I have a public root group with three private subgroups. The main group is coupled with a blog. What I want is to show the new published posts titles of this blog in the subgroups activity streams. How to do this?

It was imposible to enable the group blog for these three subgroups by selecting the existing blog coupled with the main group, because in the drop-down menu it was not displayed, so I enabled it through the phpMyAdmin. In this way, now I can see that the subgroups are coupled with the root group’s blog, but the new posts of this blog are not included in the activity stream of them.

You can use my BP Group Hierarchy Propagate plugin for this. Set the propagation direction to downwards on the BP Group Hierarchy settings page. The only caveat is that this will propagate all top-level group activity down to the subgroups.

@haystack, I have tested your plugin and I love it. But, it seems that it needs two additional options (sure, from my point of view): a possibility to restrict its action to one /or several/ group of groups and the possibility to choose what kind of activities to be propagated /eg. new blog posts/ (maybe with the optional parameters of the bp_has_activities() function?).

@haystack, I am tempted to modify a little your plugin, but I am not sure how to do that. I need to propagate down ONLY the new blog posts activities from a particular root group with id 2. I think that in the propagate_content_down() function of your plugin I must add somehow these parameters: ‘action’ => ‘new_blog_post’, ‘primary_id’ => 2. Can you sugest how to do this?

@iurie I have added filters that will allow you to modify the template arguments and intercept the results on the Github version, but there is a fundamental problem with this approach. The way the plugin works is that it replaces the entire activity stream of a viewed group with the propagated activity stream. This means that filtering the stream to include only items of type ‘new_blog_post’ and ‘new_groupblog_post’ would result in nothing but new blog post activity items in each viewed group’s stream.

What I think you’re after is a “cherry-picked” approach, such that you have the full activity stream for the viewed group with the addition of items of types ‘new_blog_post’ and ‘new_groupblog_post’ from the parent group (or group that you specify). This is a whole heap more complex and not something the ‘bp_has_activities()’ function offers by default. I’m not sure quite how you’d go about doing that except by diving into the SQL modification filters such as ‘bp_activity_get_where_conditions’ or building some sort of meta query.

Ultimately, all of this may be overkill for your needs. Perhaps you need to rethink your UI instead – you could have a widget on each subgroup’s activity stream page that shows nothing but the blog posts from the specified group. It wouldn’t be exactly what you’re after, but it would at least show the posts to members of the sub-groups.
