Setting a SESSION variable in txp

I have an include with my own php code which, once certain criteria are met, sets a session variable (an array). When I navigate away from the page to another page on the same site I don’t seem to be able to access the session variable.

Does txp unset custom session variables?

Nope. Not that I’m aware of. As long as your code runs on every page and has session_start() somewhere near the top of the page then you’ll be good to go.

But bear in mind that some plugins use sessions (yab_shop and MLP spring to mind) so if you have either of those installed they might be hijacking your custom session.

OK that works thanks.

I’d made the assumption that txp calls session_start() so didn’t think I would have to.

Nope, Textpattern itself doesn’t use sessions. In case some plugin does, you can make sure to not to call session_start() twice by checking if $_SESSION is set. I.e.

if(!isset($_SESSION))
	session_start();
