contenir/formbuilder
====================

[](#contenirformbuilder)

Framework-agnostic form-builder engine for [Contenir CMS](https://github.com/contenir).

Provides the runtime-editable form-definition value objects, the registry of field types, the curated validator vocabulary, the conditional-visibility rule engine, and the build/submit services that turn a stored definition into a working `Laminas\Form\Form` and a validated submission.

This package is the pure-PHP core. It has no opinion about how form definitions are loaded (DB, JSON, hardcoded array — bring your own loader) or how submissions are stored (registrar pattern). Adapter packages such as `contenir/formbuilder-laminas-mvc` wire it into a host framework.

Install
-------

[](#install)

```
composer require contenir/formbuilder
```

Optional but commonly paired:

- [`contenir/storage`](https://github.com/contenir/storage) — required for the `file` field type, passed in to `FormSubmissionService`.

Layout
------

[](#layout)

Usage

[](#usage)

```
use Contenir\FormBuilder\Definition\FormDefinition;
use Contenir\FormBuilder\FieldType\FieldTypeRegistry;
use Contenir\FormBuilder\Service\FormBuilderService;
use Contenir\FormBuilder\Service\FormSubmissionService;
use Contenir\FormBuilder\Validator\ValidatorFactory;

$registry = new FieldTypeRegistry();
$validators = new ValidatorFactory();

$builder = new FormBuilderService($registry, $validators);
$form    = $builder->build($definition);  // Laminas\Form\Form

$service = new FormSubmissionService($builder);
$service->attach($yourPersistenceObserver);
$result = $service->submit($definition, $_POST, $_FILES, [
    'ip'      => $_SERVER['REMOTE_ADDR'] ?? null,
    'user_id' => null,
    'meta'    => [],
