I want to exclude some posts from the home page. So I want to use meta data, and filter all posts that are signed by meta_value=0. Like this:
$args = array( 'posts_per_page'=>28, 'meta_query' => array( array( 'key' => 'show_on_home', 'value' => '0', 'compare' => 'NOT LIKE' ) ) ); $query = new WP_Query( $args );
So, if I sign some post with meta_key=0 it will not apear.
The problem is that I have a lot off posts that don't have meta data at all, and I don't want to filter them.
