[PHP] Need advice on downloading files and databases
Hello everybody, Newbie here...basically I need to develop a site that will allow users to download files, e.g Word docs, XL sheets, and I would like to know whether it is better to store the entire file in a database, or just the filepath, or even whether I need a database at all. Is it possible to link to a file on a remote server if the file isn't in the root directory? Any advice gratefully received.

[PHP] fopen over a network
Hello,
I'd like a user to be able download a file from a file server on my LAN.
Using works ok, but this simply displays
the file in the browser and I want to force the download dialog box to appear.
So now i have , and i want to do something like
fopen("file://server/directory/filename",rb") but i just get an invalid argument
warning.
Am i on the right track?Is there a way around this?
Cheers,
Dara

Re: [PHP] fopen over a network
Thanks for the advice lads but I realise I should have been clearer. I know about
header(etc..) so displaying the download dialog isn't the problem, it's how to get to
the file on the file server and then open it. The file server isn't a web server.
This is probably ridiculously easy so I hope I'm not wasting your time. I don't want
to@use the 'right-click' option, I want something similar to@opening attachments in
hotmail for example. Here's what I have anyway.
Cheers, Dara

[PHP] validate querystring
Hello, I have a query string like this http://server/download.php?fname=name_of_remote_file. The script runs and displays a file download dialog box. Is there a way of validating the querystring to ensure that a user doesn't try something like fname=. or fname=.. or fname=? or fname=/, which enable the user to see the contents of the remote directory, without resorting to a load of 'if' statements.Are there any other special characters i should be aware of?

[PHP] global variables
Is it "better" to pass variables through functions or to simply declare them as global within the function's scope? The variables in this particular case are things like MySQL database connections and tablenames.

[PHP] content type header for downloading files
I have the following headers in download.php which forces a download dialog box to be
opened when a user clicks on a desired file:
header("Content-type: application/octet");
header("Content-Length: $filelength"); header("Content-Disposition: attachment;
filename=".basename($fname).";");
This works fine with IE, but Mozilla adds a '.php' extension to the filename if i
choose the save option, and asks me to choose which application to use if I want to
open the file. The files are binary.
Do I need to change the content-type header? If so, to what? If not, what do I do?
Thanks, Dara

Re: [PHP] content type header for downloading files
No, that doesn't change anything with Mozilla, and as for IE the file is automatically
displayed in the browser. I actually want the Dialog Box to appear. I think Mozilla
doesn't know what to do with 'application/octet.'

Re: [PHP] content type header for downloading files
$fname is the name of the file i want to download. It works in IE, as in the name of
the file to be downloaded appears correctly in the dialog box. I changed
'application/octet' to 'application/octet-stream' and this had no effect.
