Codeigniter 3.1.7 is losing session when this is called through a method

Question

I have a method which retrieve a session created before in a method. This method is called from AJAX and is something like:

public function Confirmar() {
   print_r($this->session->userdata);
}

The session was created before from one method in the same controller which is:

public function Token($token) {
    $params = array('tokenvalido' => true, 'token_de_cambio' => $token, 'user_mail' => $TokenValido->user_mail);
    $this->session->set_userdata($params);
}

When i make a var_dump($this->session->userdata) in the Token method, I'm getting this response:

Array ( [__ci_last_regenerate] => 1522819707 [tokenvalido] => 1 [token_de_cambio] => 5ac44d3e7dc5cd0d11e2edbdb34ae13f05d60c3b64978 [user_mail] => babasonicofernando@gmail.com )

But when I called the Confirmar() method (which exists in the same controller where I create the session) this is displaying an empty array.

What I'm doing wrong?

Answer 1

userdata is method so you have to add () at end in . so change your code as below

public function Confirmar() {
   print_r($this->session->userdata());
}

Answer 2

您可以尝试：

print_r($this->session->userdata('token_de_cambio'))

Answer 3

这段时间过后，我注意到在php.ini中启用了session.auto_start指令，此问题已解决。
