Care Book Block Ultimate

Advanced appointment control system for KiviCare - Hide doctors/services with intelligent CSS-first filtering approach.

🚀 Features

• CSS-First Filtering: Instant hiding of restricted doctors/services without page reload
• Modern PHP 8.3: Leverages latest PHP features (readonly classes, enums, typed properties)
• WordPress Integration: Native WordPress hooks and security
• KiviCare Compatible: Works seamlessly with KiviCare 3.6.8+
• Performance Optimized: <1.5% page load overhead with intelligent caching
• Admin Interface: Easy-to-use toggle system for managing restrictions
• Bulk Operations: Manage multiple restrictions efficiently
• MySQL 8.0+ Optimized: Advanced indexing and JSON metadata support

📋 System Requirements

• WordPress: 6.0+ (Tested up to 6.8)
• PHP: 8.1+ (Recommended: 8.3+)
• MySQL: 8.0+
• KiviCare Plugin: 3.6.8+

🏗️ Architecture

Modern PHP 8+ Features

• Readonly Classes: Immutable data models for security
• Enums: Type-safe restriction types
• Strict Typing: declare(strict_types=1) throughout
• PSR-4 Autoloading: Modern namespace organization

CSS-First Approach

The plugin uses a CSS-first strategy to hide elements immediately on page load, preventing FOUC (Flash of Unstyled Content) and ensuring smooth user experience.

Database Schema (MySQL 8.0+)

Custom table wp_care_booking_restrictions with JSON metadata support and optimized indexing for high-performance queries.

Security Framework (Multi-Layer)

1. WordPress nonces for CSRF protection
2. Capability checking for admin access
3. Input validation with PHP 8+ type safety
4. Output escaping and sanitization
5. Rate limiting for AJAX endpoints
6. Health monitoring and alerting
7. Audit logging system

🎯 Performance Targets (Updated)

• Page Load Overhead: <1.5% (improved with PHP 8.3)
• Admin AJAX Response: <75ms (MySQL 8.0 optimization)
• Restriction Toggle: <200ms (enhanced caching)
• Cache Hit Ratio: >98% (intelligent invalidation)
• Memory Usage: <8MB (PHP 8+ efficiency)

🧪 Testing Strategy

RED-GREEN-Refactor TDD with modern PHPUnit 10+:

# Install dev dependencies (requires PHP extensions)
composer install --dev

# Run unit tests
composer test

# Run with coverage report
composer test:coverage

# Code quality checks
composer quality

🔧 Development Guidelines

Modern PHP Standards

• PHP 8.1+: Required minimum version
• Strict Types: declare(strict_types=1) in all files
• Readonly Properties: Use for immutable data
• Enums: Type-safe constants
• Match Expressions: Instead of switch statements

Database Best Practices

• MySQL 8.0+ Features: JSON support, improved indexing
• Prepared Statements: Always use $wpdb->prepare()
• Optimal Indexing: Composite indexes for performance
• Health Monitoring: Built-in performance tracking

Security Implementation

• Multi-Layer Validation: 7-layer security framework
• Type Safety: PHP 8+ strict typing prevents injections
• WordPress Standards: Nonces, capabilities, sanitization
• Real-time Monitoring: Health checks and alerting
