OpenCart 3.0.2.0レベル3のサブカテゴリ

Question

カテゴリメニューにlvl 3サブメニューを作成しようとしていますが、これまでのところ成功していません。

Iは、foreachループのLVL2内部共通

カタログ/コントローラ/にファイルをmenu.phpする/

// Level 3 
$grandchildren_data = array(); 
    $grandchildren = $this->model_catalog_category->getCategories($child['category_id']); 
     foreach ($grandchildren as $grandchild) { 
      $grandchild_filter_data = array(
       'filter_category_id' => $grandchild['category_id'], 
        'filter_sub_category' => true 
      ); 
       $grandchildren_data[] = array(
        'name' => $grandchild['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($grandchild_filter_data) . ')' : ''), 
        'href' => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $grandchild['category_id']) 
       ); 
     } 

そしてmenu.twigファイル にファイルmenu.php以下のコードを追加私が追加以下のコードは、後の子供のためのforループ内に>

{% if child.children %} 
    <ul> 
     {% for children in child.children %} 
     <li><a href="{{ children.href }}">{{ children.name }}</a></li> 
     {% endfor %} 
    </ul> 
    {% endif %} 

何か提案がありますか？

このお試しください： カタログ\ビュー\テーマ\デフォルト\テンプレート\共通\メニュー：共通\ menu.php

<?php

     $this->load->model('catalog/product'); 

     $data['categories'] = array(); 

     $categories = $this->model_catalog_category->getCategories(0); 

     foreach ($categories as $category) { 
      if ($category['top']) { 
       // Level 2 
       $children_data = array(); 

       $children = $this->model_catalog_category->getCategories($category['category_id']); 

       foreach ($children as $child) {

        $grandchildren_data = array(); 

        $grandchildren = $this->model_catalog_category->getCategories($child['category_id']);
