John Conde's Blog: Handling Online Payments With PHP And Authorize.Net
Note: This article was originally published at PHPDeveloper on 13 December 2011.
As an Authorize.Net blogger, I decided to write a series of articles that outlined not only the basics of handling an ecommerce transaction, but also included some best practices as well. These were demonstrated using a web-based payment form that when complete forms a real-world, production ready solution. Since there was a lot of ground to cover, I broke the tutorial into eleven parts.
Parts of the series cover topics like:
- reading/sanitizing data
- handling validation errors
- preventing duplicate submissions
- preventing automated form submissions
