This extension provides extended form validations like client side form validation for the Contao forms.

Features
--------

[](#features)

- Client side form validation using . This is an commercial library supporting well known frameworks like Bootstrap, foundation. It is **NOT** included in this extension and has to be purchased and installed by its own.
- formvalidation.io supports html5 form validation. Since Contao supports html5 form field widgets most validators work out of the box.
- Automatically create frontend validators for:
    - upload file (extensions and file size)
    - password (min length of password field, compare passwords)
    - date formats (date, datim)
    - phone validator (formvalidation.io does not support input type tel.).
    - string length validation (min length, max length)

Following features are planned:

- Support default Contao 3.4 form syntax
- Provide extended [validators](http://formvalidation.io/validators/) for client and server side.
