Response to: Register Globals on
Thanks for the reply.. That means that if and only if the data is being passed vai GET method, the question of security in regard to register globals on, comes into play.. what if the method used is POST? Thanks again for the reply Cheers

  Using POST instead of GET does not secure any script at all. Imagine creating your custom form on your local machine and directing the action to http://www.somwhere.net/someaction.php

  My method for securing where POST data comes from is thus:
  
  $referer = $_SERVER['HTTP_REFERER'];
  if ($referer != "http://www.domain.com/form.html") {
  echo "nice try!";
  } else {
  process_form();
  }
  
  Any downside to that (other than having to change the URL upon upload)?

  That's certainly not a certain test though. I could create a program to do the post and it would set HTTP_REFERER to what you are looking for.

  The value of $_SERVER['HTTP_REFERER'] comes from the Referer header in the HTTP request constructed by the client software. If the client is a regular browser, the referer will probably be set correctly, but the referer request header could be forged by a malicious user.
