add rel=“nofollow” to comment_metadata

Question

how can i add rel="nofollow" to link that have time tag, inside the comment-metadata div?

<div class="comment-metadata">
<a href="http://localhost/wordpress/hello-world/#comment-2">
<time datetime="2013-12-22T10:43:03+00:00">...</time>
</a>
</div>


  function add_nofollow_to_comment_metadata( $link ) {
      return str_replace( '")\'>', '")\' rel=\'nofollow\'>', $link );
  }

  add_filter( 'comment_comment_metadata', 'add_nofollow_to_comment_metadata' );

i use <?php wp_list_comments(); ?> <?php wp_list_comments(); ?> without any customise.

Answer 1

There is no way to modify this behavior via hooks or filters. But you can implement this by:

1. Using get_comments function. It allows maximum customization.
2. Extending Walker_Comment class and implementing your custom functionality.

The first option is obviously simpler.

Answer 2

您不需要添加代码WordPress会自动nofollow评论链接
