How to insert data with logged in user id? Laravel-6 - laravel

Question

I want to submit data to bidding table with logged in user id and auction id from product show method.
This is how my tables are in relation.
Is it good to use ProductController or should I create another controller for bidding table?
Product show blade
#extends('layouts.app')
#section('content')
<div class="container">
<div class="my-3 border">
<div class="row">
<div class="col-md-5">
<img src="/storage/images/{{$product->image}}" alt="" style="width: 100%;">
</div>
<div class="col-md-7">
<h2>{{$product->name}}</h2>
<p>{{$product->description}}</p>
<span>Category: {{$product->category->name}}</span><br>
<span class="text-right">Auction Ends: {{$product->auction->deadline}}</span>
<div class="price">Initial Price: {{$product->price}}</div>
{!! Form::open(['action' => 'BiddingsController#create', 'method' => 'POST', 'enctype' => 'multipart/form-data']) !!}
<div class="form-inline">
{{Form::number('bidamount', '',['class' => 'form-control mr-1', 'placeholder' => 'Place your bid'])}}
{{Form::submit('Place Bid', ['class' => 'btn btn-primary'])}}
</div>
{!! Form::close() !!}
#endsection
Bidding controller
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Bidding;
class BiddingsController extends Controller
{
public function index()
{
$biddings = Bidding::all();
return view('products.show' ,compact('biddings', $biddings));
}
public function create()
{
//
}
public function store(Request $request)
{
//
}
public function show(Bidding $bidding)
{
//
}
}

Answer 1

In a Laravel 6 app, you can get the Logged in user using the auth() helper.
$authUser = auth()->user();

Cordially

Answer 2

You can check anytime your logged details by Auth!
Everywhere and from anywhere you can use Auth::user()->id;
example:
for getting logged user id in controller check by!
dd(Auth::user()->id);
If needed just use Illuminate\Support\Facades\Auth in the very beginning of controller.
