Two things: The undefined notice you are getting is the result of your error_reporting setting in your php.ini... http://www.php.net/manual/en/function.error-reporting.php
What is ultimately causing the error is that not all HTTP requests to your page have a referrer defined, therefore, on the occasions that the client did not specify the referrer, you are getting the undefined notice because it did not exist. You can test this my having a page that echoes out the HTTP_REFERRER variable and also contains a link to itself....I think you will catch on when you see it in action. <?php echo 'Referrer: '.$_SERVER['HTTP_REFERRER']; echo '<br><a href="'. $PHP_SELF .'">Link</a>'; ?> > -----Original Message----- > From: R.S.
