# HVAC Community Events Plugin Refactoring Plan

## Overview
The plugin has decent structure but needs improvements in several areas:

## 1. Debug Logging Cleanup
- **Issue**: Excessive debug logging throughout codebase
- **Solution**: 
  - Create a centralized logging class
  - Use conditional logging based on WP_DEBUG or custom debug flag
  - Remove or consolidate redundant log statements

## 2. Class Organization
- **Issue**: Inconsistent namespace usage and class dependencies
- **Solution**:
  - Implement proper PSR-4 autoloading
  - Use consistent namespacing throughout
  - Create proper singleton patterns for main classes

## 3. Security Enhancements
- **Issue**: Input validation could be improved in several areas
- **Solution**:
  - Add more robust nonce verification
  - Implement stricter capability checks
  - Add proper escaping for all outputs

## 4. Database Query Optimization
- **Issue**: Multiple queries for dashboard stats, inconsistent approach to querying events
- **Solution**:
  - Consolidate queries where possible
  - Use proper WordPress caching mechanisms
  - Fix the inconsistency between post_author and _EventOrganizerID

## 5. Registration Form Improvements
- **Issue**: Very large single class (1066 lines) handling too many responsibilities
- **Solution**:
  - Split into separate classes for validation, user creation, notifications
  - Create a form builder pattern
  - Implement better error handling with proper exceptions

## 6. Template System
- **Issue**: Direct include of templates without proper hooks
- **Solution**:
  - Implement proper template hierarchy
  - Add filters for template overrides
  - Use locate_template pattern

## 7. Asset Management
- **Issue**: Basic enqueuing without version control or dependencies
- **Solution**:
  - Implement asset versioning based on file modification times
  - Add proper dependency management
  - Minify production assets

## 8. Code Standards
- **Issue**: Mixed coding standards and formatting
- **Solution**:
  - Implement WordPress Coding Standards
  - Use PHP_CodeSniffer with WordPress rules
  - Add proper PHPDoc comments

## 9. Testing Infrastructure
- **Issue**: No proper unit tests
- **Solution**:
  - Add PHPUnit test infrastructure
  - Create test doubles for WordPress functions
  - Implement integration tests for critical paths

## 10. Configuration Management
- **Issue**: Hard-coded values and paths
- **Solution**:
  - Create configuration class
  - Use WordPress options API properly
  - Implement settings page for admin configuration

## Implementation Priority
1. Debug logging cleanup (Quick win)
2. Security enhancements
3. Registration form refactoring
4. Database optimization
5. Code standards implementation
6. Template system improvements
7. Testing infrastructure
8. Asset management
9. Configuration management
10. Full namespace implementation
