I would like to change the commenter links as shown in this screenshot:


In my test plugin at GitHub I have first tried the following code:

define('PROFILE', '<a href="/user/%s" rel="external nofollow" class="url">%s</a>');

function get_comment_author_link($cid) {
   $uid = get_comment_author($cid);
   return sprintf(PROFILE, $uid->ID, $uid->name);

add_action('get_comment_author_link',  'get_comment_author_link');

But then by studying the file wp-includes/comment-template.php I have realized, that the argument to get_comment_author_link is not a comment ID, but a string containing <a href="...">...</a> and thus I can't use this hook for my purpose (because the user ID can't be found in the hook).

Please advise me a suitable hook or way to change the commenter links.

You can use the get_comment_author_link hook, which is part of the get_comment_author_link() template tag, like your question already suggests. Then you only have to get the according user_id, which can be done via the $comment global, and construct the link you want accordingly.

Exemplary usage like shown below:

add_filter( 'get_comment_author_link', 'wpse144835_custom_comment_author_link' );
function wpse144835_custom_comment_author_link( $link ) {
    global $comment;
    $comment_user_id = $comment->user_id;
    // code to create the new link
    return $new_link;


Responding regarding your questions, the according comment is unfortunately deleted, so this is kind of a informational shortlist now. There is a lot in there, way too much to really answer them, but I give you some additional information:

    Thanks for the references! (Sorry, I've occasionally deleted my old comment - after I've found $comment->comment_author). I will gladly award the bounty in a day. May 22, 2014 at 18:33

    Ohh, sure, how could I've forgot about that! @AlexanderFarber May 22, 2014 at 18:35
  • Could you please take 1 more look at my site slova.de/archives/29 - both the users "Mr. WordPress" and the user "aaa" (someone registered at my site) have the /user/0. Why do they both have their ID == 0? May 22, 2014 at 18:45

    0 means that it is a comment by unregistered user; the user mr. wordpress doesn't exist, so it's a unregistered comment, what about your aaa user? @AlexanderFarber May 22, 2014 at 18:56

    Not a problem, I'm still learning every day. It depends on your setup under Settings > Discussion. If you want unregistered comments you probably should implement a condition for that, because the profile page only will only work for registered users. @AlexanderFarber May 22, 2014 at 19:13

The output of that function, is an a-tag containing a link to the author profile, its input is definitely an ID.

If you'd like to change the output of that function, you need a filter and you'd need to str_replace the a-tag (or similar method acting on the string). (see where to modify get_comment_author_link()?)

I think the more important question is: what exactly are you trying to achieve here?

In theory the commenters link could be implemented differently in every theme/plugin. It could be done with get_comment_author_url() or retrieved straight from the comment object with get_comment(), or any other way really.

However to alter the output of get_comment_author_link(), see the example above.


Could you try:

 $id = get_comment( get_comment_ID() )->user_id;

I just found this solution while googling, but I don't have an environment to test it out.

    This should work, but there are unnecessary steps in it. May 22, 2014 at 17:32
