Check session exit ?

[eluser]dnc[/eluser]
Just Like Oscar Dias said when you unset the session it should return false. If you want to make sure than just like was said in PHP:

Code:

if(!isset($this->session->userdata('uid'))) {

//do whatever you need to do. The session['uid'] is not set

}

By the way your still working with "normal" PHP. Just got an awesome framework to kickstat your work with.
