Hi @inhouse
I’m afraid I don’t understand your current setup, so please forgive me if I’m wrong.
Could you please check the documentation here (under the Sub custom field values section): https://www.advancedcustomfields.com/resources/query-posts-custom-fields/? Based on that documentation, your code should be like this:
// filter
function my_posts_where( $where ) {
$where = str_replace("meta_key = 'people_list_%", "meta_key LIKE 'people_list_%", $where);
return $where;
}
add_filter('posts_where', 'my_posts_where');
// args
$args = array(
'post_type' => 'page',
'meta_query' => array(
array(
'key' => 'people_list_%_person_list_user',
'value' => '"' . $author_id . '"',
'compare' => 'LIKE'
)
)
);
$the_query = new WP_Query( $args );
if( $the_query->have_posts() ):
while ( $the_query->have_posts() ) : $the_query->the_post();
I hope this helps 🙂
