Is it possible for the user to drag a *folder* of images?

[MorningZ]

Got the plugin all working nice and playing nice with my .NET based site.... I guess my last concern as I get ready to roll out is user's and confusion over Drag and Drop

What would it take to be able to allow the plug to accept the user dragging a folder that has images to it rather than the images itself?

Is that isn't even possible, is there any hook in place that I can react to the user dragging something invalid into the drop zone (like for instance, hit them with a growl asking them to drag images, not folders) ?

Thanks in advance.... great work on this plugin, can't wait to have it "live" on my site

In PHP, assuming it gets to post(), I would think you'd first have to recognize it's a directory with is_dir(), then send each file in the directory to handle_file_upload() similar to the way post() already does it with multiple files.

but the plugin flat out rejects the drag... so it never gets to "post"

There is no browser support for folder drag&drop:

so does that conversation/explanation also rule out any possibility of any kind of event raised to tell the user they can't do that?

You can bind an event handler to the fileuploaddrop event (or the drop event of the dropZone) and check event.dataTransfer.files and display info to the user accordingly:

$('#fileupload').bind('fileuploaddrop', function (e) {
    // check event.dataTransfer.files for valid file objects
});

Thanks, that did the trick

$('#fileupload').bind("fileuploaddrop", function (e) {
      if (event.dataTransfer.files.length === 0) {
             AA.Utils.Message("#U_Message", "Please only drop images or zip files of images into the drop zone", "bad");
      }
});

Added folder drag&drop support with commit cd0c9ed
This is currently only supported by Google Chrome.

Hi I got the plugin all set up and the drag and drop is working as expected.The folder drag and drop option is working on chrome but,I would like to recreate the folder structure on the backend.What part of the code should I modify so that I can send the array of files with the full relative path of the file names to recreate the folder structure.Any help would be greatly appreciated.Thanks
