Hi, here’s a piece of code I’m using in my application to allow users to login using FB account.
Can’t help you with Google auth…
please note, in the config params section you need to provide:
'FB_APP_ID'=> '<id of your FB AP>',
'FB_SECRET_KEY' => '<secret key>',
'FB_API_KEY' => '<api key>',
// url of user-controller / handshake action. including your domain etc. full valid url.
'FB_HANDSHAKE_URL' => "http://mypenisinyourcoffee.com/fbuser/handshake",
<?php

public function actionIndex()
{
$this->redirect(
"https://graph.facebook.com/oauth/authorize"
."?type=web_server"
."&redirect_uri=".Yii::app()->params['FB_HANDSHAKE_URL']
."&client_id=".Yii::app()->params['FB_APP_ID']
);
}
/**
* action called by Facebook, after the user accepted the application
*/
public function actionHandshake()
{
if (!isset($_REQUEST['code']))
{
if (isset($_REQUEST['error_description']))
$error = $_REQUEST['error_description'];

$error = "Auth error";
throw new CHttpException(403, $error);

$identity = new FbUserIdentity($_REQUEST['code'], Yii::app()->params['FB_HANDSHAKE_URL']);
if ($identity->authenticate())

Yii::app()->user->login($identity);
$this->redirect('/');

Thank you migajek,
I need also for SDK or no ?
you’re welcome 
nope, you don’t need SDK here. this code is standalone.
you’ll however need to setup Facebook Application to have your app id, api key and secret key.
// you’ll need to translate error messages to english 
Thanks, but please give me the code which i do in layout of in views site
thank you friend help me.
??
it does not require any code in views at all.
just navigate to "index" action of FbUserController.
i got errur
may be i have the errur in : ‘FB_HANDSHAKE_URL’
FB_HANDSHAKE_URL must be like this code? :
‘FB_HANDSHAKE_URL’ => “http://mysite.com/fbuser/handshake”,
yup, it should be like this.
first of all make sure the address is correct.
also, did you configured Facebook Application ( https://www.facebook.com/developers/#!/developers/apps.php ) correctly? You need to provide your website domain (path).
Thank you migajek, now it’s good but is still one problem is :
Unable to resolve the request "fbuser/handshake".
The requested URL was not found on this server. If you entered the URL manually please check your spelling and try again.

this extension provides facebook, google, in a same way. transparent for your application.

It worlks to login with google and facebook. But the facebook id or username are not adding to database.
