📌 Engineering Overview

This project serves as a technical demonstration of Object-Oriented Programming (OOP) within the WordPress ecosystem. It focuses on the strict separation of business logic from the presentation layer (UI).

🎯 Key Engineering Standards

Strict Typing & Sanitization: Uses floatval() and esc_html() to prevent XSS and ensure data integrity.
Abstraction: Core calculations are handled via private class methods to prevent external tampering.
WordPress Coding Standards: Adheres to the "Plugin Header" requirements for proper WordPress initialization.

🛠️ Tech Stack

PHP: Version 7.4+ (Class-based structure)
WordPress API: Shortcode API
Environment: WordPress Core

🚀 How It Works

The engine uses a dedicated Class TaxLogicEngine to handle dynamic tax calculations for international e-commerce contexts.

Usage

Place the following shortcode on any page or post: [calculate_tax amount="500" rate="12"]

📂 File Structure

tax-logic-pro.php: Main plugin file containing the Class logic and security checks.
.gitignore: Standard WordPress exclusion rules.
