$name            = $this->input->post('name');
$status            = $this->input->post('status');

$handphone        = $this->input->post('handphone');
$address        = $this->input->post('address');        

$data =  array (          'name'        =>  $name,
                         'status'            =>  $status,        
                         'email'        =>  $email,
