Reply To: have_rows causing infinite loop when getting repeater values from another page

I’ve done what i can do, and I also let it peculate in my head for a while.

The reason that I wasn’t seeing how to make this recursive was that I was over complicating it, trying to get your initial loop into the recursion and do the recursion at the same places that you were loading alternate files and also including a check for the target section, but all that really wasn’t needed. Instead the only place it really needs to recurse is when doing a nested block reference.

I haven’t tested this out 100%, but it looks like it should work.

Yeah, the whiles and ifs are nested a bit deep, but I couldn’t see a way to avoid that.

<?php 
  
  // start the blocks content
  // this is the initial loop
  if (have_rows('blocks')) {
    while (have_rows('blocks')) {
      the_row();
      $layout = get_row_layout();
      if ($layout == 'block_reference') {
        $target_page = get_sub_field('target_page');
        $target_section = get_sub_field('target_block_id');
        flexible_block_reference($target_page, $target_section);
      } else {
        // flexible_repeater_block
        if (have_rows('repeater_items')) {
          while (have_rows('repeater_items')) {
            the_row();
            echo 'Item: ' . get_sub_field('title') . '<br />';
          } // end while
        } // end if
      } // end if/else
    } // end while
  } // end if
  
  function flexible_block_reference($post_id, $section) {
    // recurstive function 
    if (have_rows('blocks', $post_id)) {
      while (have_rows('blocks', $post_id)) {
        the_row();
        if (get_sub_field('block_id') == $section) {
          $layout = get_row_layout();
          if ($layout == 'block_reference') {
            $target_page = get_sub_field('target_page');
            $target_section = get_sub_field('target_block_id');
            // recurse
            flexible_block_reference($target_page, $target_section);
          } else {
            // flexible_repeater_block
            if (have_rows('repeater_items')) {
              while (have_rows('repeater_items')) {
                the_row();
                echo 'Item: ' . get_sub_field('title') . '<br />';
              } // end while
            } // end if
          } // end if/else
        } // end while
      } // end if target section
    } // end if
  } // end function
  
  
?>
