# 🔧 Gallery & Logo Fixes - Complete Summary

## Issues Fixed

### ✅ 1. Gallery Upload/Display Error (White Page Issue)
**Problem:** Gallery pages showed white/blank page due to missing `media_type` column in database.

**Solution:** Added backward compatibility to handle databases with or without the `media_type` column.

**Files Modified:**
- `admin/gallery.php` - Added try-catch for database queries
- `gallery.php` - Added try-catch for public gallery display

**Technical Details:**
- Upload form now tries to insert with `media_type` column first
- If that fails (column doesn't exist), it falls back to inserting without it
- Display queries also handle missing column gracefully
- Default media_type set to 'image' for backward compatibility

### ✅ 2. Logo Background Removal
**Problem:** Logos had dark gradient backgrounds in multiple locations throughout the site.

**Locations Fixed:**

#### Login Page (`login.php`)
- **Before:** Logo in 48x48px dark gradient box
- **After:** Clean logo at 48px width, no background

#### Register Page (`register.php`)
- **Before:** Logo in 48x48px dark gradient box
- **After:** Clean logo at 48px width, no background

#### Admin Panel Sidebar (`admin/layout_top.php`)
- **Before:** Fire emoji 🔥 icon
- **After:** Actual logo image at 32px width

#### Already Fixed Previously:
- Navbar (100px, no background) ✅
- Footer (100px, no background) ✅
- Login/Register side panels (100px, no background) ✅

## Database Migration (OPTIONAL)

If you want full video support, run this SQL:

```sql
-- Add media_type column for video support
ALTER TABLE gallery 
ADD COLUMN IF NOT EXISTS media_type VARCHAR(10) DEFAULT 'image' AFTER image_url;

-- Set existing records to 'image' type
UPDATE gallery 
SET media_type = 'image' 
WHERE media_type IS NULL OR media_type = '';
```

**Note:** The code now works **with or without** this migration. The migration is only needed if you want to upload videos.

## What Changed Technically

### Gallery Backward Compatibility

**admin/gallery.php - Upload Handler:**
```php
// Now uses try-catch to handle missing column
try {
    $db->prepare("INSERT INTO gallery(...,media_type,...) VALUES(...)");
} catch (PDOException $e) {
    // Falls back to insert without media_type column
    $db->prepare("INSERT INTO gallery(...) VALUES(...)");
}
```

**admin/gallery.php - Display:**
```php
// Handles missing column during fetch
try {
    $items = $db->query("SELECT * FROM gallery...")->fetchAll();
} catch (PDOException $e) {
    $items = [];
}

// Adds default media_type if missing
foreach ($items as &$item) {
    if (!isset($item['media_type'])) {
        $item['media_type'] = 'image';
    }
}
```

**gallery.php - Public Display:**
```php
// Try with media_type column
try {
    $stmt = $db->query("SELECT ..., media_type, ... FROM gallery");
} catch (PDOException $e) {
    // Fallback without media_type
    $stmt = $db->query("SELECT ... FROM gallery");
    // Add default media_type to results
    foreach ($galleryItems as &$item) {
        $item['media_type'] = 'image';
    }
}
```

### Logo Background Removal

**login.php:**
```php
// BEFORE:
<div style="width:48px;height:48px;background:linear-gradient(135deg,#0f172a,#1e293b);...">
  <img src="..." style="width:24px;height:24px;">
</div>

// AFTER:
<div style="display:flex;align-items:center">
  <img src="..." style="width:48px;height:auto;">
</div>
```

**register.php:**
```php
// Same change as login.php
```

**admin/layout_top.php:**
```php
// BEFORE:
<a class="brand" href="...">
  <span style="font-size:1.2rem">🔥</span>
  <span>Stiles LPG Admin</span>
</a>

// AFTER:
<a class="brand" href="..." style="display:flex;align-items:center;gap:.6rem">
  <img src="/stile-lpg/backend/uploads/logo.png" style="width:32px;height:auto;">
  <span style="color:#fff;font-weight:800;font-size:1.05rem">Stiles LPG Admin</span>
</a>
```

## Browser Cache Clear

After deploying these changes, users should clear their browser cache or do a hard refresh:

- **Windows:** `Ctrl + Shift + R` or `Ctrl + F5`
- **Mac:** `Cmd + Shift + R`

## Support Notes

**If gallery still shows white page:**
1. Check PHP error logs: `/error_log` or server error logs
2. Enable error display temporarily in PHP to see exact error
3. Verify database connection is working
4. Check if `gallery` table exists in database

**If logos don't update:**
1. Clear browser cache (Ctrl+Shift+R)
2. Check if logo file exists at: `/stile-lpg/backend/uploads/logo.png`
3. Verify file permissions (should be readable by web server)

## Success Indicators

✅ Gallery public page loads without errors  
✅ Can upload images successfully
✅ No dark backgrounds around any logos
✅ Admin panel shows logo instead of fire emoji
✅ All logos display consistently across site
