If all you want to do is trap empty fields etc, you might as well use
JavaScript:
<script language="JavaScript">
<!--
function FormCheck()
if (document.formname.fieldname.value == "") {
alert("Please enter something into the field");
document.formname.fieldname.focus();
return false;
}
//-->
</script>
and
<form name="formname" method="post" action="/cgi-bin/yourscript.pl"
onSubmit="return FormCheck()">
etc.
Your user is gong to be happier just to see an alert box if they've missed
out a field, rather than having to submit the form and wait for an error
feedback page from your script.
(Of course, if you need to validate the data for security or related
purposes, you should also validate on server-side, as it's easy to hack JS
validation.)
