我正在使用PDF打包插件（WooCommerce PDF Invoices）在下订单后创建装箱单。和捆绑产品的Product Bundles插件。
在这些PDF中，我想区分捆绑产品的容器与其子容器。
目前我正在使用Product Bundles：
if(wc_pb_is_bundle_container_cart_item($item) )
它检查项目是否是捆绑产品的容器然后返回true。我需要一个类似的函数，如果item是child或者在bundle中，它将返回true。
这是包装单pdf正文的代码：
<?php
/**
* PDF packing slip template body.
*
* This template can be overridden by copying it to youruploadsfolder/woocommerce-pdf-invoices/templates/packing-slip/simple/yourtemplatename/body.php.
*
* HOWEVER, on occasion WooCommerce PDF Invoices will need to update template files and you
* (the theme developer) will need to copy the new files to your theme to
* maintain compatibility. We try to do this as little as possible, but it does
* happen. When this occurs the version of the template file will be bumped and
* the readme will list any important changes.

仅当产品是任何产品包的一部分时，我才想追加产品名称前面的----。只是想要这个检查，我无法弄清楚我该怎么做
感谢。
答案 0 :(得分：1)
问题是您使用 Cart Functions 而不是 Order Functions 。
首先，您需要使用wc_pb_is_bundle_container_order_item代替wc_pb_is_bundle_container_cart_item，因为我们正在检查订单商品。
除此之外，wc_pb_is_bundled_order_item是您应该用来确定产品是否是容器项的子项的检查。这很重要，因为它会检查项目是否有父容器，这样当您也按顺序排列非捆绑项目时，您的代码可以扩展。
以下是问题的部分相关代码。
<?php } else { ?>
<tr class="item">
<td width="10%" style="float:right;">
<?php echo $item['qty']; ?>
</td>
<td width="5%" style="float:right;">
<?php
// Adding a check to see if current item is a child of a container
$item_name_padding = wc_pb_is_bundled_order_item( $item ) ? '----': '';
echo $item_name_padding . $item['name'];
//echo 'i m child';
do_action( 'woocommerce_order_item_meta_start', $item_id, $item, $order );
$templater->wc_display_item_meta( $item, true );
$templater->wc_display_item_downloads( $item, true );
do_action( 'woocommerce_order_item_meta_end', $item_id, $item, $order );
?>
</td>
<td width="25%" style="float:right;">
<?php echo $product && $product->get_sku() ? $product->get_sku() : '-'; ?>
</td>
</tr>
<?php }} ?>
