今天介绍代码方式，不使用默认的置顶：

这个例子中，手机端置顶两篇，电脑端置顶一篇，同时博客页面ID为19114。

// 置顶三篇文章
add_action( 'pre_get_posts', function($q){
    if(19114 == get_queried_object_id()){
        $stickies = array(165618,166278,161883);
        if ( wp_is_mobile() ) {
            $stickies = array(165618,166278);
        }
        $q->set( 'post__not_in', $stickies );
        if ( !$q->is_paged() ) {
            global $my_filter_executed;
            $my_filter_executed = false;
            add_filter( 'the_posts', function ( $posts ) use ( $stickies ){
                global $my_filter_executed;
                if($posts and !$my_filter_executed){
                    $term_stickies = get_posts( array('post__in' => $stickies, 'nopaging' => true) );
                    $posts = array_merge( $term_stickies, $posts );
                    $my_filter_executed = true;
                }
                return $posts;
            }, 10, 1 );
        }
    }
