[wp-hackers] show 2 random posts from the last 20 posts from the Featured category

[Joan Artés]

Another thing that you can do is to generate two numbers with the rand()
function (between 0 and 19) and then make two queries with the offset
parameter respectively:

$query1 = new WP_Query( 'offset'=$offset1 );
$query2 = new WP_Query( 'offset'=$offset2 );
