Just a note. If the echo message works. Then Registered globals are one and you can do that $formfieldname stuff. However it is recommended by the PHP docs to use the $_POST['formfieldname'] method because if you ever switch servers,have that turned off on the server, or go to distribute the program it can cause problems. Plus it is a security risk.

The $formfieldname can be modified via a URL or "GET" form method.

using $POST[] ensures that the value come from a form "POST" method.

Thanks for the help, and the heads-up on HTML's moodiness.

I modified the POST quotes , and I think that fixed it. Here's the final code.

The Form
==========

The Processor
=============
if (($_POST['subemail']=="") || ($_POST['subemail']==NULL))
{
header ("Location: noemail.htm");
}

else
{
echo "It works and my email is $subemail";
}

shanda: your method requires registered globals to be on if I am not mistaken. Renegade has given you the proper code and comment on the "post" thing.

HTML gets cranky if you are inconsistent, meaning you quote one attribute and don't on another.

If you can't get renegades to work

simple echo both values out and see if they contain something.

If not then that would equal "", but try NULL instead or even add an OR with NULL

try:

<?php
if($_POST['subemail']==\"\") {
header (\"Location: noemail.htm\");
}
?>

and don't forget to put quotes around method="POST"
