I try to follow this link to install and create a form with CraueFormFlowBundle
CraueFormFlowBundle tutorial
i create the file
/src/AppBundle/Form/InterventoFlow.php
namespace AppBundle/Form;
use Craue\FormFlowBundle\Form\FormFlow;
use Craue\FormFlowBundle\Form\FormFlowInterface;
class InterventoFlow extends FormFlow {
protected function loadStepsConfig() {
return array(
array(
'label' => 'wheels',
'form_type' => 'AppBundle\Form\InterventoForm',
),
array(
'label' => 'engine',
'form_type' => 'AppBundle\Form\InterventoForm',
'skip' => function($estimatedCurrentStepNumber, FormFlowInterface $flow) {
return $estimatedCurrentStepNumber > 1 && !$flow->getFormData()->canHaveEngine();
},
),
array(
'label' => 'confirmation',
),
);
}
}
after i create
/src/AppBundle/Form/InterventoForm.php
<?php
/*

* To change this template file, choose Tools | Templates

*/
namespace AppBundle/Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\Extension\Core\Type\TextType;
class InterventoForm extends AbstractType {
public function buildForm(FormBuilderInterface $builder, array $options) {
switch ($options['flow_step']) {
case 1:
$validValues = array(2, 4);
$builder->add('numberOfWheels', 'Symfony\Component\Form\Extension\Core\Type\ChoiceType', array(
'choices' => array_combine($validValues, $validValues),
'placeholder' => '',
));
break;
case 2:
// This form type is not defined in the example.
$builder->add('engine', 'TextType', array(
'placeholder' => 'prova',
));
break;
}
}
public function getBlockPrefix() {
return 'createIntervento';
}
}
after i create the service
services:
app.form.InterventoFlow:
class: AppBundle\Form\InterventoFlow
parent: craue.form.flow
and the controller
public function interventoAction(Request $request)
{
$formData = new Validate(); // Your form data class. Has to be an object, won't work properly with an array.
$flow = $this->get('AppBundle.form.InterventoFlow'); // must match the flow's service id
$flow->bind($formData);
// form of the current step
$form = $flow->createForm();
if ($flow->isValid($form)) {
$flow->saveCurrentStepData($form);
if ($flow->nextStep()) {
// form for the next step
$form = $flow->createForm();
} else {
// flow finished
$em = $this->getDoctrine()->getManager();
$em->persist($formData);
$em->flush();
$flow->reset(); // remove step data from the session
return $this->redirect($this->generateUrl('home')); // redirect when done
}
}
return $this->render('interventi/intervento.html.twig', array(
'form' => $form->createView(),
'flow' => $flow,
));
}
and my twig file
{% extends 'base.html.twig' %}
{% block body %}
<div>
Steps:
{% include '#CraueFormFlow/FormFlow/stepList.html.twig' %}
</div>
{{ form_start(form) }}
{{ form_errors(form) }}
{% if flow.getCurrentStepNumber() == 1 %}
<div>
When selecting four wheels you have to choose the engine in the next step.<br />
{{ form_row(form.numberOfWheels) }}
</div>
{% endif %}
{{ form_rest(form) }}
{% include '#CraueFormFlow/FormFlow/buttons.html.twig' %}
{{ form_end(form) }}
{% endblock %}
{% stylesheets '#CraueFormFlowBundle/Resources/assets/css/buttons.css' %}
<link type="text/css" rel="stylesheet" href="{{ asset_url }}" />
{% endstylesheets %}
always give me error
Attribute "autowire" on service "app.form.intervento" cannot be inherited from "_defaults" when a "parent" is set. Move your child definitions to a separate file or define this attribute explicitly in C:\xampp\htdocs\Myprject\app/config\services.yml (which is being imported from "C:\xampp\htdocs\Myprject\app/config\config.yml").
and if i comment
parent: craue.form.flow
You have requested a non-existent service "app.form.interventoFlow".

Answer 1

Try to dalete _defaults section from your service.yml file.
