上下文：该页面用于将菜单项输入到订单中。当按下菜单项按钮时，来自产品＆＃39;的数据。查询表格并将其插入到“订单项目”中。表。我还想按下相同的按钮来获取服务大小值（theProducts.dbProdServing）并从产品的库存（theInventory.dbInventoryAmt）中减去该金额，并相应地更新该表。
我遇到的问题是试图弄清楚如何按下一个按钮同时执行两个带有绑定值的预准备语句，这些是将产品数据插入＆＃39; theOrderItems＆＃39的声明;表和UPDATEs＆＃39; theInventory＆＃39;表
目前，页面运行INSERT语句正常，但UPDATE语句根本不运行。
有三个页面可以处理整个订单系统，＆＃39; insertOrder.php＆＃39;打开订单，＆＃39; insertOrderItem.php＆＃39;允许将商品添加到特定订单，并且＆quot; completeorder.php＆＃39;只显示总订单。我只会发布前两页。
