Iterate a model's attributes within the model?

[eluser]peterphp[/eluser]
I found this code on another forum, it seems to solve the problem by excluding "_parent_name":

Code:

function get()
{
    foreach(get_class_vars(get_class($this)) as $key=>$value)
    {
        if($key != "_parent_name")
        {
            $val = $this->$key;
            if($val) $this->db->where($key, $val);
        }
    }
    // some more code here...
    }
}

Found this snipplet here.

Seems to me like the 'right' way to do it :-)
