This technology is called AJAX, and
it allows you to make your web applications easier and more pleasant to use for your visitors.
Chapter 14: Accepting Customer Orders
The good news is that the brand-new shopping cart implemented in Chapter 12, and then
AJAXified in Chapter 13, looks good and is fully functional. The bad news is that it doesn??™t
allow the visitor to place an order yet, making it totally useless in the context of a production
system. As you have probably already guessed, you??™ll deal with that problem in Chapter 14, in
two separate stages. In the first part of the chapter, you??™ll implement the client-side part of the
order-placement mechanism. In the second part of the chapter, you??™ll implement a simple
order administration page where the site administrator can view and handle pending orders.
Chapter 15: Product Recommendations
One of the most important advantages of an Internet store, compared to a brick-and-mortar
location, is the capability to customize the web site for each visitor based on his or her preferences
or on preferences based on data gathered from similar visitors. If your web site knows
how to suggest additional products in a clever way, your visitors might end up buying more
than initially planned. You have undoubtedly already seen this strategy in action on many successful
e-commerce sites, and there is a reason for that??”it increases profits.
