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_track($fb, $fb_app, $user) {

  // Keep track of all our app users.  We need this info when updating
  // profiles during cron.  We keep session keys in case user has an
  // infinite session, and we can actually log in as them during cron.
  // In special cases, do not modify the uid column.
  $fb_app_data = fb_app_get_data($fb_app);
  $fb_user_data = $fb_app_data['fb_user'];

  // our configuration
  if (!$user->uid || $user->uid == $fb_user_data['not_logged_in_uid'] || $user->uid == $fb_user_data['logged_in_uid']) {

    // Should we even keep data for users who have not added???
    $result = db_query("UPDATE {fb_user_app} SET time_access=%d, session_key='%s', session_key_expires=%d, uid=NULL WHERE apikey='%s' AND fbu=%d", time(), $fb->api_client->session_key, $fb->session_expires, $fb_app->apikey, fb_facebook_user($fb));
  }
  else {

    // Uid is accurate.
    $result = db_query("UPDATE {fb_user_app} SET time_access=%d, session_key='%s', session_key_expires=%d, uid=%d WHERE apikey='%s' AND fbu=%d", time(), $fb->api_client->session_key, $fb->session_expires, $user->uid, $fb_app->apikey, fb_facebook_user($fb));
  }
  if ($result === FALSE) {
    watchdog('fb_user', t("Failed to update fb_user_app table."), WATCHDOG_ERROR);
