Real "read/not read" threads and "new messages in forum" highlighting v1.2

Hello all!

It is just a vb3 version of old hack
https://vborg.vbsupport.ru/showthread.php?t=47101
And with same weak sides.

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 profile) 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 (if there are new posts since your last visit of that thread)
-one additional SELECT (of 2 fields only) for each subforum on forumdisplay.php
-one additional SELECT (of 2 fields only) for each forum on index.php
-one addditional UPDATE in newreply.php
-"mark forum read" works using one extra UPDATE
-and "mark all forums read" using 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 thread in each forum and if it found, display that there were no new posts in that forum.

Additionally read\unread marking can be time based (new field ) "marktime" in users custom fields. 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 profile settings.
And at last to mark forum (or all forums) read we just mark read last thread in that forum (or in all forums

History:
v.1.2
Fixed moved threads highlighting.
some changes in functions.php and functions_forumdisplay.php

v.1.1
Fixed SQL request. If you tried to install v 1.0 already, better drop view field
ALTER TABLE `thread` DROP `view`
and recreate it again
ALTER TABLE `thread` ADD `view` TEXT NOT NULL

Sorry for my English and please ask questions if you don't understand something

Doesn't work. Nothing is marked as read

I tested it with a fresh vB3 gold installation. Not even forumdisplay.php?do=markread works properly

I have to users, each made 2 threads. 2 threads (made by user 1) have '1 2' in the database and the other 2 (made by user 2) have 'null' in the database.

The first 2 threads are marked as read.

search.php?do=getnew doesn't find any threads but there are 2 marked as unread

Sorry, but I just checked and rechecked everything 3 times on fresh forums and found nothing wrong except line numbers for search.php
So just now i can suggest only checking scripts changes again
Uploading fixed txt with correct line numbers ans visual framed HTML example of changes in two longest scripts (but that examples for this hack together with fulltext search hack - sorry
Is there somebody why saw it working after installing ?

Yes, especially the 'new messages in forum" highlighting ' I would like to see in action.
This sounds to me like a feature I know from my old UBBT.
