检查laravel中的验证是否失败

public function store(Request $request)
{
    $validatedData = $request->validate([
        'name' => 'required|max:255',
        'email' => 'required|email|unique:users',
        'password' => 'required|min:8',
    ]);

    // 如果验证通过，可以继续处理其他逻辑
    // ...
}

@if ($errors->any())
    <div class="alert alert-danger">
        <ul>
            @foreach ($errors->all() as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
@endif

public function store(Request $request)
{
    $validator = Validator::make($request->all(), [
        'name' => 'required|max:255',
        'email' => 'required|email|unique:users',
        'password' => 'required|min:8',
    ]);

    if ($validator->fails()) {
        // 验证失败
        return redirect()->back()->withErrors($validator)->withInput();
    }

    // 如果验证通过，可以继续处理其他逻辑
    // ...
}
