I have a custom taxonomy page that queries the custom post types attributed to that taxonomy, in my case the custom post type is "cars", and an example taxonomy page is "exceptional cars" or "convertibles".

On the taxonomy page "taxonomy-luxury-cars.php", I need to display the posts ordered by a custom field "display_order", but I cannot get the posts to display in the correct order.

Basically all I need is to insert an orderby "display_order" (custom field) before the "while have posts" loop, in to reorder the posts.

I have tried numerous snippets found online, but none work correctly.

Snippet 1
(only lists all posts "cars", but I need it for only the posts of the current taxonomy)

$posts = get_posts(array(
 'post_type' => 'cars',
 'posts_per_page' => -1,
 'meta_key' => 'display_order',
 'orderby' => 'meta_value_num',
 'order' => 'ASC'
));

Snippet 2

 $terms = get_the_terms( get_the_ID(), 'luxury-cars' );
 foreach($terms as $term) 
 $posts = get_posts(array(
 'post_type' => 'cars',
 'tax_query' => array(
 array(
 'meta_key' => 'display_order',
 'orderby' => 'meta_value_num',
 'order' => 'ASC'
 )
 ),
 'numberposts' => -1
 ));
 foreach($posts as $post) 
 echo get_the_title();
 
 

Snippet 3

$queried_object = get_queried_object();
$args = array(
 'post_type' => 'cars',
 'term' => $queried_object->slug,
 'orderby' => 'meta_value_num',
 'order' => 'ASC',
 'meta_key' => 'display_order',
 'meta_query' => array(
 array(
 'key' => 'display_order'
 )
 ),
 'tax_query' => array(
 array(
 'taxonomy' => 'luxury-cars',
 'terms' => array(
 $queried_object->term_id
 )
 )
 )
 );
$query = new WP_Query($args);

while ( have_posts() ) : the_post();
