How it works

Each page in Kohanut has one or more Content Areas and these areas hold Blocks with represent different Elements.

Execution starts with Controller_Kohanut->action_view(). Lets say we request the page "about". Kohanut looks in the database for a page with that url.

kohanut_pages table

It looks like the page "about" has an id of 8 and layout number 2. Kohanut_Page->render() is called, which finds the layout:

kohanut_layouts table

Kohanut_Layout->render() is called, which parses the code through Twig. The navs, breadcrumbs, snippets, and content areas are drawn. For example, if the layout has the line {{ Kohanut.content_area(1,'Main Column') }}, we will look in the blocks table for elements on this page and this area:

kohanut_blocks table

We would then find which elementtype id 1 and 2 are.

kohanut_elementtypes table

We then try to find the classes Kohanut_Element_Content and Kohanut_Element_Request, and pass them the ids from the kohanut_blocks table, and each elements render() function is called.
