# NewExcelFile injections

Following the Laravel 5.0 philosophy with its new awesome FormRequest injections, we introduce you NewExcelFile injections.

## NewExcelFile class

This NewExcelFile is a wrapper for a new Excel file. Inside the `getFilename()` you can declare the wanted filename.

```
class UserListExport extends \Maatwebsite\Excel\Files\NewExcelFile {

    public function getFilename()
    {
        return 'filename';
    }
}
```

## Usage

You can inject these NewExcelFiles inside the \_\_constructor or inside the method (when using Laravel 5.0), in e.g. the controller.

```
class ExampleController extends Controller {

    public function exportUserList(UserListExport $export)
    {
        // work on the export
        return $export->sheet('sheetName', function($sheet)
        {

        })->export('xls');
    }

}
```

## Export Handlers

To decouple your Excel-export code completely from the controller, you can use the export handlers.

```
class ExampleController extends Controller {

    public function exportUserList(UserListExport $export)
    {
        // Handle the export
        $export->handleExport();
    }

}
```

The `handleExport()` method will dynamically call a handler class which is your class name appended with `Handler`

```
class UserListExportHandler implements \Maatwebsite\Excel\Files\ExportHandler {

    public function handle(UserListExport $export)
    {
        // work on the export
        return $export->sheet('sheetName', function($sheet)
        {

        })->export('xls');
    }

}
```
