試したこと

試しにこのように変更してみたのですが特に変化はなく、$errors自体を受け取れていないのだと思いますがその原因がわかりませんでした。

php
1<!--@if ($errors->any())-->
2    <div class="alert alert-danger">
3        <ul>
4            @foreach ($errors->all() as $error)
5            <li>{{ $error }}</li>
6            @endforeach
7        </ul>
8    </div>
9<!--@endif-->

補足情報（FW/ツールのバージョンなど）

laravel 5.7

追記
このようにすると

php
1protected function validator(array $data)
2    {
3
4        $validate = Validator::make($data, [
5            'screen_name' => ['required', 'string', 'max:255', 'unique:users'],
6            'name' => ['required', 'string', 'max:255'],
7            'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
8            'password' => ['required', 'string', 'min:6', 'confirmed'],
9        ]);
10
11        dd($validat->errors()->all());
12
13        return $validate;
14    }

array:3 [▼
  0 => "The メールアドレス must be a valid email address."
  1 => "The パスワード must be at least 6 characters."
  2 => "The パスワード confirmation does not match."
]

このような結果が出ます

trait RegistersUsersをこのように変更しましたが、エラー内容は空のままでした。また、back()を使用しているのにフォームの内容は空になります。view側ではoldを記載済みです。
追記

php
1
2/*trait RegistersUsers*/
3public function register(Request $request)
4    {
5
6        $validate = $this->validator($request->all());
7
8        if ($validate->fails()) {
9            //dd($validate->errors());
10            return redirect()->back()->withInput()->withErrors( $validate );
11        }
12
13        
14        event(new Registered($user = $this->create($request->all())));
15
16        $this->guard()->login($user);
17
18        if ($response = $this->registered($request, $user)) {
19            return $response;
20        }
21
22        return $request->wantsJson()
23                    ? new Response('', 201)
24                    : redirect($this->redirectPath());
25        
26    }

$errorsをデバッグで内容確かめてください。

googleの検証でみるということでしょうか？コンソールなどに特にエラーは出ていなかったです。

PHPコードとしてのデバッグですよ。デバッガを使うか、Laravelならdd() またはdump()

bigbox267

2020/06/27 12:10

@if ($errors->any()) <div class="alert alert-danger"> <ul> @dd($errors->any()); @foreach ($errors->all() as $error) <li>{{ $error }}</li> @endforeach </ul> </div> @endif このように記載したのですが、if文の中が実行されないので(　$errors->any()　)自体が帰ってきていないように思います。 if文の外でdd( $errors )とした場合 Illuminate\Support\ViewErrorBag {#255 ▼ #bags: [] } と出力されます。 dd(　$errors->any()　)とした場合は [] のみ出力されます。
