php - CodeIgniter How to access session variables in twig templates -

somebody can me please. i'm new in codeigniter , twig. have declared in controller following:

$datasession = array( 'nick' => $sess_nick, 'login_ok' => true );  $this->session->set_userdata($datasession);  redirect('app'); //app controller render template view. 

then, question is: how can variables twig template? tried using:

{{ session.userdata.nick }} 

but shows empty string.

thanks advance.

to add session variable on twig template, have add following line in twig library or controller.

$datasession = array(     'nick' => $sess_nick,     'login_ok' => true ); $this->session->set_userdata($datasession); $this->_twig->addglobal("session", $this->ci->session); 

then on twig template, can print session this

{{ session.userdata.nick }} 

since in codeigniter, session stored user in userdata array. otherwise, can call session variable , name

{{ session.nick }}
