我的 PHP 邮件程序代码给出了 HTTP 500 错误

Question

我为一个使用普通文本框、下拉选项框、日期日历、复选框和附件的网站编制了一份详细的申请表。我只使用普通的 PHP 就获得了精美的电子邮件表单，但在处理附件部分时我被卡住了。然后，我学会了最好地使用 PHP Mailer，所以我为此重新使用了 PHP，但得到了可怕的 HTTP 500 错误。请有人检查我的代码，看看我哪里出错了。非常感谢您。

<?php
use PHPMailer\PHPMailer\PHPMailer;

function clean_text($string)
{
$string = trim($string);
$string = stripslashes($string);
$string = htmlspecialchars($string);
return $string;
}

if(isset($_POST["submit"]))
{
$path = 'href="/upload/"' . $_FILES["attachment"]["name"];
move_uploaded_file($_FILES["attachment"]["tmp_name"], $path);

现在一切都已修复并像梦一样工作。 问题是，我正在处理的站点位于“临时”文件夹中，以免破坏旧站点。我在子目录中有 PHPMailer 和 Upload 文件夹，而不是服务器的主目录，所以这就是它需要的方式 -

require "/home/awolpm/PHPMailer/src/Exception.php";
require "/home/awolpm/PHPMailer/src/PHPMailer.php";

这行也不需要 -

 require 'class/class.phpmailer.php';

上传文件夹需要是 -

$path = '/home/awolpm/upload/"' . $FILES["attachment"]["name"];
move_uploaded_file($FILES["attachment"]["tmp_name"], $path);

肯定让我挠头了！

为此做的最后一件事 - 在发送成功时弹出一个模式框并向发件人返回确认电子邮件。
