Is there any useful links that can explain different options to achieve the Web Form implementation for a website build on SDL web8 + DXA 1.6 framework.
DXA 1.6 provides basic support for HTML Forms. See http://docs.sdl.com/LiveContent/content/en-US/SDL%20DXA-v6/GUID-2C331449-7CF4-4031-8080-85B3F478F700
This support includes:
- Support for managing form text (labels, validation messages) in CM
- Support for doing server-side validation and View Model mapping of form fields
- Support for preventing CSRF attacks
It does not include support for processing the form data. That is: you are expected to do that yourself in your implementation.
An example of HTML Form processing can be found in the Audience Manager module (see docs link above).
