I am trying to add a shopping cart to our family business web site.
I have found a very nice east script that works very nicely, but it stops at the Shopping Cart.
It is written in PHP and MySql.
It has no facilities to send an order via email, or to send the order via Paypal.
I'm not bothered about Paypal, at the moment, but I do need to get the order via email.
There is a lot to setting up a cart. I'm not sure how this one is meant to work, but if you are collecting credit card details, you need to take security measures like getting an SSL certificate. You may be better off sing something like PayPal, which is much easier, or a fancier third party service like FoxyCart. Or you coud host your whole site at something like Shopify.
