?– INTRODUCTION xxv
Chapter 16: Managing Customer Details
In the first two stages of development, you??™ve built a basic (but functional) site and hooked it
into PayPal for taking payments and confirming orders. In the third section of this book, you??™ll
take things a little further. By cutting out PayPal from the ordering process, you can gain better
control as well as reduce overhead. This isn??™t as complicated as you might think, but you must
be careful to do things right. Chapter 16 lays the groundwork by implementing a customer
account system, as well as looking into the security aspects of exchanging and storing customer
and credit card details.
Chapter 17: Storing Customer Orders
In Chapter 16, we added customer account management capabilities, and we??™re now securely
keeping track of customer addresses and credit card information.
