Zdravim som strasny laik konecne sa mi podarilo spojazdnit prihlasenie a registraciu na bezplatnom serveri.
Ak som to dal na platenu domenu prestalo to fungovat a neviem preco.
index.php
Kód:
<?php
//This will start a session
session_start();
$username = $_SESSION['username'];
$password = $_SESSION['password'];
//Check do we have username and password
if(!$username && !$password){
echo "Welcome Guest! <br> <a href=login.php>Login</a> | <a href=register.php>Register</a>";
}else{
echo "Welcome ".$username." (<a href=logout.php>Logout</a>)";
}
?>
Kód:
<?php
session_start();
//This displays your login form
function index(){
echo "<form action='?act=login' method='post'>"

if(!$connect){
