问题描述

我找到了这段代码，并为Journal3主题修改了它，它起作用了。但现在它显示了所有父类别和子类别。我只想看到产品所在的最新儿童类别。有人能帮我调整一下代码吗？在本例中，我只需要最后一类(筹码)

版本：3.0.3.7 日记账：3.1.8

<file path="catalog/controller/product/product.php">
<operation error="log">

<add position="after" index="1"><![CDATA[
$data['text_linked_categories'] = $this->language->get('text_linked_categories');
$query_linked_categories = $this->model_catalog_product->getCategories($product_id);
$linked_categories = array();
foreach( $query_linked_categories as $linked_category_data ) {
$linked_category = $this->model_catalog_category->getCategory($linked_category_data['category_id']);
$linked_category_info['id'] = $linked_category_data['category_id'];
$linked_category_info['href'] = $this->url->link('product/category', 'path=' . $linked_category_data['category_id']);
$linked_category_info['name'] = $linked_category['name'];
$linked_categories[] = $linked_category_info;
}
]]></add>
</operation>

<operation error="log">
<search><![CDATA[$data['manufacturer'] = $product_info['manufacturer'];]]></search>
<add position="before"><![CDATA[
$data['linked_categories'] = $linked_categories;
]]></add>
</operation>
</file>

<file path="catalog/language/nl-nl/product/product.php">
<operation error="log">
<search><![CDATA[$_['text_manufacturer']]]></search>
<add position="before"><![CDATA[
$_['text_linked_categories']        = 'Categorie:';
]]></add>
</operation>
</file>

<file path="catalog/view/theme/journal3/template/product/product.twig">
<operation error="log">
<search><![CDATA[<li class="product-sku"><b>{{ j3.settings.get(stylePrefix ~ 'ProductSKUText') }}:</b> <span> {{ product_sku }}</span></li>]]></search>
<add position="before"><![CDATA[
{% if linked_categories %}
  <li class="product-sku"><b>{{ text_linked_categories }}</b> 
  {% for linked_category in linked_categories %}
            <span><a href="{{ linked_category.href }}">{{ linked_category.name }}</a></span>;
            {% endfor %}
            </li>
            {% endif %}

]]></add>
</operation>
</file>
</modification>

我最终得到了以下工作代码：

                $linked_categories = $this->model_catalog_product->getCategories($product_id);
                $last_category = array_pop( $linked_categories );

                if( $target_category = $this->model_catalog_category->getCategory( $last_category['category_id'] ) ) {

替换您的xml文件中的以下代码：

$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']);
