onUpload UploadListener notwork!!

[nephilimdie]

hi, i've problem when i try to use listener. Maybe is my fault. I'm in symfony 2.3 with postgresSQL. I try to use that with sonata media.

        $request = $event->getRequest();
        $file = $this->getFiles($request->files);
        die(var_dump($file));
        $gallery = $request->get('gallery');
        $file = $request->files->get('upload');
...etc

my service

services:
  ## post pre update event after persist object
  media.upload_listener:
      class: 'Kdig\MediaBundle\EventListener\UploadListener'
      arguments: [ '@service_container' ]
      tags:
          - { name: container.event_listener, event: oneup_uploader.post_persist, method: onUpload }

"die()" not work.
Can you explain me why?

thanks in advance
regards
Stefano

Hi Stefano

I guess this is the EventListener you are talking about. Am I right?

Why do you call a getFiles method on the $this object, where there is no such method available? You can get the file from the event object like this:

$file = $event->getFile();

Could you verify if the constructor of the Listener gets called?

thank you for your quickly answer.
yep, is right, is my project, for my university. trying to create archaeological data system.

is one of chance that i choose trying to understand the problem.
i cheanged with var_dump($request); but the issue is the same.

I use this for my template from blueimp page
index.html.twig

it is as if the listener is not called.

There are several possibilities why the Listener does not get called.

• The listener somehow doesn't get registered. You can verify that by calling $> php app/console container:debug and see if the media.upload_listener appears in this list.
• There is no file in the request. Try to add a var_dump(count($files)); after Line 18 in the BlueimpController in your vendor folder. It should return a number > 0.
• If the Controller in the previous point does not get called, check the Ajax-Request from the Client to the Server: Is the url correct? Is at least one file attached? What is the response?

But you should probably first check this one: In the docs the name of the tag is kernel.event_listener and not container.event_listener like in your example.

<tag name="kernel.event_listener" event="oneup_uploader.post_persist" method="onUpload" />

Try change the tag-name to kernel.event_listener.

i am sorry. When i changed container to kernel is started to work well. Now i see the response.
Thank you for everything and for your time! :)

Hello !
Can we see what there is in your onUpload method please !

[sheeep]

@aymerixp Please specify your problem. I'm happy to help.

If you think it could be a problem with the bundle itself, ask here or in a new ticket. If you think it's more question-like, consider posting your problem to Stackoverflow, so others can profit from it too. (Remember tagging your question with Symfony2 and upload or file-upload).

[aratinau]

I asking here because my fronted return me "Error Empty file upload result".
So i understand there is no response returned so i would like to know what return !

[sheeep]

so i would like to know what return !

There was already an issue and a Stackoverflow thread regarding return values for jQuery File Uploader. Furthermore, take a look at the official documentation and the Return custom data to the Frontend section of this bundle. You should end up with something like this.

namespace Acme\HelloBundle\EventListener;

use Oneup\UploaderBundle\Event\PostPersistEvent;

class UploadListener
{
    public function onUpload(PostPersistEvent $event)
    {
        $file = $event->getFile();
        $response = $event->getResponse();

        $response['files'] = array(
            array(
                'name' => $file->getFilename(),
                'url' => //...
                'thumbnail_url' => //...
                // more keys ..
            )
        );
    }
}

There reason why this bundle does not return anything by default is the fact, that you could implement a custom JavaScript function to handle return values. You're not bound to this scheme.

That exactly what I was looking for ! Thank you a lot ! It works great !
