php shopping cart api

i was wondering if there is an API for a shopping cart (PHP). I have looked at solutions like opencart etc, but i have my own design and i just need some kind of API which i can use and add the shopping functionality directly into my website.

I was thinking like ExternalCart->createNewProduct(...); or ExternalCart->showProductInfo(...); or ExternalCart->addCategory(...)

So the backend is handled by开发者_开发问答 the API and i could just use the output and show it whichever way i want to, hence, not being stuck with the shopping cart's layout or functionality.

Any suggestions?

thanks

Since you have your own design - go with a fully JS solution - Simple Cart - there is no need for a backend.

<a href="javascript:;" onclick="simpleCart.add( 'name=Awesome t-shirt' , 'price=35.95' , 'quantity=1' );">Add To Cart</a>

Railskits has a cool Paypal API (but it's Ruby) -- and doesn't really have cart or order fulfillment.

I've heard ZenMagick has an API wrapping ZenCart, but their demo site seems broken, so that doens't inspire confidence.

I think the best option is to "convert" your site to OpenCart. You can use the its theme system to achieve that. You can read about it here http://www.opencart.com/index.php?route=documentation/documentation&path=43_44 as its build over MVC architecture and uses CSS, it shouldn't be very hard to adapt. :o)

Moltin might be worth looking into. There is a cart section in their API amongst other ecommerce components. You can use whichever pieces of the ecommerce system that you need. Here's the documentation
