Hi Justin, are you using <?php session_start(); ?> at the top of every page you want to keep the session?
Cheers, Joe :) Justin Deutsch <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Hi All, > > I am running Apache with PHP4 as a module. I have also written a script (template.php) that sets up the default envrionment, like the CSS and navigation etc. The script also reads in a file, as defined by the ?path= of the URL. The file it reads in must have the sections (includes, header and body, as defined by /*** ***/ and /*** end ***/ pairs). The file is the split into these sections and along with the templated bits of the page compile into a single string which is the executed using the eval(). Now this all works fine, but I also want to use sessions. The first session from the index.html file, which is first acessed as a login page, stores the player class fine, but when I go to the next page (player_login.html) I seem to loose the session. > > You might ask why I don't just use an existing templating system, well it's because I think that you should only have to write the template once and not have to touch it again. The templating systems I have come across force you to include a file at the top and bottom of the code you are writing. The one down side to the way I am doing it is that I have had to force the other file into a include, header and body section, but this is a trivial formatting issue. > > Is there something I'm missing?
