# HVAC Community Events - Project Status

**Last Updated:** February 6, 2026
**Current Session:** Zoho CRM Sync Fix
**Version:** 2.2.6 (Deployed to Production)

---

## 🎯 NEXT SESSION - CAPTCHA IMPLEMENTATION

### Status: 📋 **PLANNED**

**Objective:** Add CAPTCHA to all user-facing forms to prevent spam and bot submissions.

**Forms to Update:**
- Training login form
- Trainer registration form
- Contact forms (trainer, venue)
- Any other public-facing forms

### Post-Deploy Action Required
On production, go to **wp-admin > HVAC Community Events > Zoho CRM Sync**, click **"Force Full Re-sync (Reset Hashes)"**, then click each sync button or wait for the hourly scheduled sync. This clears poisoned hashes from prior failed syncs so all records re-sync with the new validated code.

## 🎯 CURRENT SESSION - ZOHO CRM SYNC FIX (Feb 6, 2026)

### Status: ✅ **COMPLETE - Deployed to Production**

**Objective:** Fix Zoho CRM integration that appeared connected but was silently failing to sync data (events, attendees, ticket sales not appearing in Zoho CRM).

### Root Cause Analysis (4-model consensus: GPT-5, Gemini 3, Zen Code Review, Zen Debug)

The sync pipeline had a "silent failure" architecture:
1. **Connection test only uses GET** - bypasses staging write block, giving false confidence
2. **Staging mode returned fake `'status' => 'success'`** for blocked writes - appeared successful
3. **Sync methods unconditionally updated `_zoho_sync_hash`** after any "sync" - poisoned hashes
4. **Subsequent syncs compared hashes, found matches, skipped all records** - permanent data loss
5. **No API response validation** - even real Zoho errors were silently ignored

### Fixes Implemented

1. **API Response Validation** (`includes/zoho/class-zoho-sync.php`)
   - Added `validate_api_response()` helper method
   - Checks for WP_Error, staging mode blocks, HTTP errors, Zoho error codes
   - Confirms success with ID extraction before treating a sync as successful

2. **Hash-Only-On-Success** (`includes/zoho/class-zoho-sync.php`)
   - All 5 sync methods (events, users, attendees, rsvps, purchases) rewritten
   - `_zoho_sync_hash` only updates when Zoho API confirms the write succeeded
   - Failed syncs increment `$results['failed']` with error details
   - Changed `catch (Exception)` to `catch (\Throwable)` for comprehensive error handling

3. **Staging Mode Detection Fix** (`includes/zoho/class-zoho-crm-auth.php`)
   - Replaced fragile `strpos()` substring matching with `wp_parse_url()` hostname comparison
   - Production (`upskillhvac.com` / `www.upskillhvac.com`) explicitly whitelisted
   - All other hostnames default to staging mode
   - `HVAC_ZOHO_PRODUCTION_MODE` / `HVAC_ZOHO_STAGING_MODE` constants can override
   - Staging fake responses now return `'skipped_staging'` instead of misleading `'success'`

4. **Admin UI: Hash Reset & Staging Warning** (`includes/admin/class-zoho-admin.php`, `assets/js/zoho-admin.js`)
   - Added `reset_sync_hashes()` AJAX handler - clears all `_zoho_sync_hash` from postmeta and usermeta
   - Added "Force Full Re-sync (Reset Hashes)" button with confirmation dialog
   - Connection test now surfaces staging warning when staging mode is active

5. **Staging Environment Fix** (staging `wp-config.php`)
   - Removed `HVAC_ZOHO_PRODUCTION_MODE` constant from staging wp-config.php
   - Staging now correctly blocks all Zoho write operations via hostname detection
   - GET requests (reads) still pass through for testing

### Files Modified

## 📋 PREVIOUS SESSION - NEAR ME BUTTON MOBILE FIX (Feb 6, 2026)

### Status: ✅ **COMPLETE - Deployed to Staging**

**Objective:** Fix mobile layout issue where the "Near Me" button caused the search bar to shrink when location was granted.

### Issues Found & Fixed

1. ✅ **CSS/HTML Button Structure Bug** (`assets/js/find-training-filters.js`)
   - When the Near Me button state changed, the HTML was replaced without the `.hvac-btn-text` wrapper class
   - On mobile, CSS hides `.hvac-btn-text`, but unwrapped text was visible causing layout issues
   - Fixed in 5 locations: loading state, success state, error reset, clear filters, remove location filter

2. ✅ **No Feedback for Empty Results** (`assets/js/find-training-filters.js`)
   - When "Near Me" filter returned no results within 100km, user saw empty map with no explanation
   - Added notification: "No trainers, venues, or events found within 100km of your location. Try removing the 'Near Me' filter to see all results."

### Files Modified

| File | Change |
|------|--------|
| `assets/js/find-training-filters.js` | Fixed button HTML to preserve `.hvac-btn-text` wrapper; added empty results notification |

### Code Changes

**Button HTML Fix (5 locations):**
```javascript
// Before (broken on mobile):
$button.html('<span class="dashicons dashicons-yes-alt"></span> Near Me');

// After (correct):
$button.html('<span class="dashicons dashicons-yes-alt"></span><span class="hvac-btn-text">Near Me</span>');
```

**Empty Results Notification:**
```javascript
if (self.userLocation) {
    const totalResults = HVACTrainingMap.trainers.length +
                         HVACTrainingMap.venues.length +
                         HVACTrainingMap.events.length;
    if (totalResults === 0) {
        self.showLocationError('No trainers, venues, or events found within 100km...');
    }
}
```

### Mobile Testing Performed
- ✅ 375x812 (iPhone X) - Map and markers display correctly
- ✅ 320x568 (iPhone SE) - Map and markers display correctly
- ✅ Cluster markers expand on click
- ✅ Individual trainer markers clickable
- ✅ Info windows display correctly
- ✅ Profile modal opens and displays correctly

## 📋 PREVIOUS SESSION - CHAMPION DIFFERENTIATION ON FIND TRAINING (Feb 2, 2026)

### Status: ✅ **COMPLETE - Deployed to Production**

**Objective:** Differentiate measureQuick Certified Champions from Trainers on the Find Training map. Champions do not offer public training, so they should be displayed differently.

### Changes Made

1. ✅ **Backend Data** (`includes/find-training/class-hvac-training-map-data.php`)
   - Added `is_champion` flag for trainers with "Certified measureQuick Champion" certification
   - Champions return empty `city` field (only state shown)

2. ✅ **Champion Marker Icon** (`assets/js/find-training-map.js`)
   - Added `getChampionIcon()` method with white outline (vs green for Trainers)
   - Champions use distinct visual appearance on map

3. ✅ **Sidebar Cards** (`assets/js/find-training-map.js`)
   - Champions show only state (e.g., "Ohio" not "Canton, Ohio")
   - Champions have non-clickable cards (no modal popup)
   - Added `hvac-champion-card` CSS class

4. ✅ **Info Windows** (`assets/js/find-training-map.js`)
   - Champions show only state in location
   - No "View Profile" button for Champions
   - Fixed location formatting to handle empty city gracefully

5. ✅ **Sorting** (`assets/js/find-training-map.js`)
   - Champions sorted to end of trainer list
   - Secondary sort by name for stable ordering
   - Applied to both `loadMapData` and `loadTrainerDirectory`

6. ✅ **CSS Styling** (`assets/css/find-training-map.css`)
   - Champion cards have non-clickable appearance
   - No hover effects (cursor: default, no transform/shadow)

### Files Modified

| File | Change |
|------|--------|
| `includes/find-training/class-hvac-training-map-data.php` | Added `is_champion` flag, empty city for champions |
| `assets/js/find-training-map.js` | Champion icon, card display, click prevention, sorting |
| `assets/css/find-training-map.css` | Champion card non-clickable styling |

### Verification (Staging)
- ✅ API returns `is_champion: true` for 18 champions
- ✅ Champions have empty city in API response
- ✅ Champions sorted to end of list
- ✅ Champion cards show only state
- ✅ Clicking champion card does NOT open modal
- ✅ Clicking trainer card DOES open modal (regression test)

### Code Review Findings (Gemini 3)
- **Fixed:** Location formatting bug - empty city could show ", California"
- **Fixed:** Unstable sort order - added secondary sort by name

## 📋 PREVIOUS SESSION - TABBED INTERFACE FOR FIND TRAINING (Feb 1, 2026)

### Status: ✅ **COMPLETE - Deployed to Production**

**Objective:** Refactor the Find Training page sidebar from a single trainer list to a tabbed interface with Trainers, Venues, and Events tabs.

### Changes Made

1. ✅ **Tab Navigation System** (`templates/page-find-training.php`)
   - Replaced "42 trainers" header with three tabs: Trainers | Venues | Events
   - Each tab displays dynamic count in parentheses
   - ARIA accessibility attributes (role="tablist", role="tab", aria-selected)
   - Keyboard navigation (arrow keys, Home, End)

2. ✅ **Visibility Toggles Relocated**
   - Moved from map overlay to sidebar header
   - Colored dots (teal/orange/purple) match marker colors
   - Only control map marker visibility, not tab content

3. ✅ **Venue Cards** (`assets/js/find-training-map.js`)
   - Name with building icon
   - City, State location
   - "X upcoming events" count

4. ✅ **Event Cards** (`assets/js/find-training-map.js`)
   - Date badge showing month/day
   - Event title
   - Venue name
   - Cost display
   - "Past" badge for past events

5. ✅ **Info Modal** (`templates/page-find-training.php`)
   - "What is Upskill HVAC?" section
   - "How to Use" instructions
   - Map Legend (trainer/venue/event markers)

6. ✅ **Context-Aware Search** (`assets/js/find-training-filters.js`)
   - Placeholder changes based on active tab
   - Client-side filtering for instant results (150ms debounce)
   - Falls back to server-side when filters active

7. ✅ **CSS Styling** (`assets/css/find-training-map.css`)
   - Tab navigation container and button styles
   - Venue card and event card layouts
   - Info button and modal styling
   - Responsive adjustments for tablet/mobile

### Files Modified

| File | Change |
|------|--------|
| `templates/page-find-training.php` | Tab navigation, panels, info modal |
| `assets/js/find-training-map.js` | Tab switching, card creators, grid renderers |
| `assets/js/find-training-filters.js` | Context-aware search, client-side filtering |
| `assets/css/find-training-map.css` | ~300 lines new CSS for tabs, cards, modal |
| `includes/class-hvac-plugin.php` | Version bump 2.2.5 → 2.2.6 (CDN cache bust) |

### Issue Resolved: CDN Cache

**Problem:** After deployment, browser loaded old JavaScript without new `initTabs` method.

**Root Cause:** CDN cached old assets. Deploy script clears WP/OPcache but not CDN edge cache.

**Fix:** Bumped `HVAC_VERSION` from 2.2.5 to 2.2.6, changing script URL query string to force cache refresh.

### Verified on Staging
- ✅ 42 trainers tab count
- ✅ 9 venues tab count
- ✅ 8 events tab count
- ✅ Tab switching works with proper ARIA attributes
- ✅ Venue cards display correctly
- ✅ Event cards with date badges display correctly
- ✅ Info modal opens and displays content
- ✅ Visibility toggles control map markers

## 📋 PREVIOUS SESSION - MEASUREQUICK APPROVED TRAINING LABS (Feb 1, 2026)

### Status: ✅ **COMPLETE - Deployed to Staging, Venues Displaying Correctly**

**Objective:** Transform /find-training to showcase only measureQuick Approved Training Labs with venue categories, equipment/amenities tags, and contact forms.

1. ✅ **Venue Taxonomies Created** (`includes/class-hvac-venue-categories.php` NEW)
   - `venue_type` - For lab classification (e.g., "measureQuick Approved Training Lab")
   - `venue_equipment` - Furnace, Heat Pump, AC, Mini-Split, Boiler, etc.
   - `venue_amenities` - Coffee, Water, Projector, WiFi, Parking, etc.
   - All taxonomies registered on `tribe_venue` post type

2. ✅ **9 Approved Training Labs Configured** (via WP-CLI script)
   - Fast Track Learning Lab (ID: 6631) - Joe Medosch
   - Progressive Training Lab (ID: 6284) - Samantha Brazie
   - NAVAC Technical Training Center (ID: 6476) - Andrew Greaves
   - Stevens Equipment Supply - Phoenix (ID: 6448) - Robert Cone
   - San Jacinto College South Campus (ID: 6521) - Terry McWilliams
   - Johnstone Supply - Live Fire Training Lab (ID: 4864) - Dave Petz
   - Stevens Equipment Supply - Johnstown (ID: 1648) - Phil Sweren
   - TruTech Tools Training Center (NEW) - Val Buckles
   - Auer Steel & Heating Supply (NEW) - Mike Breen

3. ✅ **Map Data Filtered by Taxonomy**
   - `get_venue_markers()` now includes `tax_query` for `mq-approved-lab` term
   - Only approved training labs appear as venue markers
   - Equipment, amenities, and POC data included in venue info

4. ✅ **Venue Modal Enhanced**
   - Equipment badges (teal outline chips)
   - Amenities badges (gray outline chips)
   - Contact form with name, email, phone, company, message
   - POC receives email notification on submission

5. ✅ **6 POC Trainer Accounts Created**
   - Samantha Brazie, Andrew Greaves, Terry McWilliams
   - Phil Sweren, Robert Cone, Dave Petz
   - All with `hvac_trainer` role and approved status

### Files Created

| File | Description |
|------|-------------|
| `includes/class-hvac-venue-categories.php` | Venue taxonomy registration (singleton) |
| `scripts/setup-approved-labs.php` | WP-CLI script to configure all labs |
| `scripts/check-venue-coordinates.php` | Diagnostic script to verify venue coordinates |
| `scripts/geocode-approved-labs.php` | Geocode venues missing coordinates |

### Files Modified

| File | Change |
|------|--------|
| `includes/class-hvac-plugin.php` | Load venue categories class |
| `includes/find-training/class-hvac-training-map-data.php` | Add tax_query filter, include equipment/amenities |
| `includes/class-hvac-ajax-handlers.php` | Add venue contact form AJAX handler |
| `templates/page-find-training.php` | Add equipment/amenities badges, contact form |
| `assets/js/find-training-map.js` | Render badges, bind contact form handler |
| `assets/css/find-training-map.css` | Equipment/amenities badge styles |

### Issue Resolved: Venues Now Displaying on Map ✅

**Root Cause:** `venue_type` taxonomy wasn't being registered when `get_venue_markers()` ran.

`HVAC_Venue_Categories::instance()` was instantiated at 'init' priority 5, but then tried to add hooks to 'init' priority 5 for taxonomy registration. Since WordPress was already processing priority 5 handlers, the hook never fired.

**Fix Applied:**
1. **`includes/class-hvac-venue-categories.php`** - Added `did_action('init')` check in constructor
   - If 'init' has already fired, call `register_taxonomies()` and `create_default_terms()` directly
   - Otherwise, use the standard hook approach

2. **`includes/find-training/class-hvac-training-map-data.php`** - Fixed HTML entity encoding
   - Venue names now use `html_entity_decode()` to properly display `&` and `–` characters
   - Event titles also fixed

**Result:**
- ✅ All 9 approved training labs now display as orange venue markers on the map
- ✅ Venue names display correctly (e.g., "Auer Steel & Heating Supply" not "Auer Steel &#038;...")
- ✅ Marker clustering works with mixed trainer/venue markers

## 📋 PREVIOUS SESSION - FIND TRAINING PAGE IMPLEMENTATION (Jan 31 - Feb 1, 2026)

### Status: ✅ **COMPLETE - Deployed to Production**

**Objective:** Replace the buggy MapGeo-based `/find-a-trainer` page with a new `/find-training` page built from scratch using Google Maps JavaScript API.

### Why This Change
The existing IGM/amCharts implementation had a fundamental bug that corrupted marker coordinates (longitude gets overwritten with latitude). After multiple fix attempts, building fresh with Google Maps API provides:
- Full control over marker data
- No third-party plugin dependencies
- Better long-term maintainability
- Ability to show both trainers AND venues

## 📋 PREVIOUS SESSION - TEC COMMUNITY EVENTS DEPENDENCY ANALYSIS (Jan 5, 2026)

### Status: ✅ **COMPLETE - Documented as Technical Debt**

**Objective:** Analyze whether "The Events Calendar: Community" (TEC CE) plugin is still being used after recent refactoring.

**Findings:**
- The plugin **still actively relies on TEC CE** for event creation/editing
- Core shortcode `[tribe_community_events]` is used in 7 template/class files
- TEC CE hooks are used for field processing and form customization
- `HVAC_Event_Manager` has custom CRUD capabilities but production paths use TEC CE

**Removal Scope:**
- **Estimated effort:** 9-14 days of development
- **Key work:** Custom forms, date pickers, validation, template updates, testing
- **Risk:** Recurring events complexity, Event Tickets integration

**Decision:** Deferred as technical debt. Current implementation is functional and stable.

### Deliverables
1. ✅ **Analysis Report:** `docs/reports/TEC-COMMUNITY-EVENTS-DEPENDENCY-ANALYSIS.md`
2. ✅ **CLAUDE.md Updated:** Added Technical Debt section
3. ✅ **Status.md Updated:** This entry

## 📋 PREVIOUS SESSION - SCHEDULED SYNC PERSISTENCE FIX (Dec 20, 2025)

### Status: ✅ **COMPLETE - Deployed to Production**

**Problem:** Scheduled sync showed "Not Scheduled" after page refresh, even though settings were saved correctly.

**Root Cause:**
- `HVAC_Zoho_Scheduled_Sync` was only loaded in admin context
- On non-admin requests (including WP-Cron), custom cron schedules weren't registered
- WordPress was clearing cron events because it didn't recognize the schedules

### Fixes Applied
1. ✅ **Load Scheduled Sync on ALL Requests** (`class-hvac-plugin.php`)
   - Moved `HVAC_Zoho_Scheduled_Sync::instance()` initialization to main plugin loader
   - Now loads alongside other schedulers (like Communication Scheduler)
   - Ensures cron schedules and action hooks are always registered

2. ✅ **Add `add_option` Hook** (`class-zoho-scheduled-sync.php`)
   - Added `add_option_hvac_zoho_auto_sync` hook for first-time setting creation
   - WordPress fires `add_option_` (not `update_option_`) on first save

3. ✅ **Explicit Scheduling in Save** (`class-zoho-admin.php`)
   - `save_settings()` now explicitly calls `schedule_sync()` or `unschedule_sync()`
   - Ensures scheduling works even when option value hasn't changed
   - `update_option_` hook only fires when value actually changes

### Files Modified
- `includes/class-hvac-plugin.php` - Load scheduled sync globally
- `includes/zoho/class-zoho-scheduled-sync.php` - Add first-time option hook
- `includes/admin/class-zoho-admin.php` - Explicit scheduling call

---

## 📋 PREVIOUS SESSION - PUBLIC MAP & DIRECTORY FIX (Dec 21, 2025)

### Status: 🔄 **IN PROGRESS - Deployed to Staging (Strategy H)**

**Problem:** Map markers missing. Data analysis reveals markers have identical Latitude and Longitude values (corruption).

**Root Cause:**
- IGM Plugin's client-side processing corrupts `longitude` by overwriting it with `latitude` immediately before rendering.
- Previous PHP Injection strategies (D-G) caused 500 errors due to `WP_Query` timing/context issues in the footer.

**Solution (Strategy H):**
1. ✅ **Javascript Interceptor:** Injected a robust interceptor script in `class-hvac-mapgeo-integration.php`.
2. ✅ **Mechanism:** Uses `Object.defineProperty` on `window.iMapsData` to catch the data assignment *before* the map plugin sees it.
3. ✅ **Repair Logic:** Detects corrupted markers (Lat == Lng) and instantly restores correct values from safe `lat`/`lng` backup keys provided by PHP.
4. ✅ **Cleanup:** Removed dangerous PHP query injections that were causing server errors.

**Current Status:**
- Fix deployed to Staging.
- Pending verification of visible markers and "Healed" console logs.

**Next Steps:**
1. Verify map renders correctly on Staging.
2. Deploy to Production.

## 📋 PREVIOUS SESSION - BATCH SYNC ENHANCEMENT (Dec 18, 2025)

### Status: ✅ **COMPLETE - All Sync Tasks Now Auto-Iterate with Progress Bar**

**Summary:** 
- **All 5 Sync Types:** Now support batch pagination with auto-continue
- **Progress Bar:** Visual feedback showing `X of Y processed (N%)`

- **Orphan Cleanup:** Deleted 14 test attendees referencing deleted events

### Changes Made
1. ✅ **Backend Pagination:**
   - All sync methods (`sync_events`, `sync_users`, `sync_attendees`, `sync_rsvps`, `sync_purchases`) now accept `$offset` and `$limit` parameters
   - Each returns `has_more`, `next_offset`, and `total` for pagination
   - Admin endpoint updated to pass offset to sync methods
2. ✅ **Frontend Progress UI:**
   - New `syncWithProgress()` function replaces single AJAX calls
   - Auto-continues batches until complete

## 📋 PREVIOUS SESSION - ZOHO CRM ATTENDEE SYNC (Dec 17-18, 2025)

### Status: ✅ **COMPLETE - All Attendees Syncing Successfully**

**Summary:** 
- **Events Sync:** ✅ WORKING. 39 events synced with enhanced field mapping.
- **Attendees Sync:** ✅ WORKING. 50/50 synced, 0 errors, all contacts updated with custom fields.

### Issues Resolved
1. ✅ **Campaign Member Linking:**
   - Fixed API endpoint: `PUT /Contacts/{id}/Campaigns` (was `/Campaigns/{id}/Contacts/{id}`)
   - Fixed `log_debug()` visibility (private → public)
2. ✅ **Attendee Field Mapping:**
   - measureQuick Email → `Email` (primary, used for lookup)
   - Attendee Email → `Secondary_Email`
   - Attendee Cell Phone → `Mobile`
   - Company Role → `Primary_Role`
   - Fixed meta key: `_tec_tickets_commerce_attendee_fields` with hyphenated field names
3. ✅ **Email Fallback Logic:**
   - If attendee email empty, use measureQuick email (and vice versa)
   - Only fails if BOTH emails are empty
4. ✅ **DUPLICATE_DATA Handling:**
   - When Zoho returns "duplicate exists", extract existing contact ID from error
   - Use that ID to update instead of failing
5. ✅ **Existing Contact Updates:**
   - Existing contacts now updated via PUT with new field data on each sync
