I am still a noob when it comes to WP and PHP in general.
I would like to hack WP so that when a user submits a new Post for review, instead of showing the usual page, where the post is still there and they can click on the "see post here" link, they are instead redirected to a "Thank you" page.
I really don't want to hack the core files as I know that when WP updates all will be lost; but I can't understand how to amend it via functions.php
I have found a filter in this link http://wordpress.org/support/topic/redirect-to-new-post-after-publish that redirects the user to the actual post on submission; however, I cannot figure out how to amend it for my purposes (to the thank you page).
Please can anyone assist?
