i want to have php check the number of rows when the page is loaded, then display the rows in descending order, wait 10 seconds, check to see if the number of rows has changed (if there are new messages) then have it either display a pop-up with javascript or refresh the <ul id="wall"></ul> bit... is this even possible? i got the code for the page from here -------------------- If I am helping you and don't reply in 24 hours please send me a PM
Currently in training... There's no place like 127.0.0.1 There are 10 types of people in the world, those that can read binary, and those who can't. |

Yes, it is possible. You need to store the number of messages within the user's session. If the number of threads change, then the server needs to push out the updated page.

What I would recommend is looking at web pages that auto-update and figure out what they are doing. It is not something that anyone can sit down and tell you how to do in 3 minutes. Besides, this sort of functionality should not be part of the core features anyway. This should be considered an enhancement. Get the basic stuff working first.

just to help you anyway even though groovicus is right about it being an enhancement, to do it you could use an iframe with a page which loads the messages and in that page just put in a piece of javascript to refresh the page every 10 secs

You could try looking at how Shoutboxes are created as it seems your using the same sort of functionality..
