When to Use

Adding image gallery to models
Implementing single featured image
Setting up logo/favicon
Fixing image upload issues
Working with ImagesRelationManager
Image picker implementation

System Overview

Centralized Polymorphic:

Single images table for ALL entities
Polymorphic relationships
Order management (0 = cover)
Auto WebP conversion (85%)
Soft deletes with cleanup
CheckboxList picker (native Filament)

ImagesRelationManager

Auto-generated features:

Upload with drag-drop
Reorder with drag-drop
Set cover (order=0)
Edit alt text/title
Delete with confirmation
WebP auto-conversion

Generate:

php artisan make:filament-relation-manager ProductResource images file_path

ImageObserver

Auto-features:

Alt text from model name
Order auto-increment
Cover auto-set
Soft delete cleanup

class ImageObserver
{
    public function creating(Image $image): void
    {
        if (empty($image->alt_text) && $image->model) {
            $image->alt_text = $image->model->name ?? 'Image';
        }
        
        if ($image->order === null) {
            $max = Image::where('model_type', $image->model_type)
                ->where('model_id', $image->model_id)
                ->max('order');
            $image->order = ($max ?? -1) + 1;
        }
    }
}

WebP Conversion

Automatic on upload:

Original preserved
WebP created (85% quality)
Stored in storage/app/public/images/
Auto-served via intervention

Manual conversion:

$webpPath = Image::convertToWebP($originalPath);

Common Issues

Issue: Unique constraint violation on order

Solution:

// ImageObserver handles auto-increment
// Don't manually set order=0 for all images

Issue: Images not showing

Check:

Storage link: php artisan storage:link
Disk config: config/filesystems.php
Image path: Storage::url($image->file_path)

Issue: Multiple covers (order=0)

Solution:

// When setting new cover
Image::where('model_type', $type)
    ->where('model_id', $id)
    ->where('order', 0)
    ->update(['order' => 999]);  // Reset old cover

$newCover->update(['order' => 0]);
