I will add the WP_query to get related posts. I have a CPT DOEN. Each post has one or more related posts using the post-field. The default code rmwb_meta works but I want the Advanced Query Builder in Oxygen to get the related ID's.
What is the correct WP_query?
```
global $post;

$field_id = "hoogtepunten";
$post_id = rwmb_meta( $field_id );

if ( $post_id) {
    echo '<h2 class="related-content-title">Bezienswaardigheden langs de route</h2>';

echo '<div class="related-content">';

foreach( $post_id as $post) {
    setup_postdata( $post ); ?>
```

Hi Cees,

Please notice that the helper function rwmb_meta() retrieves the field value (or called post meta), it is a parameter of WP_Query to get the posts.

You can read more on Oxygen documentation https://oxygenbuilder.com/documentation/other/advanced-query-builder/
and WordPress WP_Query https://developer.wordpress.org/reference/classes/wp_query/#custom-field-post-meta-parameters

If you don't want to use the helper function rwmb_meta(), you can use the WordPress function get_post_meta().
