README

The LexikFormFilterBundle, a historical bundle, is now renamed to SpiriitFormFilterBundle. The code remains unchanged; only the name and organization have changed on GitHub.

This Symfony bundle aims to provide classes to build some form types dedicated to filter an entity. Once you created your form type you will be able to update a doctrine query builder conditions from a form type.

The idea is:

1. Create a form type extending from Symfony\Component\Form\AbstractType as usual.
2. Add form fields by using provided filter types (e.g. use TextFilterType::class instead of a TextType::class type) (*).
3. Then call a service to build the query from the form instance and execute your query to get your result :).

(*): In fact you can use any type, but if you want to apply a filter by not using a XxxFilterType::class type you will have to create a custom listener class to apply the filter for this type.

Installation

================

The bundle can be installed using Composer or the Symfony binary:

composer require spiriitlabs/form-filter-bundle

Use it in two steps

create a form

<?php
namespace Project\Form\Filter;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Spiriit\Bundle\FormFilterBundle\Filter\Form\Type as Filters;

class RankFilterType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name', Filters\TextFilterType::class);
        $builder->add('rank', Filters\NumberFilterType::class);
    }
}

use it in your controller

class DefaultController extends AbstractController
{
    public function __invoke(
    Request $request, 
    FormFactoryInterface $formFactory,
    EntityManagerInterface $em,
    FilterBuilderUpdater $filterBuilderUpdater
    ): Response
    {
        $form = $formFactory->create(RankFilterType::class);

        $form->handleRequest($request);

        $filterBuilder = $em
            ->getRepository(MyEntity::class)
            ->createQueryBuilder('e');

        $filterBuilderUpdater->addFilterConditions($form, $filterBuilder);

        // now look at the DQL =)
        dump($filterBuilder->getDql());

        return $this->render('testFilter.html.twig', [
            'form' => $form,
        ]);
    }
}
