A Guestbook

This example allows you to write a customizable guestbook for a Web site. A guestbook is an HTML form in which the user indicates his or her name and some comments. The guestbook can be used for collecting feedback on a topic, as a simple message board, or for submitting problems to a help desk. The data is kept in a file and can be displayed after the form is filled out; it also can be displayed on a page of its own.

Listing 18.7 provides a short bit of HTML to present a guestbook form for a fictional help desk. You can modify the form to suit your own needs, of course.
