Currently I am working on a shopping cart project. Instead of reinvent the wheel, I would prefer using some existing project as starting point. So, I have done some research on it. So here is what I found
gocart
tomotocart
heroframework
They are based on codeigniter , however, I found only gocart is useful as the structure is comparatively more simple and easier to customize with. But the latest version is still bootstrap 2 only.
So , I wonder are there any similar project that can choose from, also, if I need to upgrade from bootstrap2 to bootstrap 3, does it mean I need to rewrite page by page ? Or are there any tool available to help the syntax conversion? Thanks
