Adding an author byline to the posts

Hi,

I’ve got my site almost to the point I want it. I created this code to allow for Google + crawling of my multiple bloggers, and I put it in the content.php file.

<p class="vcard author"><span class="fn">
      <?php $getid = $posts[0]->post_author; if($getid == 1){ ?>
      <?php } else { ?>
      by
      <?php the_author(); ?>
      <?php } ?></span>
<span class="updated"><?php the_time(get_option("date_format")); ?></span>
</p>

Unfortunately, this is pushing down the content on my pages in addition to the post pages, which I don’t want. Since Esquire doesn’t have a single.php file, has anyone figured out a good way to give author credit to posts without effecting other pages?
