Recently, I needed to remove a specific post from a blog page. Here's how I did it.
[php]
add_filter( 'genesis_custom_loop_args', 'wps_exclude_post' );
function wps_exclude_post ( $args ) {
$args['post__not_in'] = array(6586); //Post ID
return $args;
}
[/php]
This code adds an argument to the WordPress query called 'post__not_in' which takes an array of post IDs. So, I could just create a laundry list of posts I don't want in; however, in my case I only needed to exclude one.
As always, this code goes in functions.php.
