$this->load->library('pagination');

$c_paginate['base_url'] = site_url('record/index');
$c_paginate['per_page'] = '6';
$config['uri_segment'] = '3';

$query = $this->db->get_where('table', array('fieldname' => $field));

if ($query->num_rows() > 0) {
$i=0;
foreach ($query->result() as $row) {
$this->data['rec'][$i] =$row->field2;
$this->data['rec'][$i] = $row->field3;
$i++;
}
