# IonCureX - AI/LLM Context and Instructions
# This file provides context about IonCureX for AI assistants and developers

## Project Overview
IonCureX is a business-critical platform serving as the central hub for conference ticket sales and registrations across all IonCure domains. It acts as a secure payment gateway where registration access is only granted after successful payment confirmation.

## Key Business Logic
- Payment-First Flow: Users select tickets → payment processing → registration access
- Secure Gate System: Registration forms remain locked until payment verification
- Dual Gateway Support: PayPal (international) and Razorpay (Indian market)
- Open Access Platform: No user login required, all content publicly viewable

## Technical Architecture
- Frontend: HTML5, CSS3, JavaScript ES6+, Bootstrap 5
- Backend: PHP 8.x, MySQL 8.x
- Hosting: Hostinger shared hosting environment
- Security: PCI DSS compliant payment processing

## File Structure Context
- public_html/: Web root directory (Hostinger requirement)
- config/: Configuration files (database, email, payment gateways)
- classes/: PHP class definitions (PaymentGateway, EmailService, etc.)
- includes/: Reusable components (header, footer, functions)
- templates/: Email templates and reusable HTML components
- assets/: Static files (CSS, JS, images)
- vendor/: Third-party libraries (PHPMailer, payment SDKs)
- uploads/: User-uploaded files (secure access)
- logs/: Application logs (error, payment, security)
- secure/: Outside web root (encrypted credentials and keys)

## Development Guidelines
- Follow MVC-inspired separation of concerns
- Use prepared statements for all database queries
- Implement comprehensive input validation and sanitization
- Maintain PCI DSS compliance for payment processing
- Use AES-256 encryption for sensitive credential storage
- Log all payment transactions and access attempts

## Conference Types
- Vaccines: Immunization and vaccine development conferences
- AI Medicine: Artificial intelligence applications in healthcare
- Neuroscience: Brain research and neurological conferences
- Biotechnology: Biotech innovation and research conferences

## Payment Flow
1. User selects conference and ticket type
2. Geographic detection determines payment gateway (PayPal/Razorpay)
3. Payment processing with transaction ID generation
4. Success/failure callbacks update transaction status
5. Successful payment unlocks registration form access
6. User completes registration with payment reference linking
7. Automated email confirmations sent to user

## Security Considerations
- All payment data encrypted and PCI compliant
- Input sanitization on all user-submitted data
- CSRF protection on forms
- XSS prevention with output encoding
- SQL injection prevention with prepared statements
- Secure session management

## Performance Optimization
- Asset minification and compression
- Browser caching headers
- Database query optimization
- CDN integration where possible
- Mobile-responsive design
