您需要执行wp\\u查询以将其他帖子类型输入到您的文件中，例如。

<?php
     $args = array(
      \'post_type\' => \'posttype_name\',
      \'posts_per_page\' => \'-1\',
      \'order\' => \'DESC\'
     );
     $query = new WP_Query($args);
     while ( $query->have_posts() ) {
      $query->the_post();
          the_title();
     }
     wp_reset_postdata();
     ?>

我知道了。。这是代码

<?php
                            $args=array(
    \'post_type\' => \'my_post_type\',
    \'post__not_in\' => array($post->ID),
    \'order\'=>\'ASC\',
    \'posts_per_page\'=> 3, // Number of related posts that will be shown.
    \'caller_get_posts\'=>1,
    );

    $loop = new WP_Query( $args );
    while ( $loop->have_posts() ) : $loop->the_post(); 
     the_title();
    the_content();
    endwhile;
    ?>
