Question

Assume user adding some products (via Add button), and then click on the checkout button.

If user have not logged in, it will redirect to a /login page.

After logged, how to redirect back to the checkout page?

by default, when user have logged in – it will redirect to a /account page.

I have created my own login authentication class.

checkout page, sample code:

if ($this->memberID) {
  //show checkout page
} else {
   header("location: /login");
}

Note: I use jquery ajax (to php) to check login detail

Answer 1

You can add before

header("location: /login");

some data to the session like:

$_SESSION['redirectAfterLogin'] = '/account';

And in Login controller after successed login, check if $_SESSION['redirectAfterLogin'] is not empty and then just redirect to the specified url (also remember to erase that value after you use it).
