WordPress is an incredibly versatile platform that allows users to extend its functionality through plugins. In this article, we will learn how to create a basic plugin from scratch, step by step, with code examples in both Spanish and English.

1: Setting up the Development Environment.

Before we begin, we need to have a development environment set up. Make sure you have a web server with WordPress installed and ready to use.

2: Basic Plugin Structure.

Let’s start by creating the basic structure of our plugin. Create a folder in the WordPress plugins directory, and inside it, create a main file with the plugin information.

// my-plugin/my-plugin.php

3: Adding Functionality.

Let’s add basic functionality to the plugin, for example, displaying a custom message in the admin bar.

// my-plugin/my-plugin.php

Hello, this is your custom message.

'; } // Hook to call the function add_action('admin_notices', 'show_admin_message'); // ... (subsequent code) ?>

4: Plugin Activation and Deactivation.

Let’s add hooks to execute functions when the plugin is activated or deactivated.

// my-plugin/my-plugin.php

5: Hooks.

WordPress is full of hooks to be able to manipulate functionality or content from a plugin or theme. For this example, we will manipulate the content of each post and replace the word wordpress with WordPress, which is the correct way to write this word.
