## Code Examples for Developers

### Get Published Sliders
```php
$sliders = Slider::published()->get();
// Returns only published sliders, ordered by order field
```

### Get All Sliders
```php
$sliders = Slider::orderBy('order', 'asc')->get();
// Get all sliders regardless of status
```

### Display Slider Image
```blade
@foreach(Slider::published()->get() as $slider)
    <img src="{{ $slider->getImageUrl() }}" 
         alt="{{ $slider->title }}">
@endforeach
```

### Check Image Type
```php
if ($slider->isUploadedImage()) {
    $size = $slider->getFormattedFileSize();  // "2.45 MB"
    $filename = $slider->image_filename;      // "slider1.jpg"
} else {
    $url = $slider->image_path;               // "https://..."
}
```

### Create Slider Programmatically
```php
$sliderService = app(\App\Services\SliderService::class);

// Upload method
$slider = $sliderService->create([
    'title' => 'My Slider',
    'image_source' => 'upload',
    'image_file' => $uploadedFile,
    'status' => 'published',
    'order' => 0
]);

// URL method

    'title' => 'External Slider',
    'image_source' => 'url',

    'status' => 'published',

## Frontend Display Examples

### Basic Hero Section
```blade
<div class="hero">
    @foreach(Slider::published()->get() as $slider)
        <div class="slide">
            <img src="{{ $slider->getImageUrl() }}" 
                 alt="{{ $slider->title }}"
                 class="hero-image">
            <h1>{{ $slider->title }}</h1>
        </div>
    @endforeach
</div>
```

### With Pagination
```blade
<div class="sliders">
    @foreach($sliders as $slider)
        <div class="slider-card">
            <img src="{{ $slider->getImageUrl() }}">
            <p>{{ $slider->title }}</p>
        </div>
    @endforeach
</div>

{{ $sliders->links() }}
```

### With Lazy Loading
```blade
@foreach(Slider::published()->get() as $slider)

         loading="lazy">
@endforeach
```

## Troubleshooting

### Images not showing?
1. Check storage link: `ls -la public/storage`
2. Run: `php artisan storage:link`
3. Clear cache: `php artisan cache:clear`

### Upload failing?
1. Check file permissions: `chmod -R 775 storage/`
2. Check max upload size in php.ini
3. Verify folder exists: `mkdir -p storage/app/public/sliders`

### Styles look wrong?
1. Clear view cache: `php artisan view:clear`
2. Clear config: `php artisan config:clear`
3. Reload browser (Ctrl+Shift+R)

### Old data not showing?
1. Run migration: `php artisan migrate`
2. Migrate old data:
   ```sql
   UPDATE sliders SET image_source = 'url', image_path = image_url
   WHERE image_url IS NOT NULL;
   ```

## Best Practices

### File Upload
- ✅ Keep images under 5MB when possible
- ✅ Use compressed formats (WebP recommended)
- ✅ Resize to 1920×400 before uploading
- ✅ Use descriptive filenames

### URLs
- ✅ Use HTTPS URLs only
- ✅ Avoid slow-loading images
- ✅ Check URLs periodically
- ✅ Use permanent URLs (not temporary links)

### Management
- ✅ Keep order values logical (0, 1, 2...)
- ✅ Archive old sliders instead of deleting
- ✅ Use draft for testing before publishing
- ✅ Review published sliders weekly

### Performance
- ✅ Limit to <20 published sliders
- ✅ Use lazy loading on frontend
- ✅ Optimize images
- ✅ Monitor storage space
