Query Relationship in Laravel 9 User Registration-CodePudding

I have a Region model that has a relationship with my User model. I need a user to select which region they are in when registering. I'm getting an Undefined variable $regions error.

RegisterUserController.php

...
class RegisteredUserController extends Controller
{

    /**
     * Display the registration view.
     *
     * @return \Illuminate\View\View
     */
    public function create()
    {
        return view('auth.register');
    }

    /**
     * Handle an incoming registration request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\RedirectResponse
     *
     * @throws \Illuminate\Validation\ValidationException
     */


    public function store(Request $request)
    {
        $request->validate([
            'first_name' => ['required', 'string', 'max:255'],
            'last_name' => ['required', 'string', 'max:255'],
            'company_name' => ['required', 'string', 'unique:tenants,name'],
            'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
            'password' => ['required', 'confirmed', Rules\Password::defaults()],
        ]);

        $tenant = Tenant::create([
            'name' => $request->company_name,
        ]);

        $user = User::create([
            'region_id' => $request->region_id,
            'first_name' => $request->first_name,
            'last_name' => $request->last_name,
            'email' => $request->email,
            'role' => 'admin',
            'password' => Hash::make($request->password),
            'tenant_id' => $tenant->id,
        ]);

        $user->sendEmailVerificationNotification();

        event(new Registered($user));

        Auth::login($user);

        $regions = Region::all();

        return redirect(RouteServiceProvider::HOME, compact('regions'));
    }
}

register.blade

...<!-- Region -->
<div >
    <select wire:model="region_id" id="region_id" name="region_id"
            >
        <option>Choose Region</option>
        @foreach($regions as $reg)
            <option value="{{$reg->id}}">{{$reg->region_name}}</option>
        @endforeach
    </select>
</div>
...

CodePudding user response：

Redirect parameters are used to represent the parameters in the route URL

for example

// For a route with the following URI: profile/{id}
 
return redirect()->route('profile', ['id' => 1]);

for passing data at redirection you can use with

return \Redirect::route(RouteServiceProvider::HOME)->with(['regions'=>$regions]);

and in blade or controller you can access data using Session::get('regions')

...<!-- Region -->
<div >
    <select wire:model="region_id" id="region_id" name="region_id"
            >
        <option>Choose Region</option>
       @if(session()->has('regions'))
          @foreach(session()->get('regions') as $reg)
            <option value="{{$reg->id}}">{{$reg->region_name}}</option>
          @endforeach
        @endif
        
    </select>
</div>

CodePudding user response：

You'll want to pass your regions from the controller action that renders the view instead:

    public function create()
    {
        return view('auth.register', [
            'regions' => Region::all(),
        ]);
    }
