You provided an answer on the below post, I wanted to ask if this should work on Wordpress posts or pages, Im trying to do something similar for posts but I added your code to functions.php and it didn't change anything so I just wanted to check if this was suitable for posts, in short im trying to change the default page break numbering in the urls to use a custom word found from each pagebreak title from the same post.
post pagination names, not numbers
