Token authentication- "The form has become outdated" and rules issues

Question

I'm using the Token Authentication and Privatemsg modules together. When a user receives an e-mail notification that they he/she has received a private message, I have placed a link (using a token provided by the Tokenauth module in a query string) that allows the user to log in and see the message.

At the bottom of the page is the message reply form. I would like the user to be able to reply via this form as well (without logging in, via token authentication). However, when I tested this, I received the following error:

The form has become outdated. Copy any unsaved work in the form below and then reload this page.

A Google search revealed this helpful comment on drupal.org:

So it seems you would have to either

unset($form['#token']) or $form['#token'] = NULL

Privatemsg has two message creation forms, the new message form and the reply to message form.

To fix the new message form, I added unset($form['#token']); to hook_form_privatemsg_new_alter() (new messages) and hook_form_privatemsg_form_reply_alter() (replies). I tested this and new private messages as well as replies can now be sent.

I then disabled caching for the privatemsg module so that the messages would always be refreshed.

However, I have a rule that is set to Show a message on the site ("Your message was sent to User X!") whenever a private message or reply is sent; this rule is not triggered when a private message is sent if the user is authenticated via Tokenauth even though the private message is saved to the database properly and displayed upon page refresh.

How can I make sure rules are still triggered when authenticated via Tokenauth?

From my point of view, it would seem Rules are not being triggered at all. You could, however, try invoking a rule manually by placing a rules_invoke_event() call within inside a custom form submit function.

Note that the #submit property on Drupal forms allow multiple submit handlers to be called for a single form.

In the hook_form_privatemsg_new_alter() and hook_form_privatemsg_form_reply_alter() form alters you have implemented you should be able to find and modify the #submit property. Just do something like:

// Implementation of hook_form_FORMID_alter().
patricks_form_privatemsg_new_alter($form, &$form_state) {
  ...
  $form['#submit'][] = 'patricks_privatemsg_submit';
  return $form;
}

Then in your submit handler you can use the rules_invoke_event():

function patricks_privatemsg_submit($form, &$form_state) {
   drupal_set_message(t('The form has been submitted.'));
   // Pass parameters for the variables provided by this event, as defined in hook_rules_event_info()...
   rules_invoke_event('privmsg_foo_rule', $foos, $barf, $bam);
}

If for some reason you get a rules_invoke_event() function not found error, just add a module_load_include() to your submit handler before invoking the rule.
