e.g.
when the user enters
search="fab widgets"
drop-down="widget.com"
he is taken to....
http://www.example.com/widget.asp?searchtype=allproducts&searchstring=fab+widgets
How do I do this? Do I need to create a PHP script to handle the form?
Thanks, Pete

Any PHP wizards care to try?

header ("location:http:\\www.widget.com");
.....but it's really slow.
Is this a sympton of doing it server side?
Could one of the mods move this to the PHP forum?
Thanks, Pete
There's no reason that redirect should be slow. So I take it you figured out how to use $_GET to break out the search terms and you are redirecting based on those?
All of those steps should be quite fast. It sounds like you're redirecting to a merchant on another server. Could it be the merchant server is slow?

All help is much appreciated.
Thanks, PEte

It's not a $get command, but rather a language feature in PHP. PHP has a set of so-called "super-global" variables. These variables are available anywhere in your script, even inside functions where normally only local variables are available.
One of these is $_GET which contains all parameters sent as part of a query string.
[example.com?q=qword&t=time...]
would yield two get parameters
$_GET['q'] with a value of "qword"
$_GET['t'] with a value of "time"
Sometimes you can access these values like so
$t with a value of "time"
This happens when register_globals [us2.php.net] is on. Generally this is considered sloppy and somewhat dangerous practices. It is not inherently insecure, as many people contend, but it's more a matter of making your code less secure. For example, you can also use the "post" method to pass data. So if I have
$_POST['t']
$_GET['t']
and register globals is on, what is the value of $t?
