[fixed] Attachments on NS 6.1

[Delhaze]

When downloading attachments on NS 6.1 the filename is not passed correctly to the download, and is saved as attachment.php.

I found this, thought it might be of use.

There has been a lot of posts saying different things about using

header("Content-Disposition: attachment; filename=yourfilename");

to download files in both Netscape and IE. So I did a a bit of testing and here are my conclusive results:

Netscape works, with the correct filename in the download dialog, only if you DO have the 'attachment;' keyword, like so:
header("Content-Disposition: attachment; filename=yourfilename");

Because of a known bug, which you can read about at http://support.microsoft.com/support/kb/articles/Q281/1/19.ASP, IE only downloads, with the correct filename in the download dialog, if you DO NOT have the 'attachment;' keyword, like so:
header("Content-Disposition: filename=yourfilename");

Since you do not want to inconvience one half of users or the other, you need to be able to do both. There are 2 methods to do this.

-- First Method (For quick and sleazy hackers):
header("Content-Disposition: atachment; filename=yourfilename");
Note the one 't' in attachment. This bug, but it works on BOTH browsers. I recommed you do NOT use this method, as it is very bad practice for your code to depend on a bug. If it gets fixed, like it should be, your code is now broken.

-- Second Method (For responsible code monkeys)
Detect the browser, and add attachment accordingly. Since IE is the only one with the bug, that I know of, just isolate it, like so:

if (strstr($HTTP_USER_AGENT,"MSIE"))
$attachment="";
else
$attachment=" attachment;";
header("Content-Disposition:$attachment filename=yourfilename");
