Steve,
Here's a snippet from the PHP manual:
"Once the cookies have been set, they can be accessed on the next page load with
the $_COOKIE or $HTTP_COOKIE_VARS arrays."
All you dowith setcookie() is sending a cookie to the browser. This doesn't mean
the value is also stored in the $_COOKIE array at that time. That doesn't happen
until the next request when the server receives back the cookie from the
browser. That's why when you refresh the page everything seems to be suddenly
working.
What are you trying to achieve by setting the cookie in the edit_user.php script
if you want to use that data in the same page anyway? The data is already
available to your script from the $_REQUEST array (and, in this case, from the
$_GET array).
