Question

我想创建一个下拉列表，其中从数据库中检索数据，即下拉级别。下拉级别的值取自表级别。

我的注册控制器是这样的：

<?php

namespace App\Http\Controllers\Auth;

use App\User;
use Validator;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\RegistersUsers;

class RegisterController extends Controller
{
    use RegistersUsers;

    protected $redirectTo = '/home';

    public function __construct()
    {
        $this->middleware('guest');
    }

    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|max:255',
            'username' => 'required|unique:users',
            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|min:6|confirmed',
        ]);
    }

    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'username' => $data['username'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
        ]);
    }
}

我的注册用户（供应商）是这样的：

<?php

namespace Illuminate\Foundation\Auth;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Auth\Events\Registered;

trait RegistersUsers
{
    use RedirectsUsers;

    public function showRegistrationForm()
    {
        return view('auth.register');
    }

    public function register(Request $request)
    {
        $this->validator($request->all())->validate();

        event(new Registered($user = $this->create($request->all())));

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

        return redirect($this->redirectPath());
    }

    protected function guard()
    {
        return Auth::guard();
    }
}

我的注册视图是这样的：

<form method="post" action="{{ url('/register') }}">

    {!! csrf_field() !!}

    <div class="form-group has-feedback{{ $errors->has('name') ? ' has-error' : '' }}">
        <input type="text" class="form-control" name="name" value="{{ old('name') }}" placeholder="Full Name">
        <span class="glyphicon glyphicon-user form-control-feedback"></span>

        @if ($errors->has('name'))
            <span class="help-block">
                <strong>{{ $errors->first('name') }}</strong>
            </span>
        @endif
    </div>

    <div class="form-group has-feedback{{ $errors->has('email') ? ' has-error' : '' }}">
        <input type="email" class="form-control" name="email" value="{{ old('email') }}" placeholder="Email">
        <span class="glyphicon glyphicon-envelope form-control-feedback"></span>

        @if ($errors->has('email'))
            <span class="help-block">
                <strong>{{ $errors->first('email') }}</strong>
            </span>
        @endif
    </div>

    <div class="form-group has-feedback{{ $errors->has('password') ? ' has-error' : '' }}">
        <input type="password" class="form-control" name="password" placeholder="Password">
        <span class="glyphicon glyphicon-lock form-control-feedback"></span>

        @if ($errors->has('password'))
            <span class="help-block">
                <strong>{{ $errors->first('password') }}</strong>
            </span>
        @endif
    </div>

    <div class="form-group has-feedback{{ $errors->has('password_confirmation') ? ' has-error' : '' }}">
        <input type="password" name="password_confirmation" class="form-control" placeholder="Confirm password">
        <span class="glyphicon glyphicon-lock form-control-feedback"></span>

        @if ($errors->has('password_confirmation'))
            <span class="help-block">
                <strong>{{ $errors->first('password_confirmation') }}</strong>
            </span>
        @endif
    </div>

    <div class="row">
        <div class="col-xs-8">
            <div class="checkbox icheck">
                <label>
                    <input type="checkbox"> I agree to the <a href="#">terms</a>
                </label>
            </div>
        </div>
        <!-- /.col -->
        <div class="col-xs-4">
            <button type="submit" class="btn btn-primary btn-block btn-flat">Register</button>
        </div>
        <!-- /.col -->
    </div>
</form>

我收到了代码：https://github.com/InfyOmLabs/adminlte-generator/tree/5.3

代码的

，似乎是registerusers（供应商）调用中的寄存器视图

如何调用数据库中的表来存储变量并发送到查看寄存器？

如果我必须编辑注册用户（供应商）？

如何？

Answer 1

如果我理解正确，您需要覆盖showRegistrationForm()方法。因此，将此方法从供应商复制粘贴到RegisterController并在那里使用它：

public function showRegistrationForm()
{
    // Do something here.

    return view('auth.register');
}

另外，请勿在{{1}}目录中进行任何更改。

Answer 2

您不应在供应商的文件中编写任何代码，而是可以使用service injection或view composers来达到您的目的。
