Here is my Register Controller.
<?php
namespace Lea\Http\Controllers\Auth;
use DB;
use Lea\User;
use Lea\Http\Controllers\Controller;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;
use Illuminate\Http\Request;
use Cookie;
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 = '/';
/**
* 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, [
'fname' => 'required|string|max:255',
'lname' => 'required|string|max:255',
'referral' => 'string|max:255',
'username' => 'required|string|max:255',
'email' => 'required|string|email|max:255|unique:users',
'password' => 'required|string|min:6|confirmed',
// 'tracking_id' => 'required',
]);
}
/**
* Create a new user instance after a valid registration.
*
* #param array $data
* #return \Lea\User
*/
protected function create(array $data, Request $request)
{
// printing here referral Link
echo $request()->ref;
// $referred_by = Cookie::get();
// print_r($referred_by);
die;
return User::create([
'fname' => $data['fname'],
'lname' => $data['lname'],
'username' => $data['username'],
'email' => $data['email'],
'password' => bcrypt($data['password']),
'affiliate_id' => str_random(10),
// 'referred_by' => $referred_by,
'identity' => $data['identity'],
'dob' => $data['dob'],
'board_id' => $data['board_id'],
'class_id' => $data['class_id'],
'subject_id' => $data['subject_id'],
'institute' => $data['institute'],
'address' => $data['address'],
'city' => $data['city'],
'std_mobile' => $data['std_mobile'],
'father_name' => $data['father_name'],
'father_mobile' => $data['father_mob'],
'ipadress' => \Request::ip(),
]);
}
}

Answer 1

When you have an URI such as /register?ref=mh2HPLpVSn you can retrieve ref like this:
$request()->ref
in your controller! I believe you can also use $request()->has('ref') to determine if it's present in the URI.
Hope this helps you!!

Answer 2

In laravel 6+ inside controller you can use like
$request->get('ResourcePath')

Answer 3

You can get your parameters using Request access.
Here one example for get your ref code:
public function register(Request $request)
{
$allParams = $request->all();
$refParam = $request->ref;
dd($allParams, $refParam);
...
}

Answer 4

public function showRegister(Request $request) {
var_dump(request->ref)
}
then you can do things like validation and so on, another possiblity is to change the template of your register form and add a hidden field with the refcode from the ref param and handle the whole request in your register method.
