I tried this Drag-and-Drop File uploadfrom Aaron Vanston: https://codepen.io/aaronvanston/pen/yNYOXR

It works perfectly, all until I try to post it. I put the whole thing in a <form> tag and added a submit button, but after uploading an image and submitting it, both the $_POST and the $_FILES arrays are empty. I tried adding a regular file-upload input field, and that one seemed to work.

Does anyone know why the code linked above won't let me submit the file? Is there any way to fix this?

The <input>-Tag in the codepen was missing a name attribute. Adding it fixed it's functionality.

The Codepen contains only and solely the behaviour of the userinterface. There is no functionality implemented to send data anywhere...
