<!-- To configure the contact form email address, go to mail/contact_me.php and update the email address in the PHP file on line 19. -->

</section>
<-----PHP----->
<?php
if(empty($_POST['name']) ||
empty($_POST['emailz']) ||
empty($_POST['phone']) ||
empty($_POST['message']) ||
!filter_var($_POST['emailz'],FILTER_VALIDATE_EMAIL))
{
echo "No arguments Provided!!";
return false;
}
$name = $_POST['name'];
$email = $_POST['emailz'];
$phone = $_POST['phone'];
$message = $_POST['message'];
$headers = "From: noreply#yourdomain.com\n"; // This is the email address the generated message will be from
$headers .= "Reply-To: $emailz";
$subject = 'New Message - Kieronb- $name';
$body = "You have received a new message from your website contact form.\n\n"."Here are the details:\n\nName: $name\n\nEmail: $emailz\n\nPhone: $phone\n\nMessage:\n$message";
mail("k#gmail.com",$subject,$body,$headers);
return true;
?>
SO, the above is the HTML and the PHP, now the majority of this code has been frankensteined from a bootstrap project, but i thought i would just have a play with the contact form too, but it is going all the way through to the missing arguments catch at the beginning of the PHP.
I cant see why the data is coming through empty- have i missed something painfully obvious?
I am running on a web server, not locally.
Thanks
Edit; thanks everyone, i forgot my method, and names on the form!

Answer 1

Your form fields do not have the name attribute. Without them their values are not submitted with the form.
<input type="email" class="form-control" placeholder="Email Address" id="emailz" required data-validation-required-message="Please enter your email address.">
should be
<input type="email" name="emailz" class="form-control" placeholder="Email Address" id="emailz" required data-validation-required-message="Please enter your email address.">
And your <form> needs to have the method specified as POST or else it defaults to GET:
<form method="post" name="sentMessage" id="contactForm" onsubmit="return validate()" action="contactme.php">
