Keep a table of "notifications" and what time they happened, and if the user has seen them -- perhaps even allowing the user to choose which ones to dismiss, perhaps even only having a little icon about notifications if there are any... When the users hits a page, check the notifications table for things they ought to know about. The exact rules of how/when to do what is up to you and your users, but give it a lot of thought before you go annoying the [bleep] out of users with a damn popup for each notification stacked up or something... :-) This takes a lot more thought about WHAT to do from a process/user-interface side than HOW to code it in PHP. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
