我想通过刷新页面来停止垃圾邮件联系表单的功能。是的，我尝试了这里提到的几种方法来避免这种情况，但它没有用。好吧，部分工作。我使用$ _POST并指向表单上的同一页面（index.php）将其重定向到同一页面，然后打印成功或错误消息。我设法修复了刷新垃圾邮件的事情，但后来我也失去了成功/错误消息。帮助我解决它，以便您不能通过刷新页面垃圾邮件，仍然看看邮件是否成功发送。这是我的代码：
<?php
if(isset($_POST['submit']))
{
$message=
'Full Name: '.$_POST['fullname'].'<br />
Subject: '.$_POST['subject'].'<br />
Phone: '.$_POST['phone'].'<br />
Email: '.$_POST['emailid'].'<br />
Comments: '.$_POST['comments'].'
';
require "PHPMailer-master/class.phpmailer.php"; //include phpmailer class
// Instantiate Class
$mail = new PHPMailer();
// Set up SMTP
$mail->IsSMTP(); // Sets up a SMTP connection
$mail->SMTPAuth = true; // Connection with the SMTP does require
authorization
$mail->SMTPSecure = "ssl"; // Connect using a TLS connection
$mail->Host = "smtp.gmail.com"; //Gmail SMTP server address
$mail->Port = 465; //Gmail SMTP port
$mail->Encoding = '7bit';
// Authentication
$mail->Username = "xxx@xxx.xx"; // Your full Gmail address
$mail->Password = "xxxxx"; // Your Gmail password
// Compose
$mail->SetFrom($_POST['emailid'], $_POST['fullname']);
$mail->AddReplyTo($_POST['emailid'], $_POST['fullname']);
$mail->Subject = "AL Service Contact Form"; // Subject (which isn't required)
$mail->MsgHTML($message);
// Send To
$mail->AddAddress("post@alservice.no", "AL Service"); // Where to send it - Recipient
$result = $mail->Send(); // Send!
$message = $result ? '<div class="ctrdiv fntsucc"><strong>Meldingen ble sendt! Vi kontakter deg snart.</strong></div><br>' : '<div class="ctrdiv fnterr"><strong>Meldingen ble ikke sendt! Vennligst prøv en gang til.</strong></div><br>';
unset($mail);
}
?>
<?php if(!empty($message)) echo $message; ?>
