Notice Shortcode Plugin

A simple WordPress plugin that adds a shortcode to display customizable notices on the frontend of a website.

This plugin is built to demonstrate WordPress fundamentals such as plugins, shortcodes, hooks, sanitization, and clean code structure.

Features

• Adds a frontend shortcode to display notices
• Supports custom messages via shortcode attributes
• Uses WordPress best practices
• Sanitizes output for security
• Lightweight and beginner-friendly

Usage

After activating the plugin, use the shortcode inside any post or page:

[notice]

Custom Message Example

You can pass a custom message using an attribute:

[notice message="Welcome! This notice is generated using a shortcode."]

How It Works

• The plugin registers a shortcode using add_shortcode()
• The shortcode callback function returns HTML output
• Default values are handled using shortcode_atts()
• Output is sanitized using esc_html() for security
• Basic styles are injected using the wp_head action hook

Security Practices

• Prevents direct access using ABSPATH check
• Escapes frontend output to avoid XSS attacks
• Follows WordPress coding standards
