尝试：
if (isset($_FILES['uploaded_file']) && $_FILES['uploaded_file']['error'] == UPLOAD_ERR_OK) { $mail->AddAttachment($_FILES['uploaded_file']['tmp_name'], $_FILES['uploaded_file']['name']);}基本示例也可以在找到。
函数定义为
AddAttachment：
public function AddAttachment($path, $name = '', $encoding = 'base64', $type = 'application/octet-stream')
