Symfony Friendly Shopping Cart

What options exist for a simpl开发者_C百科e shopping cart system on Symfony? I'm looking for something that will:

1. Provide an interface for tracking items to purchase.
2. Provide shopping cart actions and templates (checkout, view cart, etc.)
3. Support Paypal.
4. Support coupon codes.

Every Symfony specific solution I've found (sfShop, symfony-ecommerce, sfShoppingCart) is out-of-date and not maintained for 1.4. Are there any other Symfony specific solutions?

If there's nothing Symfony specific, what more general systems integrate cleanly with Symfony? I'm looking for something simple. I don't need complete ecommerce solutions that provide a store, keep track of items/inventory etc. as this is only for a small, paid registration portion of a larger site.

There are no cart systems out there that work properly for 1.4 at the time being.

I am currently finishing up a cart system that does exactly what you are looking for. If you are planning on going the custom route, I may be able to help you along the way.

Good luck.

Update

I ended up creating a shopping cart plugin for symfony 1.4 and posted it open source at the symfony plugin repository.

You can get more information here.

Frontend Demo here.

Backend Demo here.

It is intended to be used by developers who are looking to build an e-commerce solution with symfony.
