Woocommerce，付款成功，运行 SQL 命令和电子邮件

Question

我想为我的搜索找到一个正确的解决方案。我使用 Woocommerce，我创建了 5 个产品，包括 3 个专用虚拟产品。 这是这些产品的 id “产品 1” = #id23、“产品 2” = #id24 和 “产品 3” = #id26 我希望在订单付款成功后，脚本（将包含在我的子主题的 functions.php 中）分析我的订单，如下所示：

例如，如果买家购买了 x2 数量的“产品 1”，该脚本将运行该脚本两次，就像在数据库中添加一些内容（如自动生成的密码、随机序列号、日期、姓名产品，元信息...）。 请注意：循环两次的信息必须不同，尤其是密码，例如序列号） 并且买方必须购买“产品 2”，脚本必须再次运行....

所以如果你理解我的意思，这个脚本必须运行 n 次，包括带有 id（id#23、id#24、id#26）的产品及其数量。

这是一段合乎逻辑的代码（不起作用），因为我在寻求帮助；）

代码已更改/更新但不起作用:(
