Question

我有一个HTML表单，它将索引传递给另一个表单，这会创建必要的变量，然后将这些变量插入到PHPMailer中。其中一个选项是浏览到随后附加到电子邮件的文件。我遇到的问题是，如果没有要附加的文件，（然后$ file1变量具有“无值”）PHPMailer返回消息无法发送的内容，如下所示 - 指向存储文件的目录。无法发送消息。邮件程序错误：无法访问文件：C：/ wamp64 / www / CIA / PODS /

$mail = new PHPMailer(true);                              // Passing `true` enables exceptions
try {
//Server settings
//$mail->SMTPDebug = 2;                                 // Enable verbose debug output
$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'mail.smtp2go.com';  // Specify main and backup SMTP servers
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = 'xxx@xx-xxxxxx.co.za';              // SMTP username
$mail->Password = 'xxxxxxxx';                         // SMTP password
$mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
$mail->Port = 2525;                                    // TCP port to connect to
//Recipients
$mail->AllowEmpty = true;
$mail->setFrom('admin@ic-express.co.za', 'ICExpress Waybill Updates');
$mail->addAddress('xxxx@xx.co.za'); 
$mail->addAddress($email);  
$mail->addReplyTo('xxxx@xx.co.za');
$mail->addCC($addemail);
$mail->addCC($addemail2);

echo $file1;
$path=$_SERVER['DOCUMENT_ROOT'].'/CIA/PODS/'.$file1;
$name=$file1;
$mail->AddAttachment($path,$name,$encoding ='base64',$type = 'application/octet-stream');
$mail->AllowEmpty = true;
$mail->isHTML(true);                      // Set email format to HTML
$mail->Subject = $subject ;
$mail->Body    = <<<END

如果附件可用，您只需添加附件即可。如果没有文件附件，请不要尝试添加附件：

$path = $_SERVER['DOCUMENT_ROOT'].'/CIA/PODS/'.$file1;

if (is_dir($path) === false && file_exists($path)) {
    $name = $file1;
    $mail->AddAttachment($path, $name, $encoding = 'base64', $type = 'application/octet-stream');
}

正如IncredibleHat在评论中也提到的那样，您也可以使用条件is_file($path)来检查PHPMailer itself之类的文件路径：

if (is_file($path)) {
    $mail->AddAttachment($path, '', $encoding = 'base64', $type = 'application/octet-stream');
}

如果您想使用路径中指定的相同内容，也不需要指定name。如果name参数是空字符串，PHPMailer正在使用the basename of the path。

PHPmailer - 如果附件的变量$ file1没有值
