I was wondering how to set-up the application parameters in the back-end to use them all around the application without the need of using the database and I came up with this solution, I hope it helps somebody else.
In this tutorial we will try to save cgridview filter(search) with title etc. basically we want to save two forms data i.e one represents filters and other data about filters like title, description etc. You can define your own structure for filter saving table here are some basic steps
I am writing this guide because I struggled to find a resource that included ALL of the necessary steps to completely separate the frontend from the backend. After reading guides like Configuring different sessions for backend and frontend in yii-advanced-app and yii2 configuring different sessions for backend and frontend in yii advanced application template, there are still steps missing. It is funny how the 2nd one says it is an extension of the first one's article. So I guess, my wiki guide here is yet a 3rd and more complete extension of both of them. I also found a few StackOverflow questions and blog posts regarding this topic. None of them fully worked, and must be missing some magic sauce!
