The Ultimate Guide to Building a WordPress Plugin
From blogs to complex portals and business websites, millions of sites are powered by WordPress. In fact, 40.2% of all websites are built on the open source content management system (CMS).
Driving the popularity of the platform is a combination of flexibility combined with flexibility. WordPress provides standard functionality to allow any user to make the site work faster.
You can create posts and pages, manage and edit content, assign user roles, upload and upload photos and other media, and comment moderately outside the box.
Suppose you do all that and want to continue building your site by customizing your sign-in page or by adding social evidence to your posts and pages, for example. Since WordPress is open source, you can extend or modify the source code to create almost any functionality your site needs. Such flexibility is a major complaint of WordPress developers.
But what if you are not an engineer and you do not have a lot of coding experience? If so, you can use the plugin.
Plugins are an integral part of WordPress websites that require some functionality.
While the official WordPress site has more than 45,000 plugins from you to choose from, most of these plugins are not lost.
Just because a plugin is in storage does not mean that it will not interfere with its operation or endanger its security.
Now what can you do? You can make your own.
Creating a great WordPress plugin starts with careful planning.
Whether you’re building from scratch, or based on a boilerplate, following well-written good practices is very important.
In this tutorial, you will learn how to create a simple WordPress plugin in the right way.

How do WordPress plugins work?
Plugins allow you to add or increase the functionality of your WordPress site without modifying the main WordPress files. Plugins use access points, officially known as filters and action hooks, provided by the WordPress Plugin API to “enter” the source code. These access points and methods will call for plugin functions from time to time and change the default functionality of WordPress.
How to Use a Plugin in WordPress
There are many ways to add WordPress plugins to your site. For example, you can do that from your dashboard, from the official WordPress directory, or from third-party sites. Plugins from the official directory can be installed automatically with a single click, while other premium plugins must be installed manually via the File Transfer Protocol (FTP) client.
To install the plugin from the official WordPress directory, you must log in to your dashboard and select Plugins> Install New. Then search for the plugin using the built-in search bar. From there, you will have to click install and activate.
To understand how to install a plugin that is not available in the official directory, let’s go back to the plugin example above. If only “Thank you for reading!” The plugin is not available in the directory, then you will download the plugin as a Zip file and save it in the wp-content / plugins folder of your directory via the FTP client. This will automatically install the plugin on your WordPress site.
Then navigate to the Plugins in your Administrator dashboard. Once you have found the newly downloaded plugin from the list of plugins installed on your site, you will just click the plugin link “Activate” and get ready! From then on, every time you publish a post, the line is “Thank you for reading!” will be automatically placed at the bottom of the post.
Most plugins start working right away, but you may need to configure their settings to make sure they work the way you want them to. For example, if you were using the WP Staging – DB & File Duplicator & Migration plugin to set up a site with WordPress programs, you will need to go to the plugin settings page and click on Create New Stage. After that, enter other details such as the site’s site name and what content you want to copy. Otherwise, the plugin would not automatically remove the stage.
If this sounds like a lot of work, you may be wondering why people are using plugins instead of editing key WordPress files to add functionality to their site. That’s because, when you upgrade to a new version of WordPress, all the basic files – as well as any edits made on them – are overwritten. To add the same functionality to your updated site, you’ll need to go back and edit the key files again.
However, if you are installing plugins to add functionality to your site, you will need to worry about keeping the plugins updated.
Now that we understand what plugins are, how they work, and how to use them, let’s take a look at some plugins that can add important features to your WordPress site.
