自定义 Woocommerce create_order api 修改

Question

我在 wordpress woocommerce 中创建了自定义 create_order() api 函数。但我意识到它只接受非动态的单一产品。目前如果我有一个产品id 1 ~ 5 (单一产品) 6 到 10 是可变产品，这段代码每次只会添加一个产品。

如何更改我的代码，以便它能够添加 MULTIPLE 种不同的 kinds/groups 产品？是否是单一产品或可变产品或将产品捆绑为 1 个订单？

对不起我的英语不好:)

$order = wc_create_order();
                if (count($products)) {
                    foreach ($products as $key => $value) {
                        if ($value['variation']) {
                            $product = new WC_Product_Variable($value['id']);
                            $product->variation_id = $value['variation'];
                            $variation = $product->get_available_variations();
                            foreach ($variation as $key2 => $value2) {
