Understanding how to create simple WordPress plugins and use hooks is essential for WordPress developers and site administrators to customize and secure websites.

Create the plugin file with header

Create a PHP file named wp-security-message.php and add the plugin header comment with these exact details: Plugin Name as WP Security Message, Description as Shows why WordPress security is critical, Version as 1.0, and Author as YourName.

<?php
// Your code here

Hint

The plugin header comment must be at the top of the PHP file and use the exact keys and values.

2

Add function to display security message

Add a function named wp_security_message_notice that echoes a <div> with class notice notice-warning is-dismissible containing the exact text: Keeping WordPress secure protects your site from hackers and data loss.

Wordpress

<?php
/**
 * Plugin Name: WP Security Message
 * Description: Shows why WordPress security is critical
 * Version: 1.0

 */

Wordpress

';
    echo 'Keeping WordPress secure protects your site from hackers and data loss.';
    echo '';
}

// Your code here

Hint

Use add_action with the exact hook name admin_notices and function name wp_security_message_notice.

4

Complete plugin with closing PHP tag omitted

Ensure the plugin file ends without a closing ?> PHP tag to follow WordPress best practices.

Wordpress

';
    echo 'Keeping WordPress secure protects your site from hackers and data loss.';
    echo '';
}

add_action('admin_notices', 'wp_security_message_notice');
