在Wordpress中显示WP_Query的某些页面的数组

Question

我试图实现的是仅显示循环中的特定页面。 3页某些页面，不多，不少。

我已经尝试了很多东西，但我无法完成它。

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

这样做，据我所知，它显示了一个页面的数组，然后在那里包含这些ID。

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

而这只显示一个确定的页面，它不支持显示不同ID的数组。

我敢肯定，我不是第一个有这种特定需求的人，我确信有一个相对简单的方法来实现我想要达到的目标，但我不能拿出一个解决方案或找到一个。任何人都可以帮助我吗？

非常感谢提前！

只是想知道使用get_pages（）而不是创建新的wp_query（）会更好吗？

使用这小小的一段代码就可以生成你想要的页面列表..

<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> 

如果你在$ special_tab变量的print_r你会得到下面的数组

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

希望这是你可以使用.. :) 只记得包括您的页面ID的get_pages（）包括部分，而不是2,3,4多数民众赞成他们已经...

这里是2+个月大的问题的答案：

你想显示某些页面，以在foreach呼吁WP_Query每个页面，这样怎么样：

$certain_pages = array(100,102,104); 
foreach($certain_pages as $a_page) { 
    $special_tabs = new WP_Query('page_id='.$a_page); 
    /* (sample) loop goes here */ 
    if ($special_tabs->have_posts()) : while ($special_tabs->have_posts()) : $special_tabs->the_post(); 
     the_content(); 
    endwhile; endif; 
    /* loop ends */ 
} 

不用担心多次调用循环，即使在这种规模下也无法察觉到这种效果。
