I have a custom post type
Wine, which has an ACF Field that links to another custom post type
Producer as a
post_object relation. In my Producer, I have a custom taxonomy named
Now, what I'm trying to do is to query all the white wines where the producer's region is x.
Here's what I've tried:
$args = array( 'post_type' => 'wines', 'posts_per_page' => 12, 'tax_query' => array( array( 'taxonomy' => 'type', 'field' => 'slug', 'terms' => 'white' ), array( 'taxonomy' => 'region', 'field' => 'slug', 'terms' => 'alsace' ) ) );
The problem I'm having is the
tax_query is executed on the
wine and not it's
producer. I've looked at the documentation of WP_Query and can't seem to find an example on how to achieve it.
Could anyone please guide me? Thanks.
I've retrieved the list of IDs of the producers to add it to the
$producers = new WP_Query( array( 'post_type' => 'producers', 'posts_per_page' => -1 ) ); $producersIds = wp_list_pluck($producers, 'ID');
After that, I've updated the
$args by adding the meta query:
'meta_query' => array( array( 'key' => 'producer', 'value' => $producerIds, 'compare' => 'IN' ) )
