php: is it possible to change the name of a download?

eantoranz · 05-25-2006, 03:32 PM

I'm working on downloading the attachments of mails (working with IMAP).

I want to know if it's possible to set the name of the file the person will download? I know the Content-type can be set with a header so the web agent knows what type of file is being downloaded... however, is there a way I can tell the agent the file name? I didn't find an http header to do it on rfc2616.

You're right, I'm not sure it can be done in the http headers. I'd typically use mod-rewrite to achieve that sort of thing.

i have an asp script which includes

Code:

Response.AddHeader "Content-Disposition","attachment; filename=Blah blah blah.csv"

so i'd assume the Content-Disposition header would work jstu as well when php generated.

The good source is always the documentation.... Extracted from http://php.net/manual/en/function.header.php

header('Content-type: application/pdf');

// It will be called downloaded.pdf
header('Content-Disposition: attachment; filename="downloaded.pdf"');

// The PDF source is in original.pdf
readfile('original.pdf');
?>

For the exact rfc, chapter 15.5 of rfc2616 ("Content-Disposition Issues") refers to rfc2183
