codeigniter success insert to database but failed to insert uploaded file - codeigniter

Question

I'm new here, so nice to meet you all.
I have trouble with codeigniter.
Maybe hard to tell so I will show all of my code :
my controller :
function upload_barang(){
$this->admin_model->login();
$this->admin_model->valid_product();
$config['upload_path'] = './produk/';
$config['allowed_types'] = 'jpg';
$config['max_size'] = '100';
$config['max_width'] = '400';
$config['max_height'] = '400';
$this->load->library('upload',$config);
$data['query'] = $this->db->get('kategori');
if($this->form_validation->run() == FALSE && ! $this->upload->do_upload()) {
$data['error'] = $this->upload->display_errors();
$data['success'] = '';
$this->load->view('backoffice/tambahbarang',$data);
} else {
$upload_data = $this->upload->data();
$data['error'] = '';
$data = array(
'idkategori' => $this->input->post('idkategori'),
'namabarang' => $this->input->post('nbarang'),
'image' => $upload_data['file_name'],
'status' => 1
);
$data_insert = $this->db->insert('barang',$data);
if($data_insert == TRUE) {
$data['query'] = $this->db->get('kategori');
$query = $this->db->get('barang');
$rows = $query->row();
$data['idbarang'] = $rows->idbarang;
$harga = array(
'idbarang' => $data['idbarang'],
'satuan' => $this->input->post('stcbarang'),
'harga' => $this->input->post('hbarang')
);
$this->db->insert('hargabarang',$harga);
$data['success'] = '<b>Barang Telah Ditambahkan</b>';
$this->load->view('backoffice/tambahbarang',$data);
} else {
$data['success'] = '<b>Barang Gagal Ditambahkan</b>';
$this->load->view('backoffice/tambahbarang',$data);
}
}
}
This code success insert all of data to database, except on column 'image' that I fill with '$upload_data['file_name']' this empty on my database.
what's wrong with my code?
please help thanks

You can use this format:
/*
* ------- Start Image Upload---------
*/
$config['upload_path'] = 'image/product_images/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '400';
$config['max_height'] = '400';
$this->load->library('upload', $config);
$this->upload->initialize($config);
$error='';
$fdata=array();
if ( ! $this->upload->do_upload('product_image'))
{
$error = $this->upload->display_errors();
echo $error;
exit();
}
else
{
$fdata = $this->upload->data();
$data['product_image']=$config['upload_path'] .$fdata['file_name'];
}
/*
* --------End Image Upload---------
*/
$this->super_admin_model->save_product_info($data);
