我已经为我的Wordpress特色文章编写了一个简洁的响应滑块（请随意使用）：

query_posts(array

它选择一个自定义类别并返回自定义数量的帖子。问题是，它将按创建帖子的顺序显示帖子。
I want to choose my own order, 这样我就可以选择先显示哪些帖子等等。
So, is it possible to select which order the returned posts are displayed? 可能通过针对特定ID？
理想情况下，我希望为第一篇文章设置一个自定义ID（直接在代码中），然后按照返回的顺序显示其余部分。这可能吗？
如果您选择回复，请用代码示例详细说明，谢谢阅读。

为了实现你的愿望，你必须提前拿到帖子。在给定ID列表的情况下，无法在SQL中指定任意顺序。
query\\u posts（）创建另一个主查询，抛出主查询。由于您正在执行此操作，因此可以使用get\\u posts（）返回帖子列表。
$posts = get_posts( array(
\'post_type\' => \'page\',
\'orderby\' => \'menu_order\',
\'order\' => \'ASC\',
\'post__in\' => (array) get_option(\'henrik_feat_pages\'),
\'showposts\' => (int) $featured_num
) );
然后，
$posts_by_id = array();
foreach( $posts as $post ) $posts_by_id[$post->ID] = $post;
现在，您有了一个按ID索引的post对象数组，您可以遍历有序列表并从该列表中选择post：
global $post;
foreach( (array) get_option( \'henrik_feat_pages\' ) as $post_id ) {
$post = $posts_by_id[$post_id];
setup_postdata( $post )
// ... Template code as if you were in the loop.
}
Update
上面的循环替换了主循环。所以与其写作
<?php if (have_posts()) : while (have_posts()) : the_post();
<?php /** Code in loop **/ ?>
<?php endwhile; endif; ?>
要启动循环，我们使用：
global $post;
foreach( (array) get_option( \'henrik_feat_pages\' ) as $post_id ) {
$post = $posts_by_id[$post_id];
setup_postdata( $post );
/** Code in loop **/
}
这是使用稍微不同语法的等效代码$post必须全球化，并在每次迭代时设置为正确的post对象，以及
setup_postdata() 用$post中的信息填充所有相关post变量。
此代码假定选项henrik_feat_pages 是帖子ID的有序列表。
Update 2
如何显示具有已知帖子ID的特定帖子，
$first_post_id 首先：
// Create ordered array of posts to show, with $first_post_id first
$posts_to_show = array_merge( (array) $first_post_id, (array) get_option( \'henrik_feat_pages\' ) );
// Get the pages whose IDs are in $posts_to_show
$posts = get_posts( array(
\'post_type\' => \'page\',
\'post__in\' => $posts_to_show
) );
// Create ordered post array:
$posts_by_id = array();
foreach( $posts as $post ) $posts_by_id[$post->ID] = $post;
// Output loop:
global $post;
foreach( $posts_to_show as $post_id ) {
$post = $posts_by_id[$post_id];
setup_postdata( $post )
// ... Template code as if you were in the loop.
}
注意，我在中简化了查询
get_posts() 所以只有
post_type 和
post__in 提供了参数。没有必要指定排序，因为这些帖子是按代码排序的。
