My fields are as follows: authors is a group field and within that I have a subfield of people (amongst other subfields). People is a multiple post_object select field.
I have the impression from this thread that it is possible to query subfields in this way…
$images_query = new WP_Query([
'posts_per_page' => -1,
'post_type' => 'images',
'meta_query' => [
[
'key' => 'authors_%_people',
'value' => ['85'],
'compare' => 'IN'
],
],
]);
It is not working, please could you advise me.
