The grid component allows to filter its content, to manage the filtering you will need to define the following elements:
GridDefinition::getFiltersFilters classYou 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 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.
This can be made even easier by using 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;
}
...
}
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' => [],
];
}
}
The Grid filtering workflow is divided into three actions:
You can use the ResponseBuilder service to easily create the search response, it only needs four arguments as input:
<?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
As this controller is almost always the same, 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
Thanks to the internal parameter resolver you can directly use your Filters class as an argument in the controller. It then automatically:
Filters argument<?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),
]);
}
...
}
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',
])
)
...
