by

WordPress plugins allow you to add new features to your website without changing the core WordPress files. In this tutorial, I will show you how to create your first WordPress plugin step by step, even if you are a beginner.

By the end of this guide, you will have a working custom plugin that adds a feature to your site.

✅ What You Need

  • A WordPress website installed

  • Access to your hosting file manager or FTP

  • Basic knowledge of PHP (not required, but helpful)

📁 Step 1: Create Plugin Folder

Go to:

/wp-content/plugins/

Create a new folder:

my-first-plugin

📄 Step 2: Create Main Plugin File

Inside that folder, create a file:

my-first-plugin.php

🧠 Step 3: Add Plugin Header Code

Open my-first-plugin.php and paste this:

<?php
/**
* Plugin Name: My First Plugin
* Plugin URI: https://yourwebsite.com
* Description: This is my first WordPress plugin.
* Version: 1.0
* Author: Your Name
* Author URI: https://yourwebsite.com
*/

Save the file.

🔌 Step 4: Activate the Plugin

Go to:

WordPress Dashboard → Plugins → Installed Plugins

You will see:

My First Plugin

Click Activate.

🎉 Congratulations! You have created your first WordPress plugin.

🛠 Step 5: Add a Simple Feature

Now let’s make the plugin do something.

Add this code below the header:

add_action('wp_footer', 'mfp_show_message');

function mfp_show_message() {
echo ‘<p style=”text-align:center;color:green;”>My First Plugin is working!</p>’;
}

Save the file and refresh your website.

✅ You will see a message in the footer of your site.

🧪 How This Works

  • add_action() connects your function to WordPress

  • wp_footer runs when the footer loads

  • echo prints text on the screen

📦 Final Plugin Code

Your complete file should look like this:

<?php
/**
* Plugin Name: My First Plugin
* Plugin URI: https://yourwebsite.com
* Description: This is my first WordPress plugin.
* Version: 1.0
* Author: Your Name
* Author URI: https://yourwebsite.com
*/add_action(‘wp_footer’, ‘mfp_show_message’);

function mfp_show_message() {
echo ‘<p style=”text-align:center;color:green;”>My First Plugin is working!</p>’;
}
