如何在codeigniter中获取数组内的购物车数据

Question

我的购物车会议中有2件商品。并希望我在数组 data_order 中合并。但只读一个产品。实际上我将通过电子邮件发送这些数据，因此我制作了这样的数据格式。

我的控制员：

foreach ($this->cart->contents() as $item){

    if($item['diskon'] == "0"){
        $harga_before = $item['before'];
        $harga_after = $item['price'];
    }else{
        $harga_before = $item['before'];
        $harga_after = $item['price'];
    }

    foreach ($this->cart->product_options($item['rowid']) as $option_name => $option_value){
        if(empty($option_value)){
            $option_size = "";
            $option_color = "";
        }else{
            $option = $item['options'];
            $option_size = $option['Size'];
            $option_color =  $option['Warna'];
        }
    }

        $data = array(
            'inv'        => $invoice,
            'tglOrdercs' => date('d F Y H:i:s'),
            'tglExp'     => $date_maju,
            'nmlkp'      => $nmlkpi,
            'almtkp'     => $address,
            'noTelp'     => $notelp271,
            'methode'    => $method,
            'bnk_option' => $banking_select,
            'data_order' => array(
                            'nama_produk'   => $item['name'],
                            'artikel'       => $item['artikel'],
                            'diskon'        => $item['diskon'],
                            'ukuran'        => $option_size,
                            'warna'         => $option_color,
                            'qty'           => $item['qty'],
                            'harga_fix'     => $harga_after,
                            'harga_before'  => $harga_before,               
                        ),
        );
    }

我的结果：

Array(
[inv] => STJOHB9261JR
[tglOrdercs] => 28 September 2017 11:23:33
[tglExp] => 28 September 2017 21:23:33
[nmlkp] => danny setyawan
[almtkp] => Perum puspa sari H22 sidoarjo
[noTelp] => 089263423647
[methode] => Transfer
[bnk_option] => Bank BNI
[data_order] => Array
    (
        [nama_produk] => Sonic TL Brown
        [artikel] => CH2002-831
        [diskon] => 40
        [ukuran] => 39
        [warna] => Coklat
        [qty] => 2
        [harga_fix] => 125340
        [harga_before] => 208900
    )

）

忽略“＆gt;”，这是浏览器控制台的结果。
