..., which means this validation doesn't run (it's run when form1.php is first
displayed, but that's not what you want).
IOW your validation code must be at wherever you set the form action as.
There are at least a couple of ways you can do this:
1) If your forms are related, have a single page which deals your two (or more
forms). You have to keep track of which stage the user is at (ie if they've
filled in form1 then you should display form2).
2) Or have it as two pages (like you have now) but in form1.php have the
action="form1.php" (so it processes its form). After you've processed it,
stick the values into some session variables then use header() to redirect to
form2.php.
Or you can have a look at www.phpclasses.org for some classes which can build
and validate forms for you.
