How to enter a list of links from a custom field in Wordprress?

Question

WordPress

I want to display similar posts, selecting them manually for each post. I found a suitable script that receives 'my_related_posts'post IDs from an arbitrary field (they are indicated there separated by commas) and makes links to them.

if ($my_related_post_ids = get_post_meta($post->ID, 'my_related_posts', true)):
        $related_args = array(
            'posts_per_page' => -1, // сколько постов будет указано в админке, столько и выведется
            'post__in' => explode(',', $my_related_post_ids), // в качестве значения нужно будет передать массив
            'orderby' => 'post__in', // посты будут сортироваться в том же порядке, в котором они перечислены в админке
        );
        $my_query = new WP_Query($related_args);
        // если посты, удовлетворяющие нашим условиям, найдены
        if ($my_query->have_posts()):
            // выводим заголовок блока похожих постов
            echo '<h4 class="related">' . get_post_meta($post->ID, 'my_related_posts_title', true) . '</h4><ul class="relatedlist">';
            // запускаем цикл
            while ($my_query->have_posts()): $my_query->the_post();
                echo '<li class="relatedlist-item"><a class="relatedlist-link" href="' . get_permalink($my_query->post->ID) . '"><div class="relatedlist-thumbnail">' . get_the_post_thumbnail(null, 'medium', array('alt' => get_the_title())) . '</div>' .
                $my_query->post->post_title . '</a></li>';
            endwhile;
            echo '</ul>';
        endif;
        wp_reset_postdata();
    endif;

But it takes its title ( ) as the text of a link to a similar post $my_query->post->post_title, and I want to prescribe my own. I could also write them, separated by commas, into another arbitrary field. How to change the code so that the link texts are also taken from another field and substituted in a loop?

To solve the problem, use the Advanced Custom Fields Pro plugin, it will allow you to add any number of post ID pairs + New title with a convenient interface to each post:
For example, the name of the relatives repeater field, the relative_id and relative_title subfields, then the code will look like this:

<?php if( have_rows('relatives') ): ?>
  <ul>
  <?php while ( have_rows('relatives') ) : the_row(); ?>
  <li><a href="<?php $id = get_sub_field('relative_id'); echo get_the_permalink($id); ?>"><?php the_sub_field('relative_title'); ?></a></li>
 <?php endwhile; ?>
  </ul>
<?php endif; ?>

Almost the same thing can be done with regular ACF without PRO
