Laravel 5.2 validation redirect with old input

In reference to this stockoverflow question

I created a new request with php artisan make:request ApplicationFormRequest

public function rules() { 
   return ['first_name' => 'required']
}

I also have a controller as such,

public function store(ApplicationFormRequest $request){
   //empty
}

I have seen an example on stackoverflow with 

return Redirect::to('/')->withInput();

they seem to put their validation together with the controller, but I am not sure how to go about it this way.

Where would I put that? How do I retrieve old input even with validation fail?

EDIT you see my controller is empty, it validate automatically with the rule i set at ApplicationFormRequest. when it failed it automatically redirect to the view where the input is submitted with error 

@foreach ($errors->all() as $error)
    <li class="alert label">{{$error}}</li>
@endforeach

but I am unable to fill the input with the input user just submitted, I try to do 

<input type="text" value="{{ old('first_name') }}" \>

but this give me error Use of undefined constant

In Laravel 5.2, if the view forms are not being populated with old data sent back from a custom Request class, do the following:

1) Place all routes related to the request in the route group, which should be included in 5.2

Route::group(['middleware' => ['web']], function () {
    // routes here
});

2) Run php artisan key:generate

EDIT: This fix may not be applicable for versions other than 5.2.

You can do this by checking if a value is available in the POST or GET array first. If it is available in the POST or GET array, then echo it in the value attribute of the input.

Your input field would look something like this:

<input type="text" name="first_name" value="if (Input::has('first_name')){ @echo Input::get('first_name');}" \>

as the error say use of undefined constant. Your errors variable is not in the scope of view. check what you are doing wrong.

use Docs for further reading.
