title: In this tutorial, why does it tell us to mess with the $_POST['email']?

  <p>I am really confused about three particular lines of code in this tutorial to create a login page and databse, on the page I have listed above.</p>
  
  <pre><code>if (!get_magic_quotes_gpc()) {
  
          $_POST['email'] = addslashes($_POST['email']);
  
      }
  </code></pre>
  
  <p>Why is she fiddling with the $_POST['email'] value, when it isn't even in an input box?</p>
  
  <p>EDIT:</p>
  
  <p>I still cannot find an input box for email, I have even copied and pasted the entire site. I still can't find one box that says email.</p>
