Dynamic Forms for Laravel

User-defined forms are a perennial problem for developers.

Dynamic Forms for Laravel gives you an easy solution: a drag-and-drop builder, an easy way to display the forms, and back-end validation to ensure the submitted data is good.

If you want to see it in action, here are some demo videos:

How does this work?

The front-end is powered by the open source Form.ioopen in new window JavaScript library. This is an awesome library: the builder is user-friendly, you can adjust what's offered, and add your own custom form fields.

On the backend, it's as simple as calling $request->validateDynamicForm(). It behaves just like the validateopen in new window method you're used to in Laravel, giving you valid data you can trust.

You do not need to use the Form.io SaaS platform. Your Laravel application is filling that role.

Concepts

There are a couple pieces to be aware of:

  • The form builder is a WYSIWYG editor that people use to create forms.
  • Form definitions are created & updated by the form builder. Definitions are JSON documents that describe a form's fields, validation logic, help text, etc.
  • Components are individual form fields. Formiojs comes with a wide variety of components, from basic <input type='text> fields to rich WYSIWYG textareas and API-backed address lookups. You can reconfigure existing components to create new ones, or write your own from scratch.
  • Forms are shown when you render a form definition. The form can be read-write or read-only (to display a submitted form). Forms produce submissions in the form of key:value JSON documents.

Supported Features

Formiojs offers a lot of functionality. Dynamic Forms for Laravel has implemented a limited subset of all its available features.

Most of the decisions not to include something were driven by what would give us a good minimum viable product. If there are missing features that you would like to see, please feel free to submit an issue to discuss including it.

Components

Most of the Formiojs components are supported in some configuration. These components have limitations:

  • Address only supports Open Street Maps
  • File only supports Amazon S3 and local storage (base64, dropbox, azure, and indexeddb support can be added)
  • Select only supports values, and not API-backed resources

These components are not supported at all:

  • HTML Element
  • Tags
  • Data Map
  • Data Grid
  • Edit Grid
  • Tree
  • Tabs
  • ReCAPTCHA
  • Nested Form

Scripting

Formiojs offers several methods for creating dependencies between form fields and calculating values: simple UI-driven setups, JSON Logic, and custom JavaScript.

Dynamic Forms for Laravel supports the simple UI-driven dependencies and JSON Logic.

No JS eval is supported.

Other Features

PDF forms and form wizards are not supported.
