Well, "undefined index" means that you are trying to access part of an array that doesn't exist. For example:

$foo = array('one'=>1, 'two'=>2);
echo $foo['three'];

In this case, $foo['three'] is causing the notice, because the index 'three' has not yet been defined.

So try looking in the files mentioned by the message, and make sure that the array is being completely created.

Notice: Undefined index: id in /opt/lampp/htdocs/server/cms/index.php on line 22

Notice: Undefined index: id in /opt/lampp/htdocs/server/cms/functions.php on line 31

LC: Basically that means that you are trying to access something called $array['id'], which does not exist. Does line 22 contain something like if ($_GET['id'])? If so, you may want to try changing that to if (isset($_GET['id']))

Thankee, nick!

Now I just have some errors on my /cms/ index page, saying: Notice: Undefined index: id in C:\wamp\www\cms\index.php on line 22.

Any help there?

I did not think of that. That could very well be the proper solution to that problem!

you need to move the connect() function higher in the code. it needs to be before the mysql-real-escape-string function call. i put mine after the check member() call. you must be connected to a DB before you can call mysql-real-escape-string.

Hmm, still no fix.

I'm running on a localhost wamp2.0 setup.

I doubt that's the problem, as I get similar problems when I put it live on my own site.

Looks like there's a problem validating your MySQL credentials. Make sure that you have spelled the username correctly, and that you have given that user access to the database. Also, it looks like you haven't included a password. If your MySQL user is password-protected, make sure to include that as well.

I am having some trouble with creating a page, and, on my localhost version, I get tons of "Warning: mysql_real_escape_string() [function.mysql-real-escape-string]: Access denied for user 'SYSTEM'@'localhost' (using password: NO) in C:\wamp\www\cms\admin\create.php on line 14" for creating pages. I really only get 4, but still. Help, and also, I emailed you before about Wordpress.
