WordPress: how to separate comments and trackbacks

Today I read an interesting article on NETTUTS which claims to unravel the Secrets of WordPress & Comments.php File. This is actually pretty true, the author did a good job at explaining the different functions, comment loops, and form elements.

The one thing I really missed was an explanation on how to separate comments from trackbacks. Discussing on a blog with tons of trackback posts between the ongoing discussion is really annoying.

So here is my little addition to the NETTUTS tuorial:

How to separate comments from trackbacks in WordPress

First thing we need is a working peace of basic comment code, I’ll take the one from NETTUTS: (if you need any explanation on this piece of code, just read the aforementioned article)

<?php if($comments) : ?>
<ol>
    <?php foreach($comments as $comment) : ?>
        <li id="comment-<?php comment_ID(); ?>">
            <?php if ($comment->comment_approved == "0") : ?>
            <p>Your comment is awaiting approval</p>
        <?php endif; ?>
        <?php comment_text(); ?>
            <cite><?php comment_type(); ?> by <?php comment_author_link(); ?> on <?php comment_date(); ?> at <?php comment_time(); ?></cite>
        </li>
    <?php endforeach; ?>
</ol>
<?php else : ?>
    <p>No comments yet</p>
<?php endif; ?>

Now we will use the function get_comment_type(); to check which kind of comment this is. The function returns one of three possible values: pingback, trackback or a comment.
Our first target is to display only the comments. This is easily accomplished with an additional if statement:

<?php if($comments) : ?>
<ol>
    <?php foreach($comments as $comment) : ?>
       <?php if(get_comment_type() == "comment") : ?>
            <li id="comment-<?php comment_ID(); ?>">
                <?php if ($comment->comment_approved == "0") : ?>
                <p>Your comment is awaiting approval</p>
            <?php endif; ?>
            <?php comment_text(); ?>
                <cite><?php comment_type(); ?> by <?php comment_author_link(); ?> on <?php comment_date(); ?> at <?php comment_time(); ?></cite>
            </li>
        <?php endif; ?>
    <?php endforeach; ?>
</ol>
<?php else : ?>
    <p>No comments yet</p>
<?php endif; ?>

If you don’t want to display trackbacks you are done now. In case you want to show them, you have to call the comment loop a second time, this time only displaying the comment, if get_comment_type() returns pingback or trackback.

<?php if($comments) : ?>
<ol>
    <?php foreach($comments as $comment) : ?>
        <?php if((get_comment_type() == "pingback") || (get_comment_type() == "trackback")) : ?>
            <li id="comment-<?php comment_ID(); ?>">
                <?php comment_author_link() ?></li>
            </li>
        <?php endif; ?>
    <?php endforeach; ?>
</ol>
<?php endif; ?>

Thats it, not that hard to master and a big improvement in readability for your ongoing discussions.

    How to not display the second list (ol or ul) if there are no pingbacks ?

    I’m using a heading (h3 Trackbacks), like you do, but I don’t want that h3 to show when there are only comments.

    I tried to do an endif; after the comments, and then another if $comments before the trackbacks and it’s heading, but that if returns true (obviously), becuase the comment_type if-statment is within the foreach.

    So how can I do if (has_trackbacks()) ?
