Re: [PHP] previous page
Larry, Thanks all makes sense, but, if I add this: ?php echo($_SERVER['HTTP_REFERRER']); ? I don't get anything back when the page is called? Cab Larry E . Ullman [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] I have a .php page I don't want anyone being able to just open it unless they've been through a previous page that is a disclaimer http referrer etc come to mind but not exactly sure how to implement it in PHP. Yes, you could check the value of $_SERVER['HTTP_REFERRER'] but that's not perfect. Instead, you could have the previous page contain a form with a special hidden input. The form is submitted to the protected page, where you check for that hidden input's value. If that protected page doesn't receive $_POST data containing whatever meaningful data, redirect them accordingly.

Re: [PHP] previous page
Then you could set a hidden form variable INPUT TYPE=hidden NAME=xxx VALUE=etc or set a sesssion variable on the previous page.

Re: [PHP] previous page
Was ready after searching www.google.com and yes your right about the incorrect spelling of the variable. I also found that some firewalls block the information. So, I now have to go back to the drawing board and build the form. Easy if it was as simple as a form and a submit button but this is a complex spliced image. Larry E .

Simply have the required page set a variable in the session that the protected page checkes for. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
