Display related cpts ordered by menu order

Kept trying, and changed my code to:

$art = pods('art', get_the_id());

$params = array('name' => 'a_doc_rel');
$docs_rel = $art->field($params);

	if ( ! empty( $docs_rel ) ) {

		foreach ( $docs_rel as $doc_rel ) {
		...
		}
         }

This works just like the code I was using before. But if I add 'orderby' => 'menu_order ASC' like this:

$art = pods('art', get_the_id());

$params = array('name' => 'a_doc_rel', 'orderby' => 'menu_order ASC');
$docs_rel = $art->field($params);

	if ( ! empty( $docs_rel ) ) {

		foreach ( $docs_rel as $doc_rel ) {
		...
		}
         }

then the related fields are not displayed at all.

Unfortunately ordering relationship fields by passing orderby parameters to field doesn’t work. It’s a known issue that we don’t know the cause of. The workaround is to do 2 loops. In the first, build an array of the info you need to output of reach item, where the key is the field to sort by. Then sort the array by key, using key_sort() and then loop the sorted array.

Thanks for your answer!
Could you provide an example of the workaround you propose?
I’m not very good at programming, but with an example I may be able to adapt it to what I need.
Thank you!

Here is an example, where the related field is being sorted by post_title:

hi there!

I coudn’t find how to adapt the code on the link you provided to what I needed.

But I found the answer here:
https://pods.io/forums/topic/sort-relationship-field-according-to-menu_order/

and here’s my code, in case somebody finds it useful:

$art = pods('art', get_the_id());

$docs_rel = $art->field('doc_rel');

	if ( ! empty( $docs_rel ) ) {

  $docs_rel_menu_order = $art->field('doc_rel.menu_order');

  array_multisort($docs_rel_menu_order, $docs_rel);

		foreach ( $docs_rel as $doc_rel ) {
		...
		}
         }

Thanks!
