无法使用PHPMailer上传和发送附件

Question

大家好，我真的很困惑。我尝试将1个字段插入一个联系表单（我从bootstrapious网站获得）上传附件并发送电子邮件。联系表单上的字段将重定向到php页面（join.php）。但不知何故，邮件可以发送但没有找到附件。下面是php代码。

<?php

require 'PHPMailer/PHPMailerAutoload.php';
// require 'phpmailer/class.phpmailer.php';

$fromEmail = 'support@test.com';
$fromName = 'My Support';

$sendToEmail = 'test@gmail.com';
$sendToName = 'Test';

$subject = 'New message from contact form';

$fields = array('name' => 'Name', 'surname' => 'Surname', 'phone' => 'Phone', 'email' => 'Email', 'message' => 'Message');

$okMessage = 'Contact form successfully submitted. Thank you, we will get back to you soon!';

$errorMessage = 'There was an error while submitting the form. Please try again later';

error_reporting(E_ALL & ~E_NOTICE);

try
{

    if(count($_POST) == 0) throw new \Exception('Form is empty');

    $emailTextHtml = "<h1>You have a new message from your contact form</h1><hr>";
    $emailTextHtml .= "<table>";

    foreach ($_POST as $key => $value) {
        if (isset($fields[$key])) {
            $emailTextHtml .= "<tr><th>$fields[$key]</th><td>$value</td></tr>";
        }
    }
    $emailTextHtml .= "</table><hr>";
    $emailTextHtml .= "<p>Best Regards,<br>Support Team</p>";

    $mail = new PHPMailer;
    $mail->IsSMTP();
    $mail->SMTPDebug = 0;
    $mail->SMTPAuth = TRUE;
    $mail->SMTPSecure = "tls";
    $mail->Port     = 587;  
    $mail->Username = "support@test.com";
    $mail->Password = "test123";
    $mail->Host     = "test.net";
    $mail->Mailer   = "smtp";
    $mail->setFrom($fromEmail, $fromName);
    $mail->addAddress($sendToEmail, $sendToName); 


    if(!empty($_FILES['uploaded_file']))
    {
        $path = "/home/mtelesol/public_html/upload/";
        $path = $path . basename( $_FILES['uploaded_file']['name']);
        if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $path)) {
            echo "The file ".  basename( $_FILES['uploaded_file']['name']). 
            " has been uploaded";
    }   
    else
    {
        echo "There was an error uploading the file, please try again!";
    }
    }


    $mail->addAttachment($path);

    $mail->addReplyTo($from);

    $mail->isHTML(true);

    $mail->Subject = $subject;

    $mail->msgHTML($emailTextHtml); 


    if(!$mail->send()) {
        throw new \Exception('Message could not be sent.' . $mail->ErrorInfo);
    }

    $responseArray = array('type' => 'success', 'message' => $okMessage);
}
catch (\Exception $e)
{
    $responseArray = array('type' => 'danger', 'message' => $e->getMessage());
}


if (!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
    $encoded = json_encode($responseArray);

    header('Content-Type: application/json');

    echo $encoded;
}
else {
    echo $responseArray['message'];
}

以下是html代码：

                    </form>

我是php和网页设计的新手。真的希望并感谢任何可以帮助我解决这个问题的人。谢谢。
