An example of caching data using a WordPress transient

Caching WordPress data using Transients - Example

In this simple example we create a function for obtaining data from an external source and caching it for 24 hours. You can use the function hd_get_external_data() to get the data and work with it in your site.

If you want to force a refresh of the cache, you can pass a value of true into the function.

You can place the code into your themes functions.php file or better still in a plugin. If you are placing it in a plugin, remember to use function_exists() when using this. This ensures that the code will fail correctly if the plugin is not active.
