2. Using storage¶

2.1. Storing data with default storage¶

By default, flow bundle will use session for data storage. Here is simple example how to use it in your steps:

<?php

namespace Acme\DemoBundle\Process\Step;

use Sylius\Bundle\FlowBundle\Process\Context\ProcessContextInterface;
use Sylius\Bundle\FlowBundle\Process\Step\ControllerStep;

class FirstStep extends ControllerStep
{
    // ...

    public function forwardAction(ProcessContextInterface $context)
    {
        $request = $this->getRequest();
        $form = $this->createForm('my_form');

        if ($request->isMethod('POST') && $form->bind($request)->isValid()) {
            $context->getStorage()->set('my_data', $form->getData());

            return $this->complete();
        }

        return $this->render('AcmeDemoBundle:Process/Step:first.html.twig', array(
            'form' => $form->createView(),
        ));
    }
}

You can later get data with $context->getStorage()->get('my_data').
