thank you,

you've need create request validation class new form request.

1. create new request class

app/requests/maprequest.php
,

namespace app\http\requests; use app\http\requests\request; class maprequest extends request {     public function rules()     {         return [             'lat' => 'required|min:2',             'long' => 'required',         ];     }     public function messages()     {         return [             'lat.required' => 'required message',             'lat.min' => 'minimum value message',             'long.required' => 'required message'         ];     } } 

2. use map request class controller method: example, mapcontroller:

   public function store(maprequest $request) {      // process logic here!  }
