concept of shoppin cart thanks

[melnet]

hi

when user add some items into shopping cart, what method should i choose?

Session("OrderProduct") = Session("OrderProduct") & "[" & productid & "(" & qty & ")]"

means that
Session("OrderProduct") =
Session("OrderProduct") & [ProductName_A(9)][ProductName_B(20)][ProductName_C(1)]

but i am afraid some product name will be duplicated.
so i did
Session("OrderProduct")[ProductName_A_10000001(9)][ProductName_B_10000002(20)][ProductName_C10000003(1)]

*ProductName_A_10000001, 10000001 is product id.

if id is 10000001, coz the id is long. i think id and qty will have no error.

however if [ProductName_B_10000002(1)] changes to [02(1)], there have a error.

i hope guys understand what i write.

any good methods to me for refer!?

thanks a lot.

personally with shopping carts i like to use a shopping cart table in a DB, and in combo with cookies, the user's stuff will still be there for them should they return to the site ( with a SP that removed over a week/month old cart contents ) but the nice part with the DB/Table combo is you can just request if that item is in cart, if it is, +1 if not, add it.

and opposite is true for removing items, -1 or delete.

I agree with Robert. Do not use sessions, store the data in a database and then store the Order_ID (or whatever unique identifyer you will use) in a cookie. I have done this a few times and it works well.
