Mysql not saving slashes

[may]

I have this strange problem of saving file name.
I want to save the path of the file just uploaded.
The variable $uploadfile contains the whole path for the file as :

$uploadfile='E:\mydata\pop.jpg';

The problem is that my query written below does not save the '\' , even if i use addslashes it completely ignores it. any idea how can i save slashes in mysql?

$sql2="update adverts set login='$uploadfile'";
$rs2=mysql_query($sql2);

Use addslashes on the uploadfile variable:
[code=php:0]$sql2="update adverts set login='" . addslashes($uploadfile) . "'";[/code]
