Simple Form Validation question!

Thanks again for the quick reply.

One more question is there any way for the user to specify how long they want until the session cookie will expire?

A way of overriding the $config['sess_expiration'] so when the users login they can input say 30mins?

I have tried to destroy the session cookie and make a new one but with no luck. Maybe someone could point me to some links etc.

Code:

function _set_cookie($expire)
    {
        $CI =& get_instance();
        $CI->load->helper('cookie');

        $expire = (60 * $expire) + time();

        $cookie_name = $CI->config->item('sess_cookie_name');
        $cookie_data = get_cookie($cookie_name, TRUE);

        delete_cookie($cookie_name);

        setcookie(
                $cookie_name,
                $cookie_data,
                time() - 31500000,
                $CI->config->item('cookie_path'),
                $CI->config->item('cookie_domain'),
                0
                );

        setcookie(
                $cookie_name,
                $cookie_data, // session id
                $expire,
                $CI->config->item('cookie_path'),
                $CI->config->item('cookie_domain'),
                0
                );
    }

Thanks again!
