I have used some free code for listing files for download, but I want to
send an email to the administrator when the file has been downloaded. I
have got some code in here that does it, but it will not print in the
username or email amddress of the person doing the download - which I am
collecting from a form on the previous page. I can get the name and
email address to print out normally, just not into the email sending
body. I have attached code below:
