I might be dense, but it still isn't the problem. Of course I can check
if both are empty (invalid), that's easy.
Why doesn't PHP have an if/then/else way of doing things... or, can I do
a check for criteria two _before_ the redirect?
something like:
if (not valid)
then (check criteria two)
if both = invalid, then redirect
if both = valid, then -> check code
if code valiates, then send mail
