Codeigniter - Session expiration and “remember me” feature

Question

I\'m building a \"Remember Me\" feature in Codeigniter, normally I see libraries/projects setting a cookie on the user with a token, this token gets saved in the database an

Answer 1

The simpliest solution that I have found for this problem is to just modify the cookie created by Codeigniter by this way:

        $this->session->set_userdata('user', $user); // a cookie has been created
        if($this->input->post('remember_me'))
        {
            $this->load->helper('cookie');
            $cookie = $this->input->cookie('ci_session'); // we get the cookie
            $this->input->set_cookie('ci_session', $cookie, '35580000'); // and add one year to it's expiration
        }
