[TYPO3-dev] Logoff hooks

[Dave Sexton]

Aha!

I can use the reference back to t3lib_userauth and call the
getLoginFormData function to retrieve the state of the login form (if
any). This will indicate if a logout button has been clicked.

Eg.:

function logoff_post_processing (&$params, &$reference) {
  $form = $reference->getLoginFormData();
    if (isset($form['status']) && $form['status']  == 'logout') {
	// Do forum lgout
    }
}
