like this...

$remember = $this->input->post('remember_me');
if($remember) {
    $this->session->sess_expiration = '1209600';
     $this->config->set_item('sess_expiration', 1209600);
}

If you would like to dynamically set a config item or change an existing one, you can do so using:

$this->config->set_item('item_name', 'item_value');
