## 🚀 Deployment Steps

### Step 1: Backup Current System

```bash
# Create backup of current template system
cp -r /wp-content/themes/astra-child-hvac/tribe-events/ /backup/tribe-events-$(date +%Y%m%d)/

# Backup current JavaScript files
cp /wp-content/plugins/hvac-community-events/assets/js/* /backup/js-$(date +%Y%m%d)/
```

### Step 2: Deploy Template Files

```bash
# Create theme directory structure
mkdir -p /wp-content/themes/astra-child-hvac/tribe-events/community/
mkdir -p /wp-content/themes/astra-child-hvac/tribe-events/community/partials/

# Copy enhanced template
cp templates/community-edit-event-enhanced.php /wp-content/themes/astra-child-hvac/tribe-events/community/edit-event.php

# Copy partial templates
cp templates/partials/* /wp-content/themes/astra-child-hvac/tribe-events/community/partials/
```

### Step 3: Deploy JavaScript Enhancement

```bash
# Copy enhanced JavaScript file
cp assets/js/hvac-enhanced-field-population.js /wp-content/plugins/hvac-community-events/assets/js/

# Ensure proper permissions
chmod 644 /wp-content/plugins/hvac-community-events/assets/js/hvac-enhanced-field-population.js
```

### Step 4: Update Plugin Integration

Add to `/wp-content/plugins/hvac-community-events/includes/class-hvac-scripts-styles.php`:

```php
/**
 * Enqueue enhanced field population script for TEC forms
 */
public function enqueue_enhanced_tec_scripts() {
    // Only on TEC community event forms
    if ($this->is_tec_event_form()) {
        wp_enqueue_script(
            'hvac-enhanced-field-population',
            HVAC_PLUGIN_URL . 'assets/js/hvac-enhanced-field-population.js',
            array('jquery', 'wp-media'),
            '2.0.0',
            true
        );
        
        // Localize script with WordPress data
        wp_localize_script('hvac-enhanced-field-population', 'hvacEnhanced', array(
            'ajax_url' => admin_url('admin-ajax.php'),
            'nonce' => wp_create_nonce('hvac_enhanced_nonce'),
            'media_upload_nonce' => wp_create_nonce('media-form'),
        ));
    }
}

/**
 * Check if current page is TEC event form
 */
private function is_tec_event_form() {
    return (
        is_page() && 
        (strpos(get_the_content(), '[tribe_community_events_form]') !== false ||
         get_query_var('tribe_events_community') === 'add' ||
         get_query_var('tribe_events_community') === 'edit')
    );
}
```

### Step 5: Update Template Processing

Add to `/wp-content/plugins/hvac-community-events/includes/class-hvac-community-events.php`:

```php
/**
 * Initialize enhanced template processing
 */
public function init_enhanced_template_processing() {
    // Register enhanced field processors
    add_action('tribe_events_community_before_event_save', array($this, 'process_enhanced_fields'), 5);
    
    // Load TEC field processors
    if (class_exists('HVAC_TEC_Field_Processor')) {
        $this->field_processor = new HVAC_TEC_Field_Processor();
        
        // Register individual processors
        $this->field_processor->register_processor('excerpt', new HVAC_TEC_Excerpt_Processor());
        $this->field_processor->register_processor('categories', new HVAC_TEC_Categories_Processor());
        $this->field_processor->register_processor('featured_image', new HVAC_TEC_Featured_Image_Processor());
    }
}

/**
 * Process enhanced fields using new processor system
 */
public function process_enhanced_fields($event_id) {
    if ($this->field_processor) {
        $result = $this->field_processor->process_all_fields($event_id);
        
        if (is_wp_error($result)) {
            HVAC_Logger::error(
                'Enhanced field processing failed: ' . $result->get_error_message(),
                'Enhanced Template',
                array('event_id' => $event_id)
            );
        }
    }
}
```

## 🧪 Testing and Verification

### Step 1: Run Enhanced Template Test

```bash
# Run comprehensive test suite
node test-enhanced-tec-template.js

# Expected output:
# 🎯 Field Population: 100% (12/12)
# 🔍 Field Access: 100% (12/12)  
# 🧪 Individual Tests: 4/4 passed
# 🏆 OVERALL RESULT: ✅ SUCCESS
```

### Step 2: Manual Verification Checklist

**Template Override Verification**:
- [ ] Enhanced template indicator visible
- [ ] All 4 new field sections present (excerpt, categories, featured image, tags)
- [ ] Responsive design working on mobile
- [ ] No JavaScript errors in console

**Field Population Testing**:
- [ ] Excerpt field populates with character counter
- [ ] Categories checkboxes select correctly
- [ ] Featured image field shows preview
- [ ] Tags field adds/removes tags properly

**Accessibility Verification**:
- [ ] Keyboard navigation works for all fields
- [ ] Screen reader announcements working
- [ ] High contrast mode supported
- [ ] Focus management proper

### Step 3: Performance Testing

```javascript
// Test field population performance
const startTime = performance.now();
window.HVACEnhancedFieldPopulation.populateAllFields(testData);
const endTime = performance.now();
console.log(`Field population completed in ${endTime - startTime}ms`);
// Target: < 100ms for 100% population
```

## 🔧 Configuration Options

### Template Customization

**Field Visibility Control**:
```php
// In functions.php or plugin
add_filter('hvac_enhanced_template_fields', function($fields) {
    // Hide tags field for specific user roles
    if (!current_user_can('manage_event_tags')) {
        unset($fields['hvac-tags']);
    }
    return $fields;
});
```

**Field Validation Customization**:
```php
// Custom excerpt validation
add_filter('hvac_tec_excerpt_validation', function($is_valid, $excerpt, $event_id) {
    if (strlen($excerpt) < 50) {
        return new WP_Error('excerpt_too_short', 'Excerpt must be at least 50 characters');
    }
    return $is_valid;
}, 10, 3);
```

### JavaScript Integration

**Custom Field Populators**:
```javascript
// Add custom field populator
window.HVACEnhancedFieldPopulation.addCustomPopulator = function(fieldType, populator) {
    this.debug.FieldPopulators[fieldType] = populator;
};
```

---

## 🚨 Troubleshooting

### Common Issues

**1. Template Not Loading**
```bash
# Check file permissions
ls -la /wp-content/themes/astra-child-hvac/tribe-events/community/
# Should show 644 for files, 755 for directories

# Clear WordPress caches
wp cache flush
wp rewrite flush
```

**2. JavaScript Errors**
```javascript
// Debug field access
window.HVACEnhancedFieldPopulation.testFieldAccess();
// Check console for missing selectors
```

**3. Media Library Not Working**
```php
// Verify WordPress media is enqueued
if (!wp_script_is('wp-media', 'enqueued')) {
    wp_enqueue_media();
}
```

**4. Field Population Failing**
```javascript
// Enable debug mode
window.HVACEnhancedFieldPopulation.debug.enabled = true;
// Check detailed logs for population issues
```

### Error Recovery

**Rollback Procedure**:
```bash
# Restore original template
rm /wp-content/themes/astra-child-hvac/tribe-events/community/edit-event.php
# System automatically reverts to TEC default

# Disable enhanced JavaScript
mv /wp-content/plugins/hvac-community-events/assets/js/hvac-enhanced-field-population.js{,.disabled}
```
