bbPress.org

Multiple forums per BuddyPress Group is started in bbPress, but likely won’t be finished for several months. There are a few technical challenges regarding performance that don’t make it entirely feasible. If it’s something you need, you’ll want to build it, and if you’re able, contribute back to the bbPress project.

On the whole, I agree that it would be nice to have in core.

I’ve considered this, but without term meta there’s no way to do sticky topics in groups.

Sorry, but that is really VERY important for my new project, so:

Any insight on this?

Also, sorry to derail a bit, but any comment on scalability of this?

I currently run three forums, one each for a different capital city in my country, each with around 15 subforums.

My plan is to combine these into a single site, so each group forum would have 15 subforums – which would be about 45 forums just to replicate what I have now.

I’d then like to create another 10 or so site forums, so that our members from different cities can discuss general topics. And then I’d like to add more groups – initially I’d be adding 3 more groups, for 3 more cities in my country, which would be another 45 forums.

That right away takes me up to 106 forums (10 sitewide, 6 group forums and 90 subforums), before I even start expanding the geographic reach of our groups beyond our country’s borders.

Let’s say I expand into 50 different cities, I’m looking at about 810 subforums (10 sitewide, 50 group forums, 750 subforums).

John mentions “There are a few technical challenges regarding performance that don’t make it entirely feasible” and I wonder if this was what he was getting at?

Perhaps I’m posting this in the wrong section.. but figured you’re probably going to run into a similar issue, moebis

moebis – just took a look at this, I may have a more recent version than you use in your fix above.

Here is how to play with my hack in the latest trunk:

EDIT: /bbpress/includes/extend/buddypress/group.php

Delete lines 609-614 and add “?>” back to line 609.

The code I have at these lines is this:

<?php bbp_get_template_part( ‘form’, ‘topic’ ); ?>

<?php else : ?>

<?php bbp_get_template_part( ‘feedback’, ‘no-topics’ ); ?>

Probably not what I want to comment out. What I did find though is this (lines 567-581):

// Suppress subforums for now
add_filter( ‘bbp_get_forum_subforum_count’, ‘__return_false’ );

// Set up forum data
bbpress()->current_forum_id = $forum->ID;
bbp_set_query_name( ‘bbp_single_forum’ ); ?>

<?php

// Remove the subforum suppression filter
remove_filter( 'bbp_get_forum_subforum_count', '__return_false' );

I highlighted a few things:
1) Topics are only being displayed from group subforum 2 (believe you mentioned this above). This should be easy enough to fix
2) I thought I was posting in the Group Forum when I used the default form below, but clearly (as per highlight 3) this is now set to group subforum 2
3) Default Create New Topic is set to Group Subforum 2. I assume this was the “last retrieved forum” and is probably easy enough to fix. In my case, I’ll probably be changing my group forums to a category anyway, so I don’t actually want people starting new topics from this page.

@stickfinger: moebis provided his hack above. If you weren’t able to follow his instructions, then it’s probably not a good idea that you try to do this modification, and wait for the official release when the bbPress team get it sorted.

As both moebis and I have pointed out, there are a few ‘issues’ at trying to force it to do this and that’s probably why the bbPress team have held off on the official release.

Just came back to this after a number of months and see there are a few new versions out

Have group subforums been implemented yet? I couldn’t tell from the release notes.

Hello,

I really needed this feature so I dug into the code and came up with a solution that doesn’t modify core files. The solution hooks the query pre_get_posts and uses the buddypress ‘plugins’ template file to catch and display the group sub forums.

This probably isn’t the most efficient solution but it seems to work in my environment. I’ll post back if I notice any issues as more subforums are created.

Here are the functions – place in your theme’s functions.php. I also included my plugins.php file also.

I’m implementing derricksmith01’s solution but I couldn’t find this file in the latest version of buddypress (Version 2.2.3.1):
/buddypress/groups/single/plugins.php
but found it here:
plugins/buddypress/bp-templates/bp-legacy/buddypress/groups/single/plugins.php

His solution worked (awesome!!!!) but only when I modified both my functions.php file in my child theme and the plugins.php file in the core files. The plugins.php mod will get erased with the next buddypress update. I tried recreating the same file structure to house the plugins.php file in my child theme:
childtheme/buddypress/bp-templates/bp-legacy/buddypress/groups/single/plugins.php
but that did not work either.

Any one know if derricksmith01’s fix is possible without changing a core file?

A follow up observation on this:
I see in my breadcrumb that a sub-forum of a group’s forum reads correctly:
Forums>Group Forum>Group sub-Forum

But when I make a sub-sub-forum the breadcrumb breaks down:
Forums>Group sub-sub-Forum
instead of:
Forums>Group Forum>Group sub-Forum>Group sub-sub-Forum

However in both the Group sub forum and the Group sub-sub forum the forum displays, and is protected by, the parent Group.
