README

Framework-agnostic form-builder engine for Contenir CMS.

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

composer require contenir/formbuilder

Optional but commonly paired:

• contenir/storage — required for the file field type, passed in to FormSubmissionService.

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,
