使用 js 将 Item 数据值传递给控制器

Question

您好，我的项目有问题，我尝试使用 JSON，但我有多个变量，所以我不知道它是否有效，当我尝试将 $id 传递到控制器快照并使用 mysql 项目数据调用数据时，数据为空。 我被困在这里

这是我的看法

<div class="row">
<table class="table mt-3" id="t_detail">
    <thead class="thead">
        <tr>
        <th scope="col">#</th>
        <th scope="col">Gambar</th>
        <th scope="col">Nama Barang</th>
        <th scope="col">Harga</th>
        </tr>
    </thead>
    <tbody>
        <?php $no=0;foreach ($produk as $id=>$prd): ?>
            <?php $no++?>
        <tr>
            <?php $barang []= array(
                'id' => $prd->id_barang,
                'quantity' => 1,
                'price' => $prd->harga,
                'name' => $prd->nama_barang,
            );?>
        <th scope="row"><?=$no?></th>
        <td><img height="280" width="auto" src="<?=base_url('uploads/' . $prd->gambar)?>" ></td>
        <td><?=$prd->nama_barang?></td>
        <td>Rp. <?php echo number_format($prd->harga,0,",",".");?></td>
        </tr>
        <?php endforeach;?>
        <?php $no++?>
        <tr>
        <th scope="row"><?=$no?></th>
        <td></td>
        <td>Biaya Ongkir</td>
        <td>Rp. <?php echo number_format($transaksi->ongkir,0,",",".");?></td>
        </tr>
    </tbody>
    <tfoot>
    <tr>
        <th scope="row"></th>
        <td></td>
        <td>Total Bayar</td>
        <td>Rp. <?php echo number_format($transaksi->total_bayar,0,",",".");?></td>
        </tr>
    </tfoot>
    </table>
</div>
<?php if ($produk):?>
    <div class="row">
    <div class="col-md-6 offset-md-6">
    <button class="btn btn-sm btn-success float-right" id="tombol-bayar">Bayar</button>
    </div>
</div>
<?php endif;?>
<input name="transaksi_id" value="<?=($transaksi->id)?>" type="hidden">
<input name="nama" value="<?=($transaksi->namalengkap)?>" type="hidden">
<input name="alamat" value="<?=($transaksi->alamat)?>" type="hidden">
<input name="kodepos" value="<?=($transaksi->kodepos)?>" type="hidden">
<input name="kabupaten" value="<?=($transaksi->kabupaten)?>" type="hidden">
<input name="no_hp" value="<?=($user['no_hp'])?>" type="hidden">

和我的 JS

<script>
    $('#tombol-bayar').click(function(event) {

        var transaksi_id = $("input[name=transaksi_id]").val();
        var nama = $("input[name=nama]").val();
        var alamat = $("input[name=alamat]").val();
        var email = $("input[name=email]").val();
        var kodepos = $("input[name=kodepos]").val();
        var ongkir = $("input[name=ongkir]").val();
        var ekspedisi = $("input[name=ekspedisi]").val();
        var paket = $("input[name=paket]").val();
        var kabupaten = $("input[name=kabupaten]").val();
        var no_hp = $("input[name=no_hp]").val();
        var total_bayar = $("input[name=total_bayar]").val();

        $(this).attr("disabled", "disabled");

        $.ajax({
            type: "POST",
            url: '<?= base_url() ?>/snap/token',
            cache: false,
            data: {
                barang: barang,
                'transaksi_id': transaksi_id,
                'nama': nama,
                'alamat': alamat,
                'email': email,
                'kodepos': kodepos,
                'ongkir': ongkir,
                'ekspedisi': ekspedisi,
                'paket': paket,
                'kabupaten': kabupaten,
                'no_hp': no_hp,
                'total_bayar': total_bayar,
            },

            success: function(data) {
                //location = data;

                console.log('token = ' + data);

                var resultType = document.getElementById('result-type');
                var resultData = document.getElementById('result-data');

                function changeResult(type, data) {
                    $("#result-type").val(type);
                    $("#result-data").val(JSON.stringify(data));
                    //resultType.innerHTML = type;
                    //resultData.innerHTML = JSON.stringify(data);
                }

                snap.pay(data, {

                    onSuccess: function(result) {
                        changeResult('success', result);
                        console.log(result.status_message);
                        console.log(result);
                        $("#payment-form").submit();
                    },
                    onPending: function(result) {
                        changeResult('pending', result);
                        console.log(result.status_message);
                        $("#payment-form").submit();
                    },
                    onError: function(result) {
                        changeResult('error', result);
                        console.log(result.status_message);
                        $("#payment-form").submit();
                    }
                });
            }
        });
    });

和我的控制器

 public function token()
{

    $nama = $this->input->post('nama');
    $email = $this->input->post('email');
    $kabupaten = $this->input->post('kabupaten');
    $kodepos = $this->input->post('kodepos');
    $alamat = $this->input->post('alamat');
    $no_hp = $this->input->post('no_hp');
    $ekspedisi = $this->input->post('ekspedisi');
    $paket = $this->input->post('paket');
    $ongkir = $this->input->post('ongkir');
    $total_bayar = $this->input->post('total_bayar');
    $barang = $this->input->post('barang');

    $item_details [] = $barang;

我如何将项目数据发布到该控制器中..我很困惑请帮助
