I understand that using the php option to return a value for a contextual filter is frowned upon, but I have an inherited Drupal 6 site I’m attempting to upgrade to 8, which has several views that use this method.
An example of a php contextual filter can be seen here for Drupal 7:
Can anyone recommend a straight forward alternative to providing a more advanced way of returning a value for a contextual filter to use?
I’ve tried using hook_views_query_alter() and using addWhere() and leftJoin() within that to try to re-write the query to match what the contextual filter would be, but this is an infinitely more time consuming and complex way of approaching it, so am really looking for a way to reference some php somehow for a contextual filter to return.
Any suggestions would be really appreciated!
