something like:
<?
// filename: here.html
if ($submit)
{
$error = false;
if (trim($email) == "")
{
$error = true;
}
// process more...
if (!$error)
{
// do stuff here, maybe a header("location:....");
exit;
}
}
?>
<html>
<form action="here.html" method="post">
<input type="text" name="email" value="<?= $email; ?>">
<input type="submit" name="submit" value="Go For It!!!">
</form>
</html>
not tested but should work - just expand on it

Ya, it would be cool if you could.... how do you submit the form to itself?
Right now, I have something like
if (!$submit) {
display form
}
else {
process
if (trim($email)=="") {
echo "error, hit back button to fix";
}
}
Thanks
Jason
