使用codeigniter在foreach循环php上复制值

Question

我有一个表格，我将在数据库中迭代摩托车模型列表，其中空白字段用户将输入机箱和发动机型号。问题是当我提交表单时数据被复制到数据库中。有什么想法吗？

视图

for ($i = 1; $i <= $quantity; $i++) {

echo "<tr><input type='hidden' class='input-xlarge' name='order_id[]' id='id' value='$order_id'>             
      <td class='text-center'><input type='hidden' class='input-xlarge' name='model[]' id='model' value='$row->model'>$row->model</td>
      <td class='text-center'><input type='hidden' class='input-xlarge' name='color[]' id='color' value='$row->color'>$row->color</td>
      <td class='text-center'><input type='hidden' class='input-xlarge' name='quantity[]' id='quantity' value='1'>1</td>
      <input type='hidden' class='input-xlarge' name='quantity_received[]' id='quantity_received' value='1'>
      <td class='text-right'><input type='text' class='input-xlarge' name='engine_no[]' id='engine_no' value='$engine_no' placeholder='Engine No'></td>
      <td class='text-right'><input type='text' class='input-xlarge' name='chassis_no[]' id='chassis_no' value='$chassis_no' placeholder='Chassis No'></td>
        </td>
      <td class='text-right'><input type='text' class='input-xlarge' name='promo[]' id='promo' value='$promo'></td>
      <input type='hidden' class='input-xlarge' name='unit_cost[]' id='unit_cost' value='$unit_cost'>
    </tr>";

}

$this->load->model('purchase_order');
