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_get_fbu($uid, $fb_app) {
  static $cache = array();
  if (!$cache[$uid]) {
    $cache[$uid] = array();

    // Look up this user in the authmap
    $result = db_query("SELECT * FROM {authmap} WHERE uid=%d AND authname LIKE '%@facebook.com'", $uid);
    while (!$fbu && ($data = db_fetch_object($result))) {

      // get the part before the '@'
      $substr = substr($data->authname, 0, strpos($data->authname, '@'));

      // then split at the '-'
      $parts = explode('-', $substr);
      if ($parts[1]) {

        // $parts[1] is app id
        $cache[$uid][$parts[1]] = $parts[0];
      }
      else {
        $cache[$uid]['global'] = $parts[0];
