Before you begin, make sure that you have the code from the Introduction to PHP Object-Oriented Programming (OOP) for WordPress lab. If you do not have that code, no problem, as you can get it from this GitHub repository.
Let’s talk about the WordPress event-driven system. Then you’ll look at the code in WordPress Core to use how it’s using the PHP construct
call_user_func_array in order to call each of the pre-registered callbacks when the event is fired.
It’s important to have a basic understanding of hooks, which are events and why they exist. In this episode, you’ll get a brief review. Make sure you watch it.
Then we’ll discuss what you’ll be doing in this lab.
If you need a refresher, then make sure you take this lab:
You can also find information on the following WordPress Core constructs in Docx:
Who needs copy/paste? Right. Writing code from scratch is fun!
