header.tpl的代码

          <?php if ($category['children']) { ?>
          <div class="dropdown-menu">
            <?php for ($i = 0; $i < count($category['children']);) { ?>
            <?php $j = $i + ceil(count($category['children']) / $category['column']); ?>
            <?php for (; $i < $j; $i++) { ?>
            <?php if (isset($category['children'][$i])) { ?>
            <div class="column col-lg-2 col-md-3"> <a href="<?php echo $category['children'][$i]['href']; ?>"><?php echo $category['children'][$i]['name']; ?></a>
              <?php if ($category['children'][$i]['children_level2']) { ?>
              <div>
                <ul>
                  <?php for ($wi = 0; $wi < count($category['children'][$i]['children_level2']); $wi++) { ?>
                  <li><img src="image/<?php echo $category['children'][$i]['children_level2'][$wi]['image']; ?>"/> <a href="<?php echo $category['children'][$i]['children_level2'][$wi]['href']; ?>"  ><?php echo $category['children'][$i]['children_level2'][$wi]['name']; ?> </a> </li>
                  <?php } ?>
                </ul>
              </div>
              <?php } ?>
            </div>
            <?php } ?>
            <?php } ?>
            <?php } ?>
          </div>
          <?php } ?>
        </li>

控制器文件header.php的代码

                $children_data[] = array(
                     'name'  => $child['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data) . ')' : ''),
                    'image'  => $child['image'] ? $this->model_tool_image->resize($child['image'], 20, 20) : false,
                    'href'  => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id'])

                );
