推荐答案

更新了最后一个功能，以避免其他与订单项"相对的订单项出现错误.

Updated last function to avoid errors with other order item types that "line items".

要使其仅在管理员上可见，在最后一个功能中，您需要将订单项元键从'articleid'更改为'_ articleid'(添加键开头的下划线)，如:

To make it only visible on admin, In your last function, you will need to change the order item meta key from 'articleid' to '_articleid' (adding an underscore at the beginning of the key) like:

// Save as custom order item meta data and display on admin single orders
add_action( 'woocommerce_checkout_create_order_line_item', 'add_articleid_as_orders_item_meta', 10, 4 );
function add_articleid_as_orders_item_meta( $item, $cart_item_key, $values, $order ) {
    $articleid = $values['data']->get_meta('articleid'); // Get product "articleid"

    // For product variations when the "articleid" is not defined
    if ( ! $articleid && $values['variation_id'] > 0 ) {
        $product   = wc_get_product( $values['product_id'] ); // Get the parent variable product
        $articleid = $product->get_meta( 'articleid' );  // Get parent product "articleid"
    }

    if ( $articleid ) {
        $item->add_meta_data( '_articleid', $articleid ); // add it as custom order item meta data
    }
}

对于手动订单，您将使用以下内容:

For manual orders you will use the following:

add_action( 'woocommerce_before_save_order_item', 'action_before_save_order_item_callback' );
function action_before_save_order_item_callback( $item ) {
    // Targeting only order item type "line_item"
    if ( $item->get_type() !== 'line_item' )
        return; // exit

    $articleid = $item->get_meta('articleid');

    if ( ! $articleid ) {
        $product = $item->get_product(); // Get the WC_Product Object
        
        // Get custom meta data from the product
        $articleid = $product->get_meta('articleid');
        
        // For product variations when the "articleid" is not defined
        if ( ! $articleid && $item->get_variation_id() > 0 ) {
            $product   = wc_get_product( $item->get_product_id() ); // Get the parent variable product
            $articleid = $product->get_meta( 'articleid' );  // Get parent product "articleid"
        }

        // Save it as custom order item (if defined for the product)        
        if ( $articleid ) {
            $item->update_meta_data( '_articleid', $articleid );
        }
    }
}

代码进入活动子主题(或活动主题)的functions.php文件中.经过测试，可以正常工作.

Code goes in functions.php file of the active child theme (or active theme). Tested and works.
