function fb_session_exit in Drupal for Facebook 6.2

In canvas pages, cookies do not work. To enforce sessions, we "spoof" a cookie (see fb_settings_session_helper()). Sometimes drupal changes the session id on us, we need to change it back, because the canvas page will never honor the new value.

This function is called from fb_exit();

File

./fb_session.inc, line 25

This file is a replacement for Drupal's session.inc. Although not truly a replacement, as we include the default session.inc to do the heavy lifting. In this file we set up some variables and functions to handle facebook-controlled sessions.

Code

function fb_session_exit() {
  if ($id = fb_settings('fb_session_id_force')) {
    if ($id != session_id()) {

      // In case we are called after sess_write.

      //db_query("UPDATE {sessions} SET sid='%s' WHERE sid='%s'",

      //        array($id, session_id()));
      // We are called before sess_write.
      session_id($id);
    }
  }
}
