>From the code snippets you've provided, you're already on the right
track. You define the form as a separate class, and instantiate it when
needed. All you need to do is pass the appropriate method and action to
it when instantiating it -- the filters and validators will be the same
regardless of instance as long as you're not customizing them on a
per-action basis (which you don't appear to be doing anyways).
It's simply a matter of calling $form->isValid(...). It's as easy as
that, really. :)
