Bit.ly is currently the most popular URL shorting service out there and for a good reason too. With bit.ly you can track your shortened URLs and much more. In this article I’m going to show you how to use bit.ly’s api create bit.ly urls automatically for WordPress posts.
In order to make use of Bit.ly’s API, you’ll need to:
- Signup at Bit.ly
- Get your API Key
Now that you have a login and API key, open your WordPress theme’s functions.php (just create one if you don’t have one) and paste the following code at the top of the document:
05 |
$url = get_permalink(); //generates wordpress' permalink |
06 |
$login = 'imjp'; //your bit.ly login |
07 |
$apikey = 'R_11882237eac772b5d6126e895a06c43f'; //bit.ly apikey |
08 |
$format = 'json'; //choose between json or xml |
15 |
//could also use cURL here |
16 |
$response = file_get_contents($bitly); |
18 |
//parse depending on desired format |
19 |
if(strtolower($format) == 'json') |
21 |
$json = @json_decode($response,true); |
22 |
echo $json['results'][$url]['shortUrl']; |
26 |
$xml = simplexml_load_string($response); |
The code above is pretty much self explanatory.
Don’t forget to change the login and apikey strings to match yours.
I’ve modified David Walsh’s “Create Bit.ly Short URLs Using PHP” in order to generate bit.ly urls automatically with WordPress. Now you can display your bit.ly url anywhere inside the loop or post .
The result of <?php bitly(); ?> in this post is http://bit.ly/4UbQ66.
