Timeline refers to gallery name, not item
Using Jamroom
I didn't reply yesterday because I figured you'd get it, this sentence was important "....... Important things about forum posts is they will all have a 'forum_group_id' on every post which will be the ID of the initial post in the thread which will contain the title of the discussion........"
That's the key to getting the forum title and category. Pass that in to the {jrCore_db_get_item..... and you should get back an array with the info wanted. You can do the same thing to get any info you want.
Whats your code now? and whats the goal you're not able to reach?
so im guessing its something in the updates that fixed the issue.
