# Sprint 4: Homepage Section Manager - COMPLETED ✅

**Date**: 2025-10-24
**Status**: ✅ Complete
**Overall Progress**: 85% → 95% (+10%)

---

## 🎯 Objectives

Build a WordPress-style section manager in the Theme Customizer allowing users to:
1. View all available homepage sections
2. Toggle sections on/off (show/hide)
3. Reorder sections via drag & drop
4. Preview changes in real-time
5. Publish changes to live website

---

## ✅ What Was Accomplished

### 1. Homepage Sections Panel Created ✅
**New File**: `resources/views/websites/customizer/panels/homepage-sections.blade.php`

**Features Implemented**:
- **Section List Display**: Shows all available theme sections with names and descriptions
- **Drag & Drop Reordering**: SortableJS integration for intuitive section reordering
- **Toggle Visibility**: Bootstrap switches to enable/disable individual sections
- **Bulk Actions**:
  - "Enable All Sections" button
  - "Reset to Default Order" button
- **Visual Feedback**:
  - Drag handle icon for clear interaction cues
  - Hover states and transitions
  - Ghost/drag states during reordering

**User Interface**:
```
┌─────────────────────────────────────┐
│ Homepage Sections                   │
├─────────────────────────────────────┤
│ ≡  Hero Section              [ON]   │
│ ≡  Features Section          [ON]   │
│ ≡  About Section             [OFF]  │
│ ≡  Services Section          [ON]   │
│ ≡  Testimonials Section      [ON]   │
│ ≡  CTA Section               [ON]   │
│ ≡  Contact Section           [OFF]  │
│ ≡  Stats Section             [ON]   │
│ ≡  Products Showcase         [ON]   │
│ ≡  Booking Section           [ON]   │
│ ≡  Team Section              [ON]   │
├─────────────────────────────────────┤
│ [Enable All Sections]               │
│ [Reset to Default Order]            │
└─────────────────────────────────────┘
```

**JavaScript Functionality**:
- Real-time state synchronization with `customizerState.settings.homepage_sections`
- Debounced preview updates (500ms)
- Automatic order tracking during drag operations
- Section data structure:
```javascript
{
    id: 123,               // Theme component ID
    slug: 'features-section',
    enabled: true,         // Visibility flag
    order: 2               // Display order (0-indexed)
}
```

---

### 2. Customizer Integration ✅
**Modified**: `resources/views/websites/customizer/index.blade.php`

**Changes Made**:
1. **Added Navigation Item** (line 279-282):
   - Icon: `bi-layers` (layered content icon)
   - Label: "Homepage Sections"
   - Panel ID: `homepage-sections`

2. **Added Panel Include** (line 311-314):
   - Includes the new homepage-sections panel
   - Panel ID: `homepage-sections-panel`
   - Hidden by default (shows when nav item clicked)

**Integration Points**:
- Seamlessly integrated with existing panels (Site Identity, Colors, Typography, Header, Footer)
- Uses same state management pattern as other panels
- Shares global `updatePreview()` function
- Participates in publish workflow

---

### 3. Controller Updates ✅
**Modified**: `app/Http/Controllers/CustomizerController.php`

#### A. Preview Method Enhanced (line 63-66)
**Added Settings Preview**:
```php
$activeTheme->settings_overrides = array_merge(
    $activeTheme->settings_overrides ?? [],
    $tempCustomizations['settings'] ?? []
);
```

**Impact**:
- Temporary section settings now apply during preview
- Users see section changes before publishing
- Session-based preview maintains safety

#### B. Publish Method Updated (line 118-160)
**Added Dual Format Support**:
```php
// Support both new format (colors, fonts, settings)
// and old format (*_overrides)
$colorOverrides = $request->input('colors') ?? $request->input('color_overrides');
$fontOverrides = $request->input('fonts') ?? $request->input('font_overrides');
$settingsOverrides = $request->input('settings') ?? $request->input('settings_overrides');
```

**Benefits**:
- Backward compatibility with legacy code
- Supports JavaScript state structure directly
- Cleaner data flow from frontend to backend

#### C. Preview Rendering Updated (line 82-84)
**Added Homepage Detection**:
```php
$isHomePage = $homepage && $homepage->is_home;
$components = $activeTheme->getActiveComponents($isHomePage);
```

**Impact**:
- Sections filter/reorder only on homepage
- Other pages remain unaffected
- Preview accurately reflects final output

---

### 4. Theme Rendering Logic Updated ✅

#### A. WebsiteTheme Model Enhanced
**Modified**: `app/Models/WebsiteTheme.php` (line 150-214)

**New Method Signature**:
```php
public function getActiveComponents($filterBySectionSettings = false)
```

**Added Functionality**:

1. **Section Filtering Logic** (line 159-167):
```php
if ($filterBySectionSettings && $baseComponent->type === 'section' && !empty($homepageSectionSettings)) {
    $sectionSetting = collect($homepageSectionSettings)->firstWhere('id', $baseComponent->id);

    if ($sectionSetting && !($sectionSetting['enabled'] ?? true)) {
        continue; // Skip disabled sections
    }
}
```

2. **Component ID Tracking** (line 171):
```php
'component_id' => $baseComponent->id,  // Track theme component ID
```

3. **Section Reordering Logic** (line 191-211):
```php
if ($filterBySectionSettings && !empty($homepageSectionSettings) && isset($components['section'])) {
    $orderedSections = [];
    $sortedSettings = collect($homepageSectionSettings)->sortBy('order')->values();

    foreach ($sortedSettings as $setting) {
        foreach ($components['section'] as $section) {
            if ($section['component_id'] == $setting['id']) {
                $orderedSections[] = $section;
                break;
            }
        }
    }

    if (!empty($orderedSections)) {
        $components['section'] = $orderedSections;
    }
}
```

**Benefits**:
- Sections display in user-defined order
- Disabled sections completely hidden
- Non-section components (header, footer) unaffected
- Maintains compatibility with non-homepage pages

#### B. PublicController Updated
**Modified**: `app/Http/Controllers/PublicController.php` (line 323-324)

**Change**:
```php
// Filter by section settings if this is the homepage
$components = $website->activeTheme->getActiveComponents($isHomePage);
```

**Impact**:
- Homepage respects section settings
- Other pages render all sections
- Consistent behavior across live site

## 🔍 Technical Implementation

### Data Storage Structure

**Database Field**: `website_themes.settings_overrides`

**Stored as JSON**:
```json
{
    "homepage_sections": [
        {
            "id": 1,
            "slug": "hero-slider",
            "enabled": true,
            "order": 0
        },
        {
            "id": 3,
            "slug": "features-section",
            "enabled": true,
            "order": 1
        },
        {
            "id": 4,
            "slug": "about-section",
            "enabled": false,
            "order": 2
        }
    ],
    "header": { ... },
    "footer": { ... }
}
```

### Session-Based Preview

**Flow**:
1. User makes changes in customizer
2. JavaScript updates `customizerState.settings.homepage_sections`
3. AJAX call to `/customizer/update` stores in session:
   ```php
   session(['temp_customizations_' . $website->id => $customizations]);
   ```
4. Preview iframe reloads with query parameter
5. CustomizerController applies temp settings:
   ```php
   $activeTheme->settings_overrides = array_merge(
       $activeTheme->settings_overrides ?? [],
       $tempCustomizations['settings'] ?? []
   );
   ```
6. Sections filter/reorder based on temp settings
7. User sees changes without affecting live site

**On Publish**:
1. Settings move from session to database
2. Session cleared
3. Live site uses database settings

    // Find and add section in order
}
```

### 3. Real-Time JavaScript Updates
```javascript
// Automatically update settings when drag ends
onEnd: function(evt) {
    updateSectionSettings();
}

// Debounced preview refresh
function updateSectionSettings() {
    // ... update customizerState
    updatePreview(); // 500ms debounced
}
```

### 4. Dual Format Support

// Supports both JavaScript state format and legacy format
$settingsOverrides = $request->input('settings') ?? $request->input('settings_overrides');
```
