wordpress - 在 WordPress 中使用 WP_Query 显示某些页面的数组

Question

我想要实现的目标是仅循环显示某些页面。 3 个特定页面，不多也不少。

我尝试了很多事情，但就是无法完成。

<?php
    $special_tabs = new WP_Query(array ('post_type'=>'page','post__in'=>array(100,102,104)))
?>

据我了解，它的作用是显示一个页面数组，然后也包含这些 ID。

<?php
    $special_tabs = new WP_Query('page_id=100');
?>

并且这只显示某一页，不支持显示不同ID的数组。

我确信我不是第一个有这种特定需求的人，并且我确信有一种相对简单的方法可以实现我想要实现的目标，但我就是想不出解决方案或找到一个。有人可以帮我解决这个问题吗？

非常感谢!

只是想知道使用 get_pages() 之类的东西是否会比创建新的 wp_query() 更好？

使用这一小段代码，您可以生成所需的页面列表..

<ul>
<?php $special_tabs = get_pages ('sort_column=post_title&echo=0&include=2,3,4&title_li='); ?>
<?php 
foreach ($special_tabs as $tab) {
  $title = $tab->post_title;
  echo "<li>".$title."</li>";
}
?>
</ul>

如果您对 $special_tab 变量执行 print_r，您将得到以下数组

</php
echo"<pre>";
echo print_r($special_tabs);
echo"</pre>";
?>

希望这是你可以使用的东西..:)只需记住在 get_pages() 包含部分中包含您的页面 ID，而不是已经包含的 2,3,4...
