Post order by meta value and then date

[reckoner41]

Hi,

I am working on setting up a category page with featured posts first by assigning them an order based on a custom value 'featured' and a number value (1,2,3 etc).

My php is a bit rusty and this is what I have right now, the problem is that it only shows posts that have a featured custom value. If there is none assigned then it won't show in the category. I would prefer to show the three featured items first, then have a full list below, maybe by alpha order, maybe by date or whatever I choose.

What do I need to add to the query to make this happen.

Thanks in advance.


/** order by featured */

add_action('genesis_before_loop', 'custom_sort');
function custom_sort () {
if (is_category('3')) {
global $query_string;
query_posts($query_string . "&orderby=meta_value&meta_key=featured&order=asc") ;
}
}
