title: PHP form sending blank emails
body: <p>I don't have a lot of experience with PHP - I used a form generator to create this form.  The problem is that the form is sending hundreds of blank emails.  Can anyone please help me fix it?  Here's the PHP code:</p>
  
  <pre><code> &lt;?php
  
  $where_form_is="http://".$_SERVER['SERVER_NAME'].strrev(strstr(strrev($_SERVER['PHP_SELF']),"/"));
  
  mail("blah@blah.com","MESSAGE: website","
  
  Someone has submitted a message from your website!  Huzzah!
  
  --------------------------------------------------------------------------------
  
  CONTACT INFO:
  " . $_POST['field_1'] . "
  " . $_POST['field_2'] . " 
  
  MESSAGE:
  " . $_POST['field_3'] . " 
  
  --------------------------------------------------------------------------------
  
  Also you're a stud.

  header("Refresh: 0;url=http://www.blah.com/thanks.html");
