=V.2= vB3 Similar Threads

vB3 Similar Threads =Version 2=
by Velocd

This hack, as well all my other vB2 hacks, I no longer provide support for (being I run vB3 and it's too much hassel to debug vB2). When vB3 Release Candidate comes out, by request I might convert some of my hacks.


Update - Version 2.1
View this post (https://vborg.vbsupport.ru/showthread.php?postid=333346#post333346) for complete information.


Description:

I recoded the old vB3 Similar Threads hack earlier today, realizing a much better and enhanced method of making it work.
Also, I made a new thread for this hack mainly so it would be better known, since the old one had many unsolved issues.

Improvements:

It no longer compares threads via a similarity or priority level, but rather using a MySQL string-comparison function.
I experienced no slow downs on any pages, and many of my pages seem to be generating .20 faster (from the old version).
The comparison between threads is even more accurate and efficient, and best of all requires no toggling of a priority setting like the previous version. The threads are now searched via the one and only query, making things faster. ;)
The hack has been tested on 2.2.6 and 2.2.9, and also does not require the use of PHP function trim(), so older versions of PHP should deal no trouble.
The overall appearance of the hack has been enhanced to look more vB3 as well :p


The MySQL function MATCH..AGAINST requires MySQL version 3.23.23 or later, else the hack will not operate.

Screenshots:

Refer to the .zip, they are located inside. ;)


Upgrading?

If you are upgrading from the old version, just replace the codechunk.txt file in the location of the old chunk, as well replacing the templates.

---------------

Remember, if you use this hack on your forum, please click the install button! ^__^

side note: once installed, the similar-thread box will not show until you start replying to threads or create new ones. I predict this has something to do with the altering of the field title to FULLTEXT

side note 2: if for some reason you are getting an error about FULLTEXT not being functionable on your thread table, you are running a non-MyISAM table type, and thus must be converted. Run this query to do so:

ALTER TABLE `thread` TYPE = MYISAM

[ZiRu$]

Nice....i dont hack my board any more though....

[Boofo]

In the install file for this hack, you said to do this:

c. Modify the values "$limit" and "$type" to your preference.

There is no $type variable to change. :)

[Boofo]

Also, I replied to a thread, but no Similar thread box showed up. Will it only show "New" threads that are similar, or will it pick up the old ones once the threads are created or replied to?

EDIT: I got it working. I had to put the code under "Show Threads" instead of "Show Posts", like you have in your install file. :) Is there a way to get the last poster to list also?

[TheComputerGuy]

Thanks for making a better hack!!

[Chris M]

Thanks:)

[TECK]

With your hack, you will display all private forum threads, if they match the text. You need to use perms for this in order to make it efficient.
I install it, but heavily modified based on forum perms. ;)

Here it is the code I used:
$similarthreads = '';
$similarthreadbits = '';
$threadscount = 0;
$forumperms = $DB_site->query("
SELECT forumid,canview
FROM forumpermission
WHERE usergroupid=$bbuserinfo[usergroupid]
");
while ( $forumperm = $DB_site->fetch_array( $forumperms ) )
{
$ipermcache["$forumperm[forumid]"] = $forumperm;
}
$DB_site->free_result( $forumperms );
unset( $forumperm );
$getforums = $DB_site->query("
SELECT forumid,parentid,displayorder
FROM forum
WHERE displayorder<>0 AND active=1
ORDER BY parentid,displayorder
");
while ( $getforum = $DB_site->fetch_array( $getforums ) )
{
$iforumcache["$getforum[parentid]"]["$getforum[displayorder]"]["$getforum[forumid]"] = $getforum;
if ( !isset( $ipermcache["$getforum[forumid]"]['canview'] ) )
{
$iforumperms[] = $getforum['forumid'];
}
}
$DB_site->free_result( $getforums );
unset( $getforum );
if ( !empty( $iforumperms ) )
{
$iforumperms = 'AND thread.forumid IN( ' . implode( ',' , $iforumperms ) . ' )';
}
$otherthreads = $DB_site->query("
SELECT thread.threadid,thread.forumid,thread.title,thread .replycount,thread.postusername,forum.title as forumtitle
FROM thread
LEFT JOIN forum ON( forum.forumid=thread.forumid )
WHERE MATCH( thread.title ) AGAINST( '" . addslashes( $thread['title'] ) . "' )
AND thread.visible=1
AND thread.open<>10
AND thread.threadid<>$thread[threadid] $iforumperms
ORDER BY dateline DESC LIMIT 5
");
while ( $otherthread = $DB_site->fetch_array( $otherthreads ) )
{
$threadscount++;
eval( '$similarthreadbits .= "' . gettemplate( 'showthread_similarthreadbit' ) . '";' );
}
if ( !empty( $threadscount ) )
{
eval( '$similarthreads = "' . gettemplate( 'showthread_similarthreads' ) . '";' );
}
Feel free to use it in your install file. :)
BTW, thanks for a great hack!

Why?

[xxxsaint]

nice hack - I won't be installing it though.

[Velocd]

Heh, thanks for providing that Teck, I had figured another way to do it but a bit tacky and lazy on my part ;)


$discluded = "2,3";

then using..
AND thread.forumid NOT IN ($discluded)

I've also updated it with your request Boofo, but I'll add Tecks' add-on first then post the revised version. :p

[Velocd]

Alright, the .zip has been updated with version 2.1.

Updated:
+ Added permission check, with thanks going to Teck for supplying the code. ;)
+ Enhanced "last poster" information, requested by Boofo
+ Updated screenshot

To upgrade from V2:

Just update the template1.txt and the codechunk.txt over the previous code.

Why?

What version of MySQL & vBulletin are you running?

[TECK]

* TECK clicked Install :p :D
Btw, the perms will add 2 queries, for a total of 3. But is better then editing every time the showthread.php, once you change the perm settings.

[Velocd]

What about your vBulletin version? This hack has been tested on 2.2.6 and 2.2.9, thus suggesting it should work for 2.2.7 and 2.2.8 as well. If there are issues with older versions, I'll need to modify the vB database info of this hack.

Same error...
Maybe I must check my thread table.

[TECK]

Hmm, it looks like your table is not set as MyISAM? Only the MyISAM table type supports FULLTEXT indexes...
Are you sure about the MySQL ver?

[XIanX]

I installed the hack and it seems to work fine on my forum except one thing. My forum jump stopped working! See for yourself, http://forums.zforcenetwork.com/showthread.php?s=&postid=10111#post10111

[TECK]

Heh, is my perms that kill it... I will post a fix... I don't use forumJump because it saves me 2 queries. :p

Indeed, you are correct about that. It may be something to do with variable conflict, I'll check it out ;)

[TECK]

Velocd, I'll let you have fun. :)
Look at the function makeforumjump().

Guys, just disable the forumJump it will save you 2 queries all over the board... who use it anyway to navigate? Nobody.

My thread table is ISAM.
Thanks.

[XIanX]

I've disabled my forumjump for the time eing. :bunny:

[Velocd]

I was at first pondering if there was a way to combine the forum permissions in forum jump function with that of this hack, but then after reading your post Teck it dawned on me that I never do use the forum jump..and it is quite useless.. :p (another 2 queries saved.. ^_^)

If you wanna solve your problem still Xianx, place the code in codechunk.txt under makeforumjump(), and that should do it.

[TECK]

Just unset $iforumcache and $ipermcache, that should do it... if you really want to have both sets of queries... But I find it useless, IMO. Just kill the forumJump. :)

[Velocd]

xware, back up your database just incase of any freak errors occur, and then run this query to convert to MyISAM:


ALTER TABLE `thread` TYPE = MYISAM

Works well now.
Thank you!

This isn't true for me, it works fine after updating from your old version without any new posts being made :)

I've changed:

ORDER BY dateline

to:

ORDER BY dateline DESC

This way I get the most recent matches as oposed to the oldest matches ;) (IMO seems more sensible that way).

* NTLDR clicks install :D

[Boofo]

The line you changed was already in the version I downloaded last night. Is there another version out?

When I put the code in the old spot (from the first version) it also worked without having to update anything. I could never get it to work under the "Show Posts" area, only under the "Show Threads" area. Could that have something to do with it?

[Velocd]

It's not suppose to go under the "Show Posts" area, this hack is meant to show when viewing a thread, therefore it goes in the "show threads" area. Check the new version and its more clear in the instructions now.

In the original version I did have your suggestion NTLDR, but for some reason took it out upgrading. It has been re-added. ;)

[Boofo]

I couldn't find the line in the "Show Threads" section (it was only in the "Show Posts" section for me) to add the codechunk to so I added it ABOVE this piece of code (like you had in your release of the first version):

if ($noshutdownfunc) {
$DB_site->query("UPDATE thread SET views=views+1 WHERE threadid='$threadid'");
} else {
$shutdownqueries[]="UPDATE LOW_PRIORITY thread SET views=views+1 WHERE threadid='$threadid'";
}

if ($bbuserinfo[cookieuser]) {
set_bbarraycookie('threadview', $threadid, time());
}

That might make it easier for everyone to find. :)

Also, I do not have a "$discluded" variable to set at all in the codechunk file.

[Boofo]

Ok, another problem. I lost the forums listing in the forumjump now. When you view a thread, they are no longer there. They are there when viewing a forum, though. Any idea on how to fix this?

[Bison]

For some reason, this version doesn't work as good as the last one ... I get all sorts of thread title matches that don't have any simularities!

What thread titles is this version trying to read? Cause it aint reading them right!

[revert to original in a hurry!]

[Boofo]

Rolodex, try putting the chunkcode above this line and see if that helps. It fixed my forumjump problem and the threads are only showing similar threads if they really ARE similar. Let me know if it works for you.

eval("dooutput(\"".gettemplate("showthread")."\");");

[Velocd]

It's much more accurate for me, not to mention the pages load way faster ^________^

Boofo, refer to the 2nd page about your problem with the forum jump, that issue was already brought up.

[Boofo]

Ok, I see. Sorry I missed that. :) But where I have it now, it seems to be a lot more accurate. It is supposed to pick words out of the title and use those, right? Well, now it does that even better. Any word in the title and it pulls up a Similar thread with the same word in it. Isn't that how it is supposed to work? And will it be alright where I have it now or will it mess with anything, do you know? :)

[Auero]

=/ Okay, it's not working at all for me. I've followed the install file exactly and I still cant get anything to display....????

[Velocd]

@boofo: you're fine ;)

@auero: Make sure you have placed the variable $similarthreads in your showthread template.

Give me a link to your forums, and I'll check it out if it is still not working.

[ptm]

Whew!!! :D :D Got it working perfectly. :)

So far, so good ... but occassionally when I click on a thread link the page comes up blank. I have to refresh the page or click on the back button to get the pages back ... yikes!

[Velocd]

I just realized a good fix for this hack, to make it more accurate. I noticed with the first version I had it check for similar threads only in the forum which the thread originated in. If you do this with this hack, you get much more valid results, mostly if you have a large forum.

I've updated the instructions to include this, so just re-upgrade the codechunk.txt.

If you want to just do it manually, find (in the codechunk):

AND thread.visible=1


And replace it with:

AND thread.visible=1 AND thread.forumid=$thread[forumid]

[Velocd]

Actually.. I just realized that if this is done, the displaying of which forum the similar thread is in is pointless.

Although, I just got another good idea: Search the parent forum and all sub-forums within for similar threads, that the thread originates from.

Now if I can only figure out how to do this.... ;)

[NTLDR]

A note on the permissions for this hack. They only work if custom permissions are applied to all forums (which have different permissions) as it ignores inherited permissions. I've had to disable this hack now till they work correctly.

[Bison]

Another question ... why are you pointing the category background in your showthread_simularthreads template to:

<tr align="center" bgcolor="#336D95" background="https://vborg.vbsupport.ru/images/catagory_backing.gif" background="https://vborg.vbsupport.ru/images/catagory_backing.gif">

Is there a reason for this, or are you "unknowingly" duplicating the same mistake in every update of this hack?

[Velocd]

It's only one small mistake Rolodex, nobody is perfect, eh? I'm quite lazy as it is, so I'll update it next time I figure it need be. If it's gonna kill you, then well.. I bid you the best farewell ;) j/k

@NTLDR: When you say inherited permissions, do you mean specific permissions geared to user groups? Also, can you give an example of how it is not working? I have user group and forum permissions set, and this hack is working correctly--unless I am overlooking something.

[Schorsch]

thanks!! very nice modification :)

Because he wanted to see if you are checking everything and not install it no matter how.

Velocd, I will recommend your hack as HOTM. :)
Is one of the very few hacks I installed from many out there...

A small recomandation, try to use into the templates the direct variables pulled from the fetched array. No need to redefine them again inside. Look at my code example (permissions)...

Also, for NTLDR, the perms code listed few posts above are set based on my forum settings. I don't use access masks to save a query on all pages (everyone should do the same!!!) So yes, the perms will not be inherited.
Disable the masks, set your perms individually, or even better, write your own set of perms if you want an extra query on showthread.php file (for a total of 4, instead of 3, as it has now the hack). ;)

[Velocd]

Thanks for the comments and suggestion, Teck ;)

I've updated the .zip once again, fixing some minor stuff :p

[DrkFusion]

Great Hack, I installed the first one, I will install this one.

It's not a point of it killing me dude, it just looked like you should have noticed this after the second update ... that's all.

And TECK, you have a way of budding in on sh*t that makes you look even more like the jerk you really are ... sometimes it best to shut the f*ck up when the attention is NOT pointed @ you!

[TECK]

Rolodex, is the way you posted acting like the smart ass. Instead of being normal and posting the error, like:
"Velocd, I noticed this error, I think it should be this way, not this way..."
you decided to show your "superiority".
My example, listed 2 lines above, is a constructive way to correct an issue, not your way, but you cannot realize this.
This guy Velocd made a great addition to vBulletin and instead of being nice and modest you act like the HTML wizo, when is such a small mistake.

Hey, I make those kind of HTML mistakes every day, I'm not as perfect as you are and "I don't notice everything" because, as Velocd said, I'm human. Making a good piece of code (like Velocd's) is alot more important in my eyes then a small template editing typo. I was looking for a solution like this and he made it easy for me because I didn't know I could run a query like the one he wrote... so I also helped him with the perms to make this hack a really good one.
You are right about one thing, I shouldn't waste my time posting to those kind of people like you.

[TheComputerGuy]

I use the Forum Jump, and tried to do what you said to do on page 2...yet..my forumjump still does not show properly...any ideas...

[TECK]

Place the code just about the eval(); and unset the perm and forum cache:
unset( $iforumcache );
unset( $ipermcache );

// Velocd's code here...

eval("dooutput(\"".gettemplate("showthread")."\");");
It should take care of the problem.

[DrkFusion]

Thanks teck, I was having the same error.

Example Structure:

-Catagory
--Forum 1

If I set the canview permission for Catagory to no for a usergroup, when using the forum that usergroup cannot see Forum 1, however threads in Forum 1 will still show up as similar threads even if though they can't access the thread.

[TECK]

Lee, is normal. I explained to you where is the prob few posts above.
Get on my board for the fix, if you really really want to use access masks (it will add another query). :)

[NTLDR]

I did try what I thought would account for access masks but it didn't work, probablt the code I used was wrong. I'll take a look at TW.com now, thanks for the info TECK :)

[TECK]

Set perms individually for each forum. A little longer in the procedure but it will save you a precious query.

Heh, I didn't know also. Chen was kind to show me a trick, is pretty complex (at least for me) :D

[NTLDR]

I have to agree the permissions is one of the harder things to accomplish ;)

Have you got a link for the code as I couldn't find it at TW.com.

[TECK]

I will post it in there later on after I test it properly... :)

[sparky2]

Slick hack, but I'd prefer a LINK ~~ rather than assuming each user wants to "view similar threads" every showthread.php page view.

Also, it seems like this hack is a LOT of work just to duplicate functionality that's already built into search.php
(select a subforum // search in titles only )

In showthread.php, you might want (need) to check $searchenabled and $cansearch values
and conditionally null the template if search isn't currently enabled...

but piping it to search.php would take care of:
-- PARENT/sibling title searches
-- permissions
-- runs the title text through BADWORDS

In other words, I'm suggesting that you try this approach:

Create a link to search.php (essentially, a submit button)
& pass post['title'] and forumid as hidden fields
(user sees nothing other than a button, or link, labeled "find similar threads")

[boatdesign]

What are the minimum PHP version and MySQL version requirements for this hack to run? Does it still require PHP 4.1 or will it run on 4.0.6?

[TheComputerGuy]

TECK, thanks for offering what you did, but it doesn't work properly, I tried to uninstall the hack and my forum jump does not work :(

[TECK]

Ok, I enabled the forumJump just for you. I will take it off tomorrow...
Use tester/test to login onto my board and see that it's working. :D

View this forum, for example:
http://www.teckwizards.com/forum/forumdisplay.php?forumid=5

[Velocd]

@sparky2: yeah, that is certainly possible, but that would cancel out the purpose of this hack being named as "vB3 Similar Threads," as it is suppose to visually look and function like the vB3 feature over at vBulletin.com. Despite the fact that I use a mySQL function MATCH..AGAINST which is probably not as efficient compared to the method Freddie used, which he explained here (https://vborg.vbsupport.ru/showthread.php?postid=286453#post286453), but oh well.... this version works well enough for me. :p

Feel free to make that request yourself, as it surely isn't difficult to do. ;)

[TECK]

Well, in VB2 the word table is not indexed... and I think that Freddie used there several LEFT JOIN's which also affect the performance...

[TheComputerGuy]

TECK, you da man as usual, I will retry on a clean showthread file. Your recommendation for where to place it...Do i place chunk.txt right above the last line? I believe that is the part I got confused on

Thank you so much for helping me.

Notice the // Velocd's code here... part? Replace that line with the chunkcode (that makes me think of biscuits, heh)...

[sparky2]

Huh???

run this query:
show create table word

and you'll see that both (of the 2) columns are indexed

[Velocd]

Actually it might vary from version sparky2, as both of my columns in the word table are not indexed ;) (running on 2.2.6)

It's not that significant anyway :p

[VirtueTech]

It appears "freddie" was right that this was not the most optimized way to go about "similar threads".

Check out the delay! :(

Nice try though. I was excited that you had made this hack...too bad I can't use it. Thanks anyway.

[Velocd]

Ah yes, but I could defiantly understand why with your forums VirtueTechy--they're massive :p

Then again, this version of the hack is more improved from the last, in the major effect that it will compare threads to the current thread viewing until it has gathered whatever you set as "LIMIT", in your case 4. (in contrast to the old version where it would retrieve ALL threads, then compare). Not to mention, your forum must have dozens of threads with similar titles, so this hack shouldn't have a problem finding 4 similar threads and quickly. Then again, each similar thread could be seperated by 300 non-similar threads, thus having to read more.

This hack still proves very useful for the smaller forums, such as mine with 1,938 threads and not the slightest decrease in performance. ;)

[Velocd]

I just thought of some suggestions that could be done, if you are up to hacking yourself, otherwise I might think of implementing this later. You could either do what Spark2 suggested here (https://vborg.vbsupport.ru/showthread.php?postid=334382#post334382), or make it appear in a small pop-up window. To do this create a seperate PHP file known as similarthread.php, then inside contain all the data of codechunk.txt, but at the top of the file insuring that global.php is being required, error-reporting enabled, and surrounding the file by the php open and close tags. Then in the template that contains template2.txt, put the html, $header, $headerinlcude, body, and other basic tags in it. Then in the showthread.php, make a link appearing like this:
<a href="#" onClick="window.open('similarthread.php?s=&threadtitle=$thread[title]','javascript_1','width=x,height=y,scrollbars=1,re sizable=no,menubar=no,toolbar=no'); return false;"><u>Click to view similar threads</u></a>


Just configure the "width" and "height" attributes, and also whatever you want to use as a link caption (whether it be text or image).

Also in similarthread.php, change the variable "$thread['title']" in the query WHERE clause to $threadtitle (not sure if arrays can be passed through URL's)

This method at least it gives the users their option of viewing the similar threads, but doesn't decrease the output speed of the thread. ;)

[VirtueTech]

Not a bad thought. Just to let you know I wasn't trying to down this hack. You did a wonderful job. I was just making you all aware of the problem large forums like myself would have.

Thanks for the alternative Spark2 and Velocd! :)

Thats because you have like 20 forums. I have over 190. On top of that there is over 1.4 million posts. Thus the delay in going through the titles even though it is indexed. Also the reason why "freddie" used the method he did in vb3

[ChurchMedia]

I'm getting this error:

Fatal error: [] operator not supported for strings in /home/virtual/site6/fst/var/www/html/community/forum/showthread.php on line 500

[X-Fan]

Great hack, thanks!

I was experiencing some slowness as well, so I tried to come up with a way to limit this feature to only selected forums.

Basically, at the start of the codechunk.txt, put this...


if ($curforumid==2 or $curforumid==3 or $curforumid==4) {
$similarforum = "2,3,4"; //Limit search to these forums


...replacing the curforumid numbers with whatever forums you want to have include this feature, and the similarforum numbers to whatever forums you want the feature to search for matches.

At the end of codechunk.txt put this:


}


Now delete everything from...


$forumperms = $DB_site->query("


...down to:


$iforumperms = 'AND thread.forumid IN( ' . implode( ',' , $iforumperms ) . ' )';
}


As its unnecessary to check forum permissions when you're specifying what forums to find matches in.

Now, find this line:


WHERE thread.threadid<>$thread[threadid] $iforumperms


And replace it with this:


WHERE thread.threadid<>$thread[threadid]


Then find:


AND thread.visible=1


And after that add:


AND thread.forumid IN ($similarforum)


To only allow the hack to search for similar threads in those specified forums. However, it's still pretty slow for me, so I'm thinking something's not working right.

Any help would be greatly appreciated! :)

[X-Fan]

Also, another question - is there a way to omit specific words from the matching process? Or perhaps a way to add keywords to threads and allow matching to those?

I'm just trying to find a way for the matching process to be more accurate on my forums, as currently it's not overly accurate.

You are right. I tested this on a huge board also... and is slow, unfortunatelly.

[maestrosdelweb]

Great hack.

I'm installing it right now.

[Erwin]

Mmm... I am using version 1 of this hack, and it is working well on a reasonably sized forum (half a million posts). Should I upgrade? I am loathed to since everything is working fine.

[Gutspiller]

I installed this hack and it works great with my forum! :banana:

I have one question though. The way that it works, I take it it does a type of search for these "similar threads" I want to change the way it works and make it more precise by only searching the titles and not the contents of the threads. This way it wont matter the contents of the post is, the similarity will have to occur in the title of the threads.

Can somebody help me how to do this? It should be fairly easy, I just have any clue. :(

Please help.

[Elvis]

I'd strongly suggest replacing:


ORDER BY dateline DESC


with


ORDER BY threadid DESC


on a board that dates back a couple years worth of posts... this seems to help show only the most recent 'similar threads'

[Boofo]

All that will do is display it in order by tread title instead of order by date. I think it only looks at the thread title for matches already, doesn't it? ;)

[Elvis]

a) by 'threadid DESC' it orders the found threads in descensing thread ID order... which gives you the most recent threads, in order that they have been started, not replied to. It's much more relevant to pull up things from this year.. than say 2001.


b) Yes, but Im not changing WHAT it searches, just how it orders them.

[Gutspiller]

Can somebody still help me with my first question? I want it so that the way it ranks similar threads is done by thread title alone and not by the contents of the thread. The way my forum is setup the current searching isn't as good as if it was based on the title of the thread alone.

Anybody? :(

[Boofo]

That's how it already searches.

[Gutspiller]

Originally posted by Boofo

Well how about making the words that are before each other more important that the following words.

So a title that is "Unreal II movie"

wont bring up similar threads, just because their title has the word "movie" in it. Movie isn't going to be important. But other titles that have "Unreal" are going to be more important .

Can you do that?

[Boofo]

It should bring up anything that has "movie" or "Unreal" in it. And even "II". I have mine set to show 10 threads instead of the default 5. Maybe that will help? It would be kind of hard to selectively pick the order of words in the title, I think.

It would be kind of hard to selectively pick the order of words in the title, I think. OK, I changed it to 10 and out of those ten threads, only 2 reffer to Unreal or Unreal 2. Is it possible to have it use the first words of the title? I mean movie could be anynumber of threads. Most threads are going to have the important words first. So I was hoping something could be done about having it more relative to the other words. This way the closer they are to the beginning of the thread title, the higher ranking they have in the search. Is something like this possible?

I was also noticing that the previous version of this hack supported descriptions, but I didn't happen to notice anywhere in the code to turn that feature on. Is it in there and I missed it or does V2 not support descriptions?

[Xyphen]

Ok, I have a test forum, where there are only 2 threads -_- so far, but the smiliar threads thing doesn't show up on showthread? why, help please, I am using vb2.2.9, there are no errors, just that smiliar threads don't show up, nothing shows up, everything is exactly the same as it was before i installed the hack, I even replied in both threads and made a new thread, doesn't work at all. help plz..

[andyrose]

I installed this hack at www.neomega.net/forum, and it works like a charm. Excellent job.

[FleaBag]

OK I'm having a problem with the hack...

As you can see here (http://dragonninja.co.uk/showthread.php?s=&threadid=2677), the table for the similar threads is created, but theres no links or information in it. As far as I know everything is installed and working correctly - I had this installed on 2.2.8, but now I've upgraded to 2.3.0 it doesn't work. Any help would be appreciated, thanks.

I don;t get any error messages and everything appears to be working fine
But when i post a new thread nothing shows up under neath - Tell me I am doing something simple?

Does this work with the current stable release of vB 2.3.0 ??

I have downloaded this and would like to install !

Thank much

[AlexanderT]

it works in 2.3.0.

[Mireade]

Very great hack !

What about putting this kind of possibility on a non vb page ?
Would it be difficult ?

And another suggestion to make it more "server friendly" :

Would it be possible to have just a link on which the user could click to get the related threads (so the query would not be systematic but just on demand) ?

Thank you

[ChurchMedia]

I'm really looking forward to getting this to work. I'm getting this error, however:

Edit:
I have the obligitory $similarthreads in the showthread template, but this generates nothing.

Sorted, started with a clean showthread.php file.

Thanks.

This is wierd. I had it working. Made no further changes. Come to check the site 2 hours later and it's not showing again!!!

I'm the only person editing the site. All files are unchanged.

I've checked everything again, but no joy. This is being a right pain in the rear!

Oh look, it fixed itself! Some wierd stuff going on with this hack

[Ninth Dimension]

nice hack, i've just installed it, but like many other people i've seen in this thread i can't get it to show any info. I believe that might be partly due to the forum having very few posts on it (i.e. it's a production site) but i'm making threads with similar titles and content in a bid to get it to show up and t's not doing anything.

can someone point me in the right direction? thanx.

It's OK fella, i've got it working now, I was only using half the code needed, thank you very much, this add's an extra dimension to the forum :)

Hello Folks...

I love this hack, it´s great...

But there is an interesting problem with the permissions. For my registered members, it´s all okay, but UNregistered people can see all threads including the internal ones...

Velocd kinda explained this earlier in the thread for what he used to exclude private forums... I used it to exclude newsgroup forums.

In the top of codeblock put:
$discluded = "50,60,70";
where the numbers are the forumid's that you want to exclude

after
WHERE thread.threadid<>$thread[threadid] $iforumperms
put:
