Question

我正在使用PHPMailer发送带有可选附件的电子邮件。发送带有附件的电子邮件时，此方法工作正常。但是问题是PHPmailer在附件为空时拒绝发送电子邮件，有任何解决方法吗？

<?php

use PHPMailer\PHPMailer\PHPMailer;

$msg = '';
$sender_name =  $_POST['sender_name'];
// Upload handled successfully
// Now create a message
require 'vendor/autoload.php';
$mail = new PHPMailer;
$mail->setFrom('info@*****.com', 'first last');
$mail->addAddress('info@*****.com');
$mail->Subject = 'PHPMailer file sender';
$mail->Body = "Contact form submission:\n" . "Name: $sender_name\n";

if (array_key_exists('userfile', $_FILES)) {
    // First handle the upload
    // Don't trust provided filename - same goes for MIME types
    // See http://php.net/manual/en/features.file-upload.php#114004 for more thorough upload validation
    $uploadfile = tempnam(sys_get_temp_dir(), hash('sha256', $_FILES['userfile']['name']));
    if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {

        // Attach the uploaded file
        //$mail->addAttachment($uploadfile, 'My uploaded file');

        $name = $_FILES['userfile']['name'];
        $ext = end((explode(".", $name)));
        $mail->addAttachment($uploadfile, 'You Have Attachment.'.$ext);


    } else {
        $msg .= 'Failed to move file to ' . $uploadfile;
    }
}

if (!$mail->send()) {
    $msg .= "Mailer Error: " . $mail->ErrorInfo;
} else {
    $msg .= "Message sent!";
}
?>

这是位于PHP代码下的html女巫：

<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>PHPMailer Upload</title>
</head>
<body>
<?php if (empty($msg)) { ?>

    <form method="post" enctype="multipart/form-data">
        <input type="hidden" name="MAX_FILE_SIZE" value="1000000">
        <br>
        <input type="text" name="sender_name">
        <br>
        Send this file: <input name="userfile" type="file">
        <br>
        <input type="submit" value="Send File">
    </form>

<?php } else {
    echo $msg;
} ?>
</body>
</html>

Answer 1

您整个脚本的实际发送位置取决于是否存在文件yes或no。这由脚本顶部的if语句处理。我建议进行编辑，以便始终发送电子邮件，并且仅在文件为是或否时才添加文件。但是由于我在移动设备上，所以我不知道编辑建议是否通过。

我会重写它，就像这样：

    // Now create a message
    require 'vendor/autoload.php';
    //$mail->AllowEmpty = true;
    $mail = new PHPMailer;
    $mail->setFrom('info@*****.com', 'first last');
    $mail->addAddress('info@*****.com');
    $mail->Subject = 'PHPMailer file sender';
    $mail->Body = "Contact form submission:\n" . "Name: $sender_name\n";

    if (array_key_exists('userfile', $_FILES) && $_FILES["userfile"]["error"] == UPLOAD_ERR_OK) {
        // First handle the upload
        // Don't trust provided filename - same goes for MIME types
        // See http://php.net/manual/en/features.file-upload.php#114004 for more thorough upload validation
        $uploadfile = tempnam(sys_get_temp_dir(), hash('sha256', $_FILES['userfile']['name']));
        if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
            // Upload handled successfully
            // Attach the uploaded file
            //$mail->addAttachment($uploadfile, 'My uploaded file');

            $name = $_FILES['userfile']['name'];
            $ext = end((explode(".", $name)));
            $mail->addAttachment($uploadfile, 'You Have Attachment.'.$ext);
        } else {
            $msg .= 'Failed to move file to ' . $uploadfile;
        }
    }

    if (!$mail->send()) {
        $msg .= "Mailer Error: " . $mail->ErrorInfo;
    } else {
        $msg .= "Message sent!";
    }

通过这种方式，它将发送电子邮件，并且如果有文件附件，它将包含在内。

它是这样工作的，现在它发送带有/不带有附件的电子邮件，我还更改了许多内容，例如发件人姓名和电子邮件，将其作为变量和正文内容。现在，我没有任何PHP错误，并且该表单可以按我希望的那样完美地工作，我希望这会对某人有所帮助，谢谢大家。

<?php

use PHPMailer\PHPMailer\PHPMailer;

$msg = '';
if (array_key_exists('userfile', $_FILES)) {
    require 'vendor/autoload.php';
    // Create a message
    $mail = new PHPMailer;
    $mail->SetFrom($_POST['email'], $_POST['sender_name']); //altered
    $mail->addAddress('info@***.com');
    $mail->Subject = 'Service Request';
    $mail->Body = "Sender: " .$_POST['sender_name'] ."\n" ."Phone: " .$_POST['phone']; //altered
    //Attach multiple files one by one
    for ($ct = 0; $ct < count($_FILES['userfile']['tmp_name']); $ct++) {
     $uploadfile = tempnam(sys_get_temp_dir(), hash('sha256', $_FILES['userfile']['name'][$ct]));
     $filename = $_FILES['userfile']['name'][$ct];
       if (move_uploaded_file($_FILES['userfile']['tmp_name'][$ct], $uploadfile)) {
          $mail->addAttachment($uploadfile, $filename);
        } 
    }
    if (!$mail->send()) {
        $msg .= "Mailer Error: " . $mail->ErrorInfo;
    } else {
        $msg .= "Message sent!";
    }
}
?>
