请帮助我，我通过mylaptop上的composer安装了PHPMailer，并将同一文件夹上传到远程服务器。我按如下所示设置表单参数和php代码，但我不知道为什么表单未提交？ 它将清除表单，即使我设置了错误消息，它也不会放入电子邮件中，甚至不会显示任何错误。
是我需要与托管公司联系还是在下面的脚本中犯了一个错误？
<?php
// Import PHPMailer classes into the global namespace
// These must be at the top of your script, not inside a function
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
// initialize the $message variable
$message='';
if (isset($_POST['submit'])) {
$issues='';
foreach($_POST["issues"] as $row)
{
$issues .= $row . ', ';
}
$issues = substr($issues, 0, -2);
$path = 'upload/' . $_FILES["photo"]["name"];
move_uploaded_file( $_FILES["photo"]["tmp_name"], $path);
$message = '
