Phase 2: TEC Community Events Integration Analysis

Comprehensive Page Audit & Refactoring Strategy

Date: September 25, 2025 Status: Phase 1 Complete - Moving to Phase 2 Frontend Refactoring Current Branch: feature/native-event-system Implementation Plan: TEC-COMMUNITY-EVENTS-REPLACEMENT-PLAN.md

---

Executive Summary

Based on comprehensive analysis of the codebase, Phase 1 foundation integration is complete with the HVAC Event Form Builder successfully integrated and operational. This analysis documents the current state of TEC Community Events usage and provides a strategic refactoring plan for Phase 2 implementation.

Key Finding: The system already has substantial native HVAC event management capabilities that can replace TEC Community Events forms while preserving TEC Core integration.

Current TEC Community Events Usage Analysis

Primary TEC Integration Points Identified

1. Event Creation & Management Templates

• page-tec-create-event.php: Uses iframe to embed TEC Community Events form (/events/network/add/)
• page-manage-event.php: Uses [tribe_community_events] shortcode
• page-manage-event-integrated.php: HVAC native implementation with TEC Core integration
• community-edit-event-prototype.php: Custom template override with excerpt field

2. Event Listing & Display

• page-tec-my-events.php: Native HVAC implementation using tribe_events queries
• All event display uses TEC Core: No Community Events dependency for display

3. URL Structure & Routing

Current TEC Community Events URLs:
/events/network/add/          → TEC Community Events create form
/events/community/edit/{id}/  → TEC Community Events edit form

Target HVAC Native URLs:
/trainer/events/create/       → HVAC native create form ✅ Ready
/trainer/events/edit/{id}/    → HVAC native edit form ✅ Ready
/trainer/events/my-events/    → HVAC native event list ✅ Working

TEC Community Events Replacement Strategy

URLs to Replace (Phase 2 Target):

OLD: /events/network/add/
NEW: /trainer/events/create/ ✅ (HVAC native form ready)

OLD: /events/community/edit/{id}/
NEW: /trainer/events/edit/{id}/ ✅ (HVAC native form ready)

OLD: iframe TEC embed in page-tec-create-event.php
NEW: Direct HVAC form in page-hvac-form.php ✅ (Template ready)

---

Page-by-Page Refactoring Plan

Priority 1: HIGH IMPACT (Week 2, Days 1-2)

1. Replace page-tec-create-event.php

Current: iframe TEC Community Events form Target: Direct HVAC_Event_Form_Builder implementation Template: page-hvac-form.php (ready) Effort: 2 hours - Remove iframe, implement native form

2. Replace page-manage-event.php

Current: [tribe_community_events] shortcode Target: Use existing page-manage-event-integrated.php Effort: 1 hour - Redirect traffic to integrated version

Priority 2: MEDIUM IMPACT (Week 2, Days 3-4)

3. Enhance page-manage-event-integrated.php

Current: Basic HVAC implementation Target: Full template system integration Features to Add:

• Template selector dropdown
• "Save as Template" functionality
• Progressive disclosure for advanced options
• Auto-save functionality

4. Update page-tec-my-events.php

Current: Already native HVAC (✅ no changes needed) Action: Validate functionality, add template integration

Priority 3: LOW IMPACT (Week 2, Day 5)

5. Remove community-edit-event-prototype.php

Current: Template override with excerpt field Action: Merge excerpt functionality into native HVAC forms

6. URL Cleanup & SEO Preservation

Action: Ensure all old TEC Community Events URLs redirect properly
