Cookies

modifying to create a shopping basket

[bateman_ap]

I am trying to make a simple shopping basket in taditional asp. I have created a cookie to store all the items added to the basket by referencing their uid numbers. However I need to also add the quantity of each and this is causing some problems.

At the moment the cookie looks like
uid1=1&uid2=1

I was thinking the =1 should reflect the quantity so every time a item was added with that uid it increments by 1. Also there should be a way to subtract it by 1 upon someone clicking the subtract link.

The code that currently sets the cookie is

uid = request.querystring("id")
cookieUid = "uid" & uid
Response.Cookies("short")(cookieUid) = "1"
response.redirect "shop.asp"

Anyone got an idea of how to achieve this?

Many thanks

It would be much cleaner if the cookie contained your unique shopper guid that had a one to many relationship with a basket table.

Here's a crude example:

cookie
=======
GUID.....xyz

basket sku qty
=========================
GUID.....xyz 123456 1
GUID.....xyz 987654 3

I was thinking that, reading up on a few sites some people had recommended the cookie option as it isn't putting as much stress on the server. What do you think?

I would go with the basket table. Database tables are perfect for managing this type of solution.

Just make sure you can encrypt your ID in the cookie, or at least don't tie any personal info to the ID without some security. If I choose to view the cookie you place on my computer, and I change the ID to something else, I should not be able to view anyone else's personal details.
