How To...

Hi All
I am writing some 'contact me' code for my web page and need some help with
the following code snipet below:

$validated ="Yes"; //declared early in the code, and I got some other error
//checking

if (strlen($message) > 128){
$validated = "No";
}

//some other stuff I won't bore you with

if ($validated == "Yes"){
mail($to, $subject, $body);
echo "Thanks for you message!";
}
else {
// I need something like:
header("Location: http://$site_url");
// BUT I don't want to type the full url, I want to go back
to the //previous page and I want it to work
when I use it on
// my other web site in a different directory so,
//www.myexampleblahblah.com/form.php
// is not ideal - How can I do it?
}
Many thanks, G

I always declare some config data first - the full url, the dir where
scripts reside, DB connection details,... If you do that then you can use
it everywhere.

Of course, you have to set it up when you upload to a new server.

Hope it helps.
