Question

我使用PHPmailer发送邮件。

$mail = new PHPMailer();
$mail->CharSet = 'UTF-8';
$mail->From      = 'some address';
$mail->FromName  = 'some name';
$mail->Subject   = 'some subject';
$mail->Body      = $bodytext;
$mail->IsHTML(true); 
$mail->AddAddress('some email');

// FILES
for($i = 0; $i < $length; $i++) 
{
    $filedata['name'] = $_FILES['userfile']['name'][$i];

    $path = "somepath";     
    move_uploaded_file($_FILES['userfile']['tmp_name'][$i], $path);
    {    
        $stmt = $pdo->prepare("INSERT...");
        $stmt->execute($filedata);

        $mail->AddAttachment( $path, $filedata['name']);
    }
}

$mail->Send();

问题是，有时（并非总是）附件不包含在电子邮件中，而是总是上载到服务器并添加到数据库中。

出什么问题了？可能是在addAttachment时刻move_uploaded_file还没有完成上传吗？

您需要检查文件是否已正确上传，文件是否为空以及PHPMailer是否可以加载文件。

改写the PHPMailer example：

try {
    for ($i = 0; $i < $length; $i++) {
        if ((int)$_FILES['userfile']['size'][$i] === 0) {
            throw new RuntimeException('Zero length file; may exceed allowed size.');
        }
        $uploadfile = tempnam(sys_get_temp_dir(), hash('sha256', $_FILES['userfile']['name'][$i]));
        $filename = $_FILES['userfile']['name'][$i];
        if (!move_uploaded_file($_FILES['userfile']['tmp_name'][$i], $uploadfile)) {
            throw new RuntimeException("Failed to move file $filename to $uploadfile");
        }
        if (!$mail->addAttachment($uploadfile, $filename)) {
            throw new RuntimeException("Failed to attach file $filename");
        }
        //Everything is ok, so do whatever else you need to do, like store the record in the DB
    }
} catch (RuntimeException $e) {
    echo 'File upload failed:', htmlspecialchars($e->getMessage());
}

有时不包括PHPmailer附件
