1. The $domain code is actually just a unique naming code for your cookies. You just need to put any name. It could be Olive, code, random, or anything you like. It doesn't affect the pages and operation much.

2. These files are all currently linked together as being in the same directory. They don't have to be in the root but they have to be in the same folder. You can move them around but you'll have to change the file pointing to them.

3. You can link to the login from sub directories or have the login in a sub directory and link back. You'll have to change the path to the files though such as the login and logout php pages.

Hope that helps!

Thank you very much for the code.

I have some few questions to ask as below :

1. $domain_code = 'website'; Should I have to put the url of the page which I want member to login before they can redirect to protected page, right? (in easy word, I mean the page that contain login form)

2. Do these code need to be in root folder?

3. Is it possible if I would like these codes along with my other protected php pages located together in sub directory? Do I need to change any code inside?

Thank you for your kind reply.

The $domain_code is merely for making cookies save unique to your website only. It won't change anything in the equation. I suppose its your login redirect that is having problem or is it he log out? Are there any error messages being outputted?

The only change is to the line : header("LOCATION: PDPform.html"); to reflect the name of the file I want to go to.

Does the value of the domain code in _login_users.php have any bearing?

I was wondering if you made any changes to the code. The redirection will only work before any HTML code is outputted.

Thanks.
