Question

我正在制作一个WordPress主题。我制作了如下所示的网格结构，

它包含两行，每行有三列。我想在此网格中显示我的WordPress数据库中的随机帖子。

这是我的代码

<div class="row">
  <div class="col-xs-12">
    <div class="rst-mediagrid">
      <div class="div">
        <?php
        $args = array(
          'posts_per_page'   => 6,
          'offset'           => 0,
          'category'         => '2',
          'category_name'    => '',
          'orderby'          => 'date',
          'include'          => '',
          'exclude'          => '',
          'meta_key'         => '',
          'meta_value'       => '',
          'post_type'        => 'post',
          'post_mime_type'   => '',
          'post_parent'      => '',
          'author'    => '',
          'post_status'      => 'publish',
          'suppress_filters' => true 
        );

        global $post;
        $post = get_post($args);

        $next_post = get_adjacent_post( true, '', false, 'taxonomy_slug' ); 
        ?>          
        <div class="rst-col rst-col-50">
          <div class="rst-postpic">
            <?php echo get_the_post_thumbnail($post->ID); //latest post thumbnail ?>
          </div>
        </div>
        <?php //endif; ?>

        <div class="rst-col rst-col-25">
          <div class="rst-postpic rst-postvideo">       
            <?php echo get_the_post_thumbnail($next_post->ID); ?>
          </div>
        </div>

        <div class="rst-col rst-col-25">
          <div class="rst-postpic">
            <?php echo get_the_post_thumbnail($next_post->ID); ?>
          </div>
        </div>

        <div class="clear"></div>
      </div>
      <div class="div">
        <div class="rst-col rst-col-25">
          <div class="rst-postpic">
            <?php echo get_the_post_thumbnail($next_post->ID); ?>
          </div>
        </div>
        <div class="rst-col rst-col-25">
          <div class="rst-postpic rst-postvideo">
            <?php echo get_the_post_thumbnail($next_post->ID); ?>
          </div>
        </div>
        <div class="rst-col rst-col-50">
          <div class="rst-postpic">
            <?php echo get_the_post_thumbnail($next_post->ID); ?>
          </div>
        </div>
        <div class="clear"></div>
      </div>
    </div>
  </div>
</div>

上面的代码重复了我要以完美的顺序显示缩略图的相同图像，例如第一行有三列，第一列有最新图像第二列有前一个帖子的图像，第三列有图像之前的平均值第3篇帖子来自最新帖子和第2行也有相同的内容。

如果你有更好的建议，请告诉我。

Answer 1

使用它不需要使用当前帖子的id作为参数。 <?php echo get_next_post(); ?>

Answer 2

最后我找到了我的问题的解决方案，如果其他人有相同的问题，那么使用这个

@Override
public List<User> searchUsers(String criteria, Car car) {
    //TODO: check params and return values based on test cases

    CriteriaBuilder builder = entityManager.getCriteriaBuilder();
    CriteriaQuery<User> query = builder.createQuery(User.class);
    Root<User> r = query.from(User.class);

    Predicate predicate = builder.conjunction();

    predicate = builder.or(predicate, builder.like(r.get("username"), "%" + criteria + "%"));
    predicate = builder.or(predicate, builder.like(r.get("firstName"), "%" + criteria + "%"));
    predicate = builder.or(predicate, builder.like(r.get("lastName"), "%" + criteria + "%"));
    predicate = builder.or(predicate, builder.like(r.get("nickname"), "%" + criteria + "%"));

    // how to implement the filter by foreign key value with AND? - can be a sub query to, which will be executed first time
    // I  need to use 1 Predicate, not a Predicate Array!
    query.select(r).where(predicate);

    List<User> result = entityManager.createQuery(query).getResultList();

如果有人有更好的建议，请在这里回答你的问题以及我的代码中的任何逻辑问题然后告诉我
