php - How to keep logs of your users in Laravel 4? -

i have users table in database lay out :

• id
• username
• firstname
• lastname
• email
• photo

as of now, since admin user have admin right, , can create, update, , delete. want allow users have same right me later on. before release feature, want keep track on edit - things doesn't lost, , it's keep history of things.

what best practice feature ? know have programming logic in update function in controller function. know have create logs table on database store

• user_id : make change
• created_at : when change made
• old_data: string
• new_data: string

for someone, had experiences feature, can please give me advice ? appreciate concern. thank you.

i think best approach problem each action user takes want log should fire event.

event::fire('some.event', array(auth::user())); 

then can register listeners each event , log appropriately.

event::listen('some.event', function($user) {     // create new item in logs table here. });
