I've tried both version 1 and version 2 of this CJ Printer Friendly concept and both fail, apparently because I'm somehow not showing the HTTP_REFERER value that it expects to find.

My environment is Win2K with IIS and PHP 4.3.2.

My PHP script generates a small display of values that the user just created by filling in a form.

Within the display, I've included the <!--start--> and <!--end-->.

When I execute the HREF to the printpage.php, the content between the start/end is NOT passed and the printpage script howls about the absence of HTTP_REFERRER.

PHP is running GLOBALS OFF but sessions are in use.

If you have an idea on what to do to make it work, short of creating static HTML files, please drop me a note.

TIA.

$HTTP_REFERER is a variable that stores the page that a visitor has come from. If cj-design.com has a link to your site, and a visitor clicks on that link, the cj-design page will be stored in the variable. If you type the address to the script into the address bar directly, there will not be a value in $HTTP_REFERER.

Try creating a page with a link to the script instead of typing the address in directly.
