Hello I have setup a contact form using the below link: https://mdbootstrap.com/components/bootstrap-contact-form/     I would like to add the checkbox validation option. I am quite new to this and am not sure whether to but the PHP code presented in the tutorial. I have added the HTML:

<div class="form-check">
    <input type="checkbox" class="form-check-input" name="updates" id="updates" value="1">
    <label for="updates" class="form-check-label">Notify me about new updates</label>
</div>

and the JS line:

formData = {
    'name'     : $('input[name=name]').val(),
    'email'    : $('input[name=email]').val(),
    'subject'  : $('input[name=subject]').val(),
    'message'  : $('textarea[name=message]').val(),
    'updates'  : $('input:checkbox[name=updates]').is(':checked')
};

but the PHP code I am unsure about, I also want it to display an error message if the checkbox isn't checked but it doesn't look like this will do it by default ?

I wasnt sure if you could combine the:

if ($message === ''){
 print json_encode(array('message' => 'Message cannot be empty', 'code' => 0));
 exit();
}

with the code provided :


if(isset( $_POST['updates']))
 $updates = $_POST['updates'];


my first attempt was this below, adding the $updates = $_POST['updates']; to the top of the php and then adding the
if(isset( $_POST['updates']))
 $updates = $_POST['updates']; 

after the message if statement.

<?php $name = $_POST['name']; $surname = $_POST['surname']; $email = $_POST['email']; $message = $_POST['message']; $subject = $_POST['subject']; $updates = $_POST['updates']; header('Content-Type: application/json'); if ($name === ''){ print json_encode(array('message' => 'Name cannot be empty', 'code' => 0)); exit(); } if ($surname === ''){ print json_encode(array('message' => 'Surname cannot be empty', 'code' => 0)); exit(); } if ($email === ''){ print json_encode(array('message' => 'Email cannot be empty', 'code' => 0)); exit(); } else { if (!filter_var($email, FILTER_VALIDATE_EMAIL)){ print json_encode(array('message' => 'Email format invalid.', 'code' => 0)); exit(); } } if ($subject === ''){ print json_encode(array('message' => 'Subject cannot be empty', 'code' => 0)); exit(); } if ($message === ''){ print json_encode(array('message' => 'Message cannot be empty', 'code' => 0)); exit(); } if(isset( $_POST['updates'])) $updates = $_POST['updates']; $content="From: $name nSurname: $surname nEmail: $email nMessage: $message"; $recipient = "tommyhutcheson@gmail.com"; $mailheader = "From: $email rn"; mail($recipient, $subject, $content, $mailheader) or die("Error!"); print json_encode(array('message' => 'Email successfully sent!', 'code' => 1)); exit(); ?>

Thank you 

Tommy
