Opencart 中的第三级类别

Question

我的类别结构是：

Electronics
    -TV
       --LG
       --ONIDA
    -Fridge
       --Whirlpool
       --Videocon
    -Music Player
       --Sony
       --LG
Furniture
    -Wooden
       --Chair
       --Bed
    -Metal
       --Chair

我的主要类别是Electronics, Furniture； 子类别是TV, Fridge etc，子子类别是LG, Onida etc。那就是我有3 level categories. 我必须在main navigation menu in Opencart 中显示这些。

但在Opencart main category and sub categories 中只显示。 Third level category 不显示。

所以我如何显示第三级类别。我在这里附上一张图片，更清楚地说明我的要求。

我的 Opencart 版本是 2.0.3.1

这是显示类别菜单的代码。

catalog\view\theme\default\template\common\header.tpl

 <ul class="nav navbar-nav">
    <?php foreach ($categories as $category) { ?>
    <?php if ($category['children']) { ?>
    <li class="dropdown"><a href="<?php echo $category['href']; ?>" class="dropdown-toggle" data-toggle="dropdown"><?php echo $category['name']; ?></a>
      <div class="dropdown-menu">
        <div class="dropdown-inner">
          <?php foreach (array_chunk($category['children'], ceil(count($category['children']) / $category['column'])) as $children) { ?>
          <ul class="list-unstyled">
            <?php foreach ($children as $child) { ?>
            <li><a href="<?php echo $child['href']; ?>"><?php echo $child['name']; ?></a></li>
            <?php } ?>
          </ul>
          <?php } ?>
        </div>
        <a href="<?php echo $category['href']; ?>" class="see-all"><?php echo $text_all; ?> <?php echo $category['name']; ?></a> </div>
    </li>
    <?php } else { ?>
    <li><a href="<?php echo $category['href']; ?>"><?php echo $category['name']; ?></a></li>
    <?php } ?>
    <?php } ?>
  </ul>

注意：不建议直接在内核中进行更改 文件。您可以对 vqmod 进行相同的更改。此处给出的更改 在默认模板中进行了测试，在其他模板中可能会有所不同 自定义主题。

(1) 打开文件catalog/controller/common/header.php并搜索

$children_data = array();

然后写下面的代码之后

$children_lv3_data = array();

2) 在同一文件替换

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

下面的代码

$children_lv3 = $this->model_catalog_category->getCategories($child['category_id']);

if($children_lv3)
{    

    foreach ($children_lv3 as $child_lv3) 
    {
        $filter_data_lv3 = array(
        'filter_category_id'  => $child_lv3['category_id'],
        'filter_sub_category' => true
        );

        $children_lv3_data[] = array(
        'category_id' => $child_lv3['category_id'],
        'name'  => $child_lv3['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data_lv3) . ')' : ''),
        'href'  => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id'] . '_' . $child_lv3['category_id'])
        );
    }

    $children_data[] = array(
            'children_lv3' => $children_lv3_data,
    'name'  => $child['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data) . ')' : ''),
    'href'  => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id'])
    );

}

else
{

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

3) 打开文件catalog/view/theme/default/template/common/header.tpl并搜索

<li><a href="<?php echo $child['href']; ?>"><?php echo $child['name']; ?></a></li>

在后面加上下面的代码

<?php if(isset($child['children_lv3']) && count($child['children_lv3'])>0){ ?>
                            <ul> 
                               <?php foreach ($child['children_lv3'] as $child_lv3) { ?>
                               <li><a href="<?php echo $child_lv3['href']; ?>"><?php echo $child_lv3['name']; ?></a></li>
                                <?php  } ?>
                            </ul>
                        <?php } ?>
