php - how to manage a special error with special message in laravel -

i'm using laravel 5.4. , need handle error. imagine user logged in , opened 2 windows (his profile). when user click on logout in window, have still logout button in window, , clicking on that, laravel show csrf_token error page.

my logout in not ajax , submitting form /logout how can handle error special message or redirect home without error logout controller? (not of csrf_token errors, controller).

logout form :

i submit form clicking on logout button using jquery:

<form id="logout-form" action="/logout" method="post" style="display: none;">     <input type="hidden" name="_token" :value="token"> </form> 

and logout method in controller :

public function logout(request $request) {     $this->guard()->logout();     $request->session()->flush();     $request->session()->regenerate();     return redirect('/'); } 

in app\exceptions\handler.php return user form new valid csrf token, page refreshed , logout button not exist.

public function render($request, exception $exception) {     if($exception instanceof tokenmismatchexception)    {        return redirect()                ->back()                ->with('your msg');    }    return parent::render($request, $exception);  } 

this looking like, page refreshed.

don't replace post get. not safe , standard.
