Creating Your First Simple Plugin
Step-by-Step Guide
Let’s create a simple “Hello World” plugin. Follow these steps.
- Create a New Folder: Inside your WordPress wp-content/plugins directory, create a new folder called hello-world-plugin.
- Create the Main Plugin File: Inside this folder, create a file named hello-world-plugin.php. Add the following code.
<?php
/*
Plugin Name: Hello World Plugin
Description: A simple plugin that displays "Hello World".

*/
function hello_world() {
echo "<p>Hello World!</p>";
}
add_action('wp_footer', 'hello_world');
?>
Adding Functionality
To add more functionality, you can use hooks and filters. For example, to add a custom widget,
Create a Widget Class: Add the following code to your plugin file.
class HelloWorldWidget extends WP_Widget {
function __construct() {
parent::__construct(
'hello_world_widget',
__('Hello World Widget', 'text_domain'),
array('description' => __('A simple Hello World widget', 'text_domain'))
);
}
public function widget($args, $instance) {
echo $args['before_widget'];
echo $args['before_title'] . apply_filters('widget_title', 'Hello World') . $args['after_title'];
echo '<p>Hello World!</p>';
echo $args['after_widget'];
}
}
function register_hello_world_widget() {
register_widget('HelloWorldWidget');
}
add_action('widgets_init', 'register_hello_world_widget');
