                $save_data['name'] =$data->val($i,1);
                $save_data['slug'] =$data->val($i,2);
                $save_data['about_us'] =$data->val($i,3);
                $save_data ['status'] = 1;

                if(!$this->Company_model->__insert('ph_companies',$save_data)){
                    $this->session->set_flashdata('error', 'Record couldn\'n inserted. Please try again.');
                }
                else{
                    $this->session->set_flashdata('success', 'companies  data created.');
                    //redirect('admin/company');
                }
            }

            unlink($_FILES['filepegawaiall']['name']);
        }
        $this->load->view('admin/template/header');
        $this->load->view('admin/company/import',$this->data);
        $this->load->view('admin/template/footer');
