Improving the Render

Let’s improve the render function, as we have too much going on in that function. We’ll abstract away the task of fetching the metadata from the database for our custom fields’ values. Why? Our render function’s job is to render the view. It needs the values, but does not need to know how to do it. Rather, just gimme the values for the custom fields.

We’ll also add a WordPress filter event to extend our meta data, allowing an external process to filter the values, do some processing, or just run before we render out to the browser.
