Inserting into table at specific spot

[rwwmatt]

I am trying to setup a message board in PHP, and use MySQL to store the messages. I want each message stored in table as a row. I also have the replys added to the table of the original topic. Anways, whenever a reply is added, it adds it to the end, but I would like a reply to a specific message directly after it. Is there anyway I could easily set it up to where a reply is inserted at a specific location in the table?

Hello,
Forums are constructed on a simple parent-child relationship model. Using one field to store the primary key and another to store a foreign key from a parent post, you can produce list of posts and replies in a classic forum style. Top-level parent posts get a parent_id of 0, while a reply to message 1 would have a parent_id of 1 but a unique id of say, 2.
