Out-of-the-box, WordPress does not provide the editor or a means to render the contents from the page that is assigned to the Posts Page. Adding a blog introduction before all of the posts are rendered improves the user experience, allowing your client to explain the intent of the blog or do a call-to-action.
In this lab, you will build a real-world custom plugin which does the following:
- Turns on the editor for the Posts Page.
- Inserts the content from that editor into the top of the blog page.
As an example, our blog page is the Insights page. Notice how we framed the page title and an introduction.
When you complete this lab, you will have a fully-functional, custom plugin that you can use in any of your projects. You can improve it, add new features, and submit it to the WordPress Plugin Repository if you wish. The point is: you are building a real-world project in this lab.
This Lab is About More Than Building a Single Plugin
This lab is much more than just building a single, use-case plugin. Throughout the lab, you are learning valuable programming skills which make this lab adaptable for your projects and code. You are learning these and so much more:
- Custom plugin – writing it from scratch
- Unregister callbacks
- Investigate a theme
- Database and SQL
- Code construction
- Clean code
- Software principles
- How to think about code
All of these, especially the last four, are essential to you as a software developer. This lab gave you knowledge and skills that you will use in everything you do. When you get done with this lab, you will gain skills and knowledge you just can’t learn anywhere else. Plus, you get a plugin that you can use in your projects.
Works with Any Theme
In this lab, you will see me using the Genesis framework and child theme. However, this lab works on any theme. If you do not have the Genesis framework, no worries. You can use your theme of choice and then locate the proper spot or event in the theme to register for adding in the contents.
In order to do this lab, you will need the following:
- Complete the Let’s Build a Basic WordPress Plugin lab.
- Turn on your local web server (Local, VVV, MAMP, WAMP, DesktopServer, or whatever).
- Open up your favorite editor.
Who needs copy/paste? Right. Writing code from scratch is fun!

Have you ever had the problem where you made a change, pushed it to your client's server, and then they say they can't see the changes? So you tell them to clear their browser's cache and that solves the problem. In this lab, you will learn how to make sure your changes are sent out to the browser using the constant Genesis provides for you.
