I'm trying to rewrite a Facebook app (a PHP script embedding a small multiplayer Flash game) from old FBML to new iFrame type and it kind of works:
<?php
require_once('facebook.php');
define('FB_API_ID', '182820975103876');
define('FB_AUTH_SECRET', 'XXX');
$facebook = new Facebook(array(
'appId' => FB_API_ID,
'secret' => FB_AUTH_SECRET,
'cookie' => true,
));
if (! $facebook->getSession()) {
printf('<script type="text/javascript">top.location.href="%s";</script>',
$facebook->getLoginUrl(
array('canvas' => 1,
'fbconnect' => 0,
#'req_perms' => 'user_location',
)));
} else {
try {
$me = $facebook->api('/me');
$first_name = $me['first_name'];
$city = $me['location']['name'];
$female = ($me['gender'] != 'male');
$fields = $facebook->api('/me', array(
'fields' => 'picture',
'type' => 'large'
));
$avatar = $fields['picture'];
# then I print swf tag and pass first_name;city;avatar to it
} catch (FacebookApiException $e) {
print('Error: ' . $e);
}
}
?>
but I think that the call to get the user profile picture causes my script to perform a 2nd CURL fetch, which is probably avoidable? And also I'd like to use the new GRAPH API and not the old REST API - but I'm not sure how to rewrite that call (and I need to get the large and direct user picture).
If you know the user ID, just use:
<img src="http://graph.facebook.com/<UID>/picture?type=large" />
Also note that you can use that URL to retrieve the contents via cURL. If necessary, you can also use cURL to follow the redirects and get the final URL.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,
"http://graph.facebook.com/<UID>/picture?type=large");
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_exec($ch);
$url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);
curl_close($ch);
var_dump($url);
