This is part 4 of the series. In this hands-on coding lab, you’ll build, test, and validate more advanced features for the data store, thereby extending its functionality and utility.
Let’s build, test, and validate the basics of the data store. In this hands-on coding lab, you’ll build the basic functionality and attributes of the data store in 3 different implementations: procedural, static class, and OOP. You’ll build a full test suite. And you’ll validate that the code complies to the WordPress Coding Standard.
Before we can build the data store, we need to understand what it is we need to build. In this lab, you’ll think through each of the requirements, working to define what makes a store a store, how to interact with it, what functionality is needed, and conceptually how to achieve it, and then what approaches you’ll employ in the series.
Let’s talk about the architecture and intent. While you could build a home.php or page_blog.php template, this plugin is portable and modular. It allows you to move it from project-to-project without having to change the theme. It uses the built-in WordPress editor, which your client is used to using. We are not using a widget because widgets are cumbersome for clients. A widget does not have the editor interface. It’s not as intuitive for the site owner to figure out where to put content when you use widgets instead of the page itself.
In today’s quality code tip, you will learn about removing the HTML from your business logic and putting it into a view file. In programming, you want to separate out your code by its intent and purpose. Let’s discuss the what, how, and why of view files. (Side note: I’m showing you the actual code on this website which is powered by Genesis.
Question: Which programming paradigm should I do? Answer: It doesn’t matter. Nope. You can program in any of these paradigms. What matters is you write clean, quality code and that you are proficient in one of these paradigms.
In this lab, you will build a custom WordPress Starter plugin, one which could be the starter for your projects. You’ll install Composer, Kint, and Whoops. You’ll look at file structure and how WordPress’ Plugin API recognizes which file is the plugin’s main file. You’ll look at PHP DocBlocks and more. This plugin is one you will use throughout your training here on Know the Code. Let’s get started.
