Question 1

How do I handle file uploads in CraueFormFlowBundle?

Accepted Answer

The bundle automatically Base64 encodes file uploads and stores them in the session by default. You can disable this feature or set a custom temporary directory in your flow class to manage performance, as detailed in the advanced section of the README.

Question 2

CraueFormFlowBundle vs Symfony's native form wizard options?

Accepted Answer

Symfony doesn't have a built-in multi-step form wizard; CraueFormFlowBundle provides a dedicated solution with features like dynamic step skipping and validation groups. In contrast, native Symfony would require custom implementation using sessions or events, which is more error-prone.

Question 3

How to skip steps conditionally based on user input?

Accepted Answer

Use the 'skip' option in the step configuration with a callable function that evaluates conditions, such as checking form data. The README's vehicle example shows skipping the engine step if the vehicle doesn't need one.

Question 4

Best practices for validation in multi-step forms with this bundle?

Accepted Answer

Utilize the per-step validation groups generated by the bundle, and customize them via form_options or by overriding methods in your flow class. The README explains how to set validation groups and avoid revalidating previous steps if needed.

Question 5

Can I use AJAX with CraueFormFlowBundle for smoother transitions?

Accepted Answer

While not natively supported, you can integrate AJAX by customizing form submissions with JavaScript and adjusting server-side logic. However, this requires extra effort beyond the bundle's standard server-side handling and may complicate the flow.

Question 6

How to customize the buttons and labels in the form template?

Accepted Answer

Pass variables like 'craue_formflow_button_class_last' or 'craue_formflow_button_label_finish' in the Twig template when including the buttons. The README provides examples with Bootstrap classes and custom labels for a tailored UI.
