how to put dynamic info in an array?

welp, the header() won't work either...wtf.

this is working, where mains is a controller and performance is a function

Code:

$newdata = array(
                   'page'  => 'mains/performance',
               );
        $this->session->set_userdata($newdata);

however this isn't, event is a controller and $eventid is holding a number because im echoing it out onto the page

Code:

$page = "event/index/".$eventid;
        $newdata = array(
                   'page'  => $page,
               );
        $this->session->set_userdata($newdata);
