Querying posts globally based on custom taxonomy with its own taxonomymeta table

For those running into issues in the future, this is what I did: I made my pre_get_posts function that queries the taxonomy as normal for testing if an taxonomy ID is not in a list: $q->set( ‘tax_query’, array(array( ‘taxonomy’ => ‘tax’, ‘field’ => ‘id’, ‘terms’ => tax_get_inactive(), ‘operator’ => ‘NOT IN’ ))); Then, I implemented …
