So I have this shortcode that outputs a file I uploaded elsewhere on the internet.
It does so on every page load.
This means that the shortcode content isn't in the WordPress database.
How can I get shortcode output in the WordPress database?
It should refresh and check the external file periodically, to update the content in the WordPress database.
Currently I simple use (one line of code)
return '<div class="this">' . $stuff . '</div>';
I would like to know how I can make sure that this $stuff also gets into the WordPress library.
