我已经尝试了我所知道的一切，但它仍然不起作用。我无法从我的HTML表单中获得任何发布的数据，我知道它没有从HTML表单中获取数据，因为我试图改变值并在没有表单的情况下执行，然后它就可以工作了。
这是我的html表单:<?php
ob_start();
session_start();
error_reporting(E_ALL);
if (!ini_get('display_errors')) { ini_set('display_errors', '1');}
include 'classes/user.class.php';
include 'classes/database.class.php';
include 'classes/config.class.php';
include 'classes/bcrypt.class.php';
if(isset($_POST['submitted'])) {
$user = new MonetizeMedia'Classes'User;
$db = new MonetizeMedia'Classes'Database;
$username = $_POST['username'];
$password = $_POST['password'];
$user->username = $username;
$user->password = $password;
if($user->createUser()) {
echo "DONE!";
}
else
{
echo "<br />An error occured while creating your account. Please try later.";
return;
}
}
?>

这个问题我已经纠结了10个多小时了，还没有一个合适的解决方案。
到底是什么不工作?无论如何，你应该重写你的createUser方法:
$username = null;
$password = null;
