Laravel不会存储offsetSet（）定义的值

Question

I have this code

class DonorsController extends Controller
{
    //Some code

    public function donorAddSave(Request $request){
      if ($request->file('DonorPhoto')->isValid()) {
        $destinationPath = 'uploads'; // upload path
        $DonorPhotoURL = date_timestamp_get(date_create()).'.'.$request->file('DonorPhoto')->guessExtension();
        $request->file('DonorPhoto')->move($destinationPath,$DonorPhotoURL);
      }

      $request->offsetSet('UserID',1);
      $request->offsetSet('DonorPhotoURL','/'.$destinationPath.'/'.$DonorPhotoURL);

      if(!$request->has('DonorPrefix')){
        $request->offsetSet('DonorPrefix', 'Mx.');
      }

      $donor = \App\Donor::create($request->all());
      return redirect('/donor/'.$donor->DonorID);
    }
}

When I tried return $request->all() to see whether the value of DonorPrefix, UserID, and DonorPhotoURL has been stored in the array of requests or not, the returned JSON seems to have all of these three variables.

{
"DonorCitizenID": "1000000000000",
"DonorPrefix": "คุณ",
...
"UserID": 1,
"DonorPhotoURL": "/uploads/1465963777.png",
"DonorPhoto": {}
}

But when I tried return $donor, which is the object of the Donor, defined its value by the $donor = \App\Donor::create($requests->all());, the value of UserID and DonorPhotoURL is NOT stored, but the DonorPrefix does have the value of Mx. Here are the JSON for $donor:

{
"DonorCitizenID": "1000000000000",
"DonorPrefix": "คุณ",
...
"updated_at": "2016-06-15 04:16:47.000",
"created_at": "2016-06-15 04:16:47.000",
"DonorID": 39
}

(The ... represents some data omnitted for cleaner snippet)

I am sure the database itself has the column name of DonorPhotoURL and UserID, but it doesn't still store the values.

Make sure your App\Donor model has the field in $fillable in order for mass assignment to work.
