在 WooCommerce 中更新自定义订单项元数据

Update custom order item meta in WooCommerce

我遗漏了一些东西。我看过几篇关于如何更新项目元数据的文章,但我无法让其中任何一篇工作。我需要获取 item_id 但我不知道该怎么做。

$your_phone = $item->get_meta('dinner_phone'); // 1115559999
$update_phone = wdc_format_phone($your_phone); // comes back (111) 555-9999

wc_update_order_item_meta($item_id,'dinner_phone', $update_phone); //I want to update with new format

$new_phone = $item->get_meta('dinner_phone'); // doesn't work I still get 1115559999

我已经尝试通过以下方式拉 Item_id

foreach ( $items as $item ) {
    $product_id = $item->get_product_id();
    $item_id = $item['item_id'];
    break;
}

也试过这个

    foreach ($items as $key => $product ) {
      $item_id = $key;
   }

您将从现有的 WC_Order 对象 $order 变量中使用以下内容:

foreach ( $order->get_items() as $item-id => $item ) {
    $dinner_phone   = $item->get_meta('dinner_phone'); // 1115559999
    if ( ! empty( $dinner_phone ) ) {
        $formatted_diner_phone = wdc_format_phone( $dinner_phone ); // comes back (111) 555-9999

        $item->update_meta_data('dinner_phone', $formatted_diner_phone);

        $item->save(); // Save item

        $new_phone = $item->get_meta('dinner_phone');
        echo $new_phone; // Check that items is updated
    }
    $order->calculate_totals(); // Recalculate Order totals and save
}

应该可以。
