仅在Wordpress中查询粘贴帖子

Question

我有以下查询来收集粘贴帖子。当我实际上有粘贴帖子时，这可以工作，但是当我没有粘贴帖子时，它只查询10个（无粘性）帖子。我如何调整查询以收集只有粘性的帖子，如果没有找到，只是什么都不做。感谢

/* 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;

Answer 1

通过添加此if语句，发现只查询粘贴帖子！

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

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