Now, I have following e-commece application scenario:
1. I have one web site designed for selling one specific software product;
2. There is a form in the page which is used for input contact email, mobile,addr,quantities information;
3.If people are intersted in the product, he will input above information and click submit;
4.The order will be printed on the screen with another button named:pay for this order;
5.After that, the order information including money number, order id will be transfered to the payment gateway(Third party, alipay in china, similar to paypal)in a formatted manner;
6. The alipay handle the payment and will notify my site.
I have couples of questions on above steps:
In the step 5. how can I "store" step 3 inputed information?
How can I transfer that to alipay(paypal)?Can you give more alternative solutions to address this requirement?
Can you give a detail technical description on those steps what happened during those steps?
