how about a WHERE clause.
Maybe something like:
$query = "SELECT WEEK(date) as week, count(*) as hits, listingID as lidcount FROM invotestotal WHERE WEEK(date) = 8 ORDER BY hits DESC";

I am trying to echo the ranking of votes (highest to lowest) that a product received in a given week. See example of desired output. In the query below, It's working great and outputs ID, votes, and week; however, I can't figure out how to get the ranking for a given week. In the example below, how would I be able to output values in the Ranking column for week 8 so that ID 1 is ranked 1, ID 3 is ranked 2, etc. Help?
