我正在使用phpmailer通过电子邮件发送我的表单详细信息，它具有一个名称字段和一个fil上传字段，并希望附加名称和视频并使用phpmailer通过电子邮件发送，这是我使用的示例代码。

html表格

    <form action='<?php bloginfo('template_directory'); ?>/upload.php' method='post' enctype="multipart/form-data">
          <div class="col-md-12">
            <div class="inner-addon left-addon col-md-3 col-sm-12 col-xs-12" style="display : inline-block">

          </div></div>
          </form>    

upload.php

<?php

    require __DIR__ . '/PHPMailer/PHPMailerAutoload.php';
    $name = $_POST["name"];
    $mail->isSMTP();                                      // Set mailer to use SMTP
    $mail->Host = 'smtp.mandrillapp.com';  // Specify main and backup SMTP servers
    $mail->SMTPAuth = true;                               // Enable SMTP authentication
    $mail->Username = '[email protected]';                 // SMTP username
    $mail->Password = 'password';                           // SMTP password
    $mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
    $mail->Port = 587;
    $mail->setFrom('email', 'email');
    $mail->addAddress('[email protected]', 'name');     // Add a recipient
    $mail->isHTML(true);                                  // Set email format to HTML
    $mail->Subject = $name;
    $mail->Body    = 'hi';
    if (isset($_FILES['fileToUpload']) &&
        $_FILES['fileToUpload']['error'] == UPLOAD_ERR_OK) {
            $mail->AddAttachment($_FILES['fileToUpload']['tmp_name'],
                                 $_FILES['fileToUpload']['name']);
    }            
    if(!$mail->send()) {
          error_log('Message could not be sent.');
          error_log('Mailer Error: ' . $mail->ErrorInfo);
        } else {
          error_log('Message has been sent');
    }
