Pagination last link redirect?

Hey there CI community, I'm a bit stumped on this one.

Working on a forum script and I want it so when you post on a topic, it will redirect you to view your post. I've done the anchor part such as #post_id to drag you to where your post is, but how do I redirect to the last pagination link on the topic?

Thanks in advance, Tyler.
