在产品页面上显示最新的子类别 - Opencart

Question

我找到了这段代码，并为 Journal3 主题修改了它，它可以工作。 但现在它显示了所有父子类别。我只想查看产品所在的最新子类别。 有人可以帮我调整代码吗？在这种情况下，我只需要最后一个类别（筹码）

版本：3.0.3.7 日记：3.1.8

            </li>
            {% endif %}

]]></add>

我最终得到了这个工作代码：

在您的 XML 文件中替换以下代码：

<modification>

<name>Show Linked Categories on Product page</name>

$query_linked_categories = $this->model_catalog_product->getCategories($product_id);
//echo '<pre>'; print_r($query_linked_categories); echo '</pre>';
$linked_categories = array();
foreach( $query_linked_categories as $linked_category_data ) {
$linked_category = $this->model_catalog_category->getCategory($linked_category_data['category_id']);
//echo '<pre>'; print_r($linked_category); echo '</pre>';
$linked_category_info['id'] = $linked_category_data['category_id'];
$linked_category_info['href'] = $this->url->link('product/category', 'path=' . $linked_category_data['category_id']);
