PHPmailer

Question

我有一个 HTML 表单将索引传递给另一个表单，该表单创建必要的变量，然后将其插入到 PHPMailer 中。其中一个选项是浏览到一个文件，然后将其附加到电子邮件中。我遇到的问题是，如果没有要附加的文件，（那么 $file1 变量有 "no value"）PHPMailer returns 邮件无法发送的 eoor 如下 - 指向目录文件的存储位置。无法发送消息。邮件程序错误：无法访问 file: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

Answer 1

您可以简单地添加附件（如果有）。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');
}

正如评论中提到的 IncredibleHat，您还可以使用条件 is_file($path) 来检查文件路径，例如 PHPMailer itself:

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

如果你想使用路径上指定的相同内容，你也不需要指定 name。如果 name 参数为空字符串，PHPMailer 正在使用 the basename of the path。

PHPmailer - 如果附件的变量 $file1 没有值，则发送失败

PHPmailer - failing to send if variable $file1 for attachment does not have a value
