Bricks Builder / MetaBox / ACF Live update options
This video shows a way to create a Settings/Options page with MetaBox or ACF and have the values live update for all viewers currently viewing a page, in near real-time.
NOTE: This uses a rudimentary Polling method. There are modern methods to push data to browsers using websockets. For very high traffic websites, that would be much better. However, for this demo I wanted to keep it simple so that anyone can do it directly from WordPress and a code manager.
You will learn:
How to create simple Settings / Options pages
How to prepare Elements for live updating
How to create a simple WordPress REST endpoint
How to use JavaScript to get the data for the REST endpoint and update the elements.
