Quite a while back Jake Jancar created a simple PHP class, called Dropbox Uploader that provided the ability to upload files to Dropbox. Amit Banerjee created a full script which, loaded on a server server running PHP 5.2+, allowed users to upload files to a Dropbox folder via a simple browser based uploader. You can read about this and even get the simple single file uploading app at AddictiveTips.com. I like the script and decided to play around with it some. I soon came up with a demo app that uses the HTML5 file API and Jake Jancar's Dropbox Upload class to implement a version that allows multiple file uploads using jQuery's Ajax. You can select multiple files or drag and drop files for upload. Demo password is: default
