Dropzone: handle multiple files

[jmsche]

It would be nice if Dropzone could handle multiple files.

I was expecting it would as its parent type is the FileType, that allows setting multiple option to true.

Yep, that's a good idea! I'm not sure how to handle it properly yet but that's a good idea :)

Probably like https://www.dropzonejs.com, with multiple query in ajax for upload each image and return a valid or error response.

is Multiple Files allowed or not yet ?

I plan to make multiple and chunked file uploads in one of my pilot project. At this moment I don't find any "official" direction about templating of UX modules (small prototypes). This is problem at my symfony collection type ux module too.

Hello,
I am having the same issue. I did a few things to make it work.
I will try to make it available to everyone as a package

Hello,

someone have the solution to do multiple upload?

[yassinehamouten]

Hello,

You can see how I make it work there https://github.com/yassinehamouten/ux-dropzone-multiple/tree/main/Resources. I tried to do it as a package, but stimulus does not call my controller. If someone has an idea...

I changed:

• in the form template I added "multiple" in the file input https://github.com/yassinehamouten/ux-dropzone-multiple/blob/3d282f520811ae720b0b194b7d28363eba6a1502/Resources/views/form_theme.html.twig#L6
• and in the controller.js https://github.com/yassinehamouten/ux-dropzone-multiple/blob/main/Resources/assets/src/controller.js

You can change the symfony ux-dropzone package and build your js. It will work on production

[yassinehamouten]

It's look like this if you take the css too

thank fou for your work, does it work if you use the DropzoneType:: class in your formType ?

@yassinehamouten this is interesting, I wasn't sure we could do it with the multiple attribute, good news! That would be a great PR if you wish :) !

@yassinehamouten Would it be ok for you when I create a PR with your changes?
