Your problem is occurring because you're enclosing the index in single quotes.
Change
$query .= ",;" . $_POST['bid_sub_desc$i'] . ":";
to
$query .= ",;" . $_POST['bid_sub_desc'.$i] . ":";

If you can change the names on the form to 
arrays, it would make your life much easier. Then 
instead of checking for $_POST['bid_sub_desc' 
.$i], you could use $_POST['bid_sub_desc][$i]
