i need a very basic PHP based cookie-less shopping cart that doesnt use databases and works with Windows IIS. I dont have database support on my site so the cart cant use databases, but it can use flat-text file databases if it has to.
i am currently using a javascript based shopping cart called NOP CART available at www.nopdesign.com/freecart but the problem is i cannot use it anymore as alot of my customers are students and they use college computers to order, and alot of colleges turn off their cookies and as a result my customers cannot order and receive alot of emails saying their shopping cart shows empty.
any help would be very much appreciated.
many thanx
cheers

That or you could pay a programmer to give you a hand.
like mat says - you got to get your hands dirty and do some coding - if you use other people's code you end up spending longer getting your code to work with theirs and their code to do what you want not what they wanted than you would have ever spent writing what you needed straight off - and you'd still have worries about security and capability which you'd not have if you had coded it by hand.
Plan A was to have a php solution, but I'm ending up having to use a javascript/php combination (Plan B) until I get more experience with php, sessions, and arrays.
I had a link to something to post but it's Perl and I just noticed it's also for Unix... If I run across anything, I'll post here.
Good luck.
but problem with cartman is it uses cookies and doesnt support shipping costs. the good thing about cartman is that it does not requires third-party database-systems, such as MySQL.
if anyone has any suggestions, plzzzzz let me know.
many thanx in advance

Not 100% verified but seems to work ok at

You can write the checkout, I'm beat.
"Kind Of" reminds me of doing Pascal homework for favours in col ;-) Good 'ole days i reckon.

[edit reason] no urls thanks [/edit]
there seems to be one problem with the code though. When i try the one at <snip> that works, but my one doesnt fully work. in my one, when i add the item to the cart it says its been added but then when i click on view it says bag is empty.
Any ideas? could it be coz i am using PHP4 on IIS? if so how can i solve the problem?
I will sort out the checkout bit my self somehow, but the main thing is for me to get the adding to cart working.
many thanx in advance.

you need to make sure that your web server process has permission to write to the "carts" directory.
you may wish to move the "carts" directory somewhere outside of the web root to avoid a security issue.
take care,
