forced PDF download, wrong name

Waire

this is based on the first tutorial file from the FPDF package (www.fpdf.org).
It's working, but the filename in the saveas dialog is always the name of the php file which creates the pdf... in this case, tuto1.pdf. (tuto1.php was the executed script)
What could the problem be? Oh, and it DOES WORK under Firefox! The problem shows up with IE6.

thanks

function CleanFiles($dir)
{
    //Delete temporary files
    $t=time();
    $h=opendir($dir);
    while($file=readdir($h))
    {
        if(substr($file,0,3)=='tmp' and substr($file,-4)=='.pdf')
        {
            $path=$dir.'/'.$file;
            //if($t-filemtime($path)>3600)
                @unlink($path);
        }
    }
    closedir($h);
}

require('../fpdf.php');
$pdf=new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);

CleanFiles(getcwd());
$pdf->Cell(40,10,"text");

// make tempfile

$file=basename(tempnam(getcwd(),'tmp'));
rename($file,$file.'.pdf');
$file.='.pdf';

$pdf->Output($file);

header('Content-type: application/pdf');
header("Cache-Control: cache, must-revalidate");   

header("Pragma: public");
header("Content-Length:". filesize($file));
header("Content-Disposition: attachment; filename=\"whatever.pdf\"");
set_time_limit(0);
readfile($file);

don't know if it matters, but my script worked fine using the same headers, only I did not put quotes around the file name. (I was doing pdf's, too).

i had the same problem in that a file called i.php would stream out the contents of a file for download, and the browser would ALWAYS try to save the file as i.php.

we used the headers below to fix the issue.

Hope it helps.

 header('Content-Description: File Transfer');
 header('Content-Type: application/force-download');
 header('Content-Length: ' . filesize($filename));
 header('Content-Disposition: attachment; filename=' . basename($file->name));

thanks atacus and coreyp! But... it seems the problem's been solved, well, partially at least.

The thing was some kind of caching problem. I deleted all cookies, history, temp files and voila it's working. I realized it when I went to a different box and it worked all good. Another guy's machine worked incorrectly though, and it was obviously the first time we entered the address, so I don't see how the caching problem could work in his case... (?)

Also it showed up that when running the script on our suse8.1 server, the file gets "damaged" during download. The one made on the server is okay though...
I'll let you know if I find it out, maybe it helps someone.
