Thinking out loud about this. A post (reply) must be part of a topic, and a topic part of a forum, right? And right now, here, this post is part of the “forum_id” topic, which is in the “Troubleshooting” forum. So, the information is available in the template file, if it’s being displayed here in a topic. Have you looked in your themes topic.php file to see what provides that information right now? If you’re checking this in WordPress, there will be some additional hoops to jump through, like passing the post ID and globalising some variables, but it seems like the information is available.
What have you tried so far?
I figured this out.
I found that if you go to the dashboard and mouse over the edit option for a post, the ID appears on the status bar at the bottom of the window.
Oh, I didn’t realize you just needed the forum ID one time. Glad you figured it out.
