PHP表单在while循环中进行MySQL更新

Question

我试图在网上寻找解决方案，但我不知道该如何提出。

line_id总是给出最后一个值，我知道它会被一会儿覆盖，但是我可以算出如何为mysql更新获取正确的id。我是否需要发布整个数组，或者我只是缺少一些简单的东西？

看了几个小时，在这里和那里换位，让我有些困惑。

        <form method="post">
                <?php 

                    if ($order_search->num_rows > 0) {
                    // output data of each row
                    $i=-1;
                    while ($detail = mysqli_fetch_array($order_search))
                    {

                    $i++;

                    $new_line_id[] = $detail[0];
