Update relations with Advanced Custom Fields

    I installed Orbis theme+plugin which brought me to posts to posts. I used ACF (v5) to create a front-end table that displays lots of information about each project and each line (each project) has a form where it’s possible to update several fields. One of them should be the relation between projects and persons (two custom post-types).
    I belive that what I should do is create an action that updates the connections to that post (project) every time the ACF field value is updated.
    From what I found I can use this to trigger the action when the ACF field is updated . But I have no idea how to do the rest. Any help?

    add_filter(‘acf/update_value/name=person’, …

    for anyone interested, it may not be the best solution but it works. replace YOUR_ACF_FIELD with your actual acf field

    //Function to delete any relation between the updated post and orbis_persons
function wpa85599_acf_update_value( $value, $field, $post_id ){
    $YOUR_ACF_FIELD = $value;
    //Get the updated project ID
    $project_id = get_the_ID();

     //find every orbis_person
     $loop = new WP_Query( array( 'post_type' => 'orbis_person') );
      if ( $loop->have_posts() ) :
        //for each person, het the ID and disconnect the person from the updated project
        while ( $loop->have_posts() ) : $loop->the_post();
             $to = get_the_ID();
             p2p_type( 'orbis_projects_to_persons' )->disconnect( $project_id, $to );

        endwhile;
    endif;
    wp_reset_postdata();

    //make a new connection between your new person and the updated project
    p2p_type( 'orbis_projects_to_persons' )->connect( $project_id, $YOUR_ACF_FIELD, array(
    'date' => current_time('mysql')) );

    //define and return YOUR_ACF_FIELD as your new ACF field value
    $value = $YOUR_ACF_FIELD;
 return $YOUR_ACF_FIELD;
};

add_filter('acf/update_value/name=YOUR_ACF_FIELD', 'wpa85599_acf_update_value', 10, 3);
