Tweetmeme is a Digg-like site for popular links on Twitter. Using a Tweetmeme badge can be a helpful reminder for your readers to retweet it – and if my experience is anything to go by, Twitter does send targeted traffic to your blogs. Clicking on the Tweetmeme badge will direct you to your Twitter profile, with a tweet of the format RT @tweetmeme <post title> <post link>.
PHP function to to display Tweetmeme badge
Since you would want to show the Tweetmeme badge on multiple pages (on single.php, index.php etc.), wrapping the code in a simple function is a good idea. We can then call this function wherever we want the badge to be displayed.
Open up your theme’s functions.php file. At the end of the file, you will find a
Place the code below just before that.
PHP tag to display the badge
In single.php and index.php, place the code below just before the tag <?php the_content(); ?> or <?php the_excerpt(); ?>.
<?php $check_sm = get_post_meta($post->ID, 'tweetmeme', $single = true); if($check_sm != '') tweetmeme(); ?>
Enabling the badge on posts
Enabling the Tweetmeme badge requires you to add a custom field to the post in question. On posts where you want to display the post, add a field named tweetmeme with a value true.
You can also extend this hack to hide Tweetmeme badge only on posts where you enter a custom field, or show other badges (Digg, Stumble Upon etc.) selectively.
