CodeIgniter heirarchical loop с многомерным массивом

Question

У меня есть массив в нижней части этого сообщения. Я использую CodeIgniter и этот массив для отображения heirarchical информации по следующей точке зрения:

<?php foreach($products['top_cats'] as $top_cat): // $top_cat ?> 
    <h2><?php echo $top_cat['cat_name']; ?></h2> 
    <?php if(! empty($products['sub_cats'][$top_cat['cat_id']])): ?> 
     <?php foreach($products['sub_cats'][$top_cat['cat_id']] as $sub_cat): ?> 
      <h3><?php echo $sub_cat['name']; ?></h3> 
      <!-- problem below --> 
      <?php $this->load->view('products_table_v', $products[$sub_cat['id']][$n]); ?> 
      <?php var_dump($n); ?> 
     <?php endforeach; ?> 
    <?php endif; ?> 
<?php endforeach; ?> 

$products[top_cats][14] относится к $products[sub_cats][14] и $products[sub_cats][14] относится к $products[products][14] (я надеюсь, что это имеет смысл). Поэтому мне нужно передать $products[products][14] на вид, когда я нахожусь в foreach для $products[sub_cats][14] (опять же, я надеюсь, что это имеет смысл?) ...

Моя проблема в том, что мне нужно передать правильный суб-суб (-sub) к подзапуску (который содержит хороший рабочий цикл foreach). Я не могу понять, как передать массив подзаголовку (я пошел слепой код).

Пожалуйста, помогите.
