Reply To: Repeater loop in a wp_query loop

The problem is that the loop that starts with

while ($subloop->have_posts()) : $subloop->the_post();

is the second nested post loop. When you call

$subloop->reset_postdata();

This is resetting the post data to the post in “The Loop” and not the post data of your first nested loop. This is a common error.

When you have

The Loop (main WP query loop)
    => Nested loop
        => Nested loop

you must loop through the posts in the second nested loop as well as any more deeply nested loop in a way other than by using the standard WP while (have_posts()) method.

For example, instead of your code

  while ($subloop->have_posts()) : $subloop->the_post();
  if (have_rows('mega_menu')):
    while (have_rows('mega_menu')) : the_row();
      echo the_sub_field('menu_overskrift');
      while (have_rows('mastersidelinks')) : the_row();
        $subnavitemID = get_sub_field('masterside_sub_links', false, false);
        echo get_the_title($subnavitemID);
      endwhile;
    endwhile;
  else :
  endif;
  endwhile;
  $subloop->reset_postdata();

you need to use something like this

  if (count($subloop->posts)) {
    // do not use $posts as a variable
    // because it will overwrite $post in the parent loop
    foreach ($subloop->posts as $nested) {
      $post_id = $nested->ID;
      while(have_rows('mastersidelinks', $post_id)) {
        the_row();
        $subnavitemID = get_sub_field('masterside_sub_links', false, false);
        echo get_the_title($subnavitemID);
      } // end while have rows
    } // end foreach
  } // end if count posts
