add some function in our ValidationController.php

ValidationController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;

class ValidationController extends Controller
{
    // create new function to show the form login as a our index
    public function ShowForm(){
      return view('loginex');
    }
    // create function for our Validation
    public function ValidateForm(Request $request){
      print_r($request->all());
      $this->validate($request,[
          'username'=>'required|max:10',
          'password'=>'required'
      ]);
    }
}

loginex.blade.php

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">

  <body>

    @if (count($errors) > 0)
      <div class="error">
        <ul>
          @foreach($errors->all() as $error)
            <li>{{ $error }}</li>
          @endforeach
        </ul>
      </div>
    @endif

    <?php
      echo Form::open(['url'=>'/validation']);
     ?>
     <table border="1">
       <tr>
         <td>
           Login
         </td>
       </tr>
       <tr>
         <td>
           username
         </td>
         <td>
           <?php echo Form::text('username'); ?>
         </td>
       </tr>
       <tr>
         <td>
           Password
         </td>
         <td>
           <?php echo Form::password('password'); ?>
         </td>
       </tr>
       <tr>
         <td>
           Password
         </td>
         <td>
           <?php echo Form::submit('login'); ?>
         </td>
       </tr>
     </table>
     <?php echo Form::close(); ?>
  </body>
</html>

web.php

Route::get('/validation', 'ValidationController@ShowForm');
Route::post('/validation', 'ValidationController@ValidateForm');

Next, try to access our validation on your browser following this command
