cakephp保存拖放列表订单到数据库

Question

我有一个列表，我想让用户重新排序列表。对于前端功能，我正在使用Uikit。该列表可以在前端重新排序，但是我很难弄清楚如何将列表顺序保存到数据库。 在表中，有一个“排序”行。因此，我要做的是根据用户订购列表的方式更新排序行。
我正在尝试通过通过其ID订单来完成此操作，然后我使用Ajax将数据发送给控制器。现在，当我重新排序列表时，响应为200个，有效载荷以用户设置的顺序显示项目ID和ID。我不知道该怎么做就是使用该数据更新数据库。我以为我可以循环浏览ID并将“排序”设置为循环的索引，但是我不确定如何在Cakephp中执行此操作。
我确定的另一件事是，如果我应该使用已经定义的列表方法，或者应该创建一种处理此功能的新方法。
任何帮助将不胜感激。 这就是我到目前为止的。
列表页面jQuery代码：

    UIkit.util.on('.uk-sortable', 'stop', function (item) {
    let ids = ""
    $('.uk-sortable tr').each(function() {
        id = $(this).attr('id'); //this is the project id
        if(ids =='') {
            ids = id;
        }else {
            ids = ids + ', '+id ;
        }
    });
    console.log($(this).data('id'));
    $.ajax({
        url:'admin/cost/list',
        type: 'POST',
        dataType: 'json',
        data: {
            'id': $(this).data('id'),
            'ids':'ids='+ids, 
        },
        success:function() {
          UIkit.notification(`sent successfully`, 'success');
        }

我能够解决我的问题。我将发布我的解决方案，谁知道这可能会帮助别人。
jQuery：

UIkit.util.on(".uk-sortable", "stop", function (item) {
  let ids = "";
  $(".uk-sortable tr").each(function () {
    id = $(this).data("id");
if (ids == "") {
  ids = id;
} else {
  ids = ids + ", " + id;
}
   // console.log(ids);
 });
 // console.log($(this).data('id'));
 $.ajax({
url: "/admin/cost/list-update/",
type: "GET",
dataType: "json",
data: {
  ids: "" + ids,
},
timeout: 10000,
 })
.done(function (result) {
  UIkit.notification(`リストの順序が正常に更新されました`, "success");
  //location.reload(true);
})
.fail(function (XMLHttpRequest, textStatus, errorThrown) {
