How to enable my upload form and php file for my apache server?

Question

Im trying to upload files to my apache server over http with curl.

I have a simple upload.php file in the root directory of my server and also a "submit" page on my server that is just a simple upload form.

How can I link the two to work together so that I can upload files onto my server? Or is the .php file enough to upload my file onto the server?

When I execte my curl command with -v I get the following output:

root@glennvds-VirtualBox:/home/glennvds# curl -F 
‘data=@~/home/glennvds/Desktop/link.txt’ http://xx.xx.xx.xx/upload.php -v
Warning: setting file ~/home/glennvds/Desktop/link.txt’  failed!
