 public $rules = [
         'name' => 'required',
         'reg_no' => 'required',
         'contact_no' => 'required|digits:value=10',
         'address' => 'required',
         'map_lat' => 'required',
         'map_lng' => 'required',
     ];

'contact_no' => 'required|digits:10' It will be like this. Other than that everything is right.
