我已经搜索了很多以找到这个问题的解决方案，但还没有成功。我正处于一个项目，管理员必须批准从数据库列出的注册用户。基本上我的问题是如何在提交时使所选用户（来自复选框），在数据库字段中设置1＆＃39;状态＆＃39;。我无法弄清楚如何处理代码。
我是网络开发的新手。在这里，我发布了我正在工作的页面的代码：

$module_id = '';
$query = '';

$date_to = '';

$sqlQuery = "SELECT * FROM tbl_user WHERE type =3 " ;
if(isset($_GET['users'])){
$users=$_GET['users'];
}else{
$users='';
}
switch ($users)
{
case "all":
$sqlQuery = "SELECT * FROM tbl_user WHERE type =3";
break;
case "approved":
$sqlQuery = "SELECT * FROM tbl_user WHERE type =3 AND status =1";
break;

$sqlQuery = "SELECT * FROM tbl_user WHERE type =3 AND status =0";
break;
