提交时不会以联系方式调用PHP

Question

在将此标记为重复之前，请实际阅读我要说的内容。这不是电子邮件未被发送的问题，单击提交按钮时实际上并未调用PHP。

代码

<?php 
if(isset($_POST['SubmitButton'])){
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['message'];
    $formcontent="From: $name \n Message: $message";
    $recipient = "reviews@itssimplytech.co.uk";
    $subject = "Simply Tech Contact Form";
    $headers = 'From: '$email"\r\n".
    'Reply-To: '$email"\r\n" .
    'X-Mailer: PHP/' . phpversion();
    mail($recipient, $subject, $formcontent, $headers) or die("Error!");  
    echo "Thank You!";
    ?>
    <a data-scroll href="#contact"></a>
    <?php
}
?>
<form class="contact-form" action="" method="post">
    <input type="text" name="name" placeholder="Name" required>
    <input type="email" name="email" placeholder="Email" required>
    <textarea rows="5" name="message" placeholder="Say Something..." required></textarea>
    <input type="submit" name="SubmitButton" value="Submit">
</form> <!--  /.contact-form  -->

当提交表单时，页面只是刷新并且表单被清除但是我不认为它正在调用PHP，因为没有发送电子邮件并且没有显示任何消息，也没有向下滚动到联系。这条线应该做到这一点。

<a data-scroll href="#contact"></a>
