Building a Referral System with Laravel - php

Question

I've made a referral system on my laravel project v5.4 but I have 2 issues with that:
My users referral link will load index page of my website instead of loading register page. (How I fix it?)
When user register with referral link nothing will happen in database of the person who invited new user and also new user him/herself. (How I get info in both users tables?)
I simply used this tutorial to get my referral system:
https://brudtkuhl.com/building-referral-system-laravel/
This is my CheckReferral Middleware:
<?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);
}
}
This is my UserController
public function referral() {
$user = User::find(1);
return view('users.referral', compact('user'));
}
Here is my route:
Route::get('/referral', 'UserController#referral')->name('referral');
My 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,
]);
}
User Model
protected $fillable = [
'name', 'username', 'email', 'password', 'affiliate_id', 'referred_by',
];
And That's it!

Answer 1

if this is for registration the right way to do this is first in your routes you should have a optional input like ..
Route::get('/register/{referral?},'Auth\RegisterController#registerPage');
then in that controller
public function registerPage($referral=0)
{
return view with the $referral variable ..
}
in your view .. your form should look like this ..
<form action="/register/{{ referral }}" method="post" ..... >
back to your route ..
Route::post('/register/{referral},'Auth\RegisterController#doRegister');
in your controller again ..
public function doRegister(Request $request, $referral)
{
$request->merge(['referred_by' => $referral]);
}
so your referred_by is either 0 or other value .. it's up to you how you handle the validation ..

Answer 2

Add register page url in the value in this part -> url('/')
#if(!Auth::user()->affiliate_id)
<input type="text" readonly="readonly"
value="{{url('/').'/?ref='.Auth::user()->affiliate_id}}">
#endif

Answer 3

Question number 1:
I think you should add {{url('/register')}} here instead of {{url('/')}} to make it look this way:
#if(!Auth::user()->affiliate_id)
<input type="text" readonly="readonly"
value="{{url('/register').'/?ref='.Auth::user()->affiliate_id}}">
#endif
If that's how your register route endpoint is defined.
