购物网站的购物车模块问题——确认后如果把订单在另外页显示
先感谢各位前辈帮忙，本人近日正在制作一个订餐网站，在购物车模块中的遇到了一些棘手的问题，望大家帮忙~这个购物车模块是我在网上找的，修改一些数据库连接后为我所用,界面如下：
这是一个拖动式的购物车，把商品图片拖入黄色区域时就会自动把商品名加入其中，并计算总价进行显示。
右上角的“确认订单”按钮是我自己添加的，还没进行编辑，我的想法是购物车购物完毕时点击此按钮可跳转下一页面，
页面中可对已选购的商品和总价进行列表显示，可我现在不知道如何从本页面获取信息放到下页进行显示，我把本页已有的程序放到下面，希望可以得到大家的指教，最好能把我上面的想法根据我已有的购物车程序写出程序，十分感谢~~

} --------------------编程问答-------------------- 确认后一般都会将结果存在数据库中，根据订单号检索后在另外一页显示即可 --------------------编程问答-------------------- 你的订单存在哪？就从哪里取出来显示即可 --------------------编程问答--------------------
问题是由于程序不是我写的，我不知道如何获取菜单信息存入数据库中，它显示商品名和总价的控件好像不是Laber，请帮我看看程序从哪里（具体哪个控件，控件的ID）获取我需要的信息，谢谢 --------------------编程问答--------------------
这个程序应该是还没有存，好像购物车只是在cookie里临时保存，我现在就是想如何获取信息存在我的数据库中 --------------------编程问答-------------------- 参考
