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
