[FX.php List] [OFF] Restricting web directory/downloads via FM?

[Leo R. Lundgren]

Sure, no problem! I suggest you start by making a basic solution like the one described with a script that 1) takes a username and password and checks the database, 2) readfile()'s the file if the authentication is successful.

Either you could make the script get all three parameters (username, password, filename) in one go (the client would have to make the link include the parameters in the URL), or you could make the script first present a login box and then do the above when the user submits the form on it.
