Re: Cookies detect and $_SESSION

Hi John, This is done on the first page: <?php session_start(); ob_start(); ?> /* html . . head stuff . . . . <?php if ($_SESSION['cookie'] == "") { print("<h2>Please 'Enable Cookies' to use this site</h2>"); $_SESSION['cookie'] = "1"; session_write_close(); } if($_SESSION['cookie'] != "") {} ?> This code sort of works. When I first load the page with cookies enabled, I get the 'Enable Cookies please' message. However, if I reload or move to another page, and return, it disappears because of the '$_SESSION['cookie'] = "1" '. With cookies disabled, it works as it should. Perhaps this is the best it will get without further fancy footwork, but it would be nice not to have the 'error' message display for those who do have cookies enabled. Any suggestions? Thnaks again for your help, Regards, Andre . . . On Monday 05 August 2002 08:36 pm, 1LT John W. Holmes wrote: > > Hi John, > > > > That makes sense. I guess it's brain-bloat.
