Keep in mind that cookies are set by sending an HTTP header as part of the response, so until you do that they can't be sent back to you by the client (and subsequently appear in $_COOKIE). > (I assume that I can set several cookies using successive calls to setcookie()?)

You can also use sessions by putting the session ID on the URL, but this, I believe, is called "a ball ache". -- Richard Heyes HTML5 canvas graphing: RGraph - http://www.rgraph.net (updated 16th January) Follow me on Twitter: http://twitter.com/_rgraph Lots of PHP and Javascript code - http://www.phpguru.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
