Henrik Bjørnskov has a new post with a technique you can use to combine Symfony2 and Doctrine2 to create a multi-step form (a wizard) without having to worry about lost user information between steps.

The easy ways is doing it with Javascript and just show/hide the correct fieldsets when needed. The downside with this approach is that the data is only saved and validated once at the end. So if the user reloads the page the entered information is gone. The other way is to have every Step in the Wizard being a seperate form and validate the data based on what step you are on and save the necessary fields.

For his method, he created a Manager class with a StepInterface that returns the correct field names, forms and template information to render. The interface code is included in the post as well as an example of it in use setting up the wizard object, making a report and getting the correct step information from the wizard.
