Hello,
I downloaded the code for "Content Management System" Ch.12 from web
http://www.wrox.com/dynamic/books/do...7582#downloads
for book "Beginning PHP, Apache, MySQL Web Development"
The program doesn't work correctly. I found a few errors, please help to solve them.
I have Windows 2000, Internet Explorer 6, IIS web server running and MYSQL4 and PHP4 installed.

The problems are:
I. (solved) in all files where you have "e-mail" word gives an error. So, I had to replace by "email" word.

II. (need you help)
in foloowing seven files my browser gives "undefined variable" errors on the lines:

1.file comment.php
line7 outputStory($_GET['article']);
line31 showComments($_GET['article'],FALSE);

2.file cpanel.php
line7 "WHERE user_id=" . $_SESSION['user_id'];

3.file compose.php
line47 if ($_SESSION['access_lvl'] < 2)

4.file admin
line19

5.file reviewarticle.php
line12 outputStory($_GET['article']);
line17 "WHERE article_id=" . $_GET['article'];

6.file search.php
line23 linewhile ($row = mysql_fetch_array($result))

7.file viewarticle.php
line6 outputStory($_GET['article']);
line8 showComments($_GET['article'],TRUE);

Please help to make program work correctly,
Thank you.

Sorry about the "e-mail" confusion. It seems the publisher did an automatic word-replace prior to publishing, and it affected the code.

In some cases, the code does not take into account that you may have error_reporting set to E_ALL. Check your php.ini file and check to see if error_reporting is set to E_ALL.

There are 3 ways to fix this problem:

1. Set error_reporting to E_ALL ^ E_NOTICE in your php.ini file.

2. If you don't have access to the php.ini file, or don't want to change it there, then you can set it at the beginning of your php page with the command:
  error_reporting(E_ALL ^ E_NOTICE);

3. You can fix the code to declare all variables that aren't already set. In the case of GET and POST variables, you'll need to check to see if they exist with isset(), then set them to a default value if isset() returns false.


Let us know if this doesn't fix your problems.

Thank you for the reply,
Could you please give me an example how to fix the code? There is a code for viewarticle.php (Ch.12) lines 6 and 8 gives error: 'article' not defined.

<?php
require_once 'conn.php';
require_once 'outputfunctions.php';
require_once 'header.php';

outputStory($_GET['article']);

showComments($_GET['article'],TRUE);

require_once 'footer.php';
?>

What is the URL for that page? Copy it from your browser and paste it here.

My guess is that you are not supplying an article id. The URL should be something like:

If the "?article=x" part is left off, you'll get an error. To prevent that in the future, you should add code to check if article was passed, and if not, either set a default or return to the page they came from.

Hello,
I found the problem why it didn't work: I had a misconfigured firewall on my computer.
Thank you.

Great :D

Glad I could help.
