Reply To: Order get_terms by ACF field, even if the field is not set

I recently built something similar

This is my usort function for ordering terms

function sort_vid_terms_by_menu_order($a, $b) {
  if ($a->sort_order == $b->sort_order) {
    return 0;
  } elseif ($a->sort_order < $b->sort_order) {
    return -1;
  } else {
    return 1;
  }
} // end function sort_terms_by_menu_order

and this is how I get the terms

$args = array(
  'taxonomy' => $taxonomy,
  'hide_empty' => true,
  'parent' => $parent,
  'hierarchical' => true
);
$terms = get_terms($args);
if (!empty($terms)) {
  foreach ($terms as $index => $term) {
    $term->sort_order = intval(get_field('sidebar_menu_order', $term));
  }
  usort($terms, 'sort_vid_terms_by_menu_order');
}
