Theming comments by the node's author

You want the comment style to be different for comments added by the author of a node — who's commenting on his own node. For example, you may want to highlight the node's author's comments, so that any visitor skimming through the comments will easily differentiate them from other comments.

Solution

  1. Edit comment.tpl.php to add a new class (let's say 'comment-by-author-of-post') that...

  2. you can style in your theme's style.css.

Your file comment.tpl.php may look like this before the edit (I am only providing a snippet of the template here):

<div class="comment<?php print ($comment->new) ? ' comment-new' : ''; print ' '. $status ?> clear-block">

If it does, then you will change the above snippet to that:

<div class="comment<?php print ($comment->new) ? ' comment-new' : ''; print ($comment->uid == $node->uid) ? ' comment-by-author-of-post' : ''; print ' '. $status ?> clear-block">

You could now add these two rules to your style.css file, for example:

/**
 * Comment styling rules
 */
.comment-by-author-of-post {
  border: 1px solid #ccc;
  background-color: #eee; 
}
/* reset to default values when previewing */
.preview .comment-by-author-of-post {
  border: none;
  background-color: transparent;
}

This will work in Drupal 5 as well. No, it won't. The $node object is not passed to the comment.tpl.php template. Read the comments below for the Drupal 5 recipe. This solution works only for PHPTemplate-powered themes. If your theme does not provide a template file for comments, copy the one from modules/comment/ to your theme folder, and edit it. And yes, the $node object is available in comment.tpl.php. It is the node the comment is attached to. Possible variations: special-style all comments authored by those who have the 'admin' role; special-style anonymously-submitted comments; etc.

We used a Ternary Comparison Operator in our solution.

($a == 11) ? 'eleven' : 'not eleven'

The above code snippet returns a value. If $a equals 11, the return value is 'eleven'; otherwise, the return value is 'not eleven'. You can print the return value of a ternary comparison operator like so:

print ($a == 11) ? 'eleven' : 'not eleven';

Notice that I added both 'print' and a semicolon in the above snippet.

From php.net: “The expression (expr1) ? (expr2) : (expr3) evaluates to expr2 if expr1 evaluates to TRUE, and expr3 if expr1 evaluates to FALSE.” The ternary comparison operator is used a lot in Drupal templates. In our solution we printed ' comment-by-author-of-post' — in the class attribute of the comment div — if and only if the comment author was the same guy/girl as the author of the node the comment was attached to. And we printed nothing otherwise, ie: ''. (These '' are two SINGLE quotes.) We added this:

<?php print ($comment->uid == $node->uid) ? ' comment-by-author-of-post' : ''; ?>

Drupal 5?

I am sorry, but this one seems not working with Drupal 5? The snippets from the template for Drupal 5 is supposed to be this one:

status == COMMENT_NOT_PUBLISHED) print ' comment-unpublished'; ?> ">

And I've changed it to:

status == COMMENT_NOT_PUBLISHED) print ' comment-unpublished'; print ($comment->new) ? ' comment-new' : ''; print ($comment->uid == $node->uid) ? ' comment-by-author-of-post' : ''; print ' '. $status ?> ">

But it's still not working. Any help?

Thanks for the attention. :)

In Drupal 5, no $node object in comment.tpl.php

What you do have is the nid of the node the comment is attached to.

So what you need to do is pass the node's author uid, along to comment.tpl.php.

Something like this needs to be done in the file template.php of your theme:

function _phptemplate_variables($hook, $vars = array()) {
  switch ($hook) {
    case 'comment':
      // The following will require no database query,
      // because the node is in the cache
      $node = node_load($vars['comment']->nid);
      $vars['node_uid'] = $node->uid;
      break;
  }
  return $vars;
}

Then you can use $node_uid in comment.tpl.php — that'll be the uid of the node author.

<div class="comment<?php if ($comment->status == COMMENT_NOT_PUBLISHED) print ' comment-unpublished';  print ($comment->new) ? ' comment-new' : ''; print ($comment->uid == $node_uid) ? ' comment-by-author-of-post' : ''; print ' '. $status; ?>">

Just one author?

Just one blogger on your web site? Do not bother with checking who is the author of the node. Do not bother with passing an additional variable to your comment template.

In the case where you have only one blogger... you could do as I do here (and yes, my web site still runs on Drupal 5...). Using a hard-coded value for the author of the node, eg: 1 (the Administrator of the site):

<div class="comment<?php print ($comment->uid == 1) ? ' comment-by-author-of-post' : ''; print ($comment->new) ? ' comment-new' : ''; print ($comment->status == COMMENT_NOT_PUBLISHED) ? ' comment-unpublished' : ''; print ' '. $zebra; ?>">

Thanks

Sorry for my noobness, but thanks! It works wonderfully on my site. Thanks, once again.

Which Drupal version does this work for?

Hi guys,
Just reading the comments, what version of Drupal does the above example work for? I read issues with Drupal 5 so does this mean its a Drupal 6 solution? Or is it Druapl 4?

I'm looking for the Drupal 6 solution.

Cheers,
Gavin.

PS: What WSYIWIG are you using with Drupal?

Hi Gavin

what version of Drupal does the above example work for?

Drupal 6.

What WSYIWIG are you using with Drupal?

None. I use BUEditor. It's not WSYIWIG per say, although it's an editor and has a really nice ajaxified preview button. I loooove it: http://drupal.org/project/bueditor.

Ah, finally. I was wondering

Great information

As a noob and has no knowledge in php programming, this infomation can greatly teach me on how to do hard things easy.

Theme coding for authors/admins

Edited the comment.tpl.php and added the two rules to the css file and it worked like a charm. Thanks Caroline, for providing the code, I was spending a lot of time searching Google and couldn't find anything on how to change the admin highlighting style to distinguish them from regular users until I found this post.

Good idea and detailed instructions!

It would be prudent to synchronize and back-up all your hard work with a service that provides online backup.

Thank you.

I was stuck in the middle

I was stuck in the middle while trying it in my Joomla 1.5 site. The border is solid here but by default I have a nice border from the template maker though the solid code didn't worked as I applied that.

nice post.

Will try to use this today and see how it goes..

That was new blog i never

That was new blog i never thought of that. Many interesting blog that you brought to us is about the a centering point of component parts of the author which bring me for applying it i needed. So for now i say it is good and all i wanted to know from your blog the answer of my question.

Simply wish to say thanks.

Simply wish to say your article is as astonishing. The clarity in your post is just cool and i could assume you are an expert on this subject. Well with your permission allow me to grab your feed to keep up to date with forthcoming post. Thanks a million and please keep up the gratifying work.
