I am just trying to do a simple upload script to upload a text file and then get the contents of it. This should be really easy but for some reason $note_contents comes back blank and I just can't figure it out at all. Its really confusing and kind of frustrating. I have no idea why this isn't working at all... The file is not being uploaded and /tmp exists
