Labs

Labs are hands-on coding projects that you build along with Tonya as she explains the code, concepts, and thought processes behind it. You can use the labs to further your code knowledge or to use right in your projects. Each lab ties into the Docx to ensure you have the information you need.

Each lab is designed to further your understanding and mastery of code. You learn more about how to think about its construction, quality, maintainability, programmatic and logical thought, and problem-solving. While you may be building a specific thing, Tonya presents the why of it to make it adaptable far beyond that specific implementation, thereby giving you the means to make it your own, in any context.

Configuration in ModularConfiguration Architecture

Let’s talk about the “configuration” part of ModularConfig. How do you design your code to be configurable? What does it mean? Why would you want to? Our codebase is filled with hard-coded parameters that specify the implementation we want. For example, registering a custom post type requires: Labels Supported features Arguments Post type name Imagine that your project has more than one custom post type. For example, let’s say you’re building a business-centric website and the client wants: FAQ Portfolio Testimonials Team bios That means, your project has at least four new post types. Think about that. Imagine what your […]

Modular in ModularConfiguration Architecture

Let’s talk about what the modular part of ModularConfig is. How do you design your code to be modular? What does it mean? The de facto in WordPress is to use snippets and boilerplates. This lab introduces you to the modular approach. Boilerplates give you a code structure or template. Then you edit the code to change the implementation. You may go to a website, fill out a form, and then that site automatically edits the code’s boilerplate to change it for you out of convenience. But the code is being changed to fit your project’s implementation. Snippets are tiny […]

What is Reusable?

What does reusable mean to you? Why would you want to use it? In software, the concept of being “reusable” means that you design your code such that you can reuse it project-after-project with minimal to no rework of the code. Think about that. Imagine the time you’ll save when you have a library of pre-built, well-tested, and proven code modules. You can then load the modules and quickly build your projects. But the key is: minimal to no rework of the code. That is what makes it reusable. Why? Think about it. If you pull in a snippet of […]

Lab Introduction

In this lab, you will learn about how to make your code reusable. You’ll learn about what it is, why you want to change your mindset to build code in a reusable way, and then how to do it. You are a professional web developer. It’s your career and/or business. You need to make money. Designing your code to be reusable is a strategy to reduce your time and thus costs over the entire lifecycle of the code itself. In other words, it makes you more profitable. To get started, make sure that you have completed Part 1 and 2 […]

WordPress Built-in User Metadata Basics

Out-of-the-box, WordPress gives us built-in user metadata, which captures details about each user. We use this metadata to personalize the user’s experience as well as for processing and filtering tasks, such as checking access rights, capabilities, and more. In this hands-on lab, you will learn the basics of WordPress user metadata, the database, and the profile interface in the back-end.

Coming Soon

WordPress Term Metadata Basics

Using term metadata, we can add additional information to terms. We use this information for specific filtering, querying, grouping, and processing tasks. In the back end, we build metaboxes provide an interface for authors to input the details for the term metadata. In this hands-on lab, you will learn the basics of WordPress term metadata, metaboxes, and custom fields you build for their interface.

“Object Not Available” Strategies

There are times when you can’t get a hold of the object in order to remove a method callback from that object. The author wrote it such that s/he did not expose the object for you. What do you do? How can you get that object in order to do your work and unregister its callback? Here are strategies in order: Talk to the author and see s/he will add a filter or action to pass the object to you. If it’s open source, submit a pull request to add the filter/action code. Evaluate if you have to use this […]

Wrap it Up

Let’s review what you learned in this lab about registering and unregistering callbacks for both static and object methods. You looked into WordPress Core and saw that it is using call_user_func_array to call each of the registered callbacks for a given event hook. You learned strategies for working with 3rd party code including WooCommerce. If the WordPress Event registrations confused you, go take this lab. Congratulations for completing this lab!

Design Strategy

When you are registering and unregistering callbacks within an object, you typically do this task as part of the object’s initialization process. Instead of putting all of the init tasks into the constructor, break it out. Put the callback registration into a separate method called init_events().

3rd Party Static Callbacks

There will be projects where you need to remove a static method’s callback from a 3rd party plugin. How do you find and remove it? You should never edit their code. Why? Because when they do updates, your changes will be overwritten. Instead, you need to find where the callback is registered, i.e. with a add_action or add_filter. Then, you need the class name. Lastly, you have to figure out the timing of when the callback is registered. Why? Because you can’t unregister it until it’s been registered. Doing it too early is a timing mistake and will cause wonky […]
