Using flags with DFB

writing argument and filter handlers for views is failry involved. You can find reasonable doc for it on drupal.org. Look at fb_views.module for an example. It defines an argument handler which limits a view to nodes authored by friends of the given user.

If you get it working, please post the code here. It might help others define similar filters.

I just tried enabling the devel query log, and it appears fine on canvas pages as well as regular pages. Is that what you're talking about?

When you view the canvas pages, you're probably a user without permission to view devel info. Try letting all users (anon and registered) see devel info.

ITs a matter of getting views to add fb_user_fbu to the join clauses. I'm not expert enough to tell you exactly how. Coding for views is tricky.

extending drupal for facebook fb_friends using drupal flag_friends ...
i build a function that flag all facebook friends that have added the application as drupal 'friends':

function _moodboard_flag_fbfriends($uid) {
    global $fb, $fb_app;
    $fbu = _fb_user_get_fbu($uid,$fb_app);
    if ($fbu) {
      $flag = flag_get_flag('friend');
      #$friends = flag_friend_get_friends($uid); // $friends[$uid]
      // Get list of friends who have authorized this app.
      $rs = $fb->api_client->fql_query("SELECT uid FROM user WHERE has_added_app=1 AND uid IN (SELECT uid2 FROM friend WHERE uid1 = $fbu)");
      if (isset($rs) && is_array($rs)) {
          foreach ($rs as $friend_data) {
              $friend_fbu = $friend_data['uid'];
              $account = fb_user_get_local_user($friend_fbu, $GLOBALS['fb_app']);
              if ($account->uid) {
                  $fuid = $account->uid;
                  $status = flag_friend_determine_friend_status($flag, $uid, $fuid);
                  if ($status == FLAG_FRIEND_UNFLAGGED) {
                      db_query("INSERT INTO {flag_friend} VALUES(%d, %d, %d)", $uid, $fuid, $_SERVER['REQUEST_TIME']);
                  }
              }
          }
      }
  }
}

to check if a user has new appz friends you call:

      _moodboard_flag_fbfriends($user->uid);

I'm simply trying to offer the ability to flag a module with no specific views and I get a really long error pop-up when I click the flag I have created.

An HTTP error 0 occurred.

I have no idea where to even begin. What a drag as this is a major functionality of the facebook app.

JoshuaBud, where to begin is that the flag module should probably use a URL that starts with http://your-site.com, and not http://apps.facebook.com/... I don't know much about the flag module, so I can't say how it passed URLs around.
