я хочу подсчитать поле id = "HargaPart", если отмечено = true.
это мой код просмотра:

это мой контроллер:
function GetKendaraanById(){
$id_kendaraan=$this->input->post('id_kendaraan');
$data=$this->PemeliharaanModel->GetById($id_kendaraan);
echo json_encode($data);
}
это моя модель:
function GetById($id_kendaraan){
$this->db->select('*');
$this->db->from('tb_kendaraan');
$this->db->where('tb_kendaraan.id_kendaraan',$id_kendaraan);
$query_kendaraan = $this->db->get();
$hasil = false;
if($query_kendaraan->num_rows() > 0)
{
$data_kendaraan = $query_kendaraan->row();
$hasil = [
'tahun_beli' => $data_kendaraan->tahun_beli,
'id_jenis' => $data_kendaraan->id_jenis,
'id_merk' => $data_kendaraan->id_merk,
'spareparts' => [] // empty array, to be filled with spareparts data
];
$this->db->select('*');
$this->db->from('tb_sparepart');
$this->db->where('tb_sparepart.id_jenis', $data_kendaraan->id_jenis);
// $this->db->where('tb_sparepart.id_merk', $data_kendaraan->id_merk);
$query_sparepart = $this->db->get();
foreach ($query_sparepart->result() as $data_sparepart) {
$spareparts = [
'id_sparepart' => $data_sparepart->id_sparepart,
'sparepart' => $data_sparepart->sparepart,
'harga' => $data_sparepart->harga,
];
array_push($hasil['spareparts'], $spareparts);
}
}
return $hasil;
}
Сумма поле Харга
если я попробую этот код, результатом будет просто сумма HargaPart в запасной части "roda gede sekali" 500 + 500 = 1000, в этом коде должно быть 500 + 100 = 600, потому что я проверил 2 запасные части с not то же значение ...
как суммировать все value.harga если checkbox = true?
