Modify permalink with custom field in the post_type_permalink variable
I migrated from the location-based wordpress multisite structure to a free or paid multisite structure and need bring location back into my permalink structure.
There is a perfect custom field I added with a drop down list called cp_area and I need to add the value of this for each ad_listing post_type to the URL so the listings will be displayed in their proper localiity.
I found that replacing the word "Ads" in the Permilink Settings field called post_type_permalink with "%cp_area%" did not get dynamically replaced with the meta_value for the ad_listing.
After looking through the code I did not find an example from which to copy from or a means by which to accomplish this change. What I would prefer to do would be to make a change in the classipress-child theme if possible.
Any help would be much appreciated !!!
