[pmwiki-users] PmForm - change summary and cancel button

Check out BlogIt, which uses PmForms, that might help (or might be too 
complex to easily grab info quickly).

Setup some form of event handler. From BlogIt:
SDV($HandleActions['bi_be'], 'bi_HandleEdit'); SDV($HandleAuth['bi_be'], 

In your case that might be:
SDV($HandleActions['my_edit'], 'my_HandleEdit'); 
SDV($HandleAuth['my_edit'], 'edit');

in my_HandleEdit() something like (make sure you declare $ChangeSummary, 
$_POST, etc, as global in your function):
   if ($_POST['target']=='savedata' && @$_POST['save']{
     $ChangeSummary = $_POST['ptv_MyPTV'];

Search for 'cancel' in BlogIt for actual use. Basically:
   if ($_POST['cancel'] && in_array($_REQUEST['target'],$bi_Forms))

This is checking for the Cancel button being clicked, and then checking 
that the form being submitted is one being managed by PmForms. 
Simplified for your case that might be:
   if ($_POST['cancel'] && $_REQUEST['target']=='savedata')

Hope that gets you in a direction to move forward a step.
