Re: Confusion with $this->data and $this->alias as used in this function...

Thanks Miles!

I follow you on $this->alias but where does $password_field come from. I'm searching everywhere to find something on this.

$this->alias is the name of the model. If your model is User, then you
must do that on $data to get the correct value.

$data['User']['password'] is equivalent to:
$data[$this->alias][$password_field] which is the better approach
because its dynamic.
