The Grid component


The Grid component provides tools that allow you to build, manage and display your data tables. The most important parts of Grid component are:

  • Grid definition - defines structural information about a grid.
  • Grid data - stores data for a grid.
  • Search criteria - stores sorting, pagination and filters data for a grid.

Grid definition

This is the most fundamental part of the Grid component. A Grid definition stores structural information about your Grid that defines:

  • Id - unique id for Grid identification. It is used to dispatch hooks and identify Grid in other parts of the application.
  • Name - human readable name, it is recommended to make it translatable.
  • Columns - definition of columns that your Grid table has.
  • Filters - definition of filters that are supported by Grid.
  • Grid actions - actions that apply to a whole grid. It is common to have “Export”, “Import”, “Show SQL query” and similar grid actions.
  • Bulk actions - actions that can be applied to multiple records in the Grid. It is common to have “Delete selected”, “Enable selected” and similar bulk actions.

Creating Grid Definition

You don’t have to create the Grid Definition by yourself but instead rely on a PrestaShop\PrestaShop\Core\Grid\Definition\Factory\GridDefinitionFactoryInterface. PrestaShop already provides you with an abstract factory implementation PrestaShop\PrestaShop\Core\Grid\Definition\Factory\AbstractGridDefinitionFactory that you can use to create Grid definitions.

When creating a Grid definition it is recommended to use PrestaShop\PrestaShop\Core\Grid\Definition\Factory\AbstractGridDefinitionFactory as it allows you to define your structure, but takes care of the definition creation.

To create a new grid definition, we will use AbstractGridDefinitionFactory.

namespace PrestaShop\PrestaShop\Core\Grid\Definition\Factory;

use PrestaShop\PrestaShop\Core\Grid\Definition\Factory\AbstractGridDefinitionFactory;
use PrestaShop\PrestaShop\Core\Grid\Column\ColumnCollection;
use PrestaShop\PrestaShop\Core\Grid\Column\Type\DataColumn;

final class ProductGridDefinitionFactory extends AbstractGridDefinitionFactory
    protected function getId()
        return 'products';

    protected function getName()
        return $this->trans('Products', [], 'Admin.Advparameters.Feature');

    protected function getColumns()
        return (new ColumnCollection())
            ->add((new DataColumn('id_product'))
                ->setName($this->trans('ID', [], 'Admin.Global'))
                    'field' => 'id_product',
            ->add((new DataColumn('reference'))
                ->setName($this->trans('Reference', [], 'Admin.Advparameters.Feature'))
                    'field' => 'reference',
            ->add((new DataColumn('name'))
                ->setName($this->trans('Name', [], 'Admin.Advparameters.Feature'))
                    'field' => 'name',

We have just created a basic Grid Definition factory in which we defined our Grid’s id products, translatable name Products and 3 data columns.

It is recommended to keep your name translatable. To make that easy, AbstractGridDefinitionFactory provides access to the translator via the trans() method.

Finally, register your Grid definition factory as a service.

    class: 'PrestaShop\PrestaShop\Core\Grid\Definition\Factory\ProductGridDefinitionFactory'
    parent: 'prestashop.core.grid.definition.factory.abstract_grid_definition'
    public: true

Most of the time you won’t be creating Grid Definitions by yourself but delegating this task to other services, but in case you need to create a Grid Definition by hand, here’s how you can do that.

$productsGridDefinitionFactory = $container->get('prestashop.core.grid.definition.factory.product_grid_definition_factory');
$productsGridDefinition = $productsGridDefinitionFactory->getDefinition();

// you can access all information that was defined
$productsGridDefinition->getColumns(); // collection of defined columns
$productsGridDefinition->getName(); // "Products"
$productsGridDefinition->getId(); // "products"

Search Criteria

In the Grid component, Search Criteria is used for Grid’s data sorting, paginating & filtering. Search Criteria can be loaded from the database, URL query or anywhere else.

The Grid component itself does not manage Search Criteria but instead it provides an interface for it. In PrestaShop, the Filters component is used to resolve Search Criteria for a Grid.
Search Criteria is immutable. This means that once a Search Criteria object is created it cannot be changed.

Creating Search Criteria

Even though most of the time Search Criteria will be created using the Filters component, you can still create it manually. Grid provides a simple implementation for it.

use PrestaShop\PrestaShop\Core\Grid\Search\SearchCriteria;

$filters = [
    'id_product' => 4,
    'name' => 'mug',

$searchCriteria = new SearchCriteria(

$searchCriteria->getFilters();  // $filters array
$searchCriteria->getOrderBy();  // "id_product"
$searchCriteria->getOrderWay(); // "asc"
$searchCriteria->getOffset();   // 0
$searchCriteria->getLimit();    // 10
The class PrestaShop\PrestaShop\Core\Grid\Search\SearchCriteria is only available since 1.7.6

When creating Search Criteria you can skip some or all of its data. If you set both orderWay and orderBy to null it will disable sorting. If you set both offset and limit to null it will disable pagination.

use PrestaShop\PrestaShop\Core\Grid\Search\SearchCriteria;

// sorting, pagination and filtering are disabled with this search criteria
$emptySearchCriteria = new SearchCriteria();

// only pagination is set
// that means sorting (and filters as it's an empty array) will be disabled for search criteria
$emptySortingSearchCriteria = new SearchCriteria(

Grid Data

The final part of the Grid component is data. Grid Data is stored in PrestaShop\PrestaShop\Core\Grid\Data\GridData.

Creating Grid Data

The Grid component does not create Grid Data directly but instead relies on PrestaShop\PrestaShop\Core\Grid\Data\Factory\GridDataFactoryInterface. PrestaShop provides you with a DoctrineGridDataFactory implementation out of the box which supports retrieving data from a MySQL database using Doctrine. However, if you need to load data from a REST API, Elasticsearch or any other data store, you can implement your own Grid Data factory.

We will be using DoctrineGridDataFactory to create data for our Grid. When using DoctrineGridDataFactory you have to implement DoctrineQueryBuilderInterface which will be used by the data factory to build Doctrine queries.

When implementing DoctrineQueryBuilderInterface it is recommended to use PrestaShop\PrestaShop\Core\Grid\Query\AbstractDoctrineQueryBuilder as it provides access to the Doctrine Connection and database tables prefix.
use PrestaShop\PrestaShop\Core\Grid\Query\AbstractDoctrineQueryBuilder;
use Doctrine\DBAL\Connection;
use PrestaShop\PrestaShop\Core\Grid\Search\SearchCriteriaInterface;

final class ProductQueryBuilder extends AbstractDoctrineQueryBuilder
     * @var int
    private $contextLangId;

     * @var int
    private $contextShopId;

     * @param Connection $connection
     * @param string $dbPrefix
     * @param int $contextLangId
     * @param int $contextShopId
    public function __construct(Connection $connection, $dbPrefix, $contextLangId, $contextShopId)
        parent::__construct($connection, $dbPrefix);

        $this->contextLangId = $contextLangId;
        $this->contextShopId = $contextShopId;

    // Get Search query builder returns a QueryBuilder that is used to fetch filtered, sorted and paginated data from the database.
    // This query builder is also used to get the SQL query that was executed.
    public function getSearchQueryBuilder(SearchCriteriaInterface $searchCriteria)
        $qb = $this->getBaseQuery();
        $qb->select('p.id_product, p.reference, pl.name')
        foreach ($searchCriteria->getFilters() as $filterName => $filterValue) {
            if ('id_product' === $filterName) {
                $qb->andWhere("p.id_product = :$filterName");
                $qb->setParameter($filterName, $filterValue);


            $qb->andWhere("$filterName LIKE :$filterName");
            $qb->setParameter($filterName, '%'.$filterValue.'%');

        return $qb;
    // Get Count query builder that is used to get the total count of all records (products)
    public function getCountQueryBuilder(SearchCriteriaInterface $searchCriteria)
        $qb = $this->getBaseQuery();

        return $qb;
    // Base query can be used for both Search and Count query builders
    private function getBaseQuery()
        return $this->connection
            ->from($this->dbPrefix.'product', 'p')
                'p.id_product = pl.id_product AND pl.id_lang = :context_lang_id AND pl.id_shop = :context_shop_id'
            ->setParameter('context_lang_id', $this->contextLangId)
            ->setParameter('context_shop_id', $this->contextShopId)

Once the Query builder is done, the last step is to register it as a service and configure your DoctrineGridDataFactory to use it.

# Register ProductQueryBuilder
    class: 'PrestaShop\PrestaShop\Core\Grid\Query\ProductQueryBuilder'
    parent: 'prestashop.core.grid.abstract_query_builder'
        - "@=service('prestashop.adapter.legacy.context').getContext().language.id"
        - "@=service('prestashop.adapter.legacy.context').getContext().shop.id"
    public: true
# Configure our Grid Data factory to use the query builder that we registered above
    class: 'PrestaShop\PrestaShop\Core\Grid\Data\Factory\DoctrineGridDataFactory'
        - '@prestashop.core.grid.query.product_query_builder' # service id of our query builder
        - '@prestashop.core.hook.dispatcher' # every doctrine query builder needs the hook dispatcher
        - '@prestashop.core.grid.query.doctrine_query_parser' # parser to get the raw SQL query
        - 'products' # this should match your grid id, in our case it's "products"

That’s it! Now we can use our Grid Data factory together with Search Criteria to get sorted, paginated and filtered data for our Grid.

$searchCriteria = ...

/** PrestaShop\PrestaShop\Core\Grid\Data\Factory\GridDataFactoryInterface $productGridDataFactory */
$productGridDataFactory = $container->get('prestashop.core.grid.data.factory.product_data_factory');
$productGridData = $productDataFactory->getData($searchCriteria);

$productGridData->getRecords(); // returns RecordCollection that contains products data
$productGridData->getRecordsTotal(); // returns the total count of products
$productGridData->getQuery(); // get the last executed query that was used to get RecordCollection

Working with Grid

We already know how to create and use Grid Definitions and Grid Data factories. Now it’s time to combine those services to create our Grid!

Configuring Grid factory

As always, you should not create Grid by hand, PrestaShop already comes with PrestaShop\PrestaShop\Core\Grid\GridFactory whose primary job is to create a Grid.

It is recommended to use the PrestaShop\PrestaShop\Core\Grid\GridFactory to create Grids although you may need to create your own Grid factory in some rare cases.

Let’s configure a GridFactory with our Grid Definition and Grid Data factory.

# Configure Grid factory to use services we have implemented
    class: 'PrestaShop\PrestaShop\Core\Grid\GridFactory'
        - '@prestashop.core.grid.definition.factory.product_grid_definition_factory' # our definition factory
        - '@prestashop.core.grid.data.factory.product_data_factory'              # our data factory
        - '@prestashop.core.grid.filter.form_factory'                            # core service needed by grid factory
        - '@prestashop.core.hook.dispatcher'                                     # core service needed by grid factory

And we are done! Let’s see how to use it and render it in the page.

Rendering Grid

In Back Office controllers, you can use the Grid Factory to create a Grid and render it.

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;

class ProductController extends FrameworkBundleAdminController
     * @return Response
    public function indexAction()
        $searchCriteria = ...
        $productGridFactory = $this->get('prestashop.core.grid.product_grid_factory');
        $productGrid = $productGridFactory->getGrid($searchCriteria);
        return $this->render('@PrestaShop/Admin/Product/products.html.twig', [
            // $this->presentGrid() is a helper method provided by FrameworkBundleAdminController
            'productsGrid' => $this->presentGrid($productGrid),

To see the Grid in your page you have to include its template, which is provided by PrestaShop.

{# @PrestaShop/Admin/Product/products.html.twig #}

{% include '@PrestaShop/Admin/Common/Grid/grid_panel.html.twig' with {'grid': productsGrid} %}

It is possible to include the provided template and modify some parts of it, or you can create your own template to render the Grid.
