Contact form won't submit on button press

Question

Struggling to get my contact form to send. I've pasted the code below

When i fill in the form and push send, nothing happens. I've tried using a button as opposed to an input submit but that still does nothing. I've had forms like this before work fine but now I just can't get this to send. Any clues?

<form id="contact-form" method="post" action="process.php">
  <div class="row">
    <div class="col-md-6 col-lg-6 col-sm-12 col-xs-12">
      <div class="form-group" id="name-field">
        <div class="form-input">
          <input type="text" class="form-control" id="form-name" name="form-name" placeholder="Full Name">

Answer 1

The $message variable is used twice... once to receive data from the form, and then you overwrite it? You may want to use a different variable for that. I changed to $msg.

Also, you have a lot of needless php tags. Maybe try something a little cleaner like this to start:

<?php
$to = "info@blank.co.uk";
$subject = "Contact Page from ";
$headers  = "From: A T L <noreply@blank.co.uk>\r\n";
$headers .= "Reply-To: noreply@blank.co.uk\r\n";
$headers .= "Return-Path: noreply@blank.co.uk\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset: utf8\r\n";
$name = filter_input(INPUT_POST, 'form-name');
$email = filter_input(INPUT_POST, 'form-email');   
$address = filter_input(INPUT_POST, 'form-address');
$telephone = filter_input(INPUT_POST, 'form-phone');
$theirSub = filter_input(INPUT_POST, 'form-subject');
$msg = filter_input(INPUT_POST, 'form-message');

$message = 
"<span style='font-weight: bold;'>Name: </span>"."<br />".$name."<br />"."<br />".
"<span style='font-weight: bold;'>Email: </span>"."<br />".$email."<br />"."<br />".
"<span style='font-weight: bold;'>Address: </span>"."<br />".$address."<br />"."<br />".
"<span style='font-weight: bold;'>Telephone: </span>"."<br />".$telephone."<br />"."<br />".
"<span style='font-weight: bold;'>Email: </span>"."<br />".$email."<br />"."<br />".
"<span style='font-weight: bold;'>Subject: </span>"."<br />".$theirSub."<br />"."<br />".
"<span style='font-weight: bold;'>Message: </span>"."<br />".$msg."<br />"."<br />";

mail($to, $subject,"We have received a message via the online form at www.blank.co.uk<br /><br />" . $message, $headers);
echo "Your message was successfully sent. Please <a href='contact.php'>click here</a> to return to the site.";
?>
