Ballotpedia test

Here is a rough idea:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <title>Code Test for Ballotpedia</title>
  </head>
  <body>
  	<h1>Code Test for Ballotpedia</h1>
  	<form id="contact_form" action="#" method="POST" enctype="multipart/form-data">
	<div class="row">
		<label for="name">Your name:</label><br />
		<input id="name" class="input" name="name" type="text" value="" size="30" /><br />
	</div>
	<div class="row">
		<label for="email">Your email:</label><br />
		<input id="email" class="input" name="email" type="text" value="" size="30" /><br />
	</div>
	<div class="row">
		<label for="message">Your message:</label><br />
		<textarea id="message" class="input" name="message" rows="7" cols="30"></textarea><br />
	</div>
	<input id="submit_button" type="submit" value="Send email" />
</form>

<script>

// form processing

	$(document).ready(function() {

    $('form').submit(function(event) {

        var formData = {
            'name'              : $('input[name=name]').val(),
            'email'             : $('input[name=email]').val(),
            'message'    : $('input[name=message]').val()
        };

        $.ajax({
            type        : 'POST',
            url         : 'process.php',
            data        : formData,
            dataType    : 'json',
                        encode          : true
        })
            .done(function(data) {
            });

        event.preventDefault();
    });

});
</script>
  </body>
</html>

This would then be that process.php referenced above:

<?php

$form_errors         = array();
$response_data           = array();


    if (empty($_POST['name']))
        $form_errors['name'] = 'Name is required.';

    if (empty($_POST['email']))
        $form_errors['email'] = 'Email is required.';

    if (empty($_POST['message']))
        $form_errors['message'] = 'Message is required.';

    if ( ! empty($errors)) {

        // if there are items in our errors array, return those errors
        $data['success'] = false;
        $data['errors']  = $errors;
    } else {

        // send email
        $to = "ballotpedia@example.com";
        $email_subject = "Contact form submission: " . $_POST['name'];
        $email_body = "You have received a new message. ".
        " Here are the details:\n Name: $name \n ".
        "Email: $email_address\n Message \n $message";
        $headers = "From: ballotpedia@example.com\n";
        $headers .= "Reply-To: ballotpedia@example.com";
        mail($to,$email_subject,$email_body,$headers);

        $data['success'] = true;
        $data['message'] = 'Thanks for your message!';
    }

    // return response back to page
    echo json_encode($data);

    ?>
