php - Wordpress 查询仅显示置顶帖子

Question

以下是我的 wordpress 查询，我只想在其中显示置顶帖子，但查询未显示任何帖子。此外，我将两个帖子设置为置顶，以便检查该部分!!!!请告诉我如何修改此查询，以便它只显示置顶的帖子

<?php 
   $wp_query = null; 
  $wp_query =  new WP_Query(array(
 'posts_per_page' => 2,
 //'paged' => get_query_var('paged'),
 'post_type' => 'post',
'post__in'  =>  'sticky_posts',
 //'post__not_in' => array($lastpost),
 'post_status' => 'publish',
 'caller_get_posts'=> 0 ));

  while ($wp_query->have_posts()) : $wp_query->the_post(); $lastpost[] = get_the_ID();
?>

Answer 1

只显示置顶帖子的查询:

// get sticky posts from DB
$sticky = get_option('sticky_posts');
// check if there are any
if (!empty($sticky)) {
    // optional: sort the newest IDs first
    rsort($sticky);
    // override the query
    $args = array(
        'post__in' => $sticky
    );
    query_posts($args);
    // the loop
    while (have_posts()) {
         the_post();
         // your code
    }
}
