facebook api doesn't retrieve email and birthday - facebook

Question

I use facebook sdk api with symfony, in the below $user_profile array he can retrieve every information but email and birthday.
require 'facebook.php';
$app_id = sfConfig::get('app_facebook_app_id');
$app_secret = sfConfig::get('app_facebook_secret_key');
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
));
$user = $facebook->getUser();
if ($user) {
try {
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
if ($user) {
$location= $user_profile['location']['name'];
$gender = $user_profile['gender'];
$user_info = array(
'uid' => $user_profile['id'],
'first_name' => $user_profile['first_name'],
'last_name' => $user_profile['last_name'],
'email' => $user_profile['email'],
'birthday' => $user_profile['birthday'],
'gender' => $user_profile['gender'],
);
when I use print_r($user_profile) it return:
Array (
[uid] => 100004246655890
[first_name] => Ala
[last_name] => Hamad
[email] =>
[birthday] =>
[gender] => male
)
the email and birthday empty.

Answer 1

Nowhere in your code does it appear that you're requesting the Permission needed to access the user's email address or birthday
Check the permissions doc and make sure you're requesting the email and user_birthday permissions in your Authentication code.

Answer 2

If you don't receive these information, one of the cause is because the user configuration prohibits sharing them and Facebook don't send the warns.
Because some users, in the configuration, prohibits sharing the email or other information.

Answer 3

I searched for how to write that in code, then I found that I have to request email permission within the scope in the login url:
$params = array(
'redirect_uri' => url_for('sfGuardAuth/loginWithFB', true),'scope' => 'email,user_birthday,user_location'
);
$loginUrl = $facebook->getLoginUrl($params);
