Real "read/not read" threads and "new messages in forum" highlighting 1.1
Developer Last Online: Apr 2014 
Hello !
Think that i finished testing and optimizing beta hack from https://vborg.vbsupport.ru/showthrea...threadid=47035  Features: - Thread on forumdisplay highlighted for user as read only if that user saw last post in that thread or if last post in that thread is older then user defined (from user CP options) amount of time (from 1 to 999 hours and infinity) - Forums on index page and subforums on forumdisplay pages will be highlited as "have no new posts" only if user saw last post in that forum or subforum - Highliting system is completly cookie-free - System will require extra Database space (2-4% on large forums and 5-6% on small) - Sytem will add some extra queries to scripts -one addditional UPDATE is showthread.php -one additional SELECT (of 2 fields only) for each subforum on forumdisplay.php -one addditional UPDATE in newthread.php -two addditional UPDATE in newreply.php -"mark forum read" works using one extra SELECT and one extra UPDATE -and "mark all forums read" using one extra SELECT and one extra UPDATE for each forum Few words how it works As you know vb "marking threads and posts read" system is time and cookie based. This hack is based on adding to "thread" table one extra field - "view" (suppose that it must work fine with TEXT type, but for really large forums we can make it LONGTEXT Now when somebody open thread, his usedid will be added to that "view". After several users (who open that thread) string in that field may look like 37 298 16879 7287 29087 28 298 So it will be just a long string with userid-s separated by space Now then user open forumdisplay.php script will check string in that view field of each thread for part of string [space userid space] and if is will be found thread will be marked as read. If you think that it will use too much database space, i can say that it will use some place of course, but not too much, because after each reply in thread (new last post in thread) all old data in "view" field of thread will be deleted. On forum home page script looks for userid number in "view" field of last post in each forum and if it found, display that there were no new posts in that forum. To make it work faster (with less database requests) was added new "view" field in thread table Additionally read\unread marking can be time based (new field ) "marktime" in users table. And users are able to select number of hours (all posts older then that number of hours will be marked as read) in their CP options. And at last to mark forum (or all forums) read we just mark read last thread in that forum (or in all forums Sorry for my English and please ask questions if you don't understand something Show Your Support

Nice hack but one extremely large problem here!
My site when from 28 queries on the home page to 49!!! I love what it does but I'd like to keep my server healthy.

Hello !

It ads one additional query per forum on index.php...Sorry, but it is a pay I am still thinking at optimizing...But only index.php is so large problem. On all other pages it is not too heavy and you may not change index.php at all and leave it without real highlighting. After it "not read messages" on forumdisplay.php and search.php will be still real

Has anyone installed this on the new vb3 gold version? any problems / does it work?. And for a newbie when it mentions commenting lines of post then adding new after the comment, is it just basically adding whatever is mentioned after what to find/ hope this made sense !
