Question

I’m trying to check if its set in my codeigniter application like:

elseif(!isset($this->session->userdata('session_id'))){ ## SESSION data is NOT set
            // load a generic 'issue' occurred view.
        }

but I keep getting this error, is !isset not valid in Codeigniter? How do I go about easily checking this?

Thanks

You must use the code like below:

$id = $this->session->userdata('session_id');
// your other code
elseif(!isset($id)){ 
        // load a generic 'issue' occurred view.
}
