$emp_his_id = $this->input->post('eid');
$count_eid = count($emp_his_id);
for($i=0;$i<$count_eid;$i++)
{
$emp_his_pk = $emp_his_id[$i];
$inserte['company_name']= $this->input->post('cn');
$inserte['from_date']= $this->input->post('fd');
$inserte['to_date']= $this->input->post('td');
$inserte['type_of_buisness']= $this->input->post('tb');
$inserte['company_addres_lane_1']= $this->input->post('c1');
$inserte['company_addres_lane_2']= $this->input->post('c2');
$inserte['c_city']= $this->input->post('cc');
$inserte['c_pincode']= $this->input->post('cp');
$inserte['updated_on'] = date("Y-m-d");
$up_emp_history=$this->Frontend_model->update_employe($inserte=array(),$emp_his_pk);
}
}

Controller Code
You have to run a foreach loop in controller.
if ($this->input->post('advisor_update'))
{
$emp_his_id = $this->input->post('eid');
$cn = $this->input->post('cn');
$fd = $this->input->post('fd');
$td = $this->input->post('td');
$td = $this->input->post('tb');
$c1 = $this->input->post('c1');
$c2 = $this->input->post('c2');
$cc = $this->input->post('cc');
$cp = $this->input->post('cp');
foreach($emp_his_id as $key => $eid)
{
$emp_his_pk = $eid;
$inserte = array();
$inserte['company_name']= $cn[$key];
$inserte['from_date']= $fd[$key];
$inserte['to_date']= $td[$key];
$inserte['type_of_buisness']= $tb[$key];
$inserte['company_addres_lane_1']= $c1[$key];
$inserte['company_addres_lane_2']= $c2[$key];
$inserte['c_city']= $cc[$key];
$inserte['c_pincode']= $cp[$key];
$inserte['updated_on'] = date("Y-m-d");
$up_emp_history=$this->Frontend_model->update_employe($inserte=array(),$emp_his_pk);
}
}
Hope This works for you
