$data = array('name' => $this -> input -> post('first_name') && $this -> input -> post('last_name'))
$this -> db -> insert('submits', $data)

Output: George Kurdahi

if you wold like to insert "George Kurdahi" string to DB you should concatinate string with .

$data = array('name' => $this->input->post('first_name') . " " . $this->input->post('last_name'))

Or if you have 'name' and 'surname' fields in DB:

$data = array('name' => $this->input->post('first_name'), 'surname' => $this->input->post('last_name'))
