Problem:
The customer needs to order their Custom Post Types (CPTs) by slug instead of title. For example, a film titled "The Return" with a slug of "return" should be listed under the 'R' section in their film archive. The View options do not support ordering by slug, and an attempt to use a pre_get_posts() filter to achieve this has failed.
Solution:

We suggested using the wpv_filter_query filter to change the orderby parameter. The provided custom code should be added to the theme's functions.php file. The customer needs to replace 1000 with their post view's ID and your_custom_field_slug_here with the custom field slug (name) of the Film.
