Facebook app- getting name of a user doesn't work

I'm creating a Facebook app with the PHP SDK 3.2.0 and I encountered a problem. When I'm making an API call, trying to get name of a user nothing occours. I'm using the example from github.com and still can't achieve what I'm loking for.

require 'src/facebook.php';

$facebook = new Facebook(array(
  'appId'  => 'xxx',
  'secret' => 'xxx',
));

// Get User ID
$user = $facebook->getUser();

if ($user) {
  try {
    // Proceed knowing you have a logged in user who's authenticated.
    $user_profile = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
  }
}

Authenticated Referrals are deprecated and will be removed in February 2013.

That being said, i recommend using FB.login for user login:

https://developers.facebook.com/docs/reference/javascript/FB.login/

If you don´t want to use the Javascript SDK, there is also an easier way with the PHP SDK:

https://developers.facebook.com/docs/reference/php/facebook-getLoginUrl/

Everything is explained well in the docs. Just some more lines of code for you.

Well, you need to verify first if you have an active access token. If not you should show the Facebook login button.

<?php
$userId = $facebook -> getUser();

 if ($userId) { 
  $userInfo = $facebook->api('/' . $userId); ?>
  Welcome <?= $userInfo['name'] ?>
<?php } else { ?>
<div class="fb-login-button" data-show-faces="true" data-width="200" data-max-rows="1"></div>   
<?php } ?>

According to your code it should be like this:

<?php
require 'src/facebook.php';

$facebook = new Facebook(array(
  'appId'  => 'xxx',
  'secret' => 'xxx',
));
?>
<script>
  window.fbAsyncInit = function() {
    FB.init({
      appId      : 'xxx', // App ID
      channelUrl : 'http://YOURDOMAIN.com/channel.php', // Channel File
      status     : true, // check login status
      cookie     : true, // enable cookies to allow the server to access the session
      xfbml      : true  // parse XFBML
    });
    FB.Event.subscribe('auth.login', function(response) {
      window.location.reload();
      //alert(me.name);
    });
    }
</script>


<?php
$userId = $facebook -> getUser();

if ($userId) { 
  $userInfo = $facebook->api('/' . $userId); ?>
  Welcome <?= $userInfo['name'] ?>
<?php } else { ?>
<div class="fb-login-button" data-show-faces="true" data-width="200" data-max-rows="1"></div>   
<?php } ?>

    <script>
        // Load the SDK Asynchronously
        ( function(d) {
                var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
                if (d.getElementById(id)) {
                    return;
                }
                js = d.createElement('script');
                js.id = id;
                js.async = true;
                js.src = "//connect.facebook.net/en_US/all.js";
                ref.parentNode.insertBefore(js, ref);
            }(document));
    </script>

You should have a channel.php file in your server, that would have the following content:

<?php
$cache_expire = 60*60*24*365;
header("Pragma: public");
header("Cache-Control: max-age=".$cache_expire);
header('Expires: ' . gmdate('D, d M Y H:i:s', time()+$cache_expire) . ' GMT');
?>
<script src="//connect.facebook.net/en_US/all.js"></script>
