我正在使用 PHPMailer 发送带有可选附件文件的电子邮件。当发送带有附件的电子邮件存在时，这工作正常。但问题是当附件为空时，PHPmailer 拒绝发送电子邮件，有什么解决办法吗？<?phpuse PHPMailer\PHPMailer\PHPMailer;$msg = '';$sender_name = $_POST['sender_name'];// Upload handled successfully// Now create a messagerequire 'vendor/autoload.php';$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>

我会重写它，变成这样：
// 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!";
}
这样它将发送电子邮件，如果有文件附件，它将被包含在内。

它以这种方式工作，现在它正在发送带/不带附件的电子邮件，我还将发件人姓名和电子邮件等许多内容更改为变量和正文内容。现在我没有收到任何 PHP 错误，并且表单按照我的意愿完美运行，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!";
}
}
?>

完成实际发送的整个脚本取决于是否有文件是或否的事实。这是由脚本顶部的 if 语句处理的。我建议在始终发送电子邮件的地方进行编辑，并且只有在有文件是或否时才会添加文件。但由于我在移动设备上，我不知道编辑建议是否通过。
