This module allows Drupal user records to be associated with Facebook user ids. It can create local user accounts when Facebook users visit an application's canvas pages.

Code

function fb_user_post_add_check() {
  global $fb, $fb_app, $user;

  // This page is for canvas pages only
  if (!$fb) {
    drupal_access_denied();
    exit;
  }

  // redirect will be set if we've called $fb->require_add.  In this case
  // we forward the user on.
  if ($_REQUEST['redirect']) {
    if (function_exists('fb_canvas_fix_url')) {

      // Redirect to a canvas page
      $url = fb_canvas_fix_url($_REQUEST['redirect'], $fb_app);
      if (fb_verbose()) {
        watchdog('fb_debug', "post_add_check redirecting to {$url}");
      }
      $fb
        ->redirect($url);
      exit;
    }
    else {

      // XXX is this still necessary?
      _fb_user_sync_redirect($_REQUEST['redirect']);
    }
  }

  // This function returns only if post add page needs to be rendered.  Otherwise user is redirected.
