Question

我有一个链接到SQL数据库的下拉列表表。我有2张桌子。第一个是“ talent_table”，这是我试图通过下拉菜单进行编辑的表。第二张表是员工信息。

我正在尝试选择每个框，以将它们发布到另一个PHP文件中。问题是，这仅适用于最后一行（因为它是变量$ row中的最后一行）

如何通过POST从前几行中获取所选项目？

我尝试了在网上找到的各种解决方案，所有这些使我进入了现阶段。如果我只需要表中的一个下拉菜单，则可以使用该下拉菜单，但是由于在while循环中有while循环，因此找不到找到所选值的方法。

<html>
<?php
include_once 'db.php';
$menu   = "talent_table";
$menu2  = "staff_list";
$select = "2";
$res    = mysqli_query($conn, "SELECT * FROM $menu");
$res2   = mysqli_query($conn, "SELECT * FROM $menu2")
?>

<?php include 'style.css'?>

        function selectionFunc() {}

</body>
</html>

我希望能够在该列的任何下拉列表中更改一个值，并能够通过POST发送该值。

我只能通过POST发送下拉列表的最后一行。

下拉框表仅最后一行有效
