Show user's name on Facebook Page Tab

I have a fan page on Facebook and I'd like to show a christmas message to the people who like the page.

The idea is:

If user likes page > say: "Merry Christmas first_name" if user doesn't like the page > show generic message

I thought I'd be able to get the user's 1st name to display just that, since I don't want to store anything, but so far no success.

My code is:

require 'facebook.php';

$facebook = new Facebook(array(
  'appId'  => 'xx',
  'secret' => 'xx',
  'cookie' => true,
));

$session = $facebook->getSession();

$me = null;

if ($session) 
{
  try 
  {
    $uid = $facebook->getUser();
    $me = $facebook->api('/me');
  } 
  catch (FacebookApiException $e) 
  {
    error_log($e);
  }
}

$name = $me['first_name'];
   
echo 'Merry Christmas x ' . $name . ' x ' . $uid;

But all it echoes is: "Merry Christmas x x 106998XX369535"

Where the number is the page's id, not the user's id.

Is there any way to do this without asking the user's permission?

$json  = file_get_contents("http://graph.facebook.com/$uid");
$fdata = json_decode($json);
$fname = $fdata->name;
echo 'Merry Christmas x ' . $fname . ' x ';

I've found the answer.

Just use: to show the user's name on a TAB/Canvas app.

It also works within the Static FBML app.

Writing:

Merry Christmas <fb:userlink uid="loggedinuser"/>

Will show:

Merry Christmas John Smith

if John Smith is viewing it :)

The name will be formatted as a link, but you can style it with CSS.

You cannot get any information about the user unless the user gives permission. Unfortunately.

But with "OAuth 2.0 for Canvas" you do receive a the signed_request POST. And this way is the only way to go about it; http://developers.facebook.com/docs/authentication/canvas

But user still needs to authorize your application.
