oK, since my original question didn't make sense to the majority, I will explain in details. I have a membership system I made through some tutorials based on codeigniter framework. on my main page I have 3 buttons containing login, register, forgot pass, respectively. when I test the login and enter my details as a user, I still can see the login button, which makes no sense because it should be hidden in case I logged in. The same thing for other features I mentioned above.

now I was trying some way like if($_SESSION['user'] == "") { to achieve my goal, but without any success.

any idea how to do this correctly?

Thanks

}
