Say you wanted to create a shortcode like this: [youtube id="991WcoEPwb8"]
And instead of manually creating the HTML yourself, you wanted to use YouTube’s oEmbed provider to get the HTML. While that’s easy to do using WordPress’ existing functions (wp_oembed_get() for example), you must implement your own caching of the result as WordPress’ oEmbed class does not include any caching of it’s own.
However, WordPress comes with an [embed] shortcode that’s also secretly used for the shortcode-less embeds. A cool trick is to make that shortcode’s existing code (complete with caching) work for you! This post explains how to do it.
