目前我所知道的最好的处理方法是Posts 2 Posts plugin:

• http://wordpress.org/extend/plugins/posts-to-posts/

这里有一个示例，展示了如何设置自定义帖子类型（如果您已经有了这些类型，那么阅读本文的其他人会受益匪浅）以及p2p_register_connection_type() 插件需要设置帖子关系。这可以放在你的主题中functions.php 文件或中的.PHP 您可能正在编写的插件的文件：

add_action(\'init\',\'event_performer_init\');
function event_performer_init() {
  register_post_type(\'event\',
    array(
      \'label\'           => \'Events\',
      \'public\'          => true,
      \'show_ui\'         => true,
      \'query_var\'       => \'event\',
      \'rewrite\'         => array(\'slug\' => \'events\'),
      \'hierarchical\'    => true,
      //\'supports\'      => array(\'title\',\'editor\',\'custom-fields\'),
    )
  );
  register_post_type(\'performer\',
    array(
      \'label\'           => \'Performers\',
      \'public\'          => true,
      \'show_ui\'         => true,
      \'query_var\'       => \'performer\',
      \'rewrite\'         => array(\'slug\' => \'performers\'),
      \'hierarchical\'    => true,
      //\'supports\'      => array(\'title\',\'editor\',\'custom-fields\'),
    )
  );
  if ( function_exists(\'p2p_register_connection_type\') )
    p2p_register_connection_type( \'event\', \'performer\' );

  global $wp_rewrite;
  $wp_rewrite->flush_rules(false);  // This only needs be done first time
}

然后在主题的模板文件中single-event.php 您可以添加如下代码来显示每个乐队的信息（我在这里展示了基本知识；我将留给您填写所有细节和/或在WordPress答案网站上询问其他更具体的问题，例如您是否需要知道如何获取特色图像等）

<?php
  if (count($performers = p2p_get_connected($post->ID))) {
    foreach($performers as $performer_id) {
      $performer = get_post($performer_id);
      echo \'The Band: \' . apply_filters(\'the_title\',$performer->post_title);
      echo \'Facebook Link: \' . get_post_meta($post->ID,\'facebook_link\',true);
    }
  }
?>
