php send email with variables pulled from POST form

[Joe Farage]

I can't figure out why this page doesn't work. It pulls from a html page that is set to POST when the submit button is clicked but I receive an error saying that the page may be configured incorrectly?
What did I do wrong? I think it may have something to do with putting $_POST in the variables but I don't know for sure.

Thank you <?php echo $_POST["name"]; ?> for registering for the Office Equipment Smash event!  
</br>You have registered <?php echo $_POST["quantity"]; ?> people for the <?php echo $_POST["reg"]; ?> event(s).
</br>You will be receiving a confirmation email shortly.  
</br></br>If you don't receive the confirmation within 24 hours, please resubmit </br>your registration or send an email to [e-mail].
<?php
$to = "[e-mail]";
$subject = "NEW REGISTRATION for Office Equipment Smash!";
$message = "$_POST['name'] Has registered $_POST['quantity'] people for the $_POST['reg'] event(s).  You will be receiving a confirmation email shortly.";
$from = "$_POST['email']";
$headers = "From: . $from";
mail($to,$subject,$message,$headers);
echo "Mail Sent.";
?>
</body>
</html>

at number line:
why do you write this way?

$from = "$_POST['email']";
 

simply write

$from = $_POST['email'];
 

And i am not sure which quote works in which one, i dont use it.

i always concat string
your code:

$message = "$_POST['name'] Has registered $_POST['quantity'] people for the $_POST['reg'] event(s).  You will be receiving a confirmation email shortly.";

my code would be

$message = $_POST['name']." Has registered ".$_POST['quantity']." people for the ".$_POST['reg']." event(s).  You will be receiving a confirmation email shortly.";
 

and finally make sure all of your post variable exists.

just use print_r function what variable and data you are using.
