Laravel | Errors validation returning null - development

Laravel | Errors validation returning null

Yesterday I started with Laravel, currently busy with my first project, a simple news page.

Unfortunately, I’ve met some problems while validating my post request, I’ve tried to search on Google for my issue… And I tried to use those fixes, but strange enough I had no result.

The problem is:
When I post data the normal ‘form page’ will be shown without any errors. I’m aware that I have double error outputs, it’s just for the test.

What do I want to reach?
I want that the validation error will be shown

routes.php

<?php

Route::group(['middleware' => ['web']], function() {

Route::get('/', function() {
    return redirect()->route('home');
});

Route::get('/home', [
    'as' => 'home',
    'uses' => 'HomeController@home',
]);

Route::get('/add_article', [
    'as' => 'add_article',
    'uses' => 'HomeController@add_article',
]);

Route::post('/add_article', [
    'as' => 'add_article.newarticle',
    'uses' => 'HomeController@post_article',
]);

});

HomeController.php

<?php

namespace AppHttpControllers;

use IlluminateHttpRequest;

use AppHttpRequests;

use AppNews;

class HomeController extends Controller
{

public function home(News $news) 
{
    $articles = $news->orderBy('id','desc')->take(3)->get();
    return view('home.home')->with('articles', $articles);
}

public function add_article()
{
    return view('home.add_article');
}

public function post_article(Request $request)
{

    $this->validate($request, [
        'title' => 'required|max:64',
        'content' => 'required|max:2048',
    ]);

    // $newNews = new News;
    // $newNews->title = $request->title;
    // $newNews->content = $request->content;
    // $newNews->save();
}

}

I hope someone can help me to resolve this issue!
Thanks in advance.
