How to return function processing response in Laravel?

Question

Laravel

Friends, I'm just getting into Laravel, and so far I came across such a problem

. I have a form on the "Card" page that creates cards, the form has an action on a certain "card / check" handler

Route::post('/card/check', 'App\Http\Controllers\[email protected]')->middleware(['auth'])->name('card');

When the function is working, I want to send a notification to the "Card" page that everything is fine or an error, but this return returns me to the "card / check" Tell me how to properly process forms in Laravel in order to return notifications or any other information, relatively speaking, to the same place we started data processing Thank you in advance!
return view('createcard', ['succses' =>$succses]);
