How To Render Your Twitter Followers Count In Your WordPress Blog

Adding the following snippet to your theme’s functions.php file, you will be able to render your Twitter followers count. Also, remember to replace “planetabhi” with your own Twitter screen name.

function my_followers_count($screen_name = 'planetabhi'){
	$key = 'my_followers_count_' . $screen_name;
 
	// Let's see if we have a cached version
	$followers_count = get_transient($key);
	if ($followers_count !== false)
		return $followers_count;
	else
	{
		// If there's no cached version we ask Twitter
		$response = wp_remote_get("http://api.twitter.com/1/users/show.json?screen_name={$screen_name}");
		if (is_wp_error($response))
		{
			// In case Twitter is down we return the last successful count
			return get_option($key);
		}
		else
		{
			// If everything's okay, parse the body and json_decode it
			$json = json_decode(wp_remote_retrieve_body($response));
			$count = $json->followers_count;
 
			// Store the result in a transient, expires after 1 day
			// Also store it as the last successful using update_option
			set_transient($key, $count, 60*60*24);
			update_option($key, $count);
			return $count;
		}
	}
} 
echo "I have " . my_followers_count('planetabhi') . " followers";

function my_followers_count($screen_name = 'planetabhi'){

$key = 'my_followers_count_' . $screen_name;

// Let's see if we have a cached version

$followers_count = get_transient($key);

if ($followers_count !== false)

return $followers_count;

else

{

// If there's no cached version we ask Twitter

$response = wp_remote_get("http://api.twitter.com/1/users/show.json?screen_name={$screen_name}");

}

set_transient($key, $count, 60*60*24);

update_option($key, $count);
