As PHP runs on the server while the form is on the client, there is just
the solution that you use javascript to check if fields are filled
(document.form[0].element[0].value...) but that is quite insecure,
because the user can deactivate Javascript. The other solution is to
check each $_GET or $_POST-element (which you should always do) and
redirect the user back to the form (populated with those values which
were okay)

Best regards,
