I have used a session check type function in another site where if certain session variables aren't registered then it includes a login page. It worked like a charm.

I copied and pasted the code over and changed the names of the session variables and the path to the include file but every time I run the page in the browser the session check function gets ignored totally. I even entered a bad path in the include statement. Still gets ignored.

So I put the funciton in an include file and the include code in the page got ingnored then too.

What is going on?

PS Session check looks like this:

// <?php function session_checker(){ if(!session_is_registered('xtra_first') && !session_is_registered('xtra_password') && // !session_is_registered('xtra_clearance') && !session_is_registered('xtra_ID')) { // include '../../path_to_login_form'; // exit(); // 	} // } // ?>
// <?php session_start(); ?>
// <?php session_checker(); ?>

Have you tried using the superglobals?

Ok Jerry,

I might have put my finger on the problem. I copied the code from a simple text file and apparently it also pasted in some hidden characters (i.e. tabs, returns) Seems like if I retyped the code myself and but in the tabs and returns myself right in source mode it starts to work. Any truth to this assumption.

Could be since tabs and new-lines etc are supposed to be markup elements. This would force the PHP runtime to treat the items as HTML rather than code by un-linking the php enclosure tags themselves.

However, if it was 'simpletext' it wouldn't have those. Could you 'show invisibles' like in BBEDIT?
