I have attempted to retrieve the activity object using bp_activity_get_specific() and variations thereof, with no luck. My findings are that I can infact use that function to retrieve an activity, but this activity cannot be a comment or else an empty array is returned.

What’s going on with that? That seems kind of pointless. But that aside, how can I get the parent activity ID, or more to the point, the thread link given the comment ID?

bp_activity_get_specific() should be used like this:

// get activity
$activity_get = bp_activity_get_specific( array( 'activity_ids' => YOURACTIVITYID ) );

// single out the activity
$activity = $activity_get[0];

// grab specific activity item
$activity_body = $activity->content;

@henrywright I have already tried that, but it returns an empty array. As I mentioned earlier, if I supply the ID of a non-comment activity, I get results. No results with activity comments.

Still need help with this :/

I am going to open a trac ticket. I believe this is a bug.

You should state the versions of BP & WP being used.

You can always query the db directly.
In this case, probably:

global $bp, $wpdb;
$wpdb->get_var( "SELECT secondary_item_id FROM {$bp->activity->table_name} WHERE id = $comment_id ");

or maybe

global $bp, $wpdb;
$wpdb->get_var( "SELECT item_id FROM {$bp->activity->table_name} WHERE id = $comment_id ");

Arg, I always forget.

BP 2.0, WP 3.9

I am actually doing exactly that @shanebp! I also added that on the trac ticket I created

[@godavid33 Participant 10 years, 8 months ago]

I was incorrect, it’s not a bug. The solution (thanks to @r-a-y) is this:

$act_item = bp_activity_get_specific( array(
    'display_comments' => true,
    'activity_ids' => ACTIVITY_COMMENT_ID
) );

Nice – and obvious 🙂

Querying the db directly should be avoided if possible – [laziness and bad habit].

[@godavid33 Participant 10 years, 7 months ago]

Yeah, I generally try to avoid it which is why I was trying so hard to find the correct solution 😀
