Found a solution on the forum, however...


add_action( 'mb_relationships_init', function () {
    MB_Relationships_API::register( array(
        'id'   => 'stud_to_teach',
        'from' => array(
            'object_type' => 'user',
            'query_args' => array( 'role__in' => 'student' ),
            'meta_box'    => array(
                'title'       => 'Manages',
                'field_title' => 'Select Users',
            ),
        ),
        'to' => array(
            'object_type' => 'user',
            'query_args' => array( 'role__in' => 'teacher' ),
            'meta_box'    => array(
                'title'       => 'Manages users',
                'field_title' => 'Select Users',
            ),
        ),
    ) );
} );

This shows the field on both user role's profile. Can I make it show vice versa?
Eg. Teacher's profile can choose student, student can choose teacher

Hi Omni,

You can use the extension MB Include Exclude to show the relationship field on the specific role. For example:

add_action( 'mb_relationships_init', function () {
    MB_Relationships_API::register( array(
        'id'   => 'stud_to_teach',
        'from' => array(
            'object_type' => 'user',
            'meta_box'    => array(
                'title'       => 'Select Teacher',
                'include' => array(
                    'user_role' => 'student'
                )
            ),
            'field' => array(
                'query_args' => array( 'role__in' => 'student' ),
            )
        ),
        'to' => array(
            'object_type' => 'user',
            'meta_box'    => array(
                'title'       => 'Select Student',
                'include' => array(
                    'user_role' => 'teacher'
                )
            ),
            'field' => array(
                'query_args' => array( 'role__in' => 'teacher' ),
            )
        ),
    ) );
} );

In the user profile of the student role, there is only a relationship field to select teacher and vice versa.
