bp_blogs_sync_delete_from_activity_comment( bool $retval, int $parent_activity_id, int $activity_id, bool $deleted )

Deletes the blog comment when the associated activity comment is deleted.


Note: This is hooked on the ‘bp_activity_delete_comment_pre’ filter instead of the ‘bp_activity_delete_comment’ action because we need to fetch the activity comment children before they are deleted.



(bool) (Required) Whether BuddyPress should continue or not.


(int) (Required) The parent activity ID for the activity comment.


(int) (Required) The activity ID for the pending deleted activity comment.


(bool) (Required) Whether the comment was deleted or not.
