trackSubmit automatically puts a hidden value in the form and the form
won't validate if that value isn't in the submitted values. You don't
have to do anything special to use it. It's mostly there so that you
can have 2 forms on one page so that QF can know which one was
submitted.

Well, this is because you're posting to form2.php, which doesn't check
to see if form1.php is valid. PHP scripts are run completely, the
output is sent to the browser, and the browser sends a response back.
In this case, the browser is sending the response to form2.php, which
isn't dealing with the submit of the first form.

A better solution would be to leave the action alone and let the form
submit to the page that created it (this is the "right" way to do it).
Then the validation will work. If the form validates, process the
data, then redirect to the second for with a header('Location:
http://...');
