Middleware for custom request - php

Question

I created my request in which I validate the data. Some of this data I need to convert to JSON.
For this, I decided to create middleware. But when I try to get a request in the controller, it doesn't have anything I added in the middleware.
This seems to be because it is not my own request 'MyRequest $request' that gets into the middleware. How can this be resolved?
middlevare
class TransformData
{
/**
* #param $request
* #param Closure $next
* #return mixed
*/
public function handle($request, Closure $next)
{
$next($request);
$request->merge(['user_id' => \Auth::user()->id]);
$request->merge(['select_products' => json_encode($request->select_products)]);
return $request;
}
}
my request is called OfferRequest, there are just validation rules
controller
class BaseController extends Controller
{
public function __construct()
{
$this->middleware('transform.offer.data')->only('store');
}
}
public function store(OfferRequest $request)
{
$all = $request->all();
dd($all); // there is nothing here that I added in the middleware
}
I added the middleware to the kernel - protected $routeMiddleware

Answer 1

Update your Middleware like the following :
TransformData.php
class TransformData
{
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle($request, Closure $next)
{
$request->merge([
'user_id' => \Auth::user()->id,
'select_products' => json_encode($request->select_products)
]);
return $next($request);
}
}
The above would work, but I would suggest you to use prepareForValidation() method link in form request class for update request data.
Using prepareForValidation() method you could add or update your request parameters.
OfferRequest.php
class AccountFilterRequest extends FormRequest
{
public function authorize()
{
return true;
}
public function rules()
{
//your rules
}
/**
* Modify the input.
*/
public function prepareForValidation()
{
$this->merge([
'user_id' => \Auth::user()->id,
'select_products' => json_encode($request->select_products)
]);
}
}
prepareForValidation() method is executed before validation so you can add new data or update data and validate those.
