You need to do server-side validation (always a good idea even if you're
100% certain that your JS will catch it all).
Instead of redirecting back to the form, what you could do is just output
a page which *looks* like the original form, but with the non-problem
fields pre-populated with what the user put in before.
Or even more radical, don't output those as editable fields at all. Put
them in as
text as a reassurance (and carry the data as hidden fields), but only let
the user touch the fields which still have problems.
Naturally this is a recursive process.
Cheers
