I can't make Codeigniter session work

Question

I have written the following code.

class Users extends CI_Controller{
    public function login(){
        $this->load->library('session');
        $users=array(
            'name'=>'john',
            'nickname'=>'walker',
            'human'=>true,
          );
        var_dump($this->session->set_userdata($users));

     }
}

The var_dump is giving me NULL. What am I doing wrong?

Answer 1

You are var_dump'ing the result of a set_userdata() and not the session data. Try this

class Users extends CI_Controller{
    public function login(){
        $this->load->library('session');
        $users=array(
            'name'=>'john',
            'nickname'=>'walker',
            'human'=>true,
          );
        $this->session->set_userdata($users);
        print_r($this->session->all_userdata());

     }
}
