I'm having problems with browsers and cookie, the thing is the cookies arnt liked by the users browser unless they turn their cookies down in Internet Options > Security.

Do cookie names have to be a specific way or do you have to do something so Internet Browsers accept these cookies?

Cookies are incredibly unreliable. As you have noted, most browsers are set high enough to not accept them and the people who do accept them have become computer savvy enough to know they should clean cookies (and other things) on a regular basis.

Unless you're just looking to add basics for returning visitors (such as "welcome back username"), I'd look for another solution to track returning visitors.

Just my TWO cents. :-)

A good method would be IP address though, like cookies this has its fault to. As many ISPs have dynmic IP addresses for clients, it will record thier IP but it would only work if that user has the same IP every time.

I have a login system with cookies

You need to be using sessions for your login system, not cookies. The only way a cookie relates to a login system is possibly auto filling the user/pass -or- auto logging returning customers (if they accepted your cookies, just like webmaster-talk.com does).

Your login page will look "similar" to this:

session_start();
if ($login) {
$valid_user = $username;
session_register("valid_user"); }

On any pages you want protected by login, just add this at the top of the page:

session_start();
if (!session_is_registered("valid_user")) {
header("Location: login.php"); }
Content for logged people will go here.

Realize this is a very basic sample. I'd do some reading on sessions.
