Just started today with php, integrating it into my site. I found a email script and actually got it to work! If the user fails to fill in one of the data sets and trys to submit, an error msg pops up telling them what to fill in.
The script uses "die" and then the "message". I would like to change the "die" to "go get" a specific page from my site?
I'll keeping looking for the info, but if you know, I would sure be thankful!

Lots of ways to do this depending on your script:
code an include instead of the die
use header(Location: "http//pagetoget.php")
echo a javascript redirect to the browser
Personally, I use general purpose pages for forms that include validation,
Not submit, then display blank form
Submit, then validate form:
validation error, redisplay with submitted entries and message indicating required field to complete
validated, then display appropriate message
Roger thanks for the reply. Your suggestion is what I was looking for all along. However most examples I found wanted to keep it simple so that understanding was easy. Which it did. I just started my php learning curve yesterday.
Could you provide a sample script of your method and I can then tailor to meet my needs. That would be helpful if possible.
Thanks for the reply and hopefully 2007 will be better. just remember that most of the time the next day isn't as bad as the last!

OK, here is a complete contact page that I knocked up recently. Not the tightest bit of coding cos I did it in a rush as a freebie for a friend. It includes the js for page validation, the php validation in case js is off and the error reporting when that happens. It also refs functions for defending against spam exploits which I've posted at the bottom.
Oh yes, the $vals array is used to store and redisplay user input.
<?php // contact.php
require_once('includes/header_no_session.php');

function EmailChecker() {
if (document.contactform.name.value == ""){
alert("Please enter your Name");
document.contactform.name.focus();
return false;}

alert("Please enter your Company Name");
document.contactform.company.focus();
return false;}
