Hi do you know an existing ecommerce application made with yii that has the following?
Main requirements are:
Simple to have multiple languages (on same and on different domains)
Some basic ecommerce functionality (shopping cart, payments, Paypal integration, promotions)
Welcome to the forum!
I have no information about existing ecommerce, but developing one with Yii is not hard at all:
Multiple language is supported
Sopping cat is nothing of difficoult to develop
Paypall and credi card integration are nothing of special
In my experience, you will never find anything of satisfactory already done, you will waste lot of time hacking some platform while you could get the result you want with a bit of developing.
