Can't validate form

pmoore · June 3, 2008

This started out as a tell a friend script to add one friend and I've added the variables $FriendName1, $FriendName2, $FriendEmail1, and $FriendEmail2. I'm close to modifying it to suit my needs (send to up to three friends) but when I submit the form it gives an error:

"- FriendName1 must contain a number"

I'm sure it will happen for FriendName2 as well, and I'm stuck. Here's the entire code:


<?php

$FriendName = $_POST['FriendName'];
$FriendName1 = $_POST['FriendName1'];
$FriendName2 = $_POST['FriendName2'];
$FriendEmail = $_POST['FriendEmail'];
$FriendEmail1 = $_POST['FriendEmail1'];
$FriendEmail2 = $_POST['FriendEmail2'];
$Name = $_POST['Name'];
$Email = $_POST['Email'];
$emailtext = $_POST['emailtext'];
$string = $_SERVER['QUERY_STRING'];

?>

I'm pretty sure that this is the line giving me trouble:

<form name="form1" onsubmit="MM_validateForm('Name','','R','Email','','RisEmail','FriendName','','R','FriendEmail','','RisEmail','FriendName1','','val','FriendName2','FriendEmail1','','isEmail','FriendEmail2','','isEmail');return document.MM_returnValue" action="" method="POST">

I'm just not sure what to do from here. I've been at it for a while. Searched for form validating, MM_validateForm, etc... and I'm just lost. I'm new to all this but try to do stuff myself.

I appreciate any help!
