I've been struggling to wrap my head around itfor about a week now.My goal is to create a simple threaded discussion board (nothing asadvanced as the Pubb or other professional solution). Right now I'm justat the level of trying to understand how the data should be set up inthe database, and how to do a search that will show the threads in theirproper place all at once.I've been able to create what kind of looks right, but I'm not surewhere I've gone wrong. The html page I search on shows the first twolevels the way it's supposed to, like this:forum level main1 main2Forum level2Below the main1 and main2 levels all the records just cascade down, oneright after another as if they were all replies to the message beforeit. Like this:Forum level main1 reply to main1 reply to reply of main1 A second reply to main1 (this should be in the found itemsof the first reply to main 1 but it's not)Would someone with the proper knowledge look over what I've done and letme know what I need to do?I'm using webcat 3 on webstar 4.XHere's the database I'm using with mocked up entries. The field namesmight be technically wrong, so I apologize in advance if they misleadanyone. That's one of the things that I'm confused about.Forumid threadid replyid msgid childid subject msgdate1 2 3 mainlevel 06/01/20031 3 2 5 6 first level 06/05/20031 5 7 8 2 second level 06/07/20031 3 9 10 2 first level 2 06/08/20031 8 12 13 2 third level 06/09/20031 14 15 mainlevel2 06/08/20031 10 16 17 9 reply to first level 206/09/20031 3 18 19 20 first level3 06/10/20031 13 21 22 2 fourth level 06/11/20031 22 23 24 2 fifth level 06/12/20031 8 25 26 2 third level2 06/10/20031 13 27 28 2 fourth Level 2 06/15/2003Here's my code on the page that I want to search all the records andshow the threads in their proper place.
