Firstly use code tags... come on.

Secondly are you referring to this line?

Code:
echo var_dump($this->input->post($data));

1) You do not need an echo before a var_dump statement.
2) This doesn't make sense. '$this->input->post($data)'

Code:
$data = array(  'first_name' =>$this->input->post('firstname'),

              'last_name'  =>$this->input->post('lastname'));

var_dump($data);

As Jason pointed out, some of your code just doesn't make any sense. However...

If you're getting 0's in the database, are your first_name and last_name fields the proper type? Varchar as opposed to int, for example?
