Where is the action is pointing to in Laravel form - php

Question

PS: I am new to Laravel. And following this tutorial to create sample project
Everything is working fine.
But I am not able to figure out how data is inserted into the database.
here is the form code
<form method="post" action="{{url('products')}}">
{{csrf_field()}}
<div class="row">
<div class="col-md-4"></div>
<div class="form-group col-md-4">
<label for="name">Name:</label>
<input type="text" class="form-control" name="name" >
</div>
</div>
<div class="row">
<div class="col-md-4"></div>
<div class="form-group col-md-4">
<label for="price">Price:</label>
<input type="text" class="form-control" name="price">
</div>
</div>
</div>
<div class="row">
<div class="col-md-4"></div>
<div class="form-group col-md-4">
<button type="submit" class="btn btn-success" style="margin-left:38px">Add Product</button>
</div>
</div>
</form>
Here at the onsubmit action it is calling "{{url('products')}}" .
What is the mean of this? Can anybody help?
If you need any other code let me know.
web.php
<?php
Route::resource('products','ProductController');
Route::get('/', function () {
return view('welcome');
});
ProductController.php
<?php
namespace App\Http\Controllers;
use App\Product;
use Illuminate\Http\Request;
class ProductController extends Controller
{
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function index()
{
//
$products = Product::all()->toArray();
return view('products.index', compact('products'));
}
/**
* Show the form for creating a new resource.
*
* #return \Illuminate\Http\Response
*/
public function create()
{
//
return view('products.create');
}
/**
* Store a newly created resource in storage.
*
* #param \Illuminate\Http\Request $request
* #return \Illuminate\Http\Response
*/
public function store(Request $request)
{
//
$product = $this->validate(request(), [
'name' => 'required',
'price' => 'required|numeric'
]);
Product::create($product);
return back()->with('success', 'Product has been added');;
}
/**
* Display the specified resource.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function show($id)
{
//
}
}

Answer 1

{{url('/products')}} means url() function will return base url and whatever added inside that method will append to base ur;
for example my website url is https://stackoverflow.com/ then above method will return
https://stackoverflow.com/products
in your route you have to define
Route::resource('products','ProductController');
Laravel route will point to your controller and method and in method you have a logic to insert into database
for better understanding
url()
The url function generates a fully qualified URL to the given path:
Ref:

Also to learn more about route resource you can refer
https://laravel.com/docs/5.5/controllers#resource-controllers

Answer 2

What you are asking for is Generating Urls This means it uses your app base url with the other urls you have in the string argument. Therefore, url('products') is the same thing as http://yourwebsite.com/products as the action on your form i.e where the form will be submitted to.
The other counterpart is Urls for named routes I will add a caption here in case the document link breaks at any point:
You see. This means that in your one of your routes has that name which you use to generate a url.
Since some of these helper functions are new to you (supposing you are learning by following a tutorial), my recommendation is to open Laravel's documentation and see how things are by yourself.

Answer 3

This seems to be a Route::ressource called 'product' and redirecting to ProductController.
