Lost session

Don't know if am the only one who witnessed this, the session is lost when a redirection occurs.

Have the session active int the page where you are redirected?
Does any Exception appear?

You're not likely to fix the problem without showing us your session config, and how you are using session.

well the session is initiated in a core controller

function __construct(...$params)
{
parent::__construct(...$params);

Asset::_init();

// Ensure session is running
session()->start();
}




and the session settings



public $sessionDriver = 'CodeIgniter\Session\Handlers\FileHandler';
public $sessionCookieName = 'icvent_session';
public $sessionExpiration = 7200;
public $sessionSavePath = '../../Tarena/writable/temp';
public $sessionMatchIP = false;
//public $sessionTimeToUpdate = 0;
public $sessionTimeToUpdate = 300;
public $sessionRegenerateDestroy = false;

note, when i downgrade to php 5.6, it works well

This is how I start the sessions in a BaseController

What did you Try? What did you Get? What did you Expect?

Tried this, still same thing, once the page redirects, the session is get destroyed

Your sessSavePath doe's not look right to me, I do it like below.

PHP Code:

// change this to below
public $sessionSavePath = '../../Tarena/writable/temp';

// change to this
public $sessionSavePath = WRITEPATH.'temp/'; 


See if that makes a difference.

maybe am not asking the right question, after the session is set, below is what its expected to be when it redirects.

PHP Code:

array(2) { ["__ci_last_regenerate"]=> int(1524320738) ["ticket_order_1448937565"]=> array(14) { ["validation_rules"]=> array(3) { ["ticket_holder_first_name06"]=> string(8) "required" ["ticket_holder_last_name06"]=> string(8) "required" ["ticket_holder_email06"]=> string(20) "required|valid_email" } ["validation_messages"]=> array(3) { ["ticket_holder_first_name06"]=> array(1) { ["required"]=> string(40) "Ticket holder 1's first name is required" } ["ticket_holder_last_name06"]=> array(1) { ["required"]=> string(39) "Ticket holder 1's last name is required" } ["ticket_holder_email06"]=> array(2) { ["required"]=> string(35) "Ticket holder 1's email is required" ["valid_email"]=> string(37) "Ticket holder 1's email must be valid" } } ["event_id"]=> string(1) "7" ["tickets"]=> array(1) { [0]=> array(6) { ["ticket"]=> object(App\Icon\Entities\Tickets\Ticket)#164 (28) { ["ticket_id":protected]=> string(1) "6" ["ticket_event":protected]=> string(1) "7" ["ticket_title":protected]=> string(7) "Another" ["ticket_description":protected]=> string(0) "" ["event_venue_name":protected]=> NULL ["ticket_user":protected]=> string(1) "1" ["event_is_live":protected]=> NULL ["event_venue_name_full":protected]=> NULL ["ticket_quantity_available":protected]=> string(2) "20" ["ticket_max_per_person":protected]=> string(2) "30" ["ticket_start_sale_date":protected]=> string(19) "2018-02-28 17:00:00" ["ticket_end_sale_date":protected]=> NULL ["ticket_created_at":protected]=> string(19) "2018-03-09 15:54:08" ["ticket_updated_at":protected]=> string(19) "2018-04-19 21:13:50" ["ticket_deleted":protected]=> string(1) "0" ["ticket_is_hidden":protected]=> string(1) "0" ["ticket_price":protected]=> string(6) "400.00" ["ticket_is_paused":protected]=> string(1) "0" ["ticket_sort_order":protected]=> string(1) "2" ["ticket_organiser_fees_volume":protected]=> string(4) "0.00" ["ticket_quantity_sold":protected]=> string(1) "0" ["ticket_sales_volume":protected]=> string(4) "0.00" ["ticket_status":protected]=> NULL ["_options":protected]=> array(3) { ["datamap"]=> array(0) { } ["dates"]=> array(4) { [0]=> string(17) "ticket_created_at" [1]=> string(17) "ticket_updated_at" [2]=> string(22) "ticket_start_sale_date" [3]=> string(20) "ticket_end_sale_date" } ["casts"]=> array(0) { } } ["relatives":protected]=> array(0) { } ["ticket_edited_by"]=> NULL ["ticket_min_per_person"]=> string(1) "1" ["ticket_public_id"]=> NULL } ["qty"]=> int(1) ["price"]=> float(400) ["booking_fee"]=> float(0) ["organiser_booking_fee"]=> float(0) ["full_price"]=> float(400) } } ["total_ticket_quantity"]=> int(1) ["order_started"]=> int(1524320738) ["expires"]=> object(Carbon\Carbon)#150 (3) { ["date"]=> string(26) "2018-04-21 15:35:38.759239" ["timezone_type"]=> int(3) ["timezone"]=> string(12) "Africa/Lagos" } ["reserved_tickets_id"]=> int(13) ["order_total"]=> float(400) ["booking_fee"]=> float(0) ["organiser_booking_fee"]=> float(0) ["total_booking_fee"]=> float(0) ["order_requires_payment"]=> bool(true) ["event_owner"]=> string(1) "1" } } 


but after the redirect, here is what is left

PHP Code:

array(1) { ["__ci_last_regenerate"]=> int(1524320922) } 


note, the redirect is done with ajax.

below is the code from the setting of the session downward.

PHP Code:

/*
        * The 'ticket_order_{event_id}' session stores everything we need to complete the transaction.
        */
          session()->set('ticket_order_' . $event_Id, [
          'validation_rules'        => $validation_rules,
          'validation_messages'     => $validation_messages,
          'event_id'                => $event->event_id,
          'tickets'                 => $tickets,
          'total_ticket_quantity'   => $total_ticket_quantity,
          'order_started'           => time(),
          'expires'                 => $order_expires_time,
          'order_total'             => $order_total,
          'order_requires_payment'  => (ceil($order_total) == 0) ? false : true,
          'event_owner'              => $event->user->user_id,
          ]);
          

          /*
        * If we're this far assume everything is OK and redirect them
        * to the the checkout page.
       */
       //var_dump($_SESSION);
        //die;
          if ($this->request->isAJAX()) 
          {
          return json_encode([
             'status'      => 'success',
             'redirectUrl' => route_to('showEventCheckout',$event_Id,$event->event_slug),
          ]);
          }else{
              /*
            * Maybe display something prettier than this?
            */
              exit('Please enable Javascript in your browser.');
          } 


I think you are asking the right question. Something in the session config is not correct resulting in "lost" sessions.

I'm not truely up to speed with CI 4 but I think your $sessionDriver value looks wrong. Try this.

PHP Code:

public $sessionDriver = 'files'; 


And as @InsiteFX suggests, make sure the file path is correct. Of particular importance is that only absolute paths are supported for $sessionSavePath.
