[RESOLVED] header issue

I'm using IE7 and Firefox 2 and a script that creates a csv file to download.
This works in both browsers:

header("Content-Disposition: attachment; filename=sms_template.csv");

but this only works in IE:

$file_name = "sms_template";

header("Content-Disposition: attachment; filename={$file_name}.csv");
or
header("Content-Disposition: attachment; filename=" . $file_name . ".csv");

either of the above will download the file but without the .csv extension in Firefox.

Any ideas?

Many thanks

What about

header("Content-Disposition: attachment; filename=$file_name.csv");

Hi Kudose

Thanks for the reply.

Did not work i'm affraid. I have also tried the string as a variable and it will still not work???

Try surrounding the filename with double quotes in the header.
