在我的网站上，我使用自定义的帖子类型来实现一个稍微复杂一点的版本。
我的要求是：；
标题上的富文本可以在“特色项目”（此处未涉及）之间切换的JavaScript动画，可以方便地从后端为管理员用户编辑特色项目，可以将特色项目链接到我们网站上的任何内容，无论是文章；博客《新闻邮报》；物种概况或术语表条目我认为CPT是前进的方向；这是我在定制WP安装的管理区域开发的界面。
自定义帖子类型本身的代码非常简单。我在中创建了一个文件夹plugins 调用的目录sf-featured-items 并创建了一个名称类似的php文件。
这是完整的代码。它看起来比实际情况复杂得多！

增加的复杂性可能是您不需要的—文章的链接。回顾过去，我本可以完全不使用它，只需使用富文本编辑器的内置超链接功能。
前端的代码也很简单：
创建辅助post查询(WP_Query)featured-itemposts_per_page => 3;<?php while ( $query->have_posts() ) : $query->the_post(); ?>
显示帖子，根据需要修改格式（下面代码中的格式非常复杂，因为我在互联网上看到了一个我喜欢的美学示例）<?php $query = new WP_Query(
array(
\'post_type\' => \'featured-item\',
\'posts_per_page\' => 3,
\'meta_query\' => array( array( \'key\' => \'_thumbnail_id\' ) )
)
);
?>
<div id="featured" >
<?php
$li = \'\';
$content = \'\';
$count = 1;
?>
<?php while ( $query->have_posts() ) : $query->the_post(); ?>
<?php
if ($count == 1) {
$li .= \'<li class="ui-tabs-nav-item ui-tabs-selected" id="nav-fragment-\'. $count .\'"><a href="#fragment-\'. $count .\'"><p>\'. get_the_title() . \'</p><span>\'. get_the_content() .\'</span></a></li>\';
$content .= \'<div id="fragment-\'. $count .\'" class="ui-tabs-panel" style="">
\'. get_the_post_thumbnail($post->ID, \'indexheader-thumb\') .\'
<div class="info" >
<p>\'. get_the_title() . \'</p>
<h2><a href="\'. get_post_meta( $post->ID , \'link_to_post\', TRUE ) .\'" >\'. get_the_content() .\'</a></h2>
</div>
</div>\';
} else {
$li .= \'<li class="ui-tabs-nav-item" id="nav-fragment-\'. $count .\'"><a href="#fragment-\'. $count .\'"><p>\'. get_the_title() .\'</p><span>\'. get_the_content() .\'</span></a></li>\';
$content .= \'<div id="fragment-\'. $count .\'" class="ui-tabs-panel ui-tabs-hide" style="">
\'. get_the_post_thumbnail($post->ID, \'indexheader-thumb\') .\'
<div class="info" >
<p>\'. get_the_title() . \'</p>
<h2><a href="\'. get_post_meta( $post->ID , \'link_to_post\', TRUE ) .\'" >\'. get_the_content() .\'</a></h2>
</div>
</div>\';
}
$count++;
?>
<?php endwhile; ?>
<?php wp_reset_query(); ?>
<ul class="ui-tabs-nav">
<?php echo $li; ?>
</ul>
<!-- First Content -->
<?php echo $content; ?>
</div>
