Rarst submitted a piece of code that allows you to display the number of Twitter followers you have.
In this article, we’ll show you how to display the number of Twitter followers in WordPress using a more advanced and attractive code. Rarst donated another another script to this project.
Features
This function is not restricted to the number of followers. Any non-nested value supplied by the Twitter users/show API call can be retrieved.
It has two cache levels:
- For $interval seconds, the query values are stored as an array in the database using WP options;
- API replies are cached in memory, allowing you to query any number of fields without having to make several API requests.
This should be safe to use for multiplying values and users at the same time without causing the API limit to be exceeded.
Tutorial
To begin, open the functions.php file in your theme and paste the following code:
