changing the login logout division

[colap]

For example: this phpfreaks forum,

If i login the login textboxes are gone and from navigation menu we have logout and other extra menus.

 

How would i do this?

 

Do i have to load whole new page or do  i have to use Ajax to implement this?

I would add if statements, like if someone is logged in with the session username, then echo this, if the person is logged out or not logged in then echo something else like a register or login link.

Do you mean a new page will be loaded with new "echo <a href="" >..." if someone is logged in other nothing will happen.

 

Is it?

session_start();
if( $_SESSION['hasLoggedIn'] == 1 ) {

    echo 'Hello ' . $_SESSION['username'];

}else{

    echo 'Please login';
    //login form

}
