So first off, we need to include the appropriate files in our index. Data URIs represent the data of the image.

Basically, what we want to do at the simplest level is put all the data URIs the user drags into the box into an array, and post it to a PHP file. To begin, we need to initiate some variables: This will mean when the user drops something onto the drop area we can run a function to do what we want to do.

We want to support multiple file uploads so we will run each in jQuery to run a function for each file dragged into the drag area. To make sure the upload button is positioned correctly, we check the position based on how many files are in the dropped files area.

First off, push the correct data into the array and move the dropped images so they appear to be overlapping.

One piece of this is the name we generate for the file, and the other is whether or not the file upload was successful. This data is separated by a colon so we have to separate it into an array and use the appropriate data.

We can then call this later so the user can still see his or her uploaded files when they leave and come back.

Our PHP file will be called upload. The data URI will be encoded using base We have to decode it to begin with by taking apart the data URI, grabbing the data and changing it as appropriate.

After that we find the mime type, create a random name, and move the file into a variable. From there we can upload the file to a server and show a success or failure message.
