Thanks,
What you are saying makes sense to me.
I will shortly explain what I am trying to do:
On my page all users have they own username and password.
When I translate some document, I upload that document into specific users
'mailbox' on my website. So when user logs in, he can see the list of files
I uploaded for him and he can download them.
I will not attempt to delete file after download any more, as you said, it's
not a good idea.
Now, since I keep tracking changes that user makes in my database (i.e. when
I upload file, it is recorded in database), I would like to do the tracking
of downloaded files.
So when user downloads the file, I would like the php script to insert that
record into database
(i.e. RECORD_NO:216, USER: some_user, DATE OF DOWNLOAD:13.03.2007.,
FILE_DOWNLOADED: some_filename).
In that way, I could visit my website once a week and even manualy delete
files that user "took away" to his computer.
Is this possible to do in some way, or is it too complicated?
Thanks for your efforts
