FB PHP SDK Issue

Ziycon

I'm trying to integrate the Facebook PHP SDK to allow users to login onto a website with their Facebook account. Below is the code I'm using, I'm logged into Facebook and the first time I go and click on the login link it pops up with the 'allow Facebook share profile information with this website' message which is grand, when I click OK it redirects back to the login page on the website still displaying the login URL.

I did notice that there is a code parameter now in the address bar url with a long string.

Can anyone suggest if I'm missing something or doing something wrong?!

As always any help greatly appreciated, thanks.

$vFacebook = new Facebook(array(
  'appId' => '....',
  'secret' => '....',
  'fileUpload' => false,
  'allowSignedRequest' => false,
));
$vUID = $vFacebook->getUser();
$vLoginURL = $vFacebook->getLoginUrl(); 

if ($vUID)
{
	try {
		$vFBUserProfile = $vFacebook->api('/me','GET');
		var_dump($vFBUserProfile);
		exit();	
	}
	catch (FacebookApiException $e)
	{
		echo 'Please <a href="' . $vLoginURL . '">login.2</a>';
		error_log($e->getType());
		error_log($e->getMessage());
	}
}
else
{
	echo 'Please <a href="' . $vLoginURL . '">login.1</a>';
}

Figured it out, after debugging for hours. Make sure you have the fb_ca_chain_bundle.crt available to the base_facebook.php class otherwise you will just keep getting zero returned by getUser().
