Answer 2

use codeigniter's tiny feature called Flashdata which allows you to have temorarily store data between requests.

so your code would be

function send data{
$this->session->set_flashdata('recordid', $recordid);
}

function success{
 $recordid =  $this->session->flashdata('recordid');
}

got it ?
