Putting it All Together

As I told you before, the key is to read code. The more code that you read, the more you’ll learn and grow. The skills you gained in this lab empowered you to be able read the basic structure of themes and plugins. No, you might not be able to understand all of the code. But you can see the patterns.

You’ll see the functions and know the basics of how they are defined and called. You’ll know that some can accept information to work on while others don’t need anything. You’ll see default parameters defined and know how that works.

When you come to decision-based code, you’ll know that the code block only runs if the decision is true.

You’ll recognize more quickly when you get a syntax parsing error, as we went over the basics.

You learned that variables have scope and that means functions can only talk with their variables. You know how to bring a global variable into a function.

You know that variables are placeholders to represent some information. You know how to assign a value to a variable.

Let’s read some code together. You and I will read through the Genesis Sample theme and the Twenty Seventeen theme together.

WordPress is built on an event-driven engine. Through the Plugin API, we developers are given the power to extend, reorder, remove, and change the behavior of WordPress, plugins, and themes. Success in WordPress begins right here with a solid fundamental mastery of the event-driven system. As a professional developer, it is essential that you master the event-driven (hook) system in WordPress. It's at the center of everything we do, allowing us to interact with or hook into each other's products using functions such as add_action and add_filter.
