仅在 Wordpress 中查询置顶帖子

Question

我有以下查询来收集粘性帖子。这在我实际上有粘性帖子时有效，但是当我没有粘性帖子时，它只会查询 10 个（无粘性）帖子。我如何调整查询以仅收集粘性帖子，如果没有找到，则什么也不做。谢谢

/* Get all sticky posts */
$sticky = get_option( 'sticky_posts' );

/* Sort the stickies with the newest ones at the top */
rsort( $sticky );

/* Get the 5 newest stickies (change 5 for a different number) */
$sticky = array_slice( $sticky, 0, 5 );

/* Query sticky posts */
$the_query2 = new WP_Query( array( 'ignore_sticky_posts' => 'false', 'post__in' => $sticky, 'post_type' => 'ad_listing' ) );
echo $the_query2->post_count;

发现加入这个if语句，只查询置顶帖！

/* Get all sticky posts */
$sticky = get_option( 'sticky_posts' );

    if (!empty($sticky)) {
    //Do the query etc.
    }
