codeigniter 4 session or cache issue
#1

(This post was last modified: 01-14-2021, 07:01 AM by adil.)

[font=Arial,]I created a website using CI4 and it was working fine. On Wampserver its working fine. Now if change anything and update the server it shows the old data and session not working properly sometime. i think browser is caching the webpage. Is there any way to disable in CI4? is it cache issue or session? old data means if i change a css or a section of html it wont reflect the change. and old html shows.same for dynamic data.Cannot login,session not holding login details. for session iam using database. Everything works fine on local server.issue only on live server. iam using plesk hosting. Anyone have this issue? When tried on a new pc it works fine. And if any update made and try again issue comes initiated session in base controller.
[/font]

Code:
$this->session = \Config\Services::session();

[font=Arial,]i use this in the controller for cache control

[/font]

Code:
header('Access-Control-Allow-Methods: POST, GET, PUT, DELETE, OPTIONS');
//header("Cache-Control: public, max-age=60, s-maxage=60");
header("Cache-Control: no-cache, no-store, must-revalidate"); // HTTP 1.1.
header("Pragma: no-cache"); // HTTP 1.0.
header("Expires: 0"); // Proxies.

[font=Arial,]App configuration for session:

[/font]

Code:
    public $sessionCookieName  = 'ci_session';
    public $sessionSavePath = 'ci_sessions';
    public $sessionExpiration        = 7200;
    //public $sessionSavePath          = WRITEPATH . 'session';
    public $sessionMatchIP           = false;
    public $sessionTimeToUpdate      = 300;
    public $sessionRegenerateDestroy = false;

[font=Arial,]Tried Empty/Cache and hard reload. no caching is enable in the code

Edit: i checked the browser as mentioned in comment and its caching
[/font]

Code:
cache-control: max-age=315360000

content-length: 9333
content-security-policy: upgrade-insecure-requests;

[font=Arial,]i dont know how this is caching.

the base controller
[/font]

Code:
<?php

* and performing functions that are needed by all your controllers.
* Extend this class in any new controllers:
*     class Home extends BaseController

* @package CodeIgniter

use Config\Services;

class BaseController extends Controller
{

    /**
     * An array of helpers to be loaded automatically upon
     * class instantiation. These helpers will be available
     * to all other controllers that extend BaseController.
     *

     */
    protected $helpers = ['form', 'url','master'];
        protected $session;
    /**

     */
    public function initController(\CodeIgniter\HTTP\RequestInterface $request, \CodeIgniter\HTTP\ResponseInterface $response, \Psr\Log\LoggerInterface $logger)
    {
        // Do Not Edit This Line
        parent::initController($request, $response, $logger);

        //--------------------------------------------------------------------
        // Preload any models, libraries, etc, here.
        //--------------------------------------------------------------------
        // E.g.:
         $this->session = \Config\Services::session();

                     $this->pager = \Config\Services::pager();

}

[font=Arial,]this is the login function

1) If your using Chrome bring up the developer tools F12
2) Right click the circle in the top left toolbar
3) Click on Empty/Cache and hard reload.

Why are you so convinced it’s a browser issue? What do you change on the server that is supposedly keep in the browser cache on is not refreshed? If it’s JS or CSS, it’s standard browser behavior and has nothing to do with CI. It it’s something else, it’s probably a bug in your code.

got almost working fine now.
added header() to controller and added 
Code:
class BaseController extends Controller
{
    /**
     * An array of helpers to be loaded automatically upon
     * class instantiation. These helpers will be available
     * to all other controllers that extend BaseController.
     *
     * @var array
     */
    protected $helpers = ['form', 'url', 'master'];
    protected $session;
    /**
     * Constructor.
     */
    public function initController(\CodeIgniter\HTTP\RequestInterface $request, \CodeIgniter\HTTP\ResponseInterface $response, \Psr\Log\LoggerInterface $logger)
    {
         
        // Do Not Edit This Line
        parent::initController($request, $response, $logger);
        //--------------------------------------------------------------------
        // Preload any models, libraries, etc, here.
        //--------------------------------------------------------------------
        // E.g.:
        $response->noCache();
        //print_r($response->getHeaders());exit;
        $this->session = \Config\Services::session();
        date_default_timezone_set('Asia/Dubai');
        $this->pager = \Config\Services::pager();
    }

to base controller.
still some caching reamining
when is try to get latest messages from user with  getMsgsByCustomer in below function
Code:
public function viewProfile($cID)
    {
      
        $data['states'] = states();
        $cmSerModel = new customerServiceModel;
        if (session('customerData')) {
            $data['customerDetails'] = $cmsrDetails = session('customerData');
            $data['msgs'] = $cmSerModel->getMsgsByCustomer($cmsrDetails['customerID']);
            $page = 'profilePage';
            if (!is_file(APPPATH . '/Views/home/' . $page . '.php')) {
                throw new \CodeIgniter\Exceptions\PageNotFoundException($page);
            }
            $data['title'] = "Customer Profile";
            echo view('home/profilePage', $data);
        } else {
            return redirect()->to('/');
        }
    }
in model
Code:
    public function getMsgsByCustomer($id = '')
    {
   
        $this->asArray();
        $this->where('customerID',$id);
        $query = $this->findAll();
       
      
        return $query;
    }

it still not showing updated messages.

Because it doe's not know where to find this 

PHP Code:
$cmsrDetails['customerID'

It's not in that method so where is it?

it is from session after login in.
Code:
$data['customerDetails'] = $cmsrDetails = session('customerData');
session have customer details including "customerID".
only latest messages are not showing.older database entries are showing in webpage.
if i delete it any old entries from db it still show on webpage.
