在Wordpress中顯示WP_Query的某些頁面的數組

Question

我試圖實現的是僅顯示循環中的特定頁面。 3頁某些頁面，不多，不少。

我已經嘗試了很多東西，但我無法完成它。

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

這樣做，據我所知，它顯示了一個頁面的數組，然後在那裏包含這些ID。

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

而這隻顯示一個確定的頁面，它不支持顯示不同ID的數組。

我敢肯定，我不是第一個有這種特定需求的人，我確信有一個相對簡單的方法來實現我想要達到的目標，但我不能拿出一個解決方案或找到一個。任何人都可以幫助我嗎？

非常感謝提前！

只是想知道使用get_pages（）而不是創建新的wp_query（）會更好嗎？

使用這小小的一段代碼就可以生成你想要的頁面列表..

<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變量的print_r你會得到下面的數組

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

希望這是你可以使用.. :) 只記得包括您的頁面ID的get_pages（）包括部分，而不是2,3,4多數民衆贊成他們已經...

Answer 2

這裏是2+個月大的問題的答案：

你想顯示某些頁面，以在foreach呼籲WP_Query每個頁面，這樣怎麼樣：

$certain_pages = array(100,102,104); 
foreach($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 */ 
} 

不用擔心多次調用循環，即使在這種規模下也無法察覺到這種效果。
