Meta Box

But the above is from the post field on the custom fields form. I also created a relationship between the user and university. And was actually not sure if this part was needed or not and how to tie it in:

<?php
add_action( 'mb_relationships_init', 'your_prefix_function_name' );

function your_prefix_function_name() {
    MB_Relationships_API::register( [
        'id'         => 'relationship_user_university',
        'reciprocal' => true,
        'from'       => [
            'object_type' => 'user',
            'post_type'   => 'post',
            'taxonomy'    => 'category',
            'meta_box'    => [
                'title' => 'user_to_university_relationship',
            ],
            'field'       => [
                'name' => 'User to University Relationship',
            ],
        ],
        'to'         => [
            'object_type' => 'post',
            'post_type'   => 'university',
            'meta_box'    => [
                'title' => 'university_to_user_relationship',
            ],
            'field'       => [
                'name' => 'University to User Relationship',
            ],
        ],
    ] );
}

Hello - I just wanted to elaborate a little further. As it is still not working, and I thought it would be easier to give a fuller picture:

'<div>get_the_title( $university );
$academics_university = rwmb_meta( 'academics_university' ); //maybe do I have to write its a custom field here?
$academics_university = get_the_title( $university )</div>'

To explain the above: $university is my custom post type. $academics_university is a custom relational post field saved to the user. I created one relationship between user and university too. It works on the backend.

But I am trying to get the $university to show next to the author of a different cpt ($research). The author creates these posts and these posts are also connected to the user and to the university cpt. I believe I need to use the author meta option (on elementor pro template) with the meta key 'academics_university' - as the related post is saved to the user.

Right now, the post ID shows. But I cannot get the university to show and link to the selected $university.

I would really appreciate your advice how to do this! I am not a developer in any way (you can probably tell)

Thanks - and do I add into the php code - or do I need to include into the shortcode on my template. Sorry - not sure where to add it!
