Send array multidimension with ajax-CodePudding

I have some issues with sending a multidimensional array with a ajax request to a php server.

So, I have multidimensional array on client side, when I send that array to php server side, array is received as string

My code like this

 let data_barang = [];
        var nama_barang = $("#nama_barang_add").val();
        var id_barang = $("#nama_barang_add").data("id_barang");
        var perkiraan = $("#nama_barang_add").data("perkiraan");

        var qty = $("#qty_add").val();
        var satuan = $("#satuan_add").val();

        data_barang.push([nama_barang, qty, satuan, id_barang, perkiraan]);

                    $.ajax({
                    url: '<?= base_url("Admin/Pengadaan/tambahSPB") ?>',
                    type: 'POST',
                    dataType: 'json',
                    data: {
                        id_rab: id_rab,
                        tgl_order: tgl_order,
                        id_supplier: id_supplier,
                        kode_supplier: kode_supplier,
                        alamat_supplier: alamat_supplier,
                        nama_supplier: nama_supplier,
                        provinsi_supplier: provinsi_supplier,
                        data_barang: data_barang // data barang is multidimensional array
                    },
                    success: function(data) {
                        alert(data.data_barang);
                    }

This code on server side :


 $data_barang[] = $this->request->getPost("data_barang");
 $dataStatus = [
            "message" => $message,
            "detail" => $data_detail,
            "data_barang" => $data_barang
        ];

        echo json_encode($dataStatus);

i try use json.stringifiy on client side and on server side i use json_deocode, but is not work

somebody can help me? Thaks

CodePudding user response：

convert your array to string with JSON.stringify

data: {
  id_rab: id_rab,
  tgl_order: tgl_order,
  id_supplier: id_supplier,
  kode_supplier: kode_supplier,
  alamat_supplier: alamat_supplier,
  nama_supplier: nama_supplier,
  provinsi_supplier: provinsi_supplier,
  data_barang: JSON.stringify(data_barang) // data barang is multidimensional array
}

you can check array with

$data =  json_decode($_POST['data_barang']);
print_r($data);
