Validators

ITIN validator

ITIN - Individual Taxpayer Identification Number

<?php

require_once './vendor/autoload.php';

use mmo\sf\Validator\Constraints\Itin;
use Symfony\Component\Validator\Validation;

$validator = Validation::createValidatorBuilder()->getValidator();
$validator->validate('foo', new Itin()); // NOT VALID
$validator->validate('918-97-5273', new Itin()); // VALID

Birthday

require_once './vendor/autoload.php';

use mmo\sf\Validator\Constraints\Birthday;
use Symfony\Component\Validator\Validation;

$validator = Validation::createValidatorBuilder()->getValidator();
$validator->validate((new DateTimeImmutable('now'))->modify('-5 years'), new Birthday(['minAge' => 18])); // NOT VALID
$validator->validate((new DateTimeImmutable('now'))->modify('-120 years'), new Birthday()); // NOT VALID
$validator->validate((new DateTimeImmutable('now'))->modify('-5 years'), new Birthday()); // VALID

BankRoutingNumber

require_once './vendor/autoload.php';

use mmo\sf\Validator\Constraints\BankRoutingNumber;
use Symfony\Component\Validator\Validation;

$validator = Validation::createValidatorBuilder()->getValidator();
$validator->validate('1234567890', new BankRoutingNumber()); // NOT VALID
$validator->validate('275332587', new BankRoutingNumber()); // VALID

Utf8Letters

Only UTF-8 letters and dashes.

require_once './vendor/autoload.php';

use mmo\sf\Validator\Constraints\Utf8Letters;
use Symfony\Component\Validator\Validation;

$validator = Validation::createValidatorBuilder()->getValidator();
$validator->validate('foo.bar', new Utf8Letters()); // NOT VALID
$validator->validate('Zażółć', new Utf8Letters()); // VALID

Utf8Words

Only UTF-8 letters, dashes, and spaces are allowed. Useful to validate the full name of a person.

require_once './vendor/autoload.php';

use mmo\sf\Validator\Constraints\Utf8Words;
use Symfony\Component\Validator\Validation;

$validator = Validation::createValidatorBuilder()->getValidator();
$validator->validate('foo.bar', new Utf8Words()); // NOT VALID
$validator->validate('Zażółć gęślą', new Utf8Words()); // VALID

OnlyDigits

Only digits are allowed.

<?php

use mmo\sf\Validator\Constraints\OnlyDigits;
use Symfony\Component\Validator\Validation;

require_once './vendor/autoload.php';

$validator = Validation::createValidatorBuilder()->getValidator();
$violations = $validator->validate('f1234', new OnlyDigits()); // NOT VALID
$violations = $validator->validate('1234567', new OnlyDigits()); // VALID

ArrayConstraintValidatorFactory

Validators which don't follow a convention of naming a Constraint and ConstraintValidator, will not be found by the default implementation of ConstraintValidatorFactory.

The class ArrayConstraintValidatorFactory resolve this problem, you can map ConstraintValidator to object.

use Symfony\Component\Validator\Validation;
use mmo\sf\Validator\ArrayConstraintValidatorFactory;
use Kiczort\PolishValidatorBundle\Validator\Constraints\NipValidator;

// ....
$validatorFactory = new ArrayConstraintValidatorFactory(['kiczort.validator.nip' => new NipValidator()]);
$validator = Validation::createValidatorBuilder()
            ->setConstraintValidatorFactory($validatorFactory)
            ->getValidator();
// ...

Translator

FakeTranslator

The FakeTranslator class can be used in a unit tests instead of using a stub. At the moment only id and locale arguments are supported.

<?php

require_once './vendor/autoload.php';

use mmo\sf\Translation\FakeTranslator;

$translator = new FakeTranslator('en');
$translator->trans('foo'); // en-foo
$translator->trans('foo', [], null, 'us'); // us-foo

Security

Encrypter

Encrypter is used to encrypt string value. All encrypted values are encrypted using OpenSSL and the AES-256-CBC cipher (as default).

<?php

use mmo\sf\Util\Encrypter;

require_once './vendor/autoload.php';

$encrypter = new Encrypter('my-secret-key');
$secret = $encrypter->encryptString('secret message');
$plaintext = $encrypter->decryptString($secret); 

AlwaysTheSameEncoderFactory (Symofny 4.4 and 5.4)

AlwaysTheSameEncoderFactory is useful in integration tests with combination of UserPasswordEncoder. No matter which implementation of UserInterface you pass, will always be used the same password encoder injected via constructor.

<?php

require_once './vendor/autoload.php';

use mmo\sf\Security\Test\AlwaysTheSameEncoderFactory;
use Symfony\Component\Security\Core\Encoder\PlaintextPasswordEncoder;
use Symfony\Component\Security\Core\Encoder\UserPasswordEncoder;

$factory = new AlwaysTheSameEncoderFactory(new PlaintextPasswordEncoder());
$encoder = new UserPasswordEncoder($factory);
// now you can pass $encoder to your service, which expect `UserPasswordEncoderInterface`

MemoryUserProvider (only Symfony 4.4 nad 5.4)

For Symfony 6.4+ use build-in provider \Symfony\Component\Security\Core\User\InMemoryUserProvider.

MemoryUserProvider is a simple non persistent user provider for tests.

This provider compares to InMemoryUserProvider allows for store any user objects, which implement the UserInterface interface instead of only the internal Symfony User class.

<?php

require_once './vendor/autoload.php';

use mmo\sf\Security\Test\MemoryUserProvider;
use Symfony\Component\Security\Core\User\User;

$provider = new MemoryUserProvider(User::class, []);
$provider->createUser(new User('test', 'foo'));
$provider->loadUserByUsername('test');

Form

RamseyUuidToStringTransformer

Transforms between a UUID string, and a UUID object. Symfony 5.3 include an own UuidToStringTransformer transformer, but you need also use a symfony/uuid component. This transformer works with a ramsey/uuid library.

PrimaryKeyToEntityTransformer

Transforms between a primary key(composite primary key is not supported), and an entity.

StringInsteadNullTransformer

The goal of this transformer is to fix an error when you have a form with ChoiceType and pass an empty value for this field and your entity/DTO expect only string value you get error "Expected argument of type "string", "NULL" given at property path ...".

The Symfony changes this empty string to null value (due to ChoiceToValueTransformer). You can add StringInsteadNullTransformer as a model transformer, so null values will be transformed to an empty string.

//...

use mmo\sf\Form\DataTransformer\StringInsteadNullTransformer;

class StateType extends AbstractType
{
    private StatesProviderInterface $statesProvider;

    public function __construct(StatesProviderInterface $statesProvider)
    {
        $this->statesProvider = $statesProvider;
    }

    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder->addModelTransformer(new StringInsteadNullTransformer());
    }

    public function configureOptions(OptionsResolver $resolver): void
    {
        $resolver->setDefaults(['choices' => $this->statesProvider->getStates()]);
    }

    public function getParent(): string
    {
        return ChoiceType::class;
    }
}

ReplaceIfNotSubmittedListener

The goal of this EventSubscriber is to overwrite data of model, when no data has been sent. Imagine scenario, that you have entities:

class FormDto
{
    /**
     * @var string|null 
    */
    public $text;
    
    /**
     * @var PersonDto|null
     */
    public $person;
}

class PersonDto
{
    /**
     * @var string|null
     */
    public $firstName;

    /**
     * @var string|null
     */
    public $lastName;
}

Property $person is not null. You want to set this value to null, because PersonDto cannot be in "split state". Both properties of PersonDto has to be set (cannot be empty). When the form is submitted, and Symfony parameter $clearMissing of method submit is set to false, then due to this EventSubscriber the property person of FormDto will be set to null value. Without this EventSubscriber, an empty PersonDto object will be created which will be passed to FormDto.

See also test \mmo\sf\tests\Form\ReplaceIfNotSubmittedFormTest.

use mmo\sf\Form\ReplaceIfNotSubmittedListener;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\FormBuilderInterface;

class FormToTestReplaceValueType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder->add('text', TextType::class);
        $builder->add('person', PersonType::class, [
            'required' => false,
        ]);
        $builder->get('person')->addEventSubscriber(new ReplaceIfNotSubmittedListener(null));
    }
}

lexik/jwt-authentication-bundle

Revoke JWT token

The JWT is stateful token. We don't need to store them. This property create problem, when we need to revoke (invalidate) a token. Some resources: How to change a token to be invalid status? or Invalidating JSON Web Tokens

In a file config/packages/cache.yaml we register a new pool cache.jwt. In this example as adapter we use Redis.

cache.jwt:
    adapter: cache.adapter.redis

In a file config/routes.yaml we add a router:

api_logout:
    path: /api/sessions
    controller: 'mmo\sf\JWTAuthenticationBundle\Controller\LogoutAction'
    methods: DELETE

Finally, we need to register services in config/services.yaml file. We create alias for interface JitGeneratorInterface to RamseyUuid4JitGenerator and configure listeners. For CheckRevokeListener we need pass correct arguments for cache pool (we create custom pool - cache.jwt in config/packages/cache.yaml) and router name api_logout, which we add in a file config/routes.yaml

mmo\sf\JWTAuthenticationBundle\Controller\LogoutAction:
  tags: ['controller.service_arguments']
  mmo\sf\JWTAuthenticationBundle\JitGenerator\RamseyUuid4JitGenerator: ~
  mmo\sf\JWTAuthenticationBundle\JitGenerator\JitGeneratorInterface:
    alias: mmo\sf\JWTAuthenticationBundle\JitGenerator\RamseyUuid4JitGenerator

  mmo\sf\JWTAuthenticationBundle\Listener\CheckRevokeListener:
    arguments:
      - '@request_stack'
      - '@cache.jwt'
      - 'api_logout'
      - 'key_prefix_in_cache.'
    tags:
      - { name: kernel.event_listener, event: lexik_jwt_authentication.on_jwt_decoded, method: onJWTDecoded }
  mmo\sf\JWTAuthenticationBundle\Listener\AddJitClaimListener:
    tags:
      - { name: kernel.event_listener, event: lexik_jwt_authentication.on_jwt_created, method: onJWTCreated }

Util

Transliterator

Class Transliterator contains one static method transliterate to returns transliterated version of a string. Based on yii2 Inflector

<?php

require_once './vendor/autoload.php';

use mmo\sf\Util\Transliterator;

Transliterator::transliterate('¿Español?'); // Espanol?
Transliterator::transliterate('Українська: ґанок, європа', Transliterator::TRANSLITERATE_STRICT); // Ukraí̈nsʹka: g̀anok, êvropa

EntityTestHelper

The class EntityTestHelper helps set a value for a private field e.g. id.

<?php

require_once './vendor/autoload.php';

use mmo\sf\Util\EntityTestHelper;

EntityTestHelper::setPrivateProperty($entity, 12);
EntityTestHelper::setPrivateProperty($entity, 12, 'fieldName');

ObjectHelper

arrayToObject

This static method recursive converts an array to stdClass.

<?php

require_once './vendor/autoload.php';

use mmo\sf\Util\ObjectHelper;

$object = ObjectHelper::arrayToObject(['foo' => 'bar', 'baz' => ['foo' => 'bar']]);

// class stdClass#3 (2) {
//   public $foo =>
//   string(3) "bar"
//   public $baz =>
//   class stdClass#2 (1) {
//     public $foo =>
//     string(3) "bar"
//   }
// }

Commands

S3CreateBucketCommand

Command mmo:s3:create-bucket creates a S3 bucket. When the option skip-if-exists is enabled, and the bucket exists the process will finish successful. You can use the option --public so everyone can get objects from a bucket.

To use this command you must register two services. In config/services.yaml register a service s3client and mmo\sf\Command\S3CreateBucketCommand.

services:
  # ...
  s3client:
    class: Aws\S3\S3Client
    arguments:
      - version: '2006-03-01' # or 'latest'
        endpoint: '%env(AWS_S3_ENDPOINT)%'
        use_path_style_endpoint: true
        region: "us-east-1" # 'eu-central-1' for example
        credentials:
          key: '%env(AWS_S3_KEY)%'
          secret: '%env(AWS_S3_SECRET)%'
  mmo\sf\Command\S3CreateBucketCommand:
    arguments:
      $s3Client: '@s3client'

LiipImagineBundle

ResolverAlwaysStoredDecorator

This resolver always returns true whether image already exists or not.

liip_imagine:
  # ...
  resolvers:
    offers:
      flysystem:
        filesystem_service: oneup_flysystem.images_filesystem
        root_url:           "%env(AWS_S3_URL)%"
        cache_prefix:       miniatures
        visibility:         public
  cache: always_stored_resolver
services:
  # ...
  mmo\sf\ImagineBundle\ResolverAlwaysStoredDecorator:
    arguments:
      $resolver: '@liip_imagine.cache.resolver.offers'
    tags:
      - { name: "liip_imagine.cache.resolver", resolver: always_stored_resolver }

cyve/json-schema-form-bundle

CyveJsonSchemaMapper

The default implementation of data mapper (PropertyPathMapperTest) also set array key when the value is null This is a problem when fields in JsonSchema are not required. Schema validator doesn't check whether the field value is set. This is something different from the Symfony Validator component. In Symfony if the field value is the null or empty string, the validation is skipped. In JsonSchemaValidator event optional field with value null must match validation rules. Also cyve/json-schema-form-bundle not supported multiple types of field.

Doctrine

IgnoreSchemaTablesListener

This listener expects table names, which will be ignored during comparing database schema with entities. It is useful when you manually manage the table's schema for some of your entities. This is a similar solution to Manual tables from DoctrineMigrationsBundle

mmo\sf\Doctrine\IgnoreSchemaTablesListener:
  arguments:
    $ignoredTables: 
      - schema._table1_
      - schema.table2
  tags:
    - {name: doctrine.event_listener, event: postGenerateSchema }

Serializer

MyCLabsEnumNormalizer

Normalizer and denormalizer for Enum class from package myclabs/php-enum.

<?php

require_once './vendor/autoload.php';

use mmo\sf\Serializer\Normalizer\MyCLabsEnumNormalizer;
use MyCLabs\Enum\Enum;
use Symfony\Component\Serializer\Serializer;

/**
 * @method static static DRAFT()
 * @method static static PUBLISHED()
 */
class MyEnum extends Enum
{
    private const DRAFT = 'draft';
    private const PUBLISHED = 'published';
}

$serializer = new Serializer([new MyCLabsEnumNormalizer()]);
$serializer->denormalize('draft', MyEnum::class); // return instance of MyEnum

MoneyNormalizer

Normalizer and denormalizer for Money class from package moneyphp/money.

<?php

require_once './vendor/autoload.php';

use Money\Money;
use mmo\sf\Serializer\Normalizer\MoneyNormalizer;
use Symfony\Component\Serializer\Serializer;

$serializer = new Serializer([new MoneyNormalizer()]);
$money = $serializer->denormalize($serializer->normalize(Money::EUR(100)), Money::class);

EventSubscriber

PerformanceSubscriber

This listener connects to HttpKernel events (RequestEvent and TerminateEvent) to log the performance of an endpoint via LoggerInterface. The entry in the log includes duration, HTTP method, URL, and PID. Analysis of those data allows us to find the most time-consuming endpoints. We can have some suspects and start a deeper analysis of the performance of those endpoints via Xdebug or Blackfire.

Create a new channel and handler for monolog in config/packages/monolog.yaml.

# config/packages/monolog.yaml

monolog:
  channels: ['performance']
  handlers:
    performancelog:
      type: stream
      path: php://stderr
      level: debug
      channels: [performance]

Next register listener in config/services.yaml.

# config/services.yaml
services:
  mmo\sf\EventSubscriber\PerformanceSubscriber:
    arguments:
      $logger: '@monolog.logger.performance'

When we refresh page in log (in this configuration logs are sent to stderr) we should see something like this: [2021-08-30 15:15:19] performance.INFO: The request "GET /admin/login" took "1.041289" second. {"url":"/admin/login","method":"GET","pid":7,"status_code":200}
