Prevent Listing Owners from modifying slug
Currently when a listing is edited it will automatically rewrite the slug to match the title. Since I'm migrating in listings from a php site I want to preserve the old url (minus .php which I can do with a htacess rule). The problem comes in when a listing owner makes any change to their listing. It's going to rewrite the slug.
Example: url on current site to be migrated is /danbrown.php
I import the listing and the new slug is /listings/danbrown/ which is great but when the owner comes along and makes any change the url will change to /listings/dan-brown/ or worse yet, it could be /listings/d-r-dan-brown-p-h-d/.
When you edit a profile in the backend this doesn't happen. Why is it different from the front?
Any help or ideas much appreciated!
