wordpress同一页面上的两个自定义循环？

Question

我在这里找不到任何东西，所以我把这个问题带给你。下面的代码主要做我想要的，只有页面循环不起作用：当我想导航到旧帖子时，看到的页面再次显示相同的新帖子。我该如何正确地做到这一点？

所以 index.php 有两个循环：

<?php
  $args = array( 'numberposts' => 1, 
    'post_status'=>"publish",
    'post_type'=>"post",
    'orderby'=>"post_date");
  $postslist = get_posts( $args );
  foreach ($postslist as $post) :  setup_postdata($post); 
?>

  // regular post html with wp tags

<?php endforeach; ?>

<?php
  query_posts('posts_per_page=12&offset=1');
  if (have_posts()) : ?>

<h3>Headline</h3>

<?php while (have_posts()) : the_post(); ?>

  // regular html with wp tags for these posts (teasers, with the_excerpt)

  <?php endwhile; ?>

    <div class="navigation">
      <span class="nextlink"><?php next_posts_link( 'Older', 0 ); ?></span>
      <span class="previouslink"><?php previous_posts_link( 'Newer' ); ?></span>
    </div>

    <?php else : ?>

    <h3><?php _e('Nothing found'); ?></h3>

  <?php endif; ?>

解释如下： 一个人访问博客：最新的博文在一个区块中全长显示，12 篇较旧的博文（不包括第一个带有offset 的博文，所以 2-13）在另一个区块中显示块与内容预告片和底部的下一个上一个导航显示帖子预告片 14-25 等等。 （问题：总是2-13）

// 编辑：响应顶部答案的代码，现在是 index.php 的完整代码。请注意，HTML 已更改，因为我使用了规范化的 HTML，因为它通常无关紧要。这次是实际代码。

<?php get_header(); ?>

<div class="box blog-block">
  <?php
    $args = array( 'numberposts' => 1, 'post_status'=>"publish",'post_type'=>"post",'orderby'=>"post_date");

     foreach ($postslist as $post) :  setup_postdata($post); ?>

我现在正在试用此代码（14.10.17），但它没有添加功能页面导航...：

<?php get_header(); ?>

<div class="box blog-block">
  <?php
    $args = array( 'numberposts' => 1, 'post_status'=>"publish",'post_type'=>"post",'orderby'=>"post_date");
    $postslist = get_posts( $args );
     foreach ($postslist as $post) :  setup_postdata($post); ?>
  <span class="head"><?php the_time('j. F Y') ?></span>
  <h3><a href="<?php the_permalink(); ?>" title="<?php the_title();?>"><?php the_title(); ?></a></h3>
  <div class="entry">
    <?php global $more;
          $more = 1;
          the_content();
    ?>
    <p class="author"><?php the_author(); ?></p>
    <p><a class="more-link" href="<?php the_permalink(); ?>#respond" title="<?php the_title();?>">Kommentieren</a>
  </div>

    <?php endforeach;
    wp_reset_postdata(); /* 1. reset post data */
    ?>

Answer 1

您尚未设置分页，因此您的查询始终认为它在第 1 页。

另外根据 WP Developer Resources ，您不应该使用 query_posts - 使用 WP_Query 或 pre_get_posts 代替，所以我使用下面的 WP_Query 来进行第二次查询。

请注意，我假设您在静态主页上使用它，但我已在 cmets 中添加了自定义页面所需的更改。

<?php
  $args = array( 'numberposts' => 1, 
    'post_status'=>"publish",
    'post_type'=>"post",
    'orderby'=>"post_date");
  $postslist = get_posts( $args );
  foreach ($postslist as $post) :  setup_postdata($post); 
?>

  // regular post html with wp tags

<?php endforeach; 
wp_reset_postdata(); /* 1. reset post data */
?>

<?php
/* Set up your pagination - $paged will contain the current page, telling WP_Query which post to start with (e.g. #13 on page 2) */
$paged = ( get_query_var('page') ) ? get_query_var('page') : 1;

/*  NOTE: if this is NOT on a static page
get the 'paged' query var instead of 'page', i.e.:
$paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
*/

$display_count = 12; /* variable for the number of posts per page */
$excluded_count = 1; /* the number of posts excluded from the start position */

/* Calculate the offset, i.e. the post number to start the page with
   Normally this is calculated by: ($paged-1) * $display_count 
   so we just need to add 1 for the one we excluded */
$offset = ( ($paged-1) * $display_count ) + $excluded_count;

/* set up your new query passing in the page so WP_Query knows what to return */
$args = array(
    'post_status'=>"publish",
    'post_type'=>"post",
    'orderby'=>"post_date",
    'posts_per_page' => $display_count,
    'offset' => $offset,
    'paged' => $paged
);

/* set up your new query */
$the_query = new WP_Query( $args );
<?php if ( $the_query->have_posts() ) : ?>

    <h3>Headline</h3>

    <?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>    

        // regular html with wp tags for these posts (teasers, with the_excerpt)

    <?php endwhile; ?>

    <div class="navigation">
      <span class="nextlink"><?php next_posts_link( 'Older', $the_query->max_num_pages ); ?></span>
      <span class="previouslink"><?php previous_posts_link( 'Newer' ); ?></span>
    </div>

    <?php else : ?>

    <h3><?php _e('Nothing found'); ?></h3>

<?php endif; ?>

以上代码未经测试，但基本逻辑应该是对的。

更新：

next_posts_link 和 previous_posts_link 默认使用全局变量$wp_query，所以要使用自定义查询，将$custom_query->max_num_pages 传递给next_posts_link，例如：

<span class="nextlink"><?php next_posts_link( 'Older', $the_query->max_num_pages ); ?></span>
<span class="previouslink"><?php previous_posts_link( 'Newer' ); ?></span>
