Answer 1

Your code tried to refer to an element that doesn't exist in $_FILES array, I don't know which line because your error message didn't clearly specify it.

(Edit) I think it's in the line where you move uploaded file.

Dump $_FILES as follows to see what keys and values it contain, and see which one you actually want.

var_dump($_FILES);
