I cannot saw where you did get the user submitted data. To do this, you must use:

Code:

$this->input->post('field_name');

If you want to keep the user submitted data for more than one request, you must store it in a session or pass them to the next request using flash variables. To store in a session, you must use:

Code:

$this->session->set_userdata('var_name',$data);

To get the session data, use:

Code:

$this->session->userdata('var_name');

Remember that CI session based on cookies do not store too much user data, since the session cookie can only store 4 KB. There are another options, like Native Session, based on PHP session engine.
