Pagination

The data tables can be paginated, which is crucial when working with large data sources.

• Toggling the feature
• Saving applied pagination
• Default pagination
• Events

Toggling the feature

By default, the pagination feature is enabled for every data table. This can be configured thanks to the pagination_enabled option:

Globally (YAML)

kreyu_data_table:
  defaults:
    pagination:
      enabled: true

Globally (PHP)

use Symfony\Config\KreyuDataTableConfig;

return static function (KreyuDataTableConfig $config) {
    $defaults = $config->defaults();
    $defaults->pagination()->enabled(true);
};

For data table type

use Kreyu\Bundle\DataTableBundle\Type\AbstractDataTableType;
use Symfony\Component\OptionsResolver\OptionsResolver;

class ProductDataTableType extends AbstractDataTableType
{
    public function configureOptions(OptionsResolver $resolver): void
    {
        $resolver->setDefaults([
            'pagination_enabled' => true,
        ]);
    }
}

For specific data table

use App\DataTable\Type\ProductDataTableType;
use Kreyu\Bundle\DataTableBundle\DataTableFactoryAwareTrait;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;

class ProductController extends AbstractController
{
    use DataTableFactoryAwareTrait;
    
    public function index()
    {
        $dataTable = $this->createDataTable(
            type: ProductDataTableType::class, 
            query: $query,
            options: [
                'pagination_enabled' => true,
            ],
        );
    }
}

If you don't see the pagination controls, make sure your data table has enough records!

By default, every page contains 25 records. Built-in themes display pagination controls only when the data table contains more than one page. Also, remember that you can change the default pagination data, reducing the per-page limit.

Pagination is enabled, but changing the page does nothing?

Ensure that the handleRequest() method of the data table is called:

class ProductController
{
    public function index(Request $request)
    {
        $dataTable = $this->createDataTable(...);
        $dataTable->handleRequest($request); 
    }
}

Saving applied pagination

By default, the pagination feature persistence is disabled for every data table.

You can configure the persistence globally using the package configuration file, or its related options:

Globally (YAML)

kreyu_data_table:
  defaults:
    pagination:
      persistence_enabled: true
      # if persistence is enabled and symfony/cache is installed, null otherwise
      persistence_adapter: kreyu_data_table.sorting.persistence.adapter.cache
      # if persistence is enabled and symfony/security-bundle is installed, null otherwise
      persistence_subject_provider: kreyu_data_table.persistence.subject_provider.token_storage

Globally (PHP)

use Symfony\Config\KreyuDataTableConfig;

return static function (KreyuDataTableConfig $config) {
    $defaults = $config->defaults();
    $defaults->pagination()
        ->persistenceEnabled(true)
        // if persistence is enabled and symfony/cache is installed, null otherwise
        ->persistenceAdapter('kreyu_data_table.sorting.persistence.adapter.cache')
        // if persistence is enabled and symfony/security-bundle is installed, null otherwise
        ->persistenceSubjectProvider('kreyu_data_table.persistence.subject_provider.token_storage')
    ;
};

For data table type

use Kreyu\Bundle\DataTableBundle\Persistence\PersistenceAdapterInterface;
use Kreyu\Bundle\DataTableBundle\Persistence\PersistenceSubjectProviderInterface;
use Kreyu\Bundle\DataTableBundle\Type\AbstractDataTableType;
use Symfony\Component\OptionsResolver\OptionsResolver;

class ProductDataTableType extends AbstractDataTableType
{
    public function __construct(
        private PersistenceAdapterInterface $persistenceAdapter,
        private PersistenceSubjectProviderInterface $persistenceSubjectProvider,
    ) {
    }

    public function configureOptions(OptionsResolver $resolver): void
    {
        $resolver->setDefaults([
            'pagination_persistence_enabled' => true,
            'pagination_persistence_adapter' => $this->persistenceAdapter,
            'pagination_persistence_subject_provider' => $this->persistenceSubjectProvider,
        ]);
    }
}

For specific data table

use App\DataTable\Type\ProductDataTableType;
use Kreyu\Bundle\DataTableBundle\DataTableFactoryAwareTrait;
use Kreyu\Bundle\DataTableBundle\Persistence\PersistenceAdapterInterface;
use Kreyu\Bundle\DataTableBundle\Persistence\PersistenceSubjectProviderInterface;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;

class ProductController extends AbstractController
{
    use DataTableFactoryAwareTrait;
    
    public function __construct(
        private PersistenceAdapterInterface $persistenceAdapter,
        private PersistenceSubjectProviderInterface $persistenceSubjectProvider,
    ) {
    }
    
    public function index()
    {
        $dataTable = $this->createDataTable(
            type: ProductDataTableType::class, 
            query: $query,
            options: [
                'pagination_persistence_enabled' => true,
                'pagination_persistence_adapter' => $this->persistenceAdapter,
                'pagination_persistence_subject_provider' => $this->persistenceSubjectProvider,
            ],
        );
    }
}

Default pagination

The default pagination data can be overridden using the data table builder's setDefaultPaginationData() method:

use Kreyu\Bundle\DataTableBundle\DataTableBuilderInterface;
use Kreyu\Bundle\DataTableBundle\Type\AbstractDataTableType;
use Kreyu\Bundle\DataTableBundle\Pagination\PaginationData;

class ProductDataTableType extends AbstractDataTableType
{
    public function buildDataTable(DataTableBuilderInterface $builder, array $options): void
    {
        $builder->setDefaultPaginationData(new PaginationData(
            page: 1, 
            perPage: 25,
        ));
        
        // or by creating the pagination data from an array:
        $builder->setDefaultPaginationData(PaginationData::fromArray([
            'page' => 1, 
            'perPage' => 25,
        ]));
    }
}

Events

The following events are dispatched when paginate() method of the DataTableInterface is called:

PRE_PAGINATE

Dispatched before the pagination data is applied to the query. Can be used to modify the pagination data, e.g. to force specific page or a per-page limit.

See: DataTableEvents::PRE_PAGINATE

POST_PAGINATE

Dispatched after the pagination data is applied to the query and saved if the pagination persistence is enabled. Can be used to execute additional logic after the pagination is applied.

See: DataTableEvents::POST_PAGINATE

The dispatched events are instance of the DataTablePaginationEvent:

use Kreyu\Bundle\DataTableBundle\Event\DataTablePaginationEvent;

class DataTablePaginationListener
{
    public function __invoke(DataTablePaginationEvent $event): void
    {
        $dataTable = $event->getDataTable();
        $paginationData = $event->getPaginationData();
        
        // for example, modify the pagination data, then save it in the event
        $event->setPaginationData($paginationData); 
    }
}
