How to use cookie value globally in cakephp 4 version? - cookies

Question

I want to set cookie value in one function and their value use everywhere in cakephp 4 version.
Currently , i can use cookie value inside the only one function which i have set their value.
I can get cookie value in index() function but i can't get cookie value in viewusers() function.
Code is here :
use App\Controller\AppController;
use Cake\Http\Cookie\Cookie;
use Cake\Http\Cookie\CookieCollection
use DateTime;
class AdminController extends AppController {
function index(){
$cookie = array();
$cookie['admin_username'] = $requestData['username'];
$cookie['admin_password'] = $requestData['password'];
$cookies = new Cookie('AuthAdmin',$cookie, new DateTime('+1 weeks'));
$response = $this->response->withCookie($cookie);
return $this->redirect('admin/viewusers');
}
function viewusers() {
$cookies = new CookieCollection();
$data = $cookies->get('AuthAdmin');
print_r($data);
// cookie value not found in $data variable.
$response = $this->response->getCookie('Auth.Admin');
print_r($response);
// cookie value not found in $response variable.
}
}
I can get cookie value in index() function but i can't get cookie value in viewusers() function.

Try this:
function index(){
$cookie = array();
$cookie['admin_username'] = $requestData['username'];
$cookie['admin_password'] = $requestData['password'];
$cookies = new Cookie('AuthAdmin',$cookie, new DateTime('+1 weeks'));
return $this
// redirect returns a response object, so you can chain the cookie call onto that
->redirect('admin/viewusers')
// Note that this uses $cookies, not $cookie
->withCookie($cookies);
}
But again, I cannot stress strongly enough that sending a cookie with the user's username and password in it is a very bad thing from a security perspective.
