注册表单验证问题

Question

I'm adding a validation to my sign up form , the validate code is working but the errors don't shows up in the page

PHP code

 public function postSignUp(Request $request)
{
        $this->validate($request, [
            'email'=> 'required|email|unique:users',
            'first_name'=> 'required|max:120',
            'password' => 'required|min:4'
            ]);

        $email = $request['email'];
        $first_name = $request['first_name'];
        $password = bcrypt($request['password']);

        $user =  new User();

        $user->email = $email;
        $user->first_name = $first_name;
        $user->password = $password;

        $user->save();

        Auth::Login($user);

        return redirect()->route('dashboard');
}

Welcome.blade.php code

@section('content')
@if(count($errors) > 0)
<div class="row">
    <div class="col-md-6">
        <ul>
            @foreach($errors->all() as $error)
                <li>{{$error}}</li>
                @endforeach
        </ul>
    </div>
</div>
@endif

the php code is working because if i tried to register with an email that already taken it wont register but the error is that errors are not showing up in the welcome page

You are not passing the error messages back to the view. As stated at documentation

    if ($validator->fails())
    {
        return redirect('dashboard')->withErrors($validator);
    }
