Question

我创建了一个PHP / HTML表单，由于某些原因，它不会将信息发送到我的电子邮件，这里是我的代码

PHP

<?php
$email = $_POST['email'];
$dropdown = $_POST['dropdown'];
$game = $_POST['game'];
$describe = $_POST['describe'];
$form = "From $email";
$to = 'godlikegames@outlook.dk';
$subject = 'Game report';

$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html\r\n";
$headers = 'From: from@example.com' . "\r\n" .
'Reply-To: reply@example.com' . "\r\n" .
'X-Mailer: PHP/' . phpversion();

$mailheader = "From $email\r\n";
$body = "E-Mail: $email\n Message:\n $describe";

if ($_POST['submit']) {
    if ($email != '') {
           if (mail('godlikegames@outlook.dk', $subject, $describe, $from))     {
            header("location: http://www.godlike-games.com/Thankyou.html");
        } else {
        echo "<script type=\"text/javascript\">window.alert('Something went     wrong, Reloading. . .');
        window.location.href = '/ReportABug.html';</script>";
        exit;
        }
    } else {
      echo "<script type=\"text/javascript\">window.alert('You forgot to fill     out something, Reloading. . .');
      window.location.href = '/ReportABug.html';</script>";
      exit;
    }
}
?>
