我已经尝试了我所知道的一切,但仍然无法正常工作。我无法从我的 HTML 表单中获取任何已发布的数据,并且我知道它没有从 HTML 表单中获取数据,因为我试图更改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;
}
}
?>

我已经坐在这个问题上超过 10 个小时,没有一个适当的解决方案。
