How to permanently forward a variable from the controller to the view?

Question

PHP

See, I need that when passing a variable to the view from the controller

//тут - переменной email
   return view('personalOffice')->with('email', $_POST['email']);

I could get the value of the variable in it even when I return the view from somewhere else.
Those. in web.php file i want code like this

Route::get('/', function () {
    if (Auth::check()) {
        return redirect(route('personalOffice'));
    }
    return view('welcome');
})->name('welcome');

Route::view('/personalOffice', 'personalOffice')->middleware('auth')->name('personalOffice');

didn't stop me from getting the variable in the personalOffice view. That is, even if the user is redirected not because of a method in the controller, but because of the code in the web.php file, I need to be able to get the email variable in the personalOffice view.
How to implement all this?

Answer 1

given the code, just put $_POST['email'] right in the view :) It won't get any worse
