An Introduction to WordPress Plugins

A WordPress plugin is a piece of software that can be installed on a WordPress website to add new features or functionality. Plugins can be developed by anyone, and there are thousands of free and premium plugins available in the official WordPress plugin repository and other marketplaces.

This means that users can add new features to their website without worrying about breaking the core WordPress code or losing their changes during a WordPress update.

Create a new folder in the wp-content/plugins directory of your WordPress installation. The folder’s name should be the name of your plugin in lowercase, with no spaces. For example, if your plugin is called “My Plugin”, the folder should be named “my-plugin”.

Create a new PHP file in the plugin folder and give it the same name as the plugin folder. For example, if the plugin folder is named “my-plugin”, the PHP file should be named “my-plugin.php”.

In the PHP file, define the plugin information, such as the plugin name, version, author, and description, using the header comments. Here’s an example of what the header comments might look like:

<?php
/*
Plugin Name: My Plugin
Plugin URI: http://example.com/my-plugin
Description: This is my plugin description.
Version: 1.0
Author: John Doe
Author URI: http://example.com
License: GPL2
