Chapter 17. Managing Customers
This chapter is the second of five that
outline our winestore case study application. The scripts that are
discussed here concern the customer management processes, and include
moderately complex data entry, validation, error reporting, and
receipt scripts. The module uses most of the basic web database
application techniques discussed in Chapter 6 through Chapter 10. It also
makes extensive use of the generic winestore templates and other
reusable components that are discussed in Chapter 16.
The scripts that are discussed
perform the following functions:
- Becoming a member
-
A customer form that allows users to join the online winestore by
providing their name, address, email address, password, and other
details. The form collects mandatory and optional fields, and makes
use of all of the features of the
winestoreFormTemplate class discussed in Chapter 16.
The customer form is based on the phonebook details insert example in
Chapter 8.
- Updating customer details
-
A customer form that allows users to update the details they provided
when they joined the online winestore. This functionality is
integrated into the script used for becoming a member, and is based
on the phonebook details update example in Chapter 8.
- Checking customer details
-
The complete validation and database management processes for
updating and creating new customers. These processes extend the form
processing techniques introduced in Chapter 8
by applying the validation techniques from Chapter 9. The process includes creating and storing
passwords using the encryption techniques discussed in Chapter 11.
- Providing a customer receipt
-
A receipt page that presents the results of the customer membership
processing and avoids the reload problem discussed in Chapter 6.
