Old Input: Flashing Input To The Session

$request->flash();

$request->flashOnly(['username', 'email']);

$request->flashExcept('password');

The flash method on the Illuminate\Http\Request class will flash the current input to the session so that it is available during the user's next request to the application.

You may also use the flashOnly and flashExcept methods to flash a subset of the request data to the session.
