windows 10 file upload and permissions php - php

Question

I'm having trouble moving uploaded files, the problem seems to be a permissions problem, any help would be much appreciated. I'm using windows 10 and I've change my temp folder in php.ini to a custom folder in xampp directory and when I check this temp folder the file isn't there either, so it seems that it isn't even being uploaded to them temp. Please help.

Answer 1

The file will be deleted from the temporary directory at the end of the request if it has not been moved away or renamed.

Answer 2

The problem seemed to have been my methods and not anything to do with permissions. I was was using values stored in the session to pass to the move_uploaded_file() function, once I did it directly from the POST request it worked fine. Is it that the move_uploaded_file() needs to be called from a POST request? Anybody care to shed some light on this, please do as I'd love to learn what happening behind the scenes.
