自定义PHP邮件程序附件未随电子邮件附上

我有自定义邮件功能，其中除了文件附件，其余的东西都工作得很好。为了简化，我只添加了与附件相关的代码。作为输出，我可以看到上传到服务器的文件，但它将附加在电子邮件中。我在电子邮件中得到除文件附件以外的所有详细信息。这是自定义邮件类，我已经创建了，但不知道为什么附件不发送到电子邮件

Mailer.class.php

<?php
class Mailer 
{

private $addAttachment = [];

public function addAttachment($addAttachment)
    {   
        if (empty($addAttachment))
        {
            $this->setError('No Attachments','empty');
        }else{
             $this->addAttachment[] = $addAttachment;
             echo $addAttachment;
        }
        return $this;
    }
}

您使用的是哪个版本的PHPMailer？@Martin我在日志中没有看到任何错误上传的文件是否确实存在于指定位置；根据

move\u uploaded\u file（）

？@Martin的设置，它完全是定制的PHPMailer，我没有现在添加的addattachment功能。

echo$addattachment这看起来不合适
require_once 'Mailer.class.php';

$toemails = array("my_email_address@gmail.com"); 
$toemail = implode(',', $toemails);

if ($_SERVER["REQUEST_METHOD"] == "POST") {

    $attachment = $_FILES["uploaded_file"]["tmp_name"];
    $folder = '/uploads/';
    $file_name1 = $_FILES["uploaded_file"]["name"];
    move_uploaded_file($_FILES["uploaded_file"]["tmp_name"], "$folder".$_FILES["uploaded_file"]["name"]);

    print_r($_FILES);
    $mailer = new Mailer(true);

    $mailer->setToEmail($toemail)
               ->setFromName(isset($_POST['fname'])?$_POST['fname']:'')
               ->setFromEmail(isset($_POST['email'])?$_POST['email']:'')
               ->setSubject('Application Regarding'.$_POST['Title'])
               ->addAttachment('/uploads/'.$_FILES["uploaded_file"]["name"])
               ->setBody($body)
               ->run();
                exit();

        if(!$mailer->sendMail()) {
            echo "Something has gone wrong, please contact the site administrator or try again.";
        } 
        else {
            echo "Email Successfully Submitted"; 
        }

        print "</pre>"; 
    }
?>
