I noticed that the Grunge template doesn't include formatting specific to pingback comments. As a result, a pingback comment left on a post will look quite large and cluttered due to it being formatted as a regular comment. So, I edited rt_grunge_wp/html/layouts/comment_basic.php to include pingback specific formatting.
Just below:<div class="comment-author vcard" style="line-height: 50px;">
I added this:<?php $ispingb = false; if($comment->comment_type == 'pingback') { $ispingb = true; } ?>
<?php if($ispingb) { echo '<div class="pbcomment">'; printf(_r('<cite class="fn">%s</cite>'), get_comment_author_link()); printf(edit_comment_link(_r('(Edit)'))); echo '</div></div>';} else { ?>
And just above<?php echo ob_get_clean(); return;
I added this:
I'm sure there is a better and more efficient way to do it, but this is how I figured it out using my limited PHP knowledge. Then I used CSS to style the pingback to my desire using .pbcomment. Just thought I would post this in case anyone else was trying to figure it out.
