Hi Long,

I need to autopopulate the relationship depending on the value of a post field. This is because when i upload the data, I can populate the user post field but I cannot populate the user relationship field. But I don't understand where I am going wrong with this code. My relationship is set from the post => User. And my aim is to assign the user to that post (university).
```
 add_action( 'rwmb_frontend_after_process', function( $config, $post_id ) {
    if ( 'academics_university' === $config['id'] ) {      //'academics_university is the ID of a user meta field   

  $related_post_ids = empty( $_POST['university'] ) ? (array) $_post['academics_university'] : []; //'university' is the id of my CPT
 
 foreach ( $related_post_ids as $related_post ) {
  MB_Relationships_API::add( $post_id, $related_post_id, 'university_to_user' ); //this is the ID of the relationship university => user
        }
    }
}, 10, 2 );
```
What have I done wrong?

Also I think this is my last issue, then I promise I will leave you be, and no more questions.

Many thanks,
Yasmine

Should it be something more like:

 add_shortcode( 'show_user_post_related', function() {
        $author_id = get_post_field( 'post_author', get_queried_object_id() );

        $post_id = rwmb_meta( 'university_group', ['object_type' => 'university'], $author_id ); //university_group is my name of custom field group, object_type is my name of cpt
        if ( empty( $post_id ) ) {
            return '';
        }

        $output = get_the_title( $post_id );
        return $output;
    } );

The field within the university I want to fetch is also the post_title

Hi Yasmine,

To output the connected posts to a user, please follow this documentation https://docs.metabox.io/extensions/mb-relationships/#posts

Here is the example code:

add_shortcode( 'show_user_post_related', function() {
    $author_id = get_post_field( 'post_author', get_queried_object_id() );

    if ( empty( $author_id ) ) {
        return 'No author ID';
    }

    $connected = new WP_Query( [
        'post_type' => 'university',
        'relationship' => [
            'id'   => 'university_to_user',
            'to' => $author_id, // You can pass object ID or full object
        ],
        'nopaging'     => true,
    ] );
    
    $output = '';
    while ( $connected->have_posts() ) : $connected->the_post();
        $output .= the_title();
    endwhile;
    wp_reset_postdata();

    return $output;
} );
