[DS] Auto Lock Threads v2.2 BETA
Let's your threads being auto locked after a limited number of posts, or after a Date/Time, or even after some Interval.
Good for games threads, spam threads and event threads.

It is still a BETA release. Feedbacks are welcomed as always.


  1. Upload the DS folder to your XenForo's /library folder (ex: /www/html/forum/library).
  2. Go to ACP -> Add-ons -> Install Add-on -> Install from Uploaded File
  3. Select the addon-DSAutoLockThreads-x-x.xml file
  4. Click Install add-on
  5. Wait for the system to finish installing it

  1. Upload the folder as explained on item 1 of Install procedure, overwritting the files
  2. Go to ACP -> Add-ons -> Auto Lock Threads -> Upgrade -> Upgrade from Uploaded File
  3. Select the addon-DSAutoLockThreads-x-x.xml file
  4. Click Upgrade add-on
  5. Wait for the system to finish upgrading it

PHP 5 >= 5.3 version required for it to work.
Developed using XenForo 1.0.4. Prior versions were NOT tested by me. It may or may not work on them.

On the file name, x-x corresponds to the released version (1.0, 2.0, etc)


  1. Every thread now will show a new link, Auto Lock Options
  2. By clicking on this link, it will open a form overlay, where you can set the limit for the thread.
  3. Input the maximum number of posts allowed, or fill the date/time accordingly, or fill the interval
  4. From ACP -> Applications -> Node Tree -> List Limited Threads, you can check which threads have the auto lock feature, and you can clean the limit any time, clicking on the red X button
  5. That ACP section now have the View thread link, that will open the referred thread in another tab/window, and that is now better organized, filtering threads limited by posts or by date/time
  6. Threads with an Interval will be showed as limited by date/time as well

The Date/Time limit is based on the current SERVER time!! So please test it properly.

It's my first add-on. It's here so you can test it, so it may not work so well on your forum as it worked on mine. I know it's not perfect, but got easy on me. If that interests you, then test it and post some feedback. Suggestions and critics are all welcomed. I hope to do more works in the future.
Also, thank you all the development community here, for sharing all your experiences and tips on developing for XenForo. That helps a lot. And a special thanks for Syndol, the one who always listens to my newbies questions.

The add-on is still on beta stage. But if you want to support it, and the future add-ons, you can donate any value clicking here.

Wow, that's a neat little add-on! Perfect for forum games and such! I will try it out soon ;)


Will it also be possible to set a date/time when the post will be locked?


Well-known member
Gratz on this, you beat me to it though. I was thinking of something similar but using a countdown as well. So thread closing can be done after so many days or posts.


Well-known member
Very nice, I noticed that after I posted but figured I would leave it to give some support. Throw up a paypal email in your first post and I'll throw you a donation for doing this.

Updated to v2.0. Yes, you have the date/time option now! Please test it and send me your feedbacks. Thank you!

That depends on which browser you are using.

Anyway, what where you doing when you got this error? So I can try to reproduce it.

And I think I found a bug, so if you guys are using it and are having some weird behaviours, please let me know, while I try to catch that. Thank you.

So, here is how to open the JS console there: Click the wrench button > Tools > Javascript console > On the window, click the Console button (my browser is pt-br, sorry if the instructions is not accurate). Then you input the same value, and check that console window. Post the error founded. I will try to replicate it here too.

Ok done, here is the error i got:

<b>Fatal error</b>: Call to undefined method DateTime::setTimestamp() in <b>/home/ubrggnet/public_html/library/DS/AutoLockThreads/ControllerPublic/AutoLockThreads.php</b> on line <b>197</b><br />

Oh? It says that the method is not found. Maybe some expert can tell me if that is related to the PHP version itself?
