update database with javascript?

[Anon]

here is my code:
if(mysql_affected_row() != 0)
{
print("<SCRIPT LANGUAGE=\"JavaScript\">
if(confirm(\"This Company Already Has A Backorder For This Products. Add To Quantity?\"))
{

//If Confirm = Yes then I want to Update bQty How do I do this

<?
$query = "update backordersmain set bQty = '$new_qty' where bItemNumber = '$bItemNumber' ANd bCustId = '$bCustId'";
$mysql_result = mysql_query($query, $mysql_link);
?>
url = \"./addBackorders.php\";
window.location.href = url;
}
else
{
url = \"./addBackorders.php?addBackorder=Second&bQty=$bQty&bItemNumber=$bItemNumber&bCustId=$bCustId&bCancelDate=$bCancelDate&bEnterDate=$bEnterDate&bStatus=open\";
window.location.href = url;
}
</script>");
}

I think, that it is impossible because of principle. The JavaScript is processed at the client side whereas the PHP is processed at the server side. It have to be done in two phases one, which will generate some HTML page to be shown in browser where the user will press some button or link which will process second phase with update command.

I have been changing that script a million ways and can't seem to get it right. So I kinda figured what you said
