PHP form sends but "No Sender" - php

Question

I am able to receive email with all the information except for the email address that is entered in the form, and when I receive the email, I get "No Sender" instead of the person's name or email.
This is my HTML:
<!-- Contact Form -->
<div class="col-xs-12 col-sm-8 col-md-8">
<div id="contant-form-bx" class="contant-form-bx">
<div class="contact-loader"></div>
<form action="mail.php" id="contact-form" class="contact-form" name="cform" method="post">
<div class="row">
<div class="col-md-6">
<label for="name" id="name_label">Name</label>
<span class="name-missing">Please enter your name!</span>
<input id="name" type="text" value="" name="name" size="30">
</div>
<div class="col-md-6 columns">
<label for="e-mail" id="email_label">Email</label>
<span class="email-missing">Please enter a valid e-mail!</span>
<input id="e-mail" type="text" value="" name="email" size="30">
</div>
<div class="col-md-12">
<label for="message" id="phone_label">Message</label>
<span class="message-missing">Say something!</span>
<textarea id="message" name="message" rows="7" cols="40"></textarea>
</div>
<div class="col-md-12 text-center">
<input type="submit" name="submit" class="button" id="submit_btn" value="Send Message">
</div>
</div>
</form>
</div>
</div>
This is my PHP:
<?php
// declare our variables
$name = $_POST['name'];
$email = $_POST['e-mail'];
$message = nl2br($_POST['message']);
// set a title for the message
$subject = "From $name via WEB";
$body = "From $name, \n\n$message";
$headers = 'From: '.$email.'' . "\r\n" .
'Reply-To: '.$email.'' . "\r\n" .
'Content-type: text/html; charset=utf-8' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
// put your email address here
mail("info#wziel.com", $subject, $body, $headers);
?>
<!--Display a Thank you message in the callback -->
<div class="mail_response">
<h4>Thank you <?php echo $name ?>!</h4>
<p>I'll be in touch real soon!</p>
</div>

Answer 1

According to your form this:
$email = $_POST['e-mail'];
Should be this:
$email = $_POST['email'];
You have e-mail as the id not the name.
The php looks at name and not id

Answer 2

You're using $_POST['e-mail']. e-mail is the ID of the <input> tag. You should be using $_POST['email'] because name="email".
