Hi daviddawn,
Thanks for you quick reply and advice. Here is the code for add_page.php. I was able to follow the tutorial in the book until this point. Then, when I uploaded this file, the form would show up and I cannot see what is wrong. I uploaded it as is from the author's source files:
?php
// This page is used by an administrator to create a specific page of HTML content.
// This script is created in Chapter 5.
// Require the configuration before any PHP code as the configuration controls error reporting:
require('./includes/config.inc.php');
// If the user isn't logged in
