Javascript 如何使用php获取select2的多个选定值

我正在尝试保存多个select2 我的桌子看起来像这张照片

表行本身将由javascript在运行时创建

function addRow_tugas_rkb(tableID) {
   var table = document.getElementById(tableID);
   var rowCount = table.rows.length - 2;
   var row = table.insertRow(rowCount);
   var cell6 = row.insertCell(0);
   var cell5 = row.insertCell(0);
   var cell4 = row.insertCell(0);
   var cell3 = row.insertCell(0);
   var cell2 = row.insertCell(0);
   var cell1 = row.insertCell(0);

    cell1.innerHTML="<button type='button' onclick='delRow_tugas_rkb(this)' style='width:25px;height:25px;font-size:15px;' class='btn btn-floating btn-danger btn-sm'><i class='icon icon fa-minus' aria-hidden='true'></i></button>";


   var element2 = document.createElement("textarea");
   element2.className="form-control ket_rkb";
   element2.name = "ket_rkb[]";
   element2.rows = "2";
   element2.cols = "70";
   cell2.appendChild(element2);

   var element3 = document.createElement("input");
   element3.className="form-control bobot_rkb";
   element3.type = "text";
   element3.style.width = "45px";
   element3.name = "bobot_rkb[]";
   element3.onchange=hitung_bobot;
   cell3.appendChild(element3);

    var element4 = document.createElement("input");
    element4.className="form-control target_rkb";
    element4.type = "text";
    element4.style.width = "45px";
    element4.name = "target_rkb[]";
    cell4.appendChild(element4);

我的问题是：

select2 multiple not working，如何使用多个数据循环select2

当我保存在表中时，如下所示

我想要这样的结果

我的代码有什么问题。。 谁能帮帮我吗

抱歉，我的英语不好

您可以在save.php文件中打印$\u POST变量，以验证是否在save.ph文件中收到数据。@sachinaghav我已经上传了一张新照片，希望您能理解我的意思…您可以使用

$\u POST['nrk\u turunan']

获得所选值，因为它是一个数组，所以您必须对它进行迭代或将其转换为可用格式。@MayankPandeyz是的，我使用foreach$_POST['nrk_turunan']获取值，但它不起作用，在每个不同的id中，总是插入所有选中的行，如上面的示例照片。你可以看到我的代码，怎么了？请帮帮我。。
