everyone. There is a similar question posted here, but the answer does not solve my error.

I'm trying to use Symfony 4.3 automatic validation on an entity, but it just doesn't work.

I've uncommented the two lines from validator.yaml and I have enabled validation: {enable_annotations: true} in framework.yaml config file, and it still does not work.

Even if I add or remove @Assert annotations from the entity, the validation always returns a zero-length array.

This is my entity class:

namespace App\Entity;

use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;

/**
 * Company
 *
 * @ORM\Table(name="company")
 * @ORM\Entity(repositoryClass="App\Repository\CompanyRepository")
 */

class Company
{
    /**
     * @var int
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var string
     *
     * @ORM\Column(name="type", type="string", length=255, nullable=false)
     * @Assert\NotNull
     */
    public $type;
}

As you can see, the type attribute cannot be null, but the validation is not working as expected. This is it:

$company = new Company();
$validator = Validation::createValidator();
$errors = $validator->validate($company);

At this point, $errors is just an empty array.

Is there any extra configuration needed? Does anybody have a theory?

I'm building a form which has an EntityType element, the problem I have is that I'm unable to have the placeholder translated.

Here is my code:

$builder
        ->add('Products', EntityType::class, [
            'mapped' => false,
            'expanded' => true,
            'multiple' => false,
            'required' => false,
            'class' => Product::class,
            'choices' => $options['step']->getProducts(),
            'placeholder' => 'form.mat.alreadyOwned',
            'label' => 'form.mat.alreadyOwned',
            'translation_domain' => 'messages'
        ])

When I use the form.mat.alreadyOwnedtranslation as the label it works fine, but I would like to use it in the placeholder instead. What am I missing?

Looking forward to any tips or tricks that you have to offer!

Is it possible to extract placeholders and titles translations from FormType class in Symfony4 using console command php bin/console translation:update --force uz ?

  {
      $builder
          ->add('title', null, [
              'attr' => ['placeholder' => 'job_title_placeholder'],
              'attr_translation_parameters' => [
                  'job_title_placeholder' => 'What needs to be done',
              ],
          ])
          ->add('description', TextareaType::class, [
              'attr' => ['placeholder' => 'job_description_placeholder'],
              'attr_translation_parameters' => [
                  'job_description_placeholder' => 'Describe project details',
              ],
          ])

After successful extracting keys 'job_title_placeholder' and 'description_title_placeholder' are not added to translation file

During email synchronization emails from mailbox doesn't convert in to case (or lead). How could I run this process?

I use oro crm 4 application, reconfigured mailbox according to documentation.
Email synchronization runs successfully by 'oro:cron:imap-sync' command. There are no errors or exceptions during executing, but also no new cases (or leads).

I tried to get this working:

$table = $this->createDataTable()
                ->add('firstname', TextColumn::class, ['label' => 'Vorname', 'orderable'=> true, 'field' => 'personalData.firstname'])
                ->add('lastname', TextColumn::class, ['label' => 'Nachname', 'orderable'=> true, 'field' => 'personalData.lastname'])
                ->add('email', TextColumn::class, ['label' => 'Nachname', 'orderable'=> true, 'field' => 'personalData.lastname'])
                ->add('phone', TextColumn::class, ['label' => 'Telefon', 'orderable'=> true, 'field' => 'personalData.phone'])
                ->add('mobilePhone', TextColumn::class, ['label' => 'Mobil', 'orderable'=> true, 'field' => 'personalData.mobilePhone'])
                ->add('gender', TextColumn::class, ['label' => 'Gender', 'orderable'=> true, 'field' => 'personalData.gender.abbreviation'])
                ->add('lastModified', DateTimeColumn::class, ['label' => 'letzte Änderung', 'orderable'=> true, 'format' => 'd.m.Y H:i:s'])
                ->add('dateCreated', DateTimeColumn::class, ['label' => 'Datum Erstellung', 'orderable'=> true, 'format' => 'd.m.Y H:i:s'])
                ->add('actions', TextColumn::class, ['label' => 'Aktionen', 'orderable'=> false, 'render' => function($value, $context) {
                        $user_id = $context->getId();
                        return sprintf('<button type="button" data-user-id="%s" class="btn btn-primary edit-user-btn"><i class="fas fa-pencil-alt fa-fw fa-fw"></i></button><button type="button" data-user-id="%s" class="btn btn-danger del-user-btn margin-left-10"><i class="fas fa-trash fa-fw fa-fw"></i></button>', $user_id, $user_id);
                    }])
                ->createAdapter(ORMAdapter::class, [
            'entity' => User::class,
        ]);

This results in the following error: Catchable Fatal Error: Object of class App\Entity\Gender could not be converted to string

So as workaround I could add the __toString method to the entity but unfortunately it does not solve the problem so that this column is also orderable.

Then I tried this approach:

$table = $this->createDataTable()
                ->add('firstname', TextColumn::class, ['label' => 'Vorname', 'orderable'=> true, 'field' => 'personalData.firstname'])
                ->add('lastname', TextColumn::class, ['label' => 'Nachname', 'orderable'=> true, 'field' => 'personalData.lastname'])
                ->add('email', TextColumn::class, ['label' => 'Nachname', 'orderable'=> true, 'field' => 'personalData.lastname'])
                ->add('phone', TextColumn::class, ['label' => 'Telefon', 'orderable'=> true, 'field' => 'personalData.phone'])
                ->add('mobilePhone', TextColumn::class, ['label' => 'Mobil', 'orderable'=> true, 'field' => 'personalData.mobilePhone'])
                ->add('gender', TextColumn::class, ['label' => 'Geschlecht', 'orderable'=> true, 'render' => function($value ,$context) {
                        $user_id = $context->getId();

                        $user = $this->getDoctrine()
                                ->getRepository(User::class)
                                ->findOneBy(['id' => $user_id]);

                        return $user->getPersonalData()->getGender()->getAbbreviation();
                    }])
                ->add('lastModified', DateTimeColumn::class, ['label' => 'letzte Änderung', 'orderable'=> true, 'format' => 'd.m.Y H:i:s'])
                ->add('dateCreated', DateTimeColumn::class, ['label' => 'Datum Erstellung', 'orderable'=> true, 'format' => 'd.m.Y H:i:s'])
                ->add('actions', TextColumn::class, ['label' => 'Aktionen', 'orderable'=> false, 'render' => function($value, $context) {
                        $user_id = $context->getId();
                        return sprintf('<button type="button" data-user-id="%s" class="btn btn-primary edit-user-btn"><i class="fas fa-pencil-alt fa-fw fa-fw"></i></button><button type="button" data-user-id="%s" class="btn btn-danger del-user-btn margin-left-10"><i class="fas fa-trash fa-fw fa-fw"></i></button>', $user_id, $user_id);
                    }])
                ->createAdapter(ORMAdapter::class, [
            'entity' => User::class,
        ]);

Now I can see the table loading but if I try to order the table I'm getting the following error message:

So I have an Entity "User" and this has a relation to the entity "personalData" - in addition "personalData" has a relation to "gender" --> I want to have the gender data displayed in the datatables and keep the order and search functionalities working

Is there any workaround or is this a bug?

I'm using Symfony 4 and want to create a composer package.

I want to put my Symfony project files on GitHub and create a composer package from the repository.

Does anyone have any advise on how to go about this.

I'm trying to implement a dynamic form with Symfony 4.3 based on the official documentation.

To simplicify, I have 3 entities: product, category and subcategory related to each other with OneToMany relationships as follows: a category can have multiple subcategories and a subcategory can have multiple products. By choosing a category (sport for example), I wanted to have the list of sport sub-categories displayed in the following field.

class ProductType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
        ->add('nom')
        ->add('categorie', EntityType::class, [
            'class'       => 'App\Entity\Categorie',
            //'placeholder' => '',
        ])
    ;



    $formModifier = function (FormInterface $form, Categorie $categorie = null) {
        $subcategories = null === $categorie ? [] : $categorie->getSubcategories();
        //var_dump($subcategories);
        $form->add('subcategorie', EntityType::class, [
            'class' => 'App\Entity\Subcategorie',
            //'placeholder' => '',
            'choices' => $subcategories,
        ]);
    };

    $builder->addEventListener(
        FormEvents::PRE_SET_DATA,
        function (FormEvent $event) use ($formModifier) {
            // this would be your entity
            $data = $event->getData();
            //var_dump($data);
            //die;
            $formModifier($event->getForm(), $data->getCategorie());
        }
    );

    $builder->get('categorie')->addEventListener(
        FormEvents::POST_SUBMIT,
        function (FormEvent $event) use ($formModifier) {
            $categorie = $event->getForm()->getData();

            $formModifier($event->getForm()->getParent(), $categorie);
        }
    );
//...
}

My concern is that I can not getthe value of my dumps ($data and $subcategories): they are always on NULL. So, I can not find my subcategories in the form.

I'm asking because I'm really blocked for a while and I can not find the bug in this code based on the Symfony documentation.

and sorry for my English, I'm French so I use a translator. Here is a part of my model to illustrate my words:

So that's the trouble. I am in my Admin Settings page. On this page I will be able to add / delete holiday types. But when I delete types of holidays, it would have to delete things cascading in the database.

In fact the principle of the site is the following:

Users ask for their holidays. For that they give the type of leave for which they will be absent. And for each type of holiday, users have a balance.

So I have this:

ParametresAdmin.php:

/**
     * @ORM\OneToMany(targetEntity="App\Entity\TypeConge", mappedBy="parametresAdmin", orphanRemoval=true, cascade={"persist", "remove"})
     */
    private $typesConges;

TypeConge.php:

/**
     * @ORM\Column(type="string", length=255, unique=true)
     */
    private $nom;
/**
     * @ORM\OneToMany(targetEntity="App\Entity\Absence", mappedBy="typeConge", cascade={"persist", "remove"})
     */
    private $absences;

SoldeConges.php:

/**
 * @ORM\ManyToOne(targetEntity="App\Entity\TypeConge", cascade={"persist", "remove"})
 * @ORM\JoinColumn(nullable=false)
 */
private $typeConge;

/**
 * @ORM\ManyToOne(targetEntity="App\Entity\User", inversedBy="soldeConges")
 * @ORM\JoinColumn(nullable=false)
 */
private $user;

/**
 * @ORM\Column(type="float", nullable=true)
 */
private $solde;

Absence.php:

/**
     * @ORM\ManyToOne(targetEntity="App\Entity\User", inversedBy="absences")
     * @ORM\JoinColumn(nullable=false)
     */
    private $user;
/**
     * @ORM\ManyToOne(targetEntity="App\Entity\TypeConge", inversedBy="absences")
     * @ORM\JoinColumn(nullable=false)
     */
    private $typeConge;

User.php:

/**
     * @ORM\OneToMany(targetEntity="App\Entity\SoldeConges", mappedBy="user", orphanRemoval=true, fetch="EAGER", cascade={"remove"})
     */
    private $soldeConges;
/**
     * @ORM\OneToMany(targetEntity="App\Entity\Absence", mappedBy="user", orphanRemoval=true)
     */
    private $absences;

So, in my admin settings, if I delete a type of leave, it must follow this pattern:

• Suppression of absences related to the type of leave.
• Removal of the 'soldeUser' from User, for balances that are related to the type of leave.
• Suppression of the 'typeConge' (type of holiday)

But whith my code, I've this error when I try to delete a type of holiday :

An exception occurred while executing 'DELETE FROM type_conge WHERE id = ?' with params [9]:

SQLSTATE[23000]: Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails (congestest2.solde_conges, CONSTRAINT FK_BE0A8BDB753BDA5 FOREIGN KEY (type_conge_id) REFERENCES type_conge (id))

I'am using symfony 4

I have a custom Symfony 4 deserializer

class CardImageDecoder implements EncoderInterface, DecoderInterface
{
    public function encode($data, $format, array $context = [])
    {
        if($format !== 'json') {
            throw new EncodingFormatNotSupportedException(sprintf('Format %s is not supported by encoder %s', $format, __CLASS__));
        }

        $result = json_encode($data);

        if(json_last_error() !== JSON_ERROR_NONE) {
            // don't bother with a custom error message
            throw new \Exception(sprintf('Unable to encode data, got error message: %s', json_last_error_msg()));
        }

        return $result;
    }

    public function supportsEncoding($format)
    {
        return 'json' === $format;
    }

    public function decode($data, $format, array $context = [])
    {
        if($format !== 'array') {
            throw new DecodingFormatNotSupportedException(sprintf('Format %s is not supported by encoder %s', $format, __CLASS__));
        }

        if(!is_array($data)) {
            throw new \UnexpectedValueException(sprintf('Expected array got %s', gettype($data)));
        }

        $cardInstance = new CardImages();
        $cardInstance->setHeight($data['h'] ?? 0);
        $cardInstance->setPath($data['url'] ?? '');
        $cardInstance->setWidth($data['w'] ?? 0);

        return $cardInstance;
    }

    public function supportsDecoding($format)
    {
        return 'array' === $format;
    }
}

The way I'm deserializing is pretty straight forward:

$json = '
{
"url": "some url",
"h": 1004,
"w": 768
}';

$encoders = [new CardImageDecoder()];
$normalizers = [new ObjectNormalizer()];
$serializer = new Serializer($normalizers, $encoders);

$cardImage = $serializer->deserialize(json_decode($json, true), CardImages::class, 'array');

/** @var $cardImage CardImages */
var_dump($cardImage);

However, I get this result returned:

object(App\Entity\CardImages)#158 (5) {
  ["id":"App\Entity\CardImages":private]=>
  NULL
  ["path":"App\Entity\CardImages":private]=>
  NULL
  ["height":"App\Entity\CardImages":private]=>
  NULL
  ["width":"App\Entity\CardImages":private]=>
  NULL
  ["movie":"App\Entity\CardImages":private]=>
  NULL
}

Now, if I were to do a dump, just before the return in the decode part of the decoder, I'd get this:

...
$cardInstance->setWidth($data['w'] ?? 0);

var_dump($cardInstance);

object(App\Entity\CardImages)#153 (5) {
  ["id":"App\Entity\CardImages":private]=>
  NULL
  ["path":"App\Entity\CardImages":private]=>
  string(8) "some url"
  ["height":"App\Entity\CardImages":private]=>
  int(1004)
  ["width":"App\Entity\CardImages":private]=>
  int(768)
  ["movie":"App\Entity\CardImages":private]=>
  NULL
}

Ignoring the not set properties(which I'm fine with), it should work quite nicely, but it doesn't.

For the life of me I can't figure out what's wrong.

Any help is appreciated.

I have a project which is using symfony 1.x with PHP 5.3. I want to upgrade it to the latest version of symfony which is 4.x.

My first question is, is it possible ?

If it is how to do that ?

else do I have to code it from the scratch using the symfony 4 ?

i have a project developed with symfony 4.3, i try to add the guard authentication service using make:auth command.

i have this line error :

The service "security.authentication.provider.guard.main" has a dependency on a non-existent service "App\Security\LoginFormAuthenticator"

User Deprecated: Auto-injection of the container for "App\Controller\SecurityController" is deprecated since Symfony 4.2. Configure it as a service instead.

in the services.yaml, i put these lines:

I have a form in Symfony 4 where I implement the DateType as a text field

->add('DateOfBirth', DateType::class, array(
    'required' => false,
    'widget' => 'single_text',
    'empty_data' =
))

however the field is optional to fill in for the form. When I submit the form with an empty value for that field I receive the error:

Expected argument of type "DateTimeInterface", "NULL" given.

erroring on the line

$form->handleRequest($request);

It seems I need to pass in a default value (i.e. - 1/1/1990) as null is not a valid DateTime value? What is the correct way to handle this? I looked on this page and tried various things (i.e. - changing input type) but nothing seems to fix this.

Thanks in advance!

I'm using Swiftmail to send emails with gmail.I have configured the MAILER_URL in my .env. But my password has got a special character in it. I've read that you must encode your password when there is a special character but I don't know how.

# For Gmail as a transport, use: "gmail://username:password@localhost"
# For a generic SMTP server, use: "smtp://localhost:25?encryption=&auth_mode="
# Delivery is disabled by default via "null://localhost"

I am trying to get default radio checked with symfony or twig but i am not able to do

for example i have a gender form field that contains male and female and i want to have one of them to be checked by default

i looked in symfony documentation but i din't find any solution

This is the formfield that i want to set a default

->add('gender', ChoiceType::class, [
      'choices' => [
           'Male' => 'male',
           'Female' => 'female',
       ],
       'expanded' => true
])

This is twig code

{% for gender in form.member.gender %}
  {{
       form_row(gender, {label_attr: {'class': 'radio-custom'}})
  }}
{% endfor %}

Can you help me to solve this problem?

I would like to show error messages in the top of my registration form. I created my registration form:

<div class="example-wrapper">
<h1>Register</h1>
{{ form_start(form) }}
    {{ form_row(form.email) }}
    {{ form_row(form.plainPassword.first) }}
    {{ form_row(form.plainPassword.second) }}
    {{ form_row(form.firstname) }}
    {{ form_row(form.lastname) }}
    {{ form_row(form.termsAccepted) }}
    <button type="submit">Register!</button>
{{ form_end(form) }}
</div>

And on my UserType class, I added all necessaries input:

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
       ->add('email', EmailType::class)
       ->add('plainPassword', RepeatedType::class, array(
            'type' => PasswordType::class,
            'first_options' => array('label' => 'Password'),
            'second_options' => array('label' => 'Repeat Password'),
            'constraints' => [
                new NotBlank([
                    'message' => 'Enter a valid password.'
                ]),
                new Length([
                    'min' => 8,
                    'minMessage' => 'Password must be at least 8 characters.'
                ])
            ]
         ))
         ->add('firstname', TextType::class)
         ->add('lastname', TextType::class)
         ->add('termsAccepted', CheckboxType::class, array(
              'mapped' => false,
              'constraints' => new IsTrue(),
         ))
        ;
    }}

Every time I get an error message, correctly displayed, I found it under the concerned input and not in the top of my registration form. I added this on my form but don't help:

{{ form_errors(form) }}

Any suggestion?

I have annotation (working)

@IsGranted("editBlog", subject="company")

but I want something like this (not working):

@IsGranted("edit", subject="company.blog")

"Company" and "Blog" are Doctrine Entities with OneToOne relation. But my action have only "company" parameter.

    /**
     * @IsGranted("editBlog", subject="company")
     * @param CompanyEntity $company
       ...
     * @return Response
     */
    final public function defaultAction(
        CompanyEntity $company,
        ...
    )
    {
     ...
    }

How to access a variable in a subject?

Thanks!
