How to work with the Search Form

The grid component allows to filter its content, to manage the filtering you will need to define the following elements:

  • GridDefinition::getFilters
  • Filters class
  • Controllers:
    • Search action
    • List action
    • Reset filter action

Add Filters into GridDefinition

You should use AbstractGridDefinitionFactory as a parent class, and define a const GRID_ID which will be used as a key to persist the Filters.

<?php
final class ManufacturerGridDefinitionFactory extends AbstractGridDefinitionFactory
{
    const GRID_ID = 'manufacturer';

    /**
     * {@inheritdoc}
     */
    protected function getId()
    {
        return self::GRID_ID;
    }

    ...
    /**
    * {@inheritdoc}
    */
    protected function getFilters()
    {
        return (new FilterCollection())
            ->add((new Filter('id_manufacturer', TextType::class))
                ->setTypeOptions([
                    'required' => false,
                    'attr' => [
                        'placeholder' => $this->trans('Search ID', [], 'Admin.Actions'),
                    ],
                ])
                ->setAssociatedColumn('id_manufacturer')
            )
            ->add((new Filter('name', TextType::class))
                ->setTypeOptions([
                    'required' => false,
                    'attr' => [
                        'placeholder' => $this->trans('Search name', [], 'Admin.Actions'),
                    ],
                ])
                ->setAssociatedColumn('name')
            )
            ->add((new Filter('active', YesAndNoChoiceType::class))
                ->setAssociatedColumn('active')
            )
            ->add((new Filter('actions', SearchAndResetType::class))
                ->setAssociatedColumn('actions')
                ->setTypeOptions([
                    'reset_route' => 'admin_common_reset_search_by_filter_id',
                    'reset_route_params' => [
                        'filterId' => self::GRID_ID,
                    ],
                    'redirect_route' => 'admin_manufacturers_index',
                ])
            )
        ;
    }
    ...
}

The filters types

The filters collection allows you to define all the available filters (which will match your grid columns). You can define a specific type depending on the column. You can basically use any Symfony form type (including your custom ones) and PrestaShop provides a few filter types that might be useful to you.

Filterable grid definition

Starting the 1.7.7 we made it even easier, you can use the AbstractFilterableGridDefinitionFactory. This will allow you use the common search controller.

<?php
final class AddressGridDefinitionFactory extends AbstractFilterableGridDefinitionFactory
{
    const GRID_ID = 'address';

    /**
     * {@inheritdoc}
     */
    protected function getId()
    {
        return self::GRID_ID;
    }
    ...
}

Filters class

You need to define a Filters class linked to your Grid, it will allow you to define the default filters and sorting values. It will also make your list action simpler as PrestaShop provides a parameter resolver responsible of automatically create and fill a Filters object.

<?php
use PrestaShop\PrestaShop\Core\Grid\Definition\Factory\ManufacturerGridDefinitionFactory;
use PrestaShop\PrestaShop\Core\Search\Filters;

/**
 * Class ManufacturerFilters is responsible for providing filter values for manufacturer grid.
 */
final class ManufacturerFilters extends Filters
{
    /** @var string */
    protected $filterId = ManufacturerGridDefinitionFactory::GRID_ID;

    /**
     * {@inheritdoc}
     */
    public static function getDefaults()
    {
        return [
            'limit' => 10,
            'offset' => 0,
            'orderBy' => 'name',
            'sortOrder' => 'asc',
            'filters' => [],
        ];
    }
}

Controller actions

The Grid filtering workflow is divided into three actions:

  • search action: it parses the filters from the POST request, then redirects to the list action
  • list action: it parses the filters from GET request, persists them into database and finally renders the grid
  • reset action: it cleans the persisted filters and reset to the default ones
In this tutorial we assume the search and list actions have the same url, thus we don’t need to specify the search route in the form action. Search manages the POST request and list the GET request.
Most of the time you will use the default form factory when you configure your grid factory which is usually enough. However if you need to change the form action route or perform any other advanced management you might need to create your custom form factory.

Search action

Custom search controller

You can use the ResponseBuilder service to easily create the search response, it only needs four arguments as input:

  • the definition factory
  • the request
  • the filter ID
  • the list route for redirection
<?php
use PrestaShop\PrestaShop\Core\Grid\Definition\Factory\ManufacturerGridDefinitionFactory;
use PrestaShopBundle\Service\Grid\ResponseBuilder;
use PrestaShopBundle\Security\Annotation\AdminSecurity;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\RedirectResponse;

class ManufacturerController extends FrameworkBundleAdminController
{
    ...
    /**
     * Provides filters functionality
     *
     * @AdminSecurity("is_granted('read', request.get('_legacy_controller'))")
     *
     * @param Request $request
     *
     * @return RedirectResponse
     */
    public function searchAction(Request $request)
    {
        /** @var ResponseBuilder $responseBuilder */
        $responseBuilder = $this->get('prestashop.bundle.grid.response_builder');

        return $responseBuilder->buildSearchResponse(
            $this->get('prestashop.core.grid.definition.factory.manufacturer'),
            $request,
            ManufacturerGridDefinitionFactory::GRID_ID,
            'admin_manufacturers_index'
        );
    }
    ...
}
# your-module/config/routes.yml
admin_manufacturers_search:
  path: /
  methods: POST
  defaults:
    _controller: 'PrestaShopBundle:Admin/Sell/Catalog/Manufacturer:search'
    _legacy_controller: AdminManufacturers
    _legacy_link: AdminManufacturers:submitFiltermanufacturer

Common search controller

As this controller is almost always the same, starting 1.7.7, we introduced a common controller. So all you need to do is define the routing:

# your-module/config/routes.yml
admin_addresses_search:
  path: /
  methods: [POST]
  defaults:
    _controller: PrestaShopBundle:Admin\Common:searchGrid
    gridDefinitionFactoryServiceId: prestashop.core.grid.definition.factory.address
    redirectRoute: admin_addresses_index
    _legacy_controller: AdminAddresses
    _legacy_link: AdminAddresses:submitFilteraddress

List action

Thanks to the internal parameter resolver you can directly use your Filters class as an argument in the controller. It then automatically:

  • parses the potential parameters in the query and fills them into the Filters argument
  • matches thanks to the class the filters from the database and fetch them if present
  • persists the filters in the database
<?php
class ManufacturerController extends FrameworkBundleAdminController
{
    ...
    /**
     * Show manufacturers listing page.
     *
     * @AdminSecurity("is_granted('read', request.get('_legacy_controller'))")
     *
     * @param Request $request
     * @param ManufacturerFilters $manufacturerFilters
     *
     * @return Response
     */
    public function indexAction(
        Request $request,
        ManufacturerFilters $manufacturerFilters
    ) {
        $manufacturerGridFactory = $this->get('prestashop.core.grid.grid_factory.manufacturer');
        $manufacturerGrid = $manufacturerGridFactory->getGrid($manufacturerFilters);

        return $this->render('@PrestaShop/Admin/Sell/Catalog/Manufacturer/index.html.twig', [
            'enableSidebar' => true,
            'help_link' => $this->generateSidebarLink($request->attributes->get('_legacy_controller')),
            'manufacturerGrid' => $this->presentGrid($manufacturerGrid),
        ]);
    }
    ...
}

Reset action

This action resets the persisted filters and your grid filtering/sorting. This action is the same for nearly all grids so PrestaShop provides a common controller to manage it, and you actually already set it via the grid definition.

It is defined in the SearchAndResetType options, it uses admin_common_reset_search_by_filter_id and only needs the filter id to identify the filters to clear, and a redirection route.

<?php
    ...
            ->add((new Filter('actions', SearchAndResetType::class))
                ->setAssociatedColumn('actions')
                ->setTypeOptions([
                    'reset_route' => 'admin_common_reset_search_by_filter_id',
                    'reset_route_params' => [
                        'filterId' => self::GRID_ID,
                    ],
                    'redirect_route' => 'admin_manufacturers_index',
                ])
            )
    ...

Search form in 1.7.5

In the 1.7.5 version, first one that integrated the grid component, the system was a bit different and used controller/action to identify the filters. It had a few drawbacks and was abandoned in favor of a unique id but in case you need it here is how to work with search form in 1.7.5.
