🚀 Basic Usage

Understanding the Component

The GalleryMediaField is a custom Filament form component designed to browse and select one or more media items (images or videos) from a pre-existing gallery. It stores the IDs of the selected media, which are then used to create a many-to-many relationship between your primary model and the media models (Image, Video) provided by the gallery package.

Step 1: Add the Component to Your Form

Add GalleryMediaField to your Filament form schema. You must specify the mediaType and a name for the field that will hold the selected IDs.

use Devanderson\FilamentMediaGallery\Forms\Components\GalleryMediaField;

// In your Form schema
GalleryMediaField::make('videos_ids')
    ->mediaType('video')
    ->allowMultiple()
    ->columnSpanFull()

Field Configuration:

make('videos_ids'): Defines the field name that will hold an array of selected video IDs. Use a different name like images_ids for images.
mediaType('video'): Specifies the type of media to display in the gallery. Use 'image' for images.
allowMultiple(): Allows the user to select more than one item.

Step 2: Create Pivot Tables

A many-to-many relationship requires a "pivot" table to link your model with the media model. You need one pivot table for each media type you want to associate.

Image Pivot Table Migration

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    public function up(): void
    {
        Schema::create('project_image_image', function (Blueprint $table) {
            // Foreign key to your primary model's table
            $table->foreignId('project_image_id')->constrained()->onDelete('cascade');
            // Foreign key to the package's images table
            $table->foreignId('image_id')->constrained('images')->onDelete('cascade');
            // Primary key to prevent duplicates
            $table->primary(['project_image_id', 'image_id']);
        });
    }

    public function down(): void
    {
        Schema::dropIfExists('project_image_image');
    }
};

Video Pivot Table Migration

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    public function up(): void
    {
        Schema::create('project_image_video', function (Blueprint $table) {
            $table->foreignId('project_image_id')->constrained()->onDelete('cascade');
            $table->foreignId('video_id')->constrained('videos')->onDelete('cascade');
            $table->primary(['project_image_id', 'video_id']);
        });
    }

    public function down(): void
    {
        Schema::dropIfExists('project_image_video');
    }
};

Step 3: Define Model Relationships

In your primary model, define the belongsToMany relationship for each media type. You must specify the custom pivot table name as the second argument.

<?php

namespace App\Models;

use Devanderson\FilamentMediaGallery\Models\Image;
use Devanderson\FilamentMediaGallery\Models\Video;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\BelongsToMany;

class ProjectImage extends Model
{
    protected $fillable = [
        'title',
        'description',
        // ... other fields
    ];

    /**
     * Defines the many-to-many relationship with the Image model.
     * The second argument is the name of our pivot table.
     */
    public function images(): BelongsToMany
    {
        return $this->belongsToMany(Image::class, 'project_image_image');
    }

    /**
     * Defines the many-to-many relationship with the Video model.
     * The second argument is the name of our pivot table.
     */
    public function videos(): BelongsToMany
    {
        return $this->belongsToMany(Video::class, 'project_image_video');
    }
}

Step 4: Integrate with Filament Resource Pages

To make the component work properly, you need to add logic to your Filament CreateRecord and EditRecord pages to handle saving and loading the relationship data.

Using the ProcessUploadGallery Trait

The package provides a convenient trait that handles all the synchronization logic:

CreateRecord Page:

<?php

namespace App\Filament\Resources\ProjectImageResource\Pages;

use App\Filament\Resources\ProjectImageResource;
use Filament\Resources\Pages\CreateRecord;
use Devanderson\FilamentMediaGallery\Traits\ProcessUploadGallery;

class CreateProjectImage extends CreateRecord
{
    use ProcessUploadGallery;

    protected static string $resource = ProjectImageResource::class;
}

EditRecord Page:

<?php

namespace App\Filament\Resources\ProjectImageResource\Pages;

use App\Filament\Resources\ProjectImageResource;
use Filament\Resources\Pages\EditRecord;
use Devanderson\FilamentMediaGallery\Traits\ProcessUploadGallery;

class EditProjectImage extends EditRecord
{
    use ProcessUploadGallery;

    protected static string $resource = ProjectImageResource::class;

    /**
     * Load existing relationship IDs into form fields before filling the form
     */
    protected function mutateFormDataBeforeFill(array $data): array
    {
        // Load images IDs
        $data['images_ids'] = $this->record->images()->pluck('images.id')->toArray();
        
        // Load videos IDs
        $data['videos_ids'] = $this->record->videos()->pluck('videos.id')->toArray();

        return $data;
    }
}

What the Trait Does:

afterCreate hook: Synchronizes the selected media IDs with the model relationships after creating a new record
afterSave hook: Synchronizes the selected media IDs when editing an existing record

Complete Form Example

<?php

namespace App\Filament\Resources\ProjectImageResource;

use Filament\Forms;
use Filament\Forms\Form;
use Devanderson\FilamentMediaGallery\Forms\Components\GalleryMediaField;

class ProjectImageForm
{
    public static function form(Form $form): Form
    {
        return $form
            ->schema([
                Forms\Components\TextInput::make('title')
                    ->required()
                    ->maxLength(255),

                Forms\Components\Textarea::make('description')
                    ->rows(3)
                    ->columnSpanFull(),

                // Gallery field for images
                GalleryMediaField::make('images_ids')
                    ->label('Gallery Images')
                    ->mediaType('image')
                    ->allowMultiple()
                    ->columnSpanFull(),

                // Gallery field for videos
                GalleryMediaField::make('videos_ids')
                    ->label('Gallery Videos')
                    ->mediaType('video')
                    ->allowMultiple()
                    ->columnSpanFull(),
            ]);
    }
}

⚙️ Configuration

The config/filament-media-gallery.php file offers various options:

return [
    // Storage disk
    'disk' => env('MEDIA_GALLERY_DISK', 'public'),

    // Storage path
    'path' => env('MEDIA_GALLERY_PATH', 'gallery'),

    // Image settings
    'image' => [
        'allowed_extensions' => ['jpg', 'jpeg', 'png', 'gif', 'webp'],
        'max_size' => 10240, // KB
        'editor' => [
            'enabled' => true,
            'aspect_ratios' => ['16:9', '4:3', '1:1', '9:16'],
        ],
    ],

    // Video settings
    'video' => [
        'allowed_extensions' => ['mp4', 'webm', 'ogg'],
        'max_size' => 102400, // KB

        'allow_multiple' => true,
        'max_items' => null,
    ],
];

🎬 FFmpeg Setup (Video Thumbnails)

To enable automatic thumbnail generation for videos, install FFmpeg:

Ubuntu/Debian

sudo apt-get install ffmpeg

macOS

brew install ffmpeg

Windows

Download from: https://ffmpeg.org/download.html

Configure in .env

FFMPEG_PATH=/usr/bin/ffmpeg
FFPROBE_PATH=/usr/bin/ffprobe

⚠️ Important Notes

Modal Forms Limitation

This implementation has been designed for use in standard Filament CreateRecord and EditRecord pages. It has not been tested within the context of modal forms (e.g., createOptionForm or editOptionForm inside a Select component). Using this component in modals may require additional adjustments to correctly handle the component's state and data flow.

Relationship Synchronization

The ProcessUploadGallery trait automatically handles the synchronization of media relationships. It:

Extracts field names ending with _ids from the form data
Converts field names to relationship names (e.g., videos_ids → videos)
Syncs the selected IDs with the corresponding relationship
Removes the temporary _ids fields from the saved data

🌍 Internationalization

The plugin includes translations for:

🇧🇷 Portuguese (pt_BR)
🇺🇸 English (en)

To add new translations:

php artisan vendor:publish --tag="filament-media-gallery-translations"

🧪 Testing

composer test
