仅显示Opencart中类别模块的子类别

Question

是否有方法或扩展名修改类别模块，使其仅显示当前顶级类别页面的子类别。

例如，如果我的“笔记本电脑&桌面”类别页面，侧边栏模块只会列出与“笔记本电脑&桌面”的范畴，如“苹果电脑”和“电脑”与相关联的子类别主标题“笔记本电脑&桌面”（而不是列出或显示任何其他顶级类别）。

以下列方式更新部分的catalog/controller/module/category.php，以仅显示左列中的子类别。

$cur_category_id = $this->data['category_id']; // new code 
    foreach ($categories as $category) { 
     $children_data = array(); 

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

     foreach ($children as $child) { 
      $data = array(
       'filter_category_id' => $child['category_id'], 
       'filter_sub_category' => true 
      ); 

      $children_data[] = array(
       'category_id' => $child['category_id'], 
       'name'  => $child['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($data) . ')' : ''), 
       'href'  => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id']) 
      ); 

      if($cur_category_id && $cur_category_id == $category['category_id']){ 
       $this->data['heading_title'] = $category['name']; 
       $this->data['categories'][] = array(
        'category_id' => $child['category_id'], 
        'children' => array(), 
        'name'  => $child['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($data) . ')' : ''), 
        'href'  => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id']) 
       ); 
      } 
     } 

     $data = array(
      'filter_category_id' => $category['category_id'], 
      'filter_sub_category' => true 
     ); 
     /* 
     $this->data['categories'][] = array(
      'category_id' => $category['category_id'], 
      'name'  => $category['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($data) . ')' : ''), 
      'children' => $children_data, 
      'href'  => $this->url->link('product/category', 'path=' . $category['category_id']) 
     ); */ 
    } 

注：正如我前面加，只有子类别将显示你的问题的评论，并不会有任何选项来选择添加到父类别的产品。

祝你有美好的一天:)！
