在登录操作结束时访问新的session_id

Question

Consider the following code:

function authenticate(){
    $this->session->set_userdata('logged_in', true);
}

How do I return this users session_id from the authenticate function? It's not available from the session class until the page is refreshed.

Answer 1

Have you tried this

    $this->load->library('session');
    echo $this->session->userdata('session_id');


function authenticate(){
    $this->session->set_userdata('logged_in', true);
return $this->session->userdata('session_id');
}
