Facebook Connection from widget

**ing.jose.campo** · 2009-12-23, 15:22

Hello, I'm trying to connect my widget with facebook. Does anyone know how to do that? I only need to read and publish in the newsfeed but I can't even authenticate to the system. Is there any widget that already do this? Or is there any prefered method/API I can use?

Thanks,
Jose Campo

Yeah i would like to know how to do this too..
I did a lot of research, and found out that you need to make an application on facebook (no code, just sort of register it) so u can get an API key.
The part where i'm stuck is this bit.. If i'm right then u need a Facebook Connect URL, even if ur making a mobile application.
Where does this url come from? Since i dont have a website, just the mobile app.
So basically, how can i implement the basic functionality of logging in and publishing to the stream..?
I'm using aptana studio 2.0 with the WRT plug-in with JavaScript offcourse.

I got stuck @login

the FBlogin button is in IFRAME and apparently has "javascript:window.open" and does not work under WRT environment should have "javascript:widget.openURL"

the FBlogin button works in mobile browser, but not in WRT

(

keep looking for a solution..

the only solution that I have is for example to "connect to facebook" only my top from games... although the top will open in a browser

Code:

<?php

define('YOUR_APP_ID', '*********');
define('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;
}

$cookie = get_facebook_cookie(YOUR_APP_ID, YOUR_APP_SECRET);

$user = json_decode(file_get_contents(
    'https://graph.facebook.com/me?access_token=' .
    $cookie['access_token']));

$friends=file_get_contents(
    'https://graph.facebook.com/me/friends?access_token=' .
    $cookie['access_token'])
?>
<html>
  <body>
    <?php if ($cookie) { ?>
      Welcome <?= $user->name ?>(<?= $user->id ?>)<?= $user->id ?>
      <?= $friends ?>
    <?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: '<?= YOUR_APP_ID ?>', status: true,
               cookie: true, xfbml: true});
      FB.Event.subscribe('auth.login', function(response) {
        window.location.reload();
      });
    </script>
  </body>
</html>
