Codeigniter post data from declared variable - sql

Question

function index_post() {
$sql = "SELECT id_so FROM so_detail ORDER BY id_so DESC LIMIT 1";
$last_id2 = $this->db->query($sql)->result();
foreach ($last_id2 as $row) {
$last_id = $row->id_so;
}
//echo $last_id;
$data = array(
'id_so' => $this->post($last_id),
'id_product' => $this->post('id_product'),
'harga' => $this->post('harga'),
'harga_dasar'=> $this->post('harga'),
'modal' => $this->post('modal'),
'pajak' => $this->post('pajak'),
'qty' => $this->post('qty'),
'keterangan' => $this->post('keterangan'),
'create_user'=> $this->post('create_user'),
'create_time'=> $this->post('create_time'),
'update_user'=> $this->post('create_user'),
'update_time'=> $this->post('create_time'));
$insert = $this->db->insert('so_detail', $data);
if ($insert) {
$this->response($data, 200);
} else {
$this->response(array('status' => 'fail', 502));
}
}
i got a problem that the posted id_so is "null". when i echo $last_id it show correct id ex: 120. but when i call it to $this->post($last_id), it just be null..
How to post id_so with a string that already declared before ($last_id) ??

Answer 1

there are many array in $last_id2 variable.data will insert multiple time based on your last_id2.try this:
foreach ($last_id2 as $row) {
$data = array(
'id_so' =>$row->id_so,
'id_product' => $this->post('id_product'),
'harga' => $this->post('harga'),
'harga_dasar'=> $this->post('harga'),
'modal' => $this->post('modal'),
'pajak' => $this->post('pajak'),
'qty' => $this->post('qty'),
'keterangan' => $this->post('keterangan'),
'create_user'=> $this->post('create_user'),
'create_time'=> $this->post('create_time'),
'update_user'=> $this->post('create_user'),
'update_time'=> $this->post('create_time'));
}
$this->db->insert_batch('so_detail',$data);
