Question

So this has been killing me for hours.

I have an ajax method that sets sessiondata when the user logs in. I’m sending a few vars via jQuery, and then outputting a message (could have just as well been “true”/”false”), which I am alerting out when it gets back to $.post.

Problem is this.. I am getting the “false” returned, although things seem to work. My session userdata does seem to be setting correctly. I built a button that alerts it out on the page and it is being set. I log out and confirm that all session data is cleared, and re-login and the session data sets correctly again. But the “false”/”PROBLEM WITH SESSION DATA” message is the one that is coming back to jQuery and being alerted every time.

public function setUserSessionData(){
    $picture    = $this->input->post('picture', TRUE);
    $email      = $this->input->post('email', TRUE);
    $first_name = $this->input->post('first_name', TRUE);
    $id         = $this->input->post('id', TRUE);

    ChromePhp::log($picture.$email.$first_name.$id);  // all values good

    $newData = array(
        'loggedInStatus' => 'TRUE',
        'picture'        => $picture,
        'first_name'     => $first_name,
        'id'             => $id,
        'email'          => $email
    );

            // userdata is setting correctly
    if($this->session->set_userdata($newData))
    {
        echo("Session data set"); 
    }
    else
    {
        echo("PROBLEM WITH SESSION DATA"); // this is the message that is outputting
    }
}

Can anyone explain what is going on?

set_userdata() always returns NULL.

I don’t know where you go the idea that set_userdata() should return anything. The documentation does not mention a return value and the code itself is documented as @return void and does not contain a return statement.
