Activity template function to get parent activity's user ID
|Reported by:||DJPaul||Owned by:|
bp_get_activity_parent_content() exists and returns the content of the parent activity item. This is used for the "in reply to" link, when an activity comment reply appears in a person's activity stream. I'd like to add a function which returns the activity parent's user ID, so templates can display information about the user that the comment was in reply to.
