<script type="text/javascript">

$(document).ready(function(){

    $('#editable').ckeip({
    e_url: 'site/abc',
    });



});// enf of the document ready function

I don't know the first thing about CodeIgniter or the underlying database library, but...

$this->db->where('id', 1);
$this->db->update('about', $up_data);

... seems kind of wrong. This looks like a query builder. Don't you need to chain the WHERE clause off of the UPDATE clause? Something like

$this->db->update('about', $up_data)->where('id', 1);

might work for you.

You could probably have found this out yourself with the most basic forms of troubleshooting, like echoing the new expected value, or querying the database after the update to ensure the update worked, or even breaking out a debugger.
