Wondering if anyone know how to automatically send the user an email after he/she fills out a form. I have the form emailed to me after it gets submitted, but I can't figure out how to capture the user's email from the form field and have it send it to them automatically???

Here is some code that I use to send the mail:

  //mail the message before redirecting
if($_POST['dosend'] == "yes"){

// The message
$headers = "From: [email protected]";

$message = "NEW Message :: ".$_POST['event_name']." \n Email: ".$_POST['email']." \n Click link to http://www.domain.com/admin/ Approve this Event!";

// Send
mail('[email protected]', 'New :: Calendar Message', $message, $headers);
}
  //end mail
