Laravel: performing some task on every insert/update when using Query Builder or Eloquent ORM

Question

The Problem

I would like to automatically add created_by and modified_by fields to every insert/update to a database table in Laravel 4,

You must never override the save method to override and add your functionnality.

You have to use the Model Events functionnality that eloquent provides to do that instead.

To put it simply, you have to define a saving event for you model to override/set/check data that the model is going to save.

A simple example to put in a User model class:

//Executed when loading model
public static function boot()
{
     parent::boot();

     User::creating(function($user){
         $user->value1 = $user->value2 +1;
     });
}
