Session Can't Be Set and return Null

Question

So here is the code for eppkm.php (the page that I need to be protected) The session is settled simply by submit a form that have token value.

<?php session_start();
include_once"pengaturan/crud.php";

if (isset($_POST['token'])) 
{
        $token = $_POST['token'];
        $_SESSION['user'] = true;
        $konek->login($token);
}
else
{
        $_SESSION['user'] = true;
        $konek->login($token);
}

?>

And here is the pengaturan/crud.php file, login function:

public function login($token)
    {

      if (isset($token)) 
      {  
        $query = "SELECT * FROM master_users WHERE remember_token = '". $token ."'" ;
        $hasil = pg_query(Parent::get_dbcon(),$query);

        if (pg_num_rows($hasil) != 1)
        {
          echo "nothing";
          //header("Location: http://192.168.0.190/eppkm_ex/public/master/login");       
        }

      }

      else{
        if(!isset($_SESSION['user'])){
        session_destroy();
        header("Location: http://192.168.0.190/eppkm_ex/public/master/login");
          }
      }

    }

When I tried to echo the session, it says Undefined index: user and also tried var_dump the session, the result comes to null which mean the session isn't settled.

Can you help me fix the session? And point me where am I doing wrong :(

I've encounter similar issue in the past 7-8 years ago from what I remember the issue is not related to $_SESSION but the value Boolean

I would suggest converting em to string/integer or alternatively per explanation below

here's explaination:

A boolean TRUE value is converted to the string "1". Boolean FALSE is converted to "" (the empty string). This allows conversion back and forth between boolean and string values.

Yes, i change `$_SESSION['user'] = $token`, but nothing happened. The problem is same, session not settled. – Marionette Readram Jul 10 '17 at 03:16
are you trying to redirect page after setting session? if Yes can you try adding session_write_close(); above redirect code like example: session_write_close(); header("Location: /yourpage.php"); – Fernan Vecina Jul 10 '17 at 03:29

Your code is working fine !

Check

Please set error_reporting(E_ALL); and ini_set('display_errors', 1); at top of the file or CHeck.
