Congratulations! You did it! You built a custom, from scratch meta box for a common task of providing a subtitle for your client. Looking back at the code, there’s a lot of boilerplate logic. That means with a few lines of code you were able to create a custom implementation.
Notice that we hard-coded in the configuration information. That means we have an opportunity to create a reusable boilerplate and meta box generator function, that you can use on every project. We’ll do that in the next lab.
Considering the Impact of 3rd Party Plugins on Your Client
I want to point out to you that you can build your own meta box without a 3rd party plugin. Why? Because meta box plugins are for you, the developer, and not the site owner and those managing the content on the website after you deliver the project. Those exist to make your job easier.
What is that important? Because you are making your client’s website dependent forever on a 3rd party plugin. That plugin is bloated as it needs to handle all the different combinations of different meta box configurations. With a few lines of code, you could eliminate the dependency and unused and bloated code for your client.
These are decisions that developers need to make every day, weighing out the dependencies we place on our clients verses the benefits throughout the software’s lifecycle.
You get WET when you swim. Stay DRY when you code.
