我正在尝试向我的 WooCommerce 产品添加自定义库存设置字段。产品页面将显示一个数字，其中包含两个“仓库”的库存总和。
我有一个工作代码，可以将这样一个字段添加到简单的产品中，一切都很完美。
不幸的是，我对具有产品变体的产品有疑问。我有代码在产品设置中向产品变体添加了一个包含附加库存的字段，但产品页面仅显示标准库存中的库存。
简单产品的工作代码：

woocommerce_wp_text_input(
array(
'id' => '_stock2',
'value' => get_post_meta( $product_object->get_id(), '_stock2', true ),

尝试以下适用于所有产品的替换代码：

应该可以。
