I'm still trying to get my site working with Facebook Connect. I've been using the guide here.
The following code is run from localhost (My app ID and secret ID have been removed):
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<?php
define('YOUR_APP_ID', '**MY APP ID**');
define('YOUR_APP_SECRET', '**MY SECRET APP ID**');
$cookie = get_facebook_cookie(YOUR_APP_ID, YOUR_APP_SECRET);
function get_facebook_cookie($app_id, $app_secret) {
$args = array();
parse_str(trim($_COOKIE['fbs_' . $app_id], '\\"'), $args);
ksort($args);
$payload = '';
foreach ($args as $key => $value) {
if ($key != 'sig') {
$payload .= $key . '=' . $value;
}
}
if (md5($payload . $app_secret) != $args['sig']) {
return null;
}
return $args;
}
$user = json_decode(file_get_contents(
'https://graph.facebook.com/me?access_token=' .
$cookie['access_token']));
?>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml">
<?php if ($cookie) { ?>
<li> Welcome <?= $user->name ?></li>
<?php } else { ?>
<fb:login-button></fb:login-button>
<?php } ?>
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script>
FB.init({appId: '<?= **MY APP ID** ?>', status: true,
cookie: true, xfbml: true});
FB.Event.subscribe('auth.login', function(response) {
window.location.reload();
});
</script>
</html>
But gives me the following errors when I try to run it via WAMP:
Notice: Undefined index: fbs_**MY APP ID** in C:\wamp\www\fbtest.php on line 12
Notice: Undefined index: sig in C:\wamp\www\fbtest.php on line 20
Warning: file_get_contents() [function.file-get-contents]: Unable to find the wrapper "https" - did you forget to enable it when you configured PHP? in C:\wamp\www\fbtest.php on line 30
Warning: file_get_contents(https://graph.facebook.com/me?access_token=) [function.file-get-contents]: failed to open stream: Result too large in C:\wamp\www\fbtest.php on line 30
However, I suspected this might be a problem with WAMP. So I put this code live on a private server and got no errors like this... However, when I try to click the Login Facebook button, it opens a new window where it only tells me An error occurred. Please try again later.
I'm unsure how to resolve this either way.
