Hello @simbu-g2t sorry for the delay.
What are you trying to upload?
And at this line it tries to get the Provider did you registered it?

from sonata-multiupload-bundle.

@simbu-g2t So what kind of provider are you trying to use?

• You want to use the image provider?
• Can you provide me your sonata_media.yaml?

from sonata-multiupload-bundle.

It's working if I add the provider(sonata.media.provider.image) at line number 51 in /vendor/silasjoisten/sonata-multiupload-bundle/src/Controller/MultiUploadController.php like $providerName = $request->query->get('provider','sonata.media.provider.image');

In your snippet you are setting a default for provider. if there is no query parameter it will use the default. This behaviour is not so graceful. The logic requires a registered provider otherwise the app has no idea how to handle file/image/video etc.

Are you using default "select provider" view from Sonata or are you trying to generate a direkt url to image multi upload?

from sonata-multiupload-bundle.

@simbu-g2t Okay so you are generating a direct multi upload link to the multi upload action. You need to pass the provider query parameter.

And for the selection of an provider go to the media grid/list view and it should be done automatically when you click on new
1.

2. This is the page to select Provider (to get the route you can use bin/console debug:router command) and create an link to that

Maybe see that: #56 (comment) There is an example for an custom Audio Provider and how to register that

from sonata-multiupload-bundle.

Thanks for your help @silasjoisten

from sonata-multiupload-bundle.

How to register the provider? Can you guide me or give the code?

FYI: I'm new to sonata and symfony

It's working if I add the provider(sonata.media.provider.image) at line number 51 in /vendor/silasjoisten/sonata-multiupload-bundle/src/Controller/MultiUploadController.php like $providerName = $request->query->get('provider','sonata.media.provider.image');

from sonata-multiupload-bundle.

Currently I'm using direct URL for multiple upload. It is better if we can able to select provider. I don't know how to do that. This is my sonata_media.yaml

# config/packages/sonata_media.yaml

sonata_media:
    # if you don't use default namespace configuration
    class:
        media: App\Application\Sonata\MediaBundle\Entity\Media
        gallery: App\Application\Sonata\MediaBundle\Entity\Gallery
        gallery_has_media: App\Application\Sonata\MediaBundle\Entity\GalleryHasMedia
    db_driver: doctrine_orm # or doctrine_mongodb, doctrine_phpcr it is mandatory to choose one here
    default_context: default # you need to set a context
    contexts:
        default:  # the default context is mandatory
            providers:
                - sonata.media.provider.dailymotion
                - sonata.media.provider.youtube
                - sonata.media.provider.image
                - sonata.media.provider.file
                - sonata.media.provider.vimeo

            formats:
                admin: { width: 100 , height: 100 , quality: 80}
                small: { width: 200 , quality: 80}
                medium: { width: 3000 , quality: 80}
                big:   { width: 500 , quality: 70}
        blog:  # the default context is mandatory
            providers:
                - sonata.media.provider.image
                - sonata.media.provider.file

            formats:
                admin: { width: 100 , height: 100 , quality: 80}
                small: { width: 200 , quality: 80}
                medium: { width: 3000 , quality: 80}
                big:   { width: 500 , quality: 70}

    cdn:
        server:
            path: /uploads/media # http://media.sonata-project.org/

    filesystem:
        local:
            directory:  '%kernel.root_dir%/../public/uploads/media'
            create:     false

from sonata-multiupload-bundle.

But I don't see the provider in that page, Anything need to add in config to see that?

from sonata-multiupload-bundle.

From the step 3, I followed this only

parameters:
    sonata.media.admin.media.controller: SilasJoisten\Sonata\MultiUploadBundle\Controller\MultiUploadController

Anything need to do after this?

from sonata-multiupload-bundle.

Do you have a custom provider?

from sonata-multiupload-bundle.

Please read the manual carefully again please you need to do some other things too. You need to override the provider and use a trait.

from sonata-multiupload-bundle.

No, I don't have custom provider right now. Currently I resolved with the below code(added provider in query param) in my sonata_admin.yaml. It's working now with direct URL and I removed the provider query from /vendor/silasjoisten/sonata-multiupload-bundle/src/Controller/MultiUploadController.php

# config/packages/sonata_media.yaml

sonata_admin:
    title: 'Sonata Admin'
    title_logo: images/logo.png
    dashboard:
        groups:
          media:
              label:                Media
              label_catalogue:      ~
              icon:            '<i class="fa fa-image"></i>'
              items:
                  - route:        admin_sonata_media_gallery_list
                    label:        Gallery
                  - route:        admin_sonata_media_media_list
                    label:        Media
                  - route:        admin_sonata_media_media_multi_upload
                    label:        Add Multiple Images
                    route_params:        
                      provider: sonata.media.provider.image

It should be better if I select the provider from media, But I don't know to create a custom provider

from sonata-multiupload-bundle.
