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
?>
