So this is going to sound a bit complicated since I'm a total noob to JSON but bear with me guys, I really need this.let me start by showing my entity
<?phpnamespace App\Entity;use Doctrine\ORM\Mapping as ORM;/** * @ORM\Entity(repositoryClass="App\Repository\TypeParkingRepository") */class TypeParking{ /** * @ORM\Id() * @ORM\GeneratedValue() * @ORM\Column(type="integer") */ private $id; /** * @ORM\Column(type="string", length=55) */ private $libelle; /** * @ORM\Column(type="date", nullable=true) */ private $jourdebut; /** * @ORM\Column(type="date", nullable=true) */ private $jourfin; /** * @ORM\Column(type="json_array", nullable=true) */ private $exception; public function getId(): ?int { return $this->id; } public function getJourdebut(): ?\DateTimeInterface { return $this->jourdebut; } public function setJourdebut(\DateTimeInterface $jourdebut): self { $this->jourdebut = $jourdebut; return $this; } public function getJourfin(): ?\DateTimeInterface { return $this->jourfin; } public function setJourfin(\DateTimeInterface $jourfin): self { $this->jourfin = $jourfin; return $this; } public function getException() { return array_merge(['name' => null,'datedebut' => null, 'datefin' => null, 'heuredebut' => null, 'heurefin' => null, // other sub-fields "empty" values ], $this->exception ?? [] // prevent array_merge from failing if exception is empty ); } public function setException($exception): self { $this->exception = $exception; return $this; } public function getLibelle(): ?string { return $this->libelle; } public function setLibelle(string $libelle): self { $this->libelle = $libelle; return $this; }}As you can see I have this property called exception, now this property has many sub properties such as name, datedebut,datefin...So I had to use JSON format for it.so I created this formtype called TypeParkingType.php
<?phpnamespace App\Form;use Symfony\Component\Form\Extension\Core\Type\TextType;use Symfony\Component\Form\Extension\Core\Type\DateTimeType;use Symfony\Component\Form\Extension\Core\Type\TimeType;use Symfony\Component\Form\Extension\Core\Type\DateType;use App\Entity\TypeParking;use Symfony\Component\Form\AbstractType;use Symfony\Component\Form\FormBuilderInterface;use Symfony\Component\OptionsResolver\OptionsResolver;class TypeParkingType extends AbstractType{ public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('libelle') ->add('tempsmax') ->add('jourdebut') ->add('jourfin') ->add('jourstravail_jour', TextType::class, ['property_path' => 'jourstravail[jour]']) ->add('jourstravail_debut', TextType::class, ['property_path' => 'jourstravail[debut]']) ->add('jourstravail_fin', TextType::class, ['property_path' => 'jourstravail[fin]']) ->add('Exception_Name', TextType::class, ['property_path' => 'exception[name]']) ->add('Starting_date', DateTimeType::class, ['property_path' => 'exception[datedebut]', ]) ->add('Ending_date', DateTimeType::class, ['property_path' => 'exception[datefin]', ]) ->add('Starting_time', TextType::class, ['property_path' => 'exception[heuredebut]']) ->add('Ending_time', TextType::class, ['property_path' => 'exception[heurefin]']) ; } public function configureOptions(OptionsResolver $resolver) { $resolver->setDefaults(['data_class' => TypeParking::class, ]); }}Sadly this doesn't work because even after inserting the data into the database it does so in a impractical way that's impossible to read.To make it more complicated, each form can have more than one exception meaning that I have to parse the data in a way like: Ex: {exceptionName(datedebut:...,datefin...,time:...),exceptionname2....}
what I mean by impossible is that it gives me a string like this one https://i.sstatic.net/emsYY.jpg which:
gives me this error when I go to the edit page for the chosen type:
Unable to transform value for property path "exception[datedebut]": Expected a \DateTimeInterface.I can't extract the data one by one from it
TL;DR: how can I insert the values related to exception into a single JSON string in the database.
