Separate WordPress Comments and Trackbacks

1 ) Access your comments.php file and locate the following code:
 
<?php foreach ($comments as $comment) : ?>
 
Immediately after the above code, you'll want to place this code:
 
<?php $comment_type = get_comment_type(); ?>
<?php if($comment_type == 'comment') { ?>
 
2 ) Next, you'll want to scroll down a little bit and locate the following code:
 
<?php endforeach; /* end for each comment */ ?>
 
Immediately before the above code, you'll want to place this code:
 
<?php } /* End of is_comment statement */ ?>
 
This will filter out all of the trackbacks and pingbacks from your main comments loop. Now we need to create a second comments loop to display the trackbacks and pingbacks.
 
3 ) Almost immediately below the code from step 2 you should find this code:
 
<?php else : // this is displayed if there are no comments so far ?>
 
Immediately before the above code, you'll want to place this code:
 
<h3>Trackbacks</h3>
<ol>
<?php foreach ($comments as $comment) : ?>
<?php $comment_type = get_comment_type(); ?>
<?php if($comment_type != 'comment') { ?>
<li><?php comment_author_link() ?></li>
<?php } ?>
<?php endforeach; ?>
</ol>
