$post in 3.7

[Opserty]

Use the information I gave you in my previous post, you could just add it to $post yourself...

If you want to see what vBulletin is doing with your code, start with the form submission. (Look at where the form posts too, you can find it by looking at the HTML code for the form.) Follow it through the relevant PHP files and see what vBulletin is doing to it.

Most likely the following files will be appropriate:

newreply.php
newthread.php
functions_newpost.php
