[求助]购物车问题
请各位兄弟姐妹帮帮忙，我做的购物车只是实现了购物的功能．而当不同的用户进入购物时，用的都是一个购物车，若想不同的用户拥有自己的购物车，该怎样实现？

下面是购物车的代码,其中plist.asp是将用户选购商品的ID添加进商品列表中. <%@ LANGUAGE="VBSCRIPT" %> <!--#include file="plist.asp" --> <!--#include file="connections/xue.asp" --> <% strspbh = Request("spbh") if ((len(trim(strspbh)) = 0) or (strspbh = "undefined")) then strCheck = "no" end if
ProductList = Session("ProductList") Products = Split(Request("spbh"), ", ") For I=0 To UBound(Products) shangpin Products(I), ProductList Next Session("ProductList") = ProductList
Head="您所选购的商品如下" ProductList = Session("ProductList") If Len(ProductList) =0 Then Response.Redirect "nothing.asp" response.end end if
If Request("MySelf") = "Yes" Then ProductList = "" Products = Split(Request("spbh"), ", ") For I=0 To UBound(Products) shangpin Products(I), ProductList Next Session("ProductList") = ProductList End If If Len(ProductList) = 0 Then Response.Redirect "nothing.asp" response.end end if set rs=server.createobject("adodb.recordset") sql = "Select * From Product" sql = sql & " Where Product_Id In (" & ProductList & ")" rs.open sql,conn,3,3 %> <html>
