Receiving a string value from client to server

Question

I am working on Android along with yii-2 php. From my app I am sending some photos in a file using an api call. Along with it I am sending a reference number as shown below.

@Multipart
@POST("installation/photo/save")
Call<ApiResponse> uploadImage(@Header("Authorization") String token, @Part("ref_no") RequestBody ref_no, @Part MultipartBody.Part file);

The call is initialized as shown below

Retrofit retrofit = RetrofitClient.getClient();

RetrofitInterface retrofitInterface = retrofit.create(RetrofitInterface.class);

RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);

MultipartBody.Part body = MultipartBody.Part.createFormData("uploaded_file", file.getName(), requestFile);

RequestBody ref_no = createPartFromString("<ref_no>");

ref_no = createPartFromString(installationDetails.getReferenceNo());

Call<ApiResponse> call = retrofitInterface.uploadImage("Bearer " + Common.getAuthKey(mContext),ref_no, body);

            call.enqueue(new Callback<ApiResponse>() {
                @Override
                public void onResponse(Call<ApiResponse> call, Response<ApiResponse> response) {
                    if (response.isSuccessful()) {

                        Log.d(TAG, response.body().getStatus());

                        if (response.body().getStatus().equals("OK")) {

                            snapManager.updateSnapStatus(AssetsManagementContract.SnapEntry.COLUMN_SITE_SNAP, snap.getSnapName(), Constants.SNAP_SYNCED);
                            Intent broadcastSyc = new Intent();
                            broadcastSyc.setAction(Common.GetSyncImageAction());
                            broadcastSyc.putExtra("STATUS", true);
                            mContext.sendBroadcast(broadcastSyc);
                            sendImage(mContext);

                        }
                        else{
                            snapManager.updateSnapStatus(AssetsManagementContract.SnapEntry.COLUMN_SITE_SNAP, snap.getSnapName(), Constants.SNAP_CLOSED);
                        }

                    } else {
                        snapManager.updateSnapStatus(AssetsManagementContract.SnapEntry.COLUMN_SITE_SNAP, snap.getSnapName(), Constants.SNAP_CLOSED);
                        Log.d(TAG, "Error");
                    }
                }

Working of app

1. User note down the details of installation and take pictures
2. On closing the form two API's are called i) API to save/upload installation data to server ii) API to save/upload images to the server.

The images are uploaded when the Installation API response is returned OK.

OkHttp Log

When the images are pushed to the server below is the call in ok http

Server Side

At server side below is API code through which images are saved.

public function actionSavephoto()
{
    try {
        $count = 0;
        foreach ($_FILES as $f) {
            $dd = pathinfo($f['name']);
            if (!isset($dd['extension']) || !in_array($dd['extension'], array('jpg', 'png', 'gif'))) {
                return ['status' => 'ERROR', 'uploaded_files' => $count, 'message' => 'Invalid File'];
                break;
            }
            if (move_uploaded_file($f['tmp_name'], Installations::UPLOAD_FOLDER . $f['name'])) {
                $count++;
                return ['status' => 'OK', 'uploaded_files' => $count];
                break;
            } else {
                return ['status' => 'ERROR', 'uploaded_files' => $count];
                break;
            }

        }

    } catch (Exception $x) {
        return ['status' => 'ERROR', 'message' => $x->getMessage()];
    }
}

The response after var_dump($dd) below is the response that generates.

array(4) {
  ["dirname"]=>
   string(1) "."
   ["basename"]=>
   string(37) "28372230019211U_1517370655_site_1.jpg"
   ["extension"]=>
     string(3) "jpg"
   ["filename"]=>
   string(33) "28372230019211U_1517370655_site_1"
  }

In response there is no reference number. How can I get the reference number at server side?

Any help would be highly appreciated.

Answer 1

Check if there is $_POST['ref_no'] present at server side after the call.
