Someone should make a PR.

Hi,
I'm ready to work on this PR but first I need to clarify if it is still a valid feature request. I have found some articles which shows how to upload a single file (http://updates.html5rocks.com/2012/04/Processing-XHR2-file-uploads-in-PHP) or multiple files (https://github.com/Integralist/XHR2-Multiple-File-Upload--with-PHP-) using XHR2 but they are both posting the files inside a FormData object (not the JavaScript File object) which means $_FILES gets populated as it should.
My question is: is there a valid use case of using the File object instead of the more comfortable FormData?

it has very low priority because, you can create something like this

        var formdata = new FormData();
        formdata.append("fieldName", file);

        var xhr = new XMLHttpRequest();
        xhr.open("POST", "url", true);

        xhr.send(formdata);

but as far as it's part of spec's it should be supported

[kepten]

The spec says nothing about how to implement direct BLOB uploading on the server side (e.g. which HTTP header stores the filename, size, etc.) which makes this very client-side dependent. The original request was to populate the FileBag property, but my opinion is that this property should handle only files uploaded as part of a form and should not include a custom implementation of this XHR2 mechanism.
But if someone wants to use this feature, he/she should be able to use $this->get("request")->getContent(true) (instead of php://input) and handle the upload manually.

I'm closing this issue because in 3 years it hasn't registered any activity. If this feature is still desired, a new issue can be created to discuss about including it in Symfony 3. Thank you!
