php - 使用 Laravel 构建推荐系统

Question

我在我的 laravel 项目 v5.4 上做了一个推荐系统，但我有两个问题:

1. 我的用户推荐链接将加载我网站的索引页面，而不是加载注册页面。 (我该如何解决？)
2. 当用户使用推荐链接注册时，邀请新用户的人以及新用户他/她自己的数据库中不会发生任何事情。 (如何在两个用户表中获取信息？)

我只是使用本教程来获取我的推荐系统: https://brudtkuhl.com/building-referral-system-laravel/

这是我的 CheckReferral 中间件:

<?php

namespace App\Http\Middleware;
use Illuminate\Http\Response;
use Closure;

class CheckReferral
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
     public function handle($request, Closure $next)
     {
         if( $request->hasCookie('referral')) {
             return $next($request);
         }
         else {
             if( $request->query('ref') ) {
                 return redirect($request->fullUrl())->withCookie(cookie()->forever('referral', $request->query('ref')));
             }
         }
         return $next($request);
     }
}

这是我的UserController

public function referral() {
      $user = User::find(1);
      return view('users.referral', compact('user'));
    }

这是我的路线:

Route::get('/referral', 'UserController@referral')->name('referral');

我的RegisterController

<?php

namespace App\Http\Controllers\Auth;

use App\User;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;
use Cookie;
use DB;

class RegisterController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Register Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles the registration of new users as well as their
    | validation and creation. By default this controller uses a trait to
    | provide this functionality without requiring any additional code.
    |
    */

    use RegistersUsers;

    /**
     * Where to redirect users after registration.
     *
     * @var string
     */
    protected $redirectTo = '/home';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest');
    }

    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return \Illuminate\Contracts\Validation\Validator
     */
    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|string|max:255',
            'username' => 'required|string|max:255|unique:users',
            'email' => 'required|string|email|max:255|unique:users',
            'password' => 'required|string|min:6|confirmed',
            'g-recaptcha-response' => 'required|captcha',
        ]);
    }

    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return User
     */
    protected function create(array $data)
    {

        $referred_by = Cookie::get('referral');

        return User::create([
            'name' => $data['name'],
            'username' => $data['username'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
            'affiliate_id' => str_random(10),
            'referred_by'   => $referred_by,
        ]);
    }

用户模型

protected $fillable = [
        'name', 'username', 'email', 'password',  'affiliate_id', 'referred_by',
    ];

就是这样!

Answer 1

如果这是为了注册，正确的方法是首先在你的 route 你应该有一个可选的输入，比如..

Route::get('/register/{referral?},'Auth\RegisterController@registerPage');

然后在那个 Controller 中

public function registerPage($referral=0)
{
    return view with the $referral variable ..
}

在您看来..您的表单应该是这样的..

<form action="/register/{{ referral }}" method="post" ..... >

回到你的路线..

Route::post('/register/{referral},'Auth\RegisterController@doRegister');

再次在你的 Controller 中..

public function doRegister(Request $request, $referral)
{
    $request->merge(['referred_by' => $referral]);
}

因此您的 referred_by 是 0 或其他值..这取决于您如何处理验证..
