Overview: What are plugins?

Plugins are the packages of code that extend the functionality of a WordPress site. These plugins are made using PHP codes and even include other vital assets like images, CSS, and JavaScript.

Creating your own plugin will ensure the fact that you’re adding additional functionality over what WordPress offers.

What are WordPress Plugins?

WordPress has more than 55,000+ plugins in its directory that introduce custom functionality to the site it has been added to. Additionally, these plugins carry forward the functionality of adding new features without opting out to change the code.

There are various free and premium plugins available for one to choose from, but there may be chances when you need some particular WordPress functions on your site that aren’t available. For that, you may be required to build your own WordPress plugin.

Sounding that way too technical? Is it? You aren’t required to play with code. All you need to do is to follow some simple steps, and, in the end, you’ll be left is a custom WordPress plugin with features and functions of your choice.

This is a WordPress plugin development tutorial in which you’ll learn the steps to create a custom plugin for your site.

Why would you create a plugin?

Most of us add functionality to the theme instead of creating a new plugin. One can face many situations where doing so would work well, but there are other cases as well where creating a WordPress plugin is way better than adding custom functionality to a theme.

Now you might ask why?

Let’s understand this with the help of an example.

Let’s say you wish to add functionality to your site that changes the default gravatar to the custom gravatar of an individual. Now, if you add this functionality to the theme, then it might just not work if you switch to different themes. On the other hand, if you decide you stick to a plugin, then it would still work even if you switch themes.

As of now you’re well aware of what WordPress plugins are and why you must create it, now let’s explore the steps involved in creating a custom WordPress plugin.
