Symfony validator extension for RollerworksSearch

v2.0.0-ALPHA21 2019-07-15 14:06 UTC


Build Status

The RollerworksSearch Symfony Validator facilitates the validating of input values using the Symfony Validator component.


This validation is meant to be used for business rules like a minimum/maximum value range or disallowing specific patterns. The data transformers already ensure the value is properly transformed.


To install this extension, add the rollerworks/search-symfony-validator package in your composer.json and update your dependencies.

$ composer require rollerworks/search-symfony-validator

Next you need to enable the Rollerworks\Component\Search\Extension\Symfony\Validator\ValidatorExtension in the SearchFactoryBuilder and pass the Input Validator to your Input Processor.

use Rollerworks\Component\Search\Searches;
use Rollerworks\Component\Search\Extension\Validator\ValidatorExtension;
use Rollerworks\Component\Search\Extension\Validator\InputValidator;
use Rollerworks\Component\Search\Input\StringQueryInput;
use Symfony\Component\Validator\Validation;

$searchFactory = Searches::createSearchFactoryBuilder();
    ->addExtension(new ValidatorExtension())
    // ...


$validatorBuilder = Validation::createValidatorBuilder();
$validator = $validatorBuilder->getValidator();

$inputProcessor = new StringQueryInput(new InputValidator($validator));

That's it, you can now use the Validator. But note only search fields with constraints set will be actually validated by the validator.

Setting validation constraints

Before you continue make sure you have a good understanding of what Constraints are and how they are to be used. See Symfony Validator component for more information.

You can configure the constraint on a per-field basis when building your FieldSet:

use Symfony\Component\Validator\Constraints as Assert;
use Rollerworks\Component\Search\Extension\Core\Type\IntegerType;

// ..

$fieldSetBuilder = $searchFactory->createFieldSetBuilder()
$fieldSetBuilder->add('id', IntegerType::class, ['constraints' => new Assert\Range(['min' => 5])]);

Or when your (custom) type always needs these specific constraints make the constraints part of the field type using the configureOptions method of the field type. Using:

public function configureOptions(OptionsResolver $resolver)
            'constraints' => new Assert\Length(array('min' => 101)),

Symfony framework integration

Note: The Symfony integration bundle for RollerworksSearch already enables the Symfony validator service. You don't need to do anything but configure your field's constraints.
