WooCommerce:随处添加/显示产品或版本自定义字段 [英] WooCommerce: Add/display Product or Variation custom field everywhere
问题描述
当前使用WordPress 5.1.1和WooCommerce 3.5.7。我的WooCommerce商店有大约500种产品,由简单易变的产品组成。
每个产品自然都有一个SKU,但是每个产品还具有唯一的ID代码,称为商品码'。我向特定行业销售特定产品。
我已在我的functions.php文件中添加了用于简单和可变产品的自定义字段的代码,该代码在
我的问题是,我试图在购物车,结帐,发票和电子邮件中的商品标题下显示商品代码。 / p>
我已经在互联网上阅读了各种教程来帮助我,但我并不明智,因为每个教程都以不同的方式进行相似的操作。大多数教程假定用户已通过前端输入数据,但我的数据是预设的。

某些PHP / WooCommerce天才可以通过提供代码或将我指向可以帮助我或命名第三方WordPress插件的教程。
我已经重新研究并完成了您现有的代码例如,它不适用于产品变体……这将:
- 在库存标签下的管理产品上显示自定义字段
- 在每个变体的变体选项卡下的管理产品上显示自定义字段
- 保存产品和产品变体的自定义字段值
- 在单个产品页面上显示自定义字段值(同样针对每个选定的变体)
- 在购物车和结帐页面上显示自定义字段值
- 将自定义字段值保存为订单商品元数据
- 在管理订单上显示自定义字段值
- 在订单上显示自定义字段d电子邮件通知

Currently using WordPress 5.1.1 and WooCommerce 3.5.7. My WooCommerce store has around 500 products, made up of simple and variable products.
Each product naturally has a SKU, but each product also has a unique ID code called 'Commodity Code'. I sell specific products to a specific industry.
I have added the code for the Custom Fields for Simple and Variable product in my functions.php file, and this works great at the moment.
My problem is, I have trying to get the 'Commodity Code' to appear under the product title in the Cart, Check Out, invoice and email.
I have read various tutorials on the internet to help me, but I am none the wiser as each tutorial does similar things in different ways. Most of the tutorials assume a user has entered the data via the front-end but my data is preset.
Tutorials I have used to help me are:

Can some kind PHP/WooCommerce genius help me here please by either providing the code or point me to a tutorial that would help me or name a third party WordPress Plugin that will do this.
I have revisited and completed your existing code as for example it was not working on product variations… This will:
- Display a custom field on admin product under inventory tab
- Display a custom field on admin product under variations tab for each variation
- Save the custom field value for products and product variations
- Display the custom field value on single product pages (also for each selected variation)
- Display the custom field value on cart and checkout pages
- Save the custom field value as order item meta data
- Display the custom field value on admin orders
- Display the custom field on orders and email notifications
The code:
// Admin: Add custom field
add_action('woocommerce_product_options_sku', 'vp_add_commodity_code' );
function vp_add_commodity_code(){
woocommerce_wp_text_input( array(
'id' => '_commodity_code',
'label' => __('Commodity Code', 'woocommerce' ),
'placeholder' => __('Enter Commodity Code here', 'woocommerce' ),
'desc_tip' => true,
'description' => __('This field is for the Commodity Code of the product.', 'woocommerce' ),
) );
}
// Admin: Save custom field value for simple product inventory options
add_action('woocommerce_admin_process_product_object', 'vp_product_save_commodity_code', 10, 1 );
function vp_product_save_commodity_code( $product ){
if( isset($_POST['_commodity_code']) )
$product->update_meta_data( '_commodity_code', sanitize_text_field($_POST['_commodity_code']) );
}
// Admin: Add custom field in product variations options pricing
add_action( 'woocommerce_variation_options_pricing', 'vp_add_variation_commodity_code', 10, 3 );

'id' => '_commodity_code['.$loop.']',
'label' => __('Commodity Code', 'woocommerce' ),
