How do I hide my buttons "Inloggen" and "Registreren" when I am logged in? I have two seperate files; I have my index file with the menu etc and a inloggen file for the php and the form. If I am logged in I want the buttons to hide and replace it for a button with logout. How do I do that with my code?
Index:
<?php
require 'dbconnectie.php';
?>
