FeedBurner subscription show-off revisited

Joost de Valk — Sun, 21 Dec 2008 19:08:00 +0000

A couple of months back I blogged about how to show off your FeedBurner subscribers. In the comments then, a couple of people told me the code didn't work for them. After a few back and forths I found out those people were on FeedBurner's new servers, the Google ones.

This new server actually has a new API Endpoint as well, and this endpoint brings along a bit of trouble. Google in all its wisdom decided to move the API onto HTTPS. Problem is, I was using Snoopy, which rocks, but doesn't work with HTTPS easily. It needs CURL for that, and if it needs CURL anyway, why not use the built-in PHP CURL. So, here's the code to use when you're on feedproxy (if this doesn't work for you, try the above linked older code):

$url	= "https://feedburner.google.com/api/awareness/1.0/GetFeedData?uri=joostdevalk";
$ch 	= curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
$data = curl_exec($ch); 
curl_close($ch);		
if ($data) {
	preg_match('/circulation=\"([0-9]+)\"/',$data, $matches);
	if ($matches[1] != 0)
		$fb['count'] = $matches[1];
	$fb['lastcheck'] = mktime();
	update_option("feedburnersubscribecount",$fb);
}
echo $fb['count'].' Subscribers can\'t be wrong! Subscribe by <a href="http://yoast.com/email-blog-updates/">emaila> or to the <a rel="nofollow" href="http://feeds.feedburner.com/joostdevalk">RSS feeda> now!';

Enjoy!

Showing off your FeedBurner subscribers

Quite a few websites have started to show of their FeedBurner subscriber count with something else than a widget. To do that, you have to be able to grab the number of subscribers through the FeedBurner API.

Now I bet you want to know how! It's bloody easy in WordPress, just do this:

$fb = get_option("feedburnersubscribecount");
if ($fb['lastcheck'] < ( mktime() - 600 ) ) {
	$snoopy = new Snoopy;
	$result = $snoopy->fetch("http://api.feedburner.com/awareness/1.0/GetFeedData?uri=feedburnerid");
	if ($result) {
		preg_match('/circulation=\"([0-9]+)\"/',$snoopy->results, $matches);
		if ($matches[1] != 0)
			$fb['count'] = $matches[1];
		$fb['lastcheck'] = mktime();
		update_option("feedburnersubscribecount",$fb);
	}
}
echo ''.$fb['count'].' Subscribers can\'t be wrong! Subscribe by <a href="http://yoast.com/email-blog-updates/">emaila> or to the <a rel="nofollow" href="http://feeds.feedburner.com/joostdevalk">RSS feeda> now!';

Copy, paste, replace feedburnerid with your own FeedBurner ID, and you're done!

Update: updated the code to include caching, as you might overload the FeedBurner API otherwise.

Update 2: if you get an error saying it can't find the class Snoopy, add this above the code:

require_once(ABSPATH . 'wp-includes/class-snoopy.php');

If this doesn't work for you, and you're on FeedBurners new feedproxy.google.com servers, try this solution.
