Introducing Tweetbacks Plugin for WordPress


Just yesterday we introduced Twitter Avatars In Comments plugin for WordPress that enables bloggers to have both Twitter and Gravatar avatars in blog comments. We are certainly not going to turn Smashing Magazine into a repository of Twitter plugins for WordPress, but we are confident that it does make sense to introduce another plugin that enables another kind of Twitter integration in blogs.


This is why this post releases the Twittbacks WordPress Plugin that was developed and released especially for Smashing Magazine — this plugin imports tweets about your posts as comments. You can display them in between the other comments on your blog, or display them separately.

Advantages of our implementation Link

This implementation is inspired by Dan Zarrella’s great work on TweetBacks. Although his implementation does what it promises, we felt that it could be done in another way and offer users an alternative to display tweets in a more convenient way.

Dan’s solution uses JavaScript, which will work on more platforms, but we felt that it would be useful to actually store the tweets in the database instead of using JavaScript to display them. Because our implementation stores Tweets in the database, you can create new plugins that use this data on the top of our plugin.

Besides, our implemenation does not does not require JavaScript and requires significantly less time to load (server-side, not client-side). (Because we know you want to test this, and be able to ditch the plugin if you don’t like it, we’ve added an uninstall function, which will delete all the stored tweets from your WordPress database.)

Installation Link

The installation couldn’t be simpler:

  1. download the plugin from Joost de Valk’s release post,
  2. copy the “tweetbacks” folder to your plugin folder (wp_root/wp-content/plugins);
  3. login inside your WordPress administrator panel and activate this plugin (Click “Plugins” and then “Activate” near to the plugin title);
  4. if you are using WordPress 2.7, just add the code presented in the next section of this post (Styling and Adding Tweetbacks in WordPress 2.7) and you are done.
  5. otherwise if you are using older versions of WordPress, you can add Twitterbacks similarly to the way it is presented in this tutorial:
    1. Access your comments.php file and locate the following code:

      <?php foreach ($comments as $comment) : ?>

      Immediately after the above code, place this code:

        $comment_type = get_comment_type();
        if($comment_type == 'comment') {

    2. Next, scroll down a little bit and locate the following code:
      <?php endforeach; /* end for each comment */ ?>

      Put the following code right before the above code:

      <?php } /* End of is_comment statement */ ?>

      This will filter out all of the tweetbacks, trackbacks and pingbacks from your main comments loop. Now we need to create a second comments loop to display tweetbacks, and a third loop to display the trackbacks and pingbacks.

    3. Right under the code from step 2 you should find this code:

      <?php else : // this is displayed if there are no comments so far ?>

      Put the following code right before the above code:

      <?php foreach ($comments as $comment) : ?>
        <?php $comment_type = get_comment_type(); ?>
        <?php if($comment_type == 'tweetback') { ?>
          <li><?php comment_author_link() ?>: <?php comment_text() ?></li>
        <?php } ?>
      <?php endforeach; ?>

      Followed by this:

      <?php foreach ($comments as $comment) : ?>
        <?php $comment_type = get_comment_type(); ?>
        <?php if($comment_type != 'comment' && $comment_type != 'tweetback') { ?>
          <li><?php comment_author_link() ?></li>
        <?php } ?>
      <?php endforeach; ?>
    4. And you are done.

Styling and Adding Tweetbacks in WordPress 2.7 Link

As the plugin will import these tweets into your comments, they will by default be shown as normal comments on your blog. They will get the class tweetback. If you’re using WordPress 2.7 and the default theme, or any other theme that has taken the styling from the comments from the default theme (which is a sensible thing to do), you could style these tweetbacks by adding something like this to your stylesheet:

.commentlist li.tweetback {
  background-color: #94E4E8;

If you want to display them separately, you’ll have to separate your comments, pingbacks and tweetbacks from each other. A great tutorial on how to do that is Separating Pings from Comments in WordPress 2.7.

After you’ve done that, you can add the following code to display the tweetbacks:

if ( !empty($comments_by_type['tweetback']) ) :?>
  <h2 id="tweetbacks"><?php echo count($comments_by_type['tweetback']);?> Tweetbacks to &#8220;<?php the_title(); ?>&#8221;</h2>
  <ul class="commentslist tweets">
    <?php wp_list_comments('type=tweetback'); ?>

If you want to give that list of tweetbacks a different look and feel, you can add a callback to the wp_list_comments call above. The callback could make them look like this, for instance:

Separated Tweetbacks

The code for the callback used above looks like this:

function yoast_list_tweetbacks($comment, $args, $depth) {
  $GLOBALS['comment'] = $comment;
  $avatarurl = str_replace("twitter:","",$comment->comment_author_email);
  <li class="tweetback" id="comment-<?php comment_ID(); ?>">
    <div id="div-comment-<?php comment_ID(); ?>">
      <div class="comment-author vcard">
        <img alt='' src='<?php echo $avatarurl ?>' class='avatar avatar-40 photo avatar-default' height='40' width='40' />
        <cite class="fn"><a href="<?php echo $comment->comment_author_url; ?>" rel='external nofollow' class='url'><?php comment_author(); ?></a></cite> <span class="says">says:</span>
      <div class="comment-meta commentmetadata"><a href="#comment-<?php comment_ID(); ?>"><?php comment_date('F jS, Y'); ?> at <?php comment_date('H:i:s'); ?></a></div>
      <p><?php comment_text(); ?></p>
<?php }

Because these tweetbacks are stored as comments in your database, you can all sorts of cool things with them. Improving the Web has written a Widget pack that will work with this plugin, called Tweet Stats. It allows you to add widgets with “Recently tweeted posts” and “Most tweeted posts” (see examples below).

    Very useful little thing! Keep it up!


  10. 10

    Wait, how do other people going about a “Tweetback”? What does their twitter msg need in it?

  11. 11

    Awesome app, great job Dan! FYI, TweetBacks has a new logo; much nicer than the one in this post.

  12. 12

    Appears not to work with intensedebate. Am I right?

  13. 13

    Nathan, their tweet needs a link to the post in it, from a supported shorturl provider. The plugin currently supports tinyurl,,, snipr, snurl, snipurl,,adjix, advu & zima.

  14. 14

    Thanks… TwitterTools is out the window since it doesnt accounce new posts in a shortened url like tinyurl

  15. 15

    Thanks for all the kind words! Be sure to follow me on twitter to get the latest updates on the plugin!

    Another nice tweetback plugin … released yesterday ;)

    will be found under:

  18. 18

    Hmm…, have it installed but tweetback class isn’t showing up. Could be my theme maybe?

  19. 19

    Very nice plugin. Will for sure be using this sucker!

  20. 20

    this is a badass widget. instant classic.

  21. 21

    For everyone who has issues implementing the code for below 2.7 blogs: it should be == "tweetback", not = "tweetback", and for the trackbacks it should be != 'comment' && != 'tweetback' instead of just != 'comment'.

  22. 22

    Got this up and running on my blog. Is it possible to block your own Tweets from appearing in your Tweetbacks?

  23. 23

    Iain Broome not yet, but that’s a great idea!

  24. 24

    Oh yeah is looking good! Will put this up on my very first WordPress theme design on my website! Thanks for sharing! ;)

  25. 25

    Works wonderfully – thanks Joost :D

    @Joost de Valk (#19): thanks, the post was updated.

  27. 27

    Can´t make it work with the Revolution theme. I can se that somebody has tweeted in the sidebar for the widget latest comments. I can see that there has been a comment (tweet) left in the commentsection, but I cant´t see the comment (tweet) itself.

    What to do?

  28. 28

    Would like to thank Joost as he helped me get things rocking nicely with this plugin at my site ( Really a great tool, lots of potential.

  29. 29

    Nice. I will be adding this into my sites over the next couple days. Thank you for releasing this.

  30. 30

    very nice i’ll add to my blog.
