    public function index()
    {
        require_once 'openid.php';
        $openid = new LightOpenID("localhost");
        $openid->identity = 'https://www.google.com/accounts/o8/id';
        $openid->required = array(
            'namePerson/first',

            'contact/postalCode/home',
            'contact/country/home',
            'pref/language',
            'pref/timezone',  
        );
//  $openid->returnUrl = 'http://localhost/login_thirdparty/login_google.php';

    $openid->returnUrl = 'http://localhost/login_thirdparty/codeigniterlogin/index.php/logingoogle/loginAuth';

//  echo 'Login with Google';

        $data['openid'] = $openid;
