Pay online service

I have a database where you can select articles etc, users have an account, it's all in mysql and php (i guess you don't need that code). What i was wondering was how to write a script that allows users to pay online for the articles they selected? It doesn't need to be any code, just ideas / hints / tips / ... (that are doable in PHP or something similar开发者_StackOverflow社区) Thanks in advance!! -Samuel

You have to do that through a service that collects money, such as paypal or a bank.

You make an account there, and they will provide the necessary files and documentation to do that.

Usually it will mean

1. when the user wants to pay, you redirect them to a specific page in the payment site
2. you host an IPN (Instant Payment Notification) file where that site will contact you when he receives a payment

I've done some paypal coding before and it is easy to set up, suggest that you should search for payment gateway that, i've work with ipay88.com before its one of payment gateway at my place.

Usually if you setup the paypal for the business transaction you will need to register as merchant account and they will charge you per transaction, same goes with payment gateway.

It is a very broad question. But basically you need to integrate some payment module, such as paypal. Look at their website, where there are tutorials on how to get it working with php.
