The Custom Fields plugin provides robust import and export capabilities for handling custom field data. This documentation explains how to integrate custom fields with Filament’s import/export actions.

​
Import Implementation

namespace App\Filament\Imports;

use App\Models\Product;
use Filament\Actions\Imports\ImportColumn;
use Filament\Actions\Imports\Importer;
use Relaticle\CustomFields\Facades\CustomFields;

class ProductImporter extends Importer
{
    protected static ?string $model = Product::class;
    
    // Simplest implementation: Add columns in getColumns()
    public static function getColumns(): array
    {
        return [
            // Regular columns
            ImportColumn::make('name')->requiredMapping()->rules(['required']),
            ImportColumn::make('price')->numeric(),
            
            // Add all custom fields
            ...CustomFields::importer()->forModel(self::getModel())->columns(),
        ];
    }
    
    // After saving model, save custom fields
    protected function afterSave(): void
    {
        CustomFields::importer()->forModel($this->record)->saveValues();
    }
}

Export Implementation

namespace App\Filament\Exports;

use App\Models\Product;
use Filament\Actions\Exports\ExportColumn;
use Filament\Actions\Exports\Exporter;
use Relaticle\CustomFields\Facades\CustomFields;

class ProductExporter extends Exporter
{
    protected static ?string $model = Product::class;

    // Simply add your columns and spread in the custom fields
    public static function getColumns(): array
    {
        return [
            ExportColumn::make('id'),
            ExportColumn::make('name'),
            ExportColumn::make('price'),
            
            // Add all custom fields
            ...CustomFields::exporter()->forModel(self::getModel())->columns(),
        ];
    }
}
