Creating custom request handler

This bundle comes with HttpFoundation request handler built-in. However, it's common to create custom request handlers to solve specific purposes in your projects.

To create a custom request handler, create a class that implements RequestHandlerInterface:

// src/DataTable/Request/ExcelRequestHandler.php
namespace App\DataTable\Request;

use Kreyu\Bundle\DataTableBundle\Request\RequestHandlerInterface;
use Kreyu\Bundle\DataTableBundle\Sorting\SortingData;
use Kreyu\Bundle\DataTableBundle\Sorting\SortingField;

class ExcelRequestHandler implements RequestHandlerInterface
{
    public function handle(DataTableInterface $dataTable, mixed $request = null): void
    {
        $sortingData = new SortingData([
            new SortingField($request['name'], $request['direction']),
        ]);

        $dataTable->sort($sortingData); 
    }
}

The interface only contains a single handle() method, will all the necessary data: a data table and a request object.

From here, for example, you can call sort(), paginate(), personalize() and filter() methods with data extracted from the request object.
