Database Update Question

[eluser]ehalber[/eluser]
Currently, I'm using a hidden form field to capture the id of the database record I want to update. Next I save the post vars in my controller and send them to my model. Is this the standard way to perform this operation? Are there alternative ways, better ways?

Code from controller

Code:

function update_news()
{

    $update_info = array(
                        'article' => $this->input->post('article'),
                        'order_date' => $this->input->post('order_date'),
                        'date' => $this->input->post('date')
                       );
  
    $id = $this->input->post('id');
  
    $this->Drift_model->update_entry($id, $update_info);

    redirect('admin/control_panel');
}

Code from model

Code:

function update_entry($id, $update_info)
{  
    $query = $this->db->update('news', $update_info, array('id' => $id));    
}

Thanks
