Thanks guys. I think I may have found a solution.
What I did:
- On
taxonomy-types.php
, get all Items for that type using WP_QUERY. - Loop through them, use
get_the_terms()
to get taxonomy Model for each Item - Still in the loop: use PHP’s
in_array()
function and a$model_ids
array for unique Model checking - Still in the loop: if the Model is unique, store the Item id in an
$item_ids
array - End that loop
- Use WP_QUERY to get Items with
'post__in'
set to the$item_ids
array
