Hey guys, I am working on one of my first web apps. It will have a few pages 5 or so that are all front end, this will be the main site. Then there will be an admin area with pages to update content on the front end pages. I am a bit unclear on how to proceed. Should I create on controller, i.e. site_main with functions for each of the main pages? Each with a model? Should I create seperate controllers for each of these pages? I also need to be able to allow the admin to create pages, should this be in its own controller? Thanks a ton, sorry for all the questions. I am new to MVC and CI..
