我在woocommerce产品上添加了一些自定义字段。我使用下面的代码在Woocommerce流程上显示自定义字段：查看;订单和电子邮件。但是我不能让它们出现在可变产品过程中。它完美地适用于单个产品。谁能帮我修复我的代码？非常感谢:)

我不熟悉用于声明自定义字段的钩子。请注意，挂钩与主要产品和产品型号不同。
要将自定义字段添加到变体中，我使用以下方法：
add_action( 'woocommerce_product_after_variable_attributes', function( $loop, $variation_data, $variation ) {
echo '<div class="product_custom_field">';
woocommerce_wp_text_input(
array(
'label' => 'Vendor ID',
'id' => '_vendor_id[' . $variation->ID . ']',
'value' => get_post_meta( $variation->ID, META_PREFIX . 'vendor-product-id', true ),
)
);
woocommerce_wp_text_input(
array(
'label' => 'Updated on',
'id' => '_updated_on[' . $variation->ID . ']',
'value' => get_post_meta( $variation->ID, META_PREFIX . 'last-update', true ),
)
);
echo '</div>';
}, 10, 3 );
要显示该字段，请使用简单的get_post_meta()
get_post_meta( $variation->ID, META_PREFIX . 'vendor-product-id', true );
