Form rules in QF were special callbacks set with addFormRule():
http://pear.php.net/manual/en/package.html.html-quickform.html-quickform.addformrule.phpThey were given all form's values and could return errors for several form
elements at once.
In QF2 you can add a callback rule to the form, as is done in above tutorial,
and it will receive all form's values. However it will set an error for the form
itself, not for several elements in the form. A better approach is a custom rule
subclass as written in my older email quoted by Mark.
