Hi

So I haven't created an ecommerce site before, and can't quite get my head around how the website, cart, and paying system integrate together.

I can work with HTML, PHP and MySql.

My thoughts on how this works ideally, is that I have all my products with their ID's, descriptions, Prices and quantities etc all on my Sql database.
The cart somehow attaches on..?
And then the paying system, e.g. paypal paying service somehow attaches on..?

What it looks like to me though is that I have to input all my product details into the cart system (not on my database).


I will be getting weekly updates of a product list of lots of items, which i imagine will be easy to upload to my database, but not so easy to upload to a cart service.

Is this possible the way I would like to do it?

What are your recommendations?

Thanks
Ryan
