Dynamic Form Bundle

Generates symfony forms based on YAML configuration files

Getting Started

This plugin supports Symfony ^2.8|^3.0|^4.0|^5.0. Even tough we encorage you to use the latest version because of the Symfony maintained branches itself.

The recommended way to install Linio Dynamic Form Bundle is through composer.

{
    "require": {
        "linio/dynamic-form-bundle": "~2.0"
    }
}

Tests

To run the test suite, you need install the dependencies via composer, then run PHPUnit.

$ composer install
$ vendor/bin/phpunit

Usage

Add the bundle on registerBundles() at AppKernel.php

new Linio\DynamicFormBundle\DynamicFormBundle();

The service dynamic_form.factory will be available.

Create your form on the Configuration File. The YAML structure for the Form should follow the next structure:

+---dynamic_form
|   \--- Form Name
|       \---Field Name
|           \---Field Options
|           \---Field Transformer
|           \---Field Validators

The method createform() takes the form configuration named new_user from app/config/config.yml.

use Linio\DynamicFormBundle\DynamicFormAware;

class TestController
{
	use DynamicFormAware;

	public function testAction()
	{
		$form = $this->getDynamicFormFactory()->createForm('new_user');
		return $this->render(
		  'WebBundle:Default:dynamicForms.html.twig',
		  ['form' => $form->createView(),]
		);
	}
}

The method getJsonConfiguration() takes the configuration from app/config/config.yml. and returns a JSON with the Form Configuration.

Example

Here's an example of a form named new_user with a single field called first_name:

dynamic_form:
    new_user:
        first_name:
            enabled: true
            type: text
            options:
                type: password
                required: true
            transformers:
            validators:

Options

Field options are the same as symfony, refer to the documentation

Transformers

When using transformers write both the class where it is defined and the calls you need.

dynamic_form:
    new_user:
        birthday:
            enabled: true
            type: text
            transformer:
              class: 'Linio\Frontend\CustomerBundle\Form\DataTransformer\BirthdayTransformer'
              calls:
                  - [setUserFormat, ['d/m/Y']]
                  - [setInputFormat, ['Y-m-d']]

Validators

When using validators call each validator constraint and its parameters like shown down below.

dynamic_form:
    new_user:
        first_name:
            enabled: true
            type: text
            validation:
              'Symfony\Component\Validator\Constraints\True':
                  message: 'The token is invalid.'
              'Symfony\Component\Validator\Constraints\Length':
                  min: 2
                  max: 50
