您可以按照以下步骤执行此操作：

将自定义元框添加到帖子中创建一个函数，使用save\\u post操作保存元数据，将“meta\\u key”查询参数添加到您正在使用的任何查询中将其放在主题功能中。php文件：

function register_post_assets(){
    add_meta_box(\'featured-post\', __(\'Featured Post\'), \'add_featured_meta_box\', \'post\', \'advanced\', \'high\');
}
add_action(\'admin_init\', \'register_post_assets\', 1);

function add_featured_meta_box($post){
    $featured = get_post_meta($post->ID, \'_featured-post\', true);
    echo "<label for=\'_featured-post\'>".__(\'Feature this post?\', \'foobar\')."</label>";
    echo "<input type=\'checkbox\' name=\'_featured-post\' id=\'featured-post\' value=\'1\' ".checked(1, $featured)." />";
}

function save_featured_meta($post_id){
    // Do validation here for post_type, nonces, autosave, etc...
    if (isset($_REQUEST[\'_featured-post\']))
        update_post_meta(esc_attr($post_id, \'_featured-post\', esc_attr($_REQUEST[\'_featured-post\']))); 
        // I like using _ before my custom fields, so they are only editable within my form rather than the normal custom fields UI
}
add_action(\'save_post\', \'save_featured_meta\');

    $args = array(
        \'meta_key\' => \'_featured-post\', // include underscore prefix in key name
        \'meta_value\' => 1
    );
    // The number of posts displayed would be determined under Settings->Reading
    query_posts($args);

    if(have_posts()): while(have_posts()): the_post();
        // Do your bidding here

    endwhile; else:

    endif;

    $args = array(
        \'posts_per_page\' => 5,
        \'meta_key\' => \'_featured-post\',
        \'meta_value\' => 1
    );

    $featured = new WP_Query($args);

    if ($featured->have_posts()): while($featured->have_posts()): $featured->the_post();
        the_title();
        the_content();
    endwhile; else:

    endif;

我试着运行这段代码，这对我在主页上显示我的特色帖子，以供案例研究自定义帖子类型有很大帮助。非常感谢。

         <?php $args = array( 
                \'post_type\' => \'case_studies\',
                \'posts_per_page\' => 1,
                \'meta_key\' => \'featured_post\',
                \'meta_value\' => 1
            );

            $featured = new WP_Query($args);

            if ($featured->have_posts()): while($featured->have_posts()): $featured->the_post(); ?>
