facebook application : get birthday - facebook

Question

I would like to know how to get the date of birthday of the user of facebook.
Here is the code which deal with facebook api :
<?php require 'src/facebook.php';
define("FB_APP_ID","***");
define("FB_SECRET","***");
$facebook = new Facebook(array(
'appId' => FB_APP_ID,
'secret' => FB_SECRET,
'cookie' => true,
));
$currentUser = $facebook->getUser();
if($currentUser) {
try
{
$facebook_profile = $facebook->api('/me');
$friends_fields = $facebook->api('/me/friends');
}
catch (FacebookApiException $e)
{
print_r($e);
$user = null;
}
}
$loginUrl = $facebook->getLoginUrl(
array(
'scope' => 'user_birthday, birthday, date_birthday, email, offline_access, publish_stream'
)
);
$logoutUrl = $facebook->getLogoutUrl();
?>
I tried $facebook_profile['user_birthday'] and $facebook_profile['birthday']
But it does not work.
I don't know how to do ? Can you help me please ?

Answer 1

The correct permission for birthday is user_birthday
Verify you have the permission
$permissions = $facebook->api('/me/permissions');
$permissions["data"][0]["user_birthday"];
Seeing that you have facebook_profile, you should just dump the contents of that response to see what you do have.
Also ensure the user did set his/her birthday...

Answer 2

There's probably more than one way to do it, but you should be able to get the user's birthday from an FQL call via the SDK api() method:
$result = $facebook->api(array(
'method' => 'fql.query',
'query' => 'SELECT birthday_date FROM user WHERE uid = me()',
));
$birthday = $result[0]['birthday_date'];
You'll need to have user_birthday or friends_birthday permissions to read the birthday and birthday_date fields.
