在Laravel中使用Dropzone上传后的成功消息

Question

Am using Dropzone to upload files in Laravel 4.2, Below is my function which process the files after uploading.

public function postDropFiles()
{
    $file = Input::file('file');

    $destinationPath = 'uploads/'.Auth::user()->username.'/files/'.date('Y-m-d');

    $extension = File::extension($file->getClientOriginalName());
    $filename =  time().str_random(12).'.'.$extension;

    $upload_success = Input::file('file')->move($destinationPath, $filename);


    if( $upload_success ) {
        return Response::json('success', 200);//->with('uploaded','Succesiful uploaded');
    } else {
       return Response::json('error', 400);
    }

}

The codes works fine , as you can see when response is 200 (success) am trying to pass variable name called "uploaded" (Commented) so that I can display the message to the user that the files successifully uploaded.

In my View I have something like this:

@if(Session::has('uploaded'))
    <div class="notice-box"><strong>{{Session::get('uploaded')}}</strong></div>
@endif

My aim is to create a session variable after uploading and then use it to display message in View. I would appreciate any help. By the way am new to Laravel.

IF USING NON AJAX REQUEST

Add it using the Session facade;

Session::flash('uploaded', 'Successfully uploaded.');

This will put it in the session for the next request and then be deleted.

IF AJAX REQUEST

Pass the message value through the JSON data you are passing back to the ajax request, such as;

Response::json(array('success' => true, 'message' => 'Successfully uploaded file.'), 200);

Edit: On error as recommended by itachi, this is so the error method in your ajax will be called.

Response::make(array('success' => false, 'message' => 'Error while uploading file.'), 400);

Then you can check the success flag, and then display the subsequent message wherever you want it to display via jQuery.
