XF 2.2 Forum and thread types

Forums contain threads and threads contain posts. It's been the essential framework of forums on the Internet since the public migrated from usenet to the web.

The structure is well known and well understood - though the origins of some of the terminology are lost in the mists of time. Who ever came up with the notion of your site being a forum, but these separate containers for related threads also being forums? 🤷🏼‍♂️

But back on topic, and we all know that visiting a forum (the second type) will usually show a list of threads ordered with the most recently updated near the top, and that clicking on any of those threads will show a page with the oldest post first and newer posts underneath and on subsequent pages.

Bending discussion forums to varying purposes

Over the years, forum administrators have been inventive and used the simple messages-in-named-containers structure of forums to build all sorts of content - let's look at the XenForo community as an example.

First, we have announcements and these "Have you seen" threads. These are quite focused on the initial post (or first few posts in some HYS threads), with these posts containing a lot of information... a bit like an article with subsequent comments.

Then we have the suggestions forums, where we ask people to up-vote the ideas they're interested in.

There are also support forums where people are looking for answers to questions or solutions to problems.

And of course there are also forums for general chat and discussions, which most closely fit the original notion of a discussion thread and where you can't really say the threads fit the same model as the other types.

Up until now, these forums and the threads within have all been displayed the same way.

But not any more

With XenForo 2.2, we are introducing the concept of Forum and thread types. This is a massive change with enormous ramifications for forums. Today, we're only really going to talk about the admin and user experience of the new systems, but in a few days we're going to follow up with a developer-focused HYS where we will talk about what's going on behind the scenes here, because we're really rather excited about the potential it unlocks.

There is a lot to talk about, but let's just dive into some examples...


We're prefer you to read all the details below, but if you just want the juicy bits:

That’s correct.

Essentially you’ll never lose the main discussion content like the title, attachments and message content but if you switch from a type that has specific data (such as votes or marked solutions) to a type that does not have that specific data then that specific could be lost.

On related note... after a while, the two-step process to convert thread types in thread view gets annoying. I do understand that there is a possibility that one might accidentally convert a Q&A thread to discussion type losing all the votes in the process so it has value.


Thanks to the team for the great new features and improvements!

This message will surely make me concerned before changing a node type including 5 million posts even I would do that in the test environment first.

Especially the "This may cause some data loss" part.

Basically, this is a question that needs to be answered BEFORE the admin decides to change the node from one type to another.

"This may cause some data loss" is very vague and not clear to the admin what data loss might occur.

What kind of data loss will there be? Which data will NOT be "carried" over if the node is changed?

What would cause that data loss? Meaning... what set of circumstances within that node that is being changed over will trigger the data loss?

I think if Xenforo is a bit more clear on the consequences (or in some cases... lack of consequences) of changing the node, then the admin can make a better decision whether or not to change that node.

Just my 2 cents.

The main data like the main content, replies, images, dates, reactions will be there.

If you change a poll forum to discussion only form, of course you'll lose all voting results. But the discussions below will still be there.

I think it's easy to understand.

If you're still not sure. Create some test threads to try the conversion out before making any real conversion.

Yes, a data matrix might help to visualize which type contains what data.

this reminds me... it is kind of annoying that (from my understanding) we can not have polls in articles/questions/suggestions threads? it should not have been a separate thread type imo 😛

Haven't tested 2.2 yet, but if this is true (Polls can't be in an Article, Question, Suggestion), then it's a wrong approach. Polls (one question) was always part of a post in all scripts (Forums, WP etc).

If someone wants to separate it as post type, then it must be Survey (multiple questions) and not Poll. A survey fits perfectly for separate post type.
