Return last inserted ID

[eluser]LuckyFella73[/eluser]
As far as I know you can access the last insert id from controller
direcly (after calling the model) without returning the id from
your model.

Code:

# controller:

// call you model
$this->addressbook_model->add_new_address();
// you don't need to write "$_POST" here
// POST data is available in your model

// and then (still controller)
$insert_id = $this->db->insert_id();

Is there a special reason why you try to return the
post data from your model back to tha controller? I mean, the post
data is available anyway.
