Question

I am creating fb login with the php ,
the problem is that the email of user is not returning from facebook,
FBID and USER NAME is returning.
The same code i have done for another project is working but for the new one is not working
the code is like this
require 'src/facebook.php'; // Include facebook SDK file
$facebook = new Facebook(array(
'appId' => 'XXXXXXXXXXX', // Facebook App ID
'secret' => 'XXXXXXXXXXXXXXXXX', // Facebook App Secret
'cookie' => true,
));
$user = $facebook->getUser();
if ($user) {
try {
$user_profile = $facebook->api('/me');
$fbid = $user_profile['id']; // To Get Facebook ID
$fbuname = $user_profile['username']; // To Get Facebook Username
$fbfullname = $user_profile['name']; // To Get Facebook full name
$femail = $user_profile['email']; // To Get Facebook email ID
/* ---- Session Variables -----*/
$_SESSION['FBID'] = $fbid;
$_SESSION['USERNAME'] = $fbuname;
$_SESSION['FULLNAME'] = $fbfullname;
$_SESSION['EMAIL'] = $femail;
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
if ($user) {
header("location:fblogin.php");
} else {
$loginUrl = $facebook->getLoginUrl(array(
'scope' => 'email', // Permissions to request from the user
));
header("location: " . $loginUrl);
}

Answer 1

$user_profile = $facebook->api('/me?fields=name,email');
It´s called "Declarative Fields", see changelog. Btw, you can´t get the username anymore.
