Customize Laravel Fortify Registration Error

Question

I am currently building my first laravel application for a school project. I am using Laravel Jetstream, which might now was the best choice but its too late to change that now.

In the CreateNewUser.php File after the Validation the "create"-function does the following:

return User::create([...]);

I changed it to

if(condition) {
   $user = new User([...]);
   $user->save();
   return $user;
} else {
   return view('error);
}

I am now facing the problem that in case of the condition not applying, laravel gives me the following error:

This does make sense to me, but after a few hours of looking through the code and browsing the interet, I havent been able to figure out how I can customize the code so I can return an error page.

I would be very happy if anyone of you could help me as I am now quite sure how to go on at this point.

Edit: After reviewing the question a second time, I noticed its maybe not clear why I am doing it that way. My Problem is, that I need to sync the user over a pivot table with a school after creating it. Maybe there is also a way to do that while creating the user? If there is, please let me know.

Answer 1

You could likely sync your user of the to the pivot table in RegisteredUserController.php after the $user returned before the redirect to login:

public function store(Request $request,
                          CreatesNewUsers $creator): RegisterResponse
    {
        event(new Registered($user = $creator->create($request->all())));

        //use the newly created $user here

        $this->guard->login($user);

        return app(RegisterResponse::class);
    }
