Contact Form: Email Not Sent

Question

My contact form does not send an email when the user inputs their contact details and presses the submit button. What am I doing wrong?

HTML:

    <div class="row">
    <form action="mail.php" accept-charset="utf-8" method="post">
    <div class="form-group contacts-form-result">
    <div class="col-xs-12">
    <strong></strong>    
    </div>
    </div>
    <div class="form-group clearfix">
    <div class="col-xs-12 col-md-6">
    <input type="text" placeholder="Your name *" name="name" class="form-control" required>
    </div>
    </div>
    <div class="form-group clearfix">
    <div class="col-xs-12 col-md-6">
    <input type="email" placeholder="Your e-mail address *" name="email" class="form-control" required>
    </div>
    </div>
    <div class="form-group clearfix">
    <div class="col-xs-12">
    <textarea placeholder="Your message *" rows="7" name="message" class="form-control" required></textarea>
    </div>
    </div>
    <div class="form-group clearfix">
    <div class="col-xs-12">
    <button type="submit" class="btn btn-2">Send Enquiry</button>
    </div>
    </div>
    </form>

PHP:

<?php

if (isset($_POST['submit'])){
  $subject = $_POST['subject'];
  $name = $_POST['name'];
  $mailFrom = $_POST['email'];
  $message = $_POST['message'];

  $mailTo = "myemail@email.com";
  $headers = "Enquiry from: ".$mailFrom;
  $txt = "Name: ".$name."\n"."Message: ".$message;

mail($mailTo, $subject, $txt, $headers);

 header("Location: success.html?mailsent");

}?>

How can I fix this, so that on button press, an email is sent? Thank you.

Answer 1

You're checking for a form element named submit :

if (isset($_POST['submit'])){

But you don't have one named submit . Just the type submit . Give it a name:

<button type="submit" name="submit" class="btn btn-2">Send Enquiry</button>

In the key/value pairs sent to the server when posting a form, the element's name attribute is the key. Without a name, it's not sent to the server.
