Feat. req.: sort files before upload

[rockaut]

It would be nice to have an option for sorting files before upload e.g. for sorting by file size.

Doesn't sound like a very requested feature to put into the core. You can always add that or any other functionality on top of the basic Plupload, using events. We are working on providing more handy interfaces to access options and data dynamically.

Could you, or anyone explain more or post an example of how to accomplish this? I want to upload each file in reverse order and don't see how to.

Thanks

I hacked the plupload.js to get it to upload files in reverse order. Clearly, this is not how plupload.js was meant to be used, but it got the job done. I'm posting it here for anyone else looking for a quick hack.

$diff plupload.js
            if (this.state == plupload.STARTED) {
                // Find first QUEUED file
-               for (i = 0; i < files.length; i++) {
+               //Hack to reverse the upload order.
+               for (i = (files.length - 1); i >= 0 ; i-- ){
+                // orig: for (i = 0; i < files.length; i++) {
                    if (!file && files[i].status == plupload.QUEUED) {
                        file = files[i];
                        file.status = plupload.UPLOADING;

You don't have to hack plupload to do this (although there is nothing wrong with that approach if you are happy with it). You can bind a FilesAdded event handler before you call your uploader's init() function. Sort the 'files' array inside your FilesAdded event handing function - the files array will be passed into that function.

This technique works because event handlers are called in the order they are registered. This includes all of plupload's event handlers - they are bound in the init() call. So binding a FilesAdded handler to sort the files array before calling init() means you can rearrange the 'files' array before the plupload routines get their hands on it and start the upload.

Thanks for the feedback. I was sure there must be a more "correct" way to do it, ie, without changing plupload's code itself. But in my context, a drupal module, my way ended up being easier.

It will be nice if pluploader can support this as it is a common requirement to sort by file name, size, time etc.
