Answer 1

首先，我建议你反复观看Laravel 5 Fundamentals，因为它是免费的。其他系列也提供了很好的信息。

其次，我建议你至少使用Sublime Text和一些有用的包，以便能够检查系统文件（命名空间，接口，继承树等等）的深度嵌套关系。如果您不能/可能不会，这位朋友将随时为您服务Laravel API

第三，AFAIK，Laravel Request构建在Symfony的请求组件上。由于您尝试将其核心功能之一作为非静态函数重载，因此您收到此错误。

另外，老实说，我不会将我的用户/客户端模型创建逻辑放入请求中。 Laravel为这种误解提供了一个很好的例子。在 App \ Services 文件夹中，您将找到Laravel oem用户模型的注册商服务。

让我们用不同的案例来检查问题。

但首先，基本......

让我们假设所有逻辑都应放在控制器内。

RegisterController.php

<?php namespace App\Http\Controllers;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Request;

class RegisterController extends Controller {
    public function create()
    {
        return view('Client.client');
    }

    public function store()
    {   
        $data = Request::all(); //requested data via Facade
        //prepare validatation
        $validation = Validator::make($data, [ 
                'fullname' => 'required|max:255',
                'email' => 'required|email|max:255|unique:users',
                ]);
        //validate
        if ($validation->fails())
        {
            return redirect()->back()->withErrors($v->errors());
        }
        // create the client
        Client::create([
            'fullname' => Request::input('fullname'),
            'email'    => Request::input('email'),
        ]);

        return \Redirect::route('Client.client')
        ->with('message', 'Record Inserted!');
    }

}

第二个解决方案

您可能愿意分离验证逻辑并应用一些依赖注入。

RegisterController.php

<?php namespace App\Http\Controllers;

use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Http\Requests\ClientFormRequest;

class RegisterController extends Controller {

    public function create()
    {
        return view('Client.client');
    }

    public function store(ClientFormRequest $request)
    {   
        // create the client
        Client::create([
            'fullname' => $request->input('fullname'),
            'email' => $request->input('email'),
        ]);

        return \Redirect::route('Client.client')
        ->with('message', 'Record Inserted!');
    }

}

ClientFormRequest.php

use Stringy\create;

use App\User;
use Validator;
use App\Http\Requests\ClientFormRequest;
class ClientFormRequest extends Request {

    public function authorize()
    {
        return true;
    }


    public function rules()
    {
        return [
            'fullname' => 'required|max:255',
            'email' => 'required|email|max:255|unique:users'
        ];
    }

}

第三种解决方案

您可能愿意更进一步，甚至将对象创建逻辑分离为服务，以便在任何地方使用它。现在您的请求文件将保持不变。然而，

RegisterController.php

use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Http\Requests\ClientFormRequest;
use App\Services\ClientRegistrar;

class RegisterController extends Controller {

    private $registrar;

    public function __construct(ClientRegistrar $registrarService)
    {
        $this->registrar = $registrarService;
    }
    public function create()
    {
        return view('Client.client');
    }

    public function store(ClientFormRequest $request)
    {   

        $newClient = $this->registrar->create($request->all());
        return \Redirect::route('Client.client')
        ->with('message', 'Record Inserted!')->compact('newClient');
    }

}

应用\服务\ ClientRegistrar.php

 use App\Client;
 use Validator;
 use Illuminate\Contracts\Auth\Registrar as RegistrarContract;

 class ClientRegistrar implements RegistrarContract {

    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return \Illuminate\Contracts\Validation\Validator
     */
    public function validator(array $data)
    {
        return Validator::make($data, [
           'fullname' => 'required|max:255',
        'email' => 'required|email|max:255|unique:users',
        ]);
    }

    /**
     * Create a new client instance after a valid registration.
     *
     * @param  array  $data
     * @return Client
     */
    public function create(array $data)
    {
        // create the client
        return Client::create([
                'fullname' => $data['fullname'],
                'email' => $data['email'],
            ]);
    }

 }

结论没有正确和最好的方法来解决问题。为您和您的项目规模保持最佳适用和适当的方式。
