About

This project is a Symfony bridge for small/forms.

small/forms- bundle is a library to validate, normalize and denormalize api data.

This package bypass symfony normalizer.

Install

composer require small/forms-bundle

Inline forms

You can easily create a form inside your controller action.

For example, we want to check that this entry data match our controller action :

\Small\Forms\Form\FormBuilder::createInlineForm()
    ->addField(
        'name', 
        new \Small\Forms\Form\Field\Type\StringType(),
        [new \Small\Forms\ValidationRule\ValidateNumberCharsLessThan(256)]
    )->addField('age', new \Small\Forms\Form\Field\Type\IntType())
;

try {
    $form->fillFromSymfonyRequest($request)
        ->validate($messages = new \Small\Collection\Collection\StringCollection())
    ;
} catch (\Small\Forms\ValidationRule\Exception\ValidationFailException) {
    return new \Symfony\Component\HttpFoundation\JsonResponse($messages, \Symfony\Component\HttpFoundation\Response::HTTP_BAD_REQUEST);
}

$arrayData = $form->toArray();

Class forms

If you want to reuse your form, you can declare it as a class :

namespace App\Form;

class PersonForm extends \Small\Forms\Form\AbstractForm
{

    public function build(): self {
        
        $this->addField(
            'name', 
            new \Small\Forms\Form\Field\Type\StringType(),
            [new \Small\Forms\ValidationRule\ValidateNumberCharsLessThan(256)]
        );
        
        $this->addField('age', new \Small\Forms\Form\Field\Type\IntType());
        
    }
    
}

And simply use it in your controllers :

try {
    $form = \Small\Forms\Form\FormBuilder::createFromFormClass(App\Form\PersonForm::class)
        ->fillFromSymfonyRequest($request)
        ->validate($messages = new \Small\Collection\Collection\StringCollection())
    ;
} catch (\Small\Forms\ValidationRule\Exception\ValidationFailException) {
    return new \Symfony\Component\HttpFoundation\JsonResponse($messages, \Symfony\Component\HttpFoundation\Response::HTTP_BAD_REQUEST);
}

$arrayData = $form->toArray();

Standard objects with attributes

You can also create a form directly from object

namespace App\DTO;

use Small\Forms\Modifier\NullIfEmptyModifier;use Small\Forms\ValidationRule\ValidateNotEmpty;
use Small\Forms\ValidationRule\ValidateGreaterOrEqual;

class Person
{

    #[ValidateNotEmpty]
    private string $name;
    #[ValidateGreaterThanOrEqual(18)]
    #[NullIfEmptyModifier]
    private int $age;

}

namespace App\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class Employe
{
    
    #[ORM\Id]
    #[ORM\GeneratedValue]
    #[ORM\Column]
    private ?int $id = null;

    #[ORM\Column]
    #[Assert\NotBlank]
    private string $name;
    #[ORM\Column]
    private int $age;
    #[ORM\Column]
    private int $idService;
    
    #[ORM\ManyToOne(inversedBy: 'Service')]
    #[ORM\JoinColumn(name: "idService", referencedColumnName: "id", nullable: true)]
    private Service|null $service = null;

}

try {

    $form = \Small\Forms\Form\FormBuilder::createFromAdapter(
        new \Small\Forms\Adapter\AnnotationAdapter($person)
    )->validate($messages = new \Small\Collection\Collection\StringCollection())
    ->hydrate($employe = new App\Entity\Employe());

} catch (\Small\Forms\ValidationRule\Exception\ValidationFailException) {
    return new \Symfony\Component\HttpFoundation\JsonResponse($messages, \Symfony\Component\HttpFoundation\Response::HTTP_BAD_REQUEST);
}

$useCase->joinCompanyUseCase($employe);

$form->fillFromObject($employe)
    ->hydrate($person)
;

return new \Symfony\Component\HttpFoundation\JsonResponse($person);

The validation rules will be parsed from your entity class php attributes.

Symfony DTO or entities

You can also create a form from DTO object

namespace App\DTO;

use Symfony\Component\Validator\Constraints as Assert;

class Person
{

    #[Assert\NotBlank]
    private string $name;
    #[Assert\GreaterThanOrEqual(18)]
    private int $age;

}

namespace App\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class Employe
{
    
    #[ORM\Id]
    #[ORM\GeneratedValue]
    #[ORM\Column]
    private ?int $id = null;

    #[ORM\Column]
    #[Assert\NotBlank]
    private string $name;
    #[ORM\Column]
    private int $age;
    #[ORM\Column]
    private int $idService;
    
    #[ORM\ManyToOne(inversedBy: 'Service')]
    #[ORM\JoinColumn(name: "idService", referencedColumnName: "id", nullable: true)]
    private Service|null $service = null;

}

try {

    $form = \Small\Forms\Form\FormBuilder::createFromAdapter(
        new \Small\Forms\Adapter\SymfonyAnnotationAdapter($person)
    )->validate($messages = new \Small\Collection\Collection\StringCollection())
    ->hydrate($employe = new App\Entity\Employe());

} catch (\Small\Forms\ValidationRule\Exception\ValidationFailException) {
    return new \Symfony\Component\HttpFoundation\JsonResponse($messages, \Symfony\Component\HttpFoundation\Response::HTTP_BAD_REQUEST);
}

$useCase->joinCompanyUseCase($employe);

$form->fillFromObject($employe)
    ->hydrate($person)
;

return new \Symfony\Component\HttpFoundation\JsonResponse($person);

The validation rules will be parsed from your entity class php attributes.
