I custom craft my excerpts, and I’d like to have the sitewide activity stream show my excerpt and not the bp excerpt. Can this be done?

hmm, well i was going to suggest using the filter…

in bp_blogs_record_post
'content' => apply_filters( 'bp_blogs_activity_new_post_content', $activity_content, &$post, $post_permalink )

which calls bp_blogs_record_activity but it does not pass the untouched content to tweak to your liking.
$content = apply_filters( 'bp_blogs_record_activity_content', bp_create_excerpt( $content ) ;

It’s bp_create_excerpt() that’s killing me.

If I could replace (or change) that to check for the existence of an excerpt and, if found, spit THAT back, it’d be perfection.

Isn’t it possible to grab the excerpt based on &$post?
$post->post_excerpt.

[EDIT]
I see what you guys are talking about now with bp_create_excerpt()!

You can either request an additional parameter for unfiltered text in the “bp_blogs_record_activity_content” filter or in the “bp_create_excerpt” filter.
Definitely a good idea for a patch!

a crazy idea – the BP_Activity class on the save method has another set of filters.

$this->content = apply_filters( 'bp_activity_content_before_save', $this->content, &$this );

Using $this
check for the activity type (new_blog_post),
grab the secondary_item_id which is the post_id (item_id is the blog_id here)
then lookup your custom excerpt in wp with the post_id and replace?

Thank you both of you! Now I have a better start point!

That would work as well!
Though, you’d have to grab the excerpt either through a DB query or some WP functions (I suggest the DB query only if you’re using Multisite).

Some free time returned.

You can either request an additional parameter for unfiltered text in the “bp_blogs_record_activity_content” filter or in the “bp_create_excerpt” filter.

So that now exists thanks to @r-a-y ( http://trac.buddypress.org/ticket/2481 )

I’m assuming I need to tell bp_blogs_record_activity_content to use the excerpt, but would that just be using the code r-a-y already made here: http://pastebin.com/s9PajKjU or something else.

@ipstenu – Take the code I posted and then you’ll also need to apply a filter so BP doesn’t create its own excerpt.

This can be done with:

Untested, give it a shot and report back.

Okay, we’ll see how that goes (I have a scheduled post for 1am every day )

Oy. The fun!

Brilliant!

For posts without a crafted excerpt, it’s the same as always. For posts WITH one, it’s the excerpt! Now to trick it into pulling featured post images ….

Any luck getting it to pull in the first image of the blog post as well?

Some pointers, but not a solution:
@ipstenu

The featured image is referenced by _thumbnail_id . It’s not stored in the $post data structure, instead it’s held in the postmeta table.

There are look up functions to get the featured image from the post_id of course, but not sure how efficient these would be… I guess you still have to have to switch to the correct blog (switch_to_blog()), before using the post_id in the 3.0 multisite world?

Maybe I’m taking it off track here

Yeah, switch to blog is why I’ve not gotten any further, alas I do wish this worked like FaceBook, somewhat, but unless I had it pulled in on bp_blogs_record_activity_content, maybe tell that ‘and get post_thumbnail_id’ but right now I’m happy with the excerpt!

@ipstenu:

We came up with a solution to include the featured image (post_thumbnail) in the activity stream. The solution avoids the need to use switch_to_blog

It isn’t simple, but it might help:

We removed the action bp_blogs_record_post and replaced it with our own version that populates the content field with the post_thumbnail (you could also add the excerpt), i.e. $activity_content = get_the_post_thumbnail( $post_id );

Unfortunately, bp_blogs_record_activity then takes the image and mangles it. To get around this we had to implement our own version of bp_blogs_record_activity, and call that instead from our blogs_record_post function.

You can see the whole set of code here:

Then in your activity loop, just use bp_activity_content_body() to display the thumbnail / excerpt, etc.

IMHO – bp_blogs_record_activity() needs a rework in the core to give theme designers much more control.
