Knop File Structure


Knop File Structure

All page requests pass through a central file

Types of include files:

- Config: configuration files

- Action: action logics (manipulation)

- Library: presentation logics (retrieval)

- Content: presentation

25


26


Knop Application Flow

Modules and file structure meet

Vital parameters:

- path: the current location on the site. “Where we are”.

- actionpath: how to take care of a form submission. “What to do”.

- actionpath is optional
