Question

我有一个循环，应该显示最近的博客文章。问题是posts_per_page仅显示一个帖子，而不显示三个帖子。我不知道哪里出了问题。

我尝试了以下步骤，但没有帮助，但对我没有用。

ignore_sticky_posts = > true, 
update_post_term_cache=>false, 
nopaging=>true

代码是：

<section class="ftco-section" id="blog-section">
  <div class="container">
    <div class="row justify-content-center mb-5 pb-5">
      <div class="col-md-7 heading-section text-center ftco-animate">
        <h1 class="big big-2">Blog</h1>
        <h2 class="mb-4">Our Blog</h2>
        <p>Far far away, behind the word mountains, far from the countries Vokalia and Consonantia</p>
      </div>
    </div>
    <div class="row d-flex">
    <?php if (have_posts()) :
    while (have_posts()) :the_post(); ?>
      <div class="col-md-4 d-flex ftco-animate">
        <div class="blog-entry justify-content-end">
          <a href="<?php the_permalink(); ?>" class="block-20" style="background-image: url('<?php echo get_the_post_thumbnail_url(get_the_ID()); ?>');">
          </a>
          <div class="text mt-3 float-right d-block">
            <div class="d-flex align-items-center mb-3 meta">
                <p class="mb-0">
                    <span class="mr-2">June 21, 2019</span>
                    <a href="#" class="mr-2">Admin</a>
                    <a href="#" class="meta-chat"><span class="icon-chat"></span> 3</a>
                </p>
            </div>
            <h3 class="heading"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
            <p><?php echo wp_trim_words(get_the_excerpt(), 30); ?></p>
          </div>
        </div>
      </div>
     <?php endwhile; ?>
     <?php endif; ?>
    </div>
  </div>
</section>

这是正确的循环方式吗？我遇到的问题是，现在我看不到任何博客文章。

根据我在代码中看到的内容，您正在while循环之外显示内容。另外，您正在将查询参数数组与$wp_query->query合并，但它们是不同的。您要使用：$wp_query->query_vars

在继续阅读之前，请确保您访问以下链接：

query_posts() documentation

The Loop documentation

您的代码应类似于：

<?php
global $wpdb;

$args = array(
  'post_type' => 'post',
  'orderby' => 'date',
  'order' => 'DESC',
  'posts_per_page' => 3,
);

$this_query = new WP_Query( $args );

?>

<section class="ftco-section" id="blog-section">
  <div class="container">
    <div class="row justify-content-center mb-5 pb-5">
      <div class="col-md-7 heading-section text-center ftco-animate">
        <h1 class="big big-2">Blog</h1>
        <h2 class="mb-4">Our Blog</h2>
        <p>Far far away, behind the word mountains, far from the countries Vokalia and Consonantia</p>
      </div>
    </div>
    <div class="row d-flex">
      <?php if ( $this_query->have_posts() ) : ?>
        <?php while ( $this_query->have_posts() ) : $this_query->the_post(); ?>
          <div class="col-md-4 d-flex ftco-animate">
            <div class="blog-entry justify-content-end">
              <a href="<?php the_permalink(); ?>" class="block-20" style="background-image: url('<?php echo get_the_post_thumbnail_url(get_the_ID()); ?>');">
              </a>
              <div class="text mt-3 float-right d-block">
                <div class="d-flex align-items-center mb-3 meta">
                    <p class="mb-0">
                        <span class="mr-2">June 21, 2019</span>
                        <a href="#" class="mr-2">Admin</a>
                        <a href="#" class="meta-chat"><span class="icon-chat"></span> 3</a>
                    </p>
                </div>
                <h3 class="heading"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
                <p><?php echo wp_trim_words(get_the_excerpt(), 30); ?></p>
              </div>
            </div>
          </div>
        <?php endwhile; 
        wp_reset_postdata();
      else : ?>
        <p><?php esc_html_e( 'Sorry, no posts found.' ); ?></p>
      <?php endif; ?>
    </div>
  </div>
</section>

posts_per_page仅显示1个帖子，而不是3个帖子
