以下代码将按post_title 字段，数字。此代码将影响后端和前端帖子的主查询。

// Apply numeric post ordering for posts in admin and front end.
// Adapted from https://www.fldtrace.com/custom-post-types-numeric-title-order
function wpse247871_post_order( $wp_query ) {
    if ( $wp_query->is_main_query() && $wp_query->query[\'post_type\'] == \'post\' ) { 
        add_filter( \'posts_orderby\', \'wpse247871_orderby_post_title_int\' );
    }  
}  
add_filter(\'pre_get_posts\', \'wpse247871_post_order\');

// Cast the post_title field as an integer in SQL.
function wpse247871_orderby_post_title_int( $orderby ) {
    global $wpdb;
    return "({$wpdb->prefix}posts.post_title+0) ASC";
}
