You might try downloading PHPBB, and examine thier code.

Hi there.

I'm trying to understand the math or 'how it works' with threaded posts and such.

I'm using a MySQL table with like id's, subid, etc..

Can anyone point me in the right direction or give me a brief 'overview' on how it works.

Been getting really confused and need a better way of doing it!

Thanks

Darren

Basically, it's all about trees (a kind of graph). You should find some
general info in any programming theory book. You have a collection of
nodes with a special attribute (pointer, branch... whatever name you
give it) that links them with other nodes. As for a forum, having
"message_id" and "parent_id" is probably enough (root messages will
have a NULL parent_id). As for dealing with trees, the best approach is
using recursive function.

Please note I've never written a forum myself and my theory might be
pretty rusty.

On the subject of trees, I find this package helpful:
