You could use AJAX to get things from/to PHP, but why should you? You can use session within javascript too i believe.

In the next version of my framework i would like to, i still havent quite understood the whole concept, not enough research yet, but yes i'll be doing that next ;) (you know deadlines, can't sit and read docs all day etc.. Although i'd rather!) ;) Regards, Tim
Really, it's not that hard to use AJAX. You might want to look at www.tizag.com, there it is really easy explained. It's nothing more then making new request to scripts inside javascript. Tijnema
