Batch Upload Image and Create Model.

Upload multiple images at once, and create one model for each of them.

The model must have an attachment (in attributes "attachMany" OR "attachOne").

Frontend HTML upload button:

Use it in a toolbar for example

<button type="button" class="btn btn-primary oc-icon-upload" data-control="upload" data-url="<?= Backend::url('vendor/plugin/mymodel/onBatchUploadCreate') ?>">
       Upload Image & Create
</button>

JavaScript Upload Code

make sure "dropzone" from october js framework is loaded

this.$el.find('[data-control="upload"]').each(function(){
    var postUrl = $(this).data('url');
    if(postUrl && (postUrl != '')){
        var uploaderOptions = {
                    clickable: $(this).get(0),
                    method: 'POST',
                    url: $(this).data('url'),
                    paramName: 'file_data',
                    createImageThumbnails: false,
                    headers: {},
                    previewsContainer: t.$el.find('[data-control="upload-ui"] .upload-preview').get(0)
                    // fallback: implement method that would set a flag that the uploader is not supported by the browser
          };

          t.dropzone = new Dropzone($(this).get(0), uploaderOptions);
          t.dropzone.on('addedfile', t.proxy(t.uploadFileAdded));
          t.dropzone.on('totaluploadprogress', t.proxy(t.uploadUpdateTotalProgress));
          t.dropzone.on('queuecomplete', t.proxy(t.uploadQueueComplete));
          t.dropzone.on('sending', t.proxy(t.uploadSending));
          t.dropzone.on('error', t.proxy(t.uploadError));
          t.dropzone.on('success', t.proxy(t.uploadSuccess));
    }   
});
