Introduction

Allows you to generate Symfony forms using YAML, JSON or associative array configurations based on the standard configurations of the framework's forms component.

See: https://symfony.com/doc/current/reference/forms/types.html

It is based on the use of the add function of the form builder used to create forms with Symfony

1. el name para el input de formulario
2. el tipo de campo de formulario
3. un array de options para configurar este tipo de campo

// FormInterface::add($child, string $type = null, array $options = [])
$builder->add($inputName, $inputTypeClass, $inputOptions);

With this it is possible to create a YAML configuration, JSON or an associative array in which:

• the key represents the $inputName
• type represents a form $inputTypeClass supported by the
• bundle or the "fully qualified class name (FQN)" of a class form type
• the options array represents the form $inputOptions

This allows you to configure forms dynamically by using yaml, json or an associative array like the examples below:

YAML

name:
birthday:
  type: date
  options:
    label: 'Your Birthday'
status:
  type: choice
  options:
    choices:
      Active: A
      Inactive: I
custom_type:
  type: App\Form\Type\CustomType
  options:
    custom_option: value

JSON

{
  "name": null,
  "birthday": {
    "type": "date",
    "options": {
      "label": "Your Birthday"
    }
  },
  "status": {
    "type": "choice",
    "options": {
      "choices": {
        "Active": "A",
        "Inactive": "I"
      }
    }
  },
  "custom_type": {
    "type": "App\\Form\\Type\\CustomType",
    "options": {
      "custom_option": "value"
    }
  }
}

PHP

$formConfig = [
  'name' => NULL,
  'birthday' => [
    'type' => 'date',
    'options' => [
      'label' => 'Your Birthday',
    ],
  ],
  'status' => [
    'type' => 'choice',
    'options' => [
      'choices' => [
        'Active' => 'A',
        'Inactive' => 'I',
      ],
    ],
  ],
  'custom_type' => [
    'type' => 'App\\Form\\Type\\CustomType',
    'options' => [
      'custom_option' => 'value',
    ],
  ],
]

Installation

composer require micayael/form-generator-bundle

Usage

Where it is necessary to create a form, for example a controller or a service, you must inject the FormGenerator object provided by the bundle.

class HomeController extends AbstractController
{
    /** @required */
    public FormGenerator $formGenerator;

    public function __invoke(Request $request): Response
    {
        $formConfigArray = []; // configuration as associative array

        // Gets a FormInterface object with the configured form
        $form = $this->formGenerator->createForm($formConfigArray);

        $form->handleRequest($request);

        if($form->isSubmitted() && $form->isValid()){
            $formData = $form->getData();

            // process your form
        }
    }

The FormGenerator service provides the following methods:

1. FormGenerator::createForm(array $formConfig, array $formOptions = [], $data = null, string $baseFormTypeClass = null, string $groupName = null): Creates a form from an associative array
2. FormGenerator::createFormFromJson(string $formConfigJson, array $formOptions = [], $data = null, string $baseFormTypeClass = null, string $groupName = null): Creates a form from a json string
3. FormGenerator::createFormFromYaml(string $formConfigYaml, array $formOptions = [], $data = null, string $baseFormTypeClass = null, string $groupName = null): Creates a form from a yaml string

Method arguments

1. array $formConfig: form configuration
2. array $formOptions = []: custom form options
3. $data = null: form data
4. string $baseFormTypeClass = null: Form class (FQN) that will be used as the base to add the other fields. If not passed, they are added to an empty form.
5. string $groupName = null: name that will be used to group the fields created by the $formConfig argument as an embeded form
