Problem with dialog box in IE

[sponge.nika]

I have an attachement

<a href="http://mydomain.com/attachment.php?&C=cd80f871f7e8d4dfjz&id=8">CV.docx</a>

The name of CV.docx in the server is "cd80f871f7e8d4dfjz.docx", the system changed the name when file was uploaded.In attachment.php I get the attachement "Real Name" and "Changed name" from database .
After that

header("Content-type: application/octet-stream");            
header("Content-disposition: attachment; filename=$RN");
$file=file_get_contents("attaches/".$FN);
echo $file; 

Where $RN is the "Real Name".
And $FN is the Changed Name(Name in the server)

So when I click on a link a dialog box is displayed with "Open", "Save" and "Cancel" buttons.
If I save the file it works good.
But when I try to open the file with IE, this messages occurs

The file could not be found.
(C:\...\CV[1].docx\)

With other browsers this method is works.

is it necessary to use IE?..if it works with other browsers, then there's nothing to it i guess..if you really want to use IE, then try using scripts that the browser supports..that way, your page won't be ruined..

Comment out the header lines, and out put the expected variables are the values different between ie and other browsers?

You also may want to remove the first & from

?&C=cd80f871f7e8d4dfjz&id=8

the & is for additional variables since c is the first one the & is not necessary and could cause some error.

?C=cd80f871f7e8d4dfjz&id=8
