打开购物车类别模块>显示第二个子项 - Opencart category module > display second child

我一直在尝试实现在侧边栏类别模块中显示类别的第二个子项，如下所示

例如：Toys > boys > RC cars

目前有这个

<ul>
    <?php foreach ($categories as $category) { ?>
    <?php if ($category['category_id'] == $category_id) { ?>
    <li class="cat-active">
        <a href="<?php echo $category['href']; ?>" class="active"><?php echo $category['name']; ?></a>
    <?php } else { ?>
    <li>
        <a href="<?php echo $category['href']; ?>"><?php echo $category['name']; ?></a>
        <?php } ?>
        <?php if ($category['children']) { ?>
        <b class="cc"></b>
        <ul class="col-subcat">
            <?php foreach ($category['children'] as $child) { ?>
            <li>
                <?php if ($child['category_id'] == $child_id) { ?>
                <a href="<?php echo $child['href']; ?>" class="active"><?php echo $child['name']; ?></a>
                <?php } else { ?>
                <a href="<?php echo $child['href']; ?>"><?php echo $child['name']; ?></a>
                <?php } ?>
            </li>
            <?php } ?>
        </ul>
        <?php } ?>
    </li>
    <?php } ?>
</ul>

只显示

男孩>玩具

我不确定如何显示第二个孩子（">男孩>遥控车的玩具"）泰建议

您必须自定义 2 个文件。

目录/控制器/模块/类别.php - 39 行

找到"foreach （$children as $child） {"，并在它下面放置以下代码。

$children_data_2 = array();
$children_2 = $this->model_catalog_category->getCategories($child['category_id']);
foreach ($children_2 as $child_2) {
	$filter_data = array(
		'filter_category_id'  => $child_2['category_id'],
		'filter_sub_category' => true
	);
	$children_data_2[] = array(
		'category_id' => $child_2['category_id'],
		'name'        => $child_2['name'] . ($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'] . '_' . $child_2['category_id'])
	);
}

改变

$children_data[] = array(
	'category_id' => $child['category_id'],
	'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'])
);

自

$children_data[] = array(
	'category_id' => $child['category_id'],
	'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']),
	'children'	  => $children_data_2 // insert this line
);
