I need to present the user login form from a callback function that I have registered in hook_menu(), at that specific URL. When the user logs in, I need to direct them back to that URL to present them with other options. Currently, I call:
if (!user_is_logged_in()) drupal_goto('user/login');
Of course, that takes them to the login page. I imagine I need to call drupal_get_form() to present the form from here, but how do I direct them back to this page after login?
