您可以使用get_adjacent_post 用于检索该数据的函数。此函数用于检索相邻立柱。可以是下一篇文章，也可以是上一篇文章。

For previous post

<?php

  $prevpost = get_adjacent_post( false, \'\', true, \'category\' );

  $image = get_the_post_thumbnail( $prevpost );
  $name = get_the_title( $prevpost );
  $url = get_permalink( $prevpost );

?>

For next post

<?php

  $nextpost = get_adjacent_post( false, \'\', false, \'category\' );

  $image = get_the_post_thumbnail( $nextpost );
  $name = get_the_title( $nextpost );
  $url = get_permalink( $nextpost );

?>
