Link home-made php script to addtorrent.php

[Hightmar]

Hello, I am making a script to add a torrent from a self-made form.
I have to do it like this, Rutorrent and Rtorrent are on a machine that uses a VPN. So I'm going through another machine which is on the same local network.

In my script I call addtorrent.php so that the torrent is added automatically to Rtorrent and is started. I'am not very good in code and I don't understand what I have to send as information to the $_REQUEST variable (I think it is this one). I tried to give it the $_FILE information but it doesn't seem to be that.

I manage to send my file to the server but when the script calls addtorrent.php I get "File not found."
Result URL :
https://domain.tld/upload/addtorrent.php?result[]=Failed&name[]=file.name.torrent&

Anyone know how I can link my script correctly to addtorrent.php please?
