spl_autoload_register(function($class) {
    require_once 'classes/' . $class . '.php';

});

require_once 'functions/sanitize.php';
?>

Answer 1

The button was not closed

you have

<input type="submit" value="Register"

should be

<input type="submit" value="Register">

More over the form needs to be closed

</form>

Also You have form action="" this will need $_GET["username"] etc to get the values In the function exists() default type is post so u will need to set the form method as post or while calling the

if(input::exists()) {
echo 'Submitted';
}

you should do as

if(input::exists("get")) {
echo 'Submitted';
}

So in the 2nd case you can keep the form action as ""

Answer 2

i found the problem

<form action="" method=""> 

forgot to put post in it

<form action="" method="post">
