@AndrewBentleyAug 11.2022 — #If you really want to add something to the Request object, it's possible: $request->request->add(['key' => 'value']); but I would advise against it. It's better to get the request's values, merge them with any of your own and then use the resulting variable: $result = array_merge($request->all(), ['myKey' => 'myNewValue']); Post::create($result);
