        $cek = $this->web->proseslogin($user,$pass);
        $hasil = count($cek);           

        if ($hasil > 0){                
        $pelogin = $this->db->get_where('tb_user',array('username' => $user,'password' => $pass))->row();               
            $level = $pelogin->level;               
            $data= array ('level' => $level,
                                'logged_in'=> true,

Answer 1

Setting:

//$_SESSION['idkec'] = "kec_id_user"; //test set manual session
$this->session->set_userdata('idkec', 'something');

Getting:

//session_start(); // don't do this
echo $this->session->userdata('idkec');
