Question

我正在制作一个代码，系统会检查您是否是“管理员”。或者是“超级明星”。

我似乎无法让它循环一切，以检查是否＆＃39; SuperAdmin＆＃39;在＆＃39; user_type＆＃39;

$sql = "SELECT * from users";

$result = mysqli_query($con,$sql);

while ($row2 = mysqli_fetch_array($result)) {




if ($row2['user_type'] != "SuperAdmin") {

           echo "<script>window.alert('You do not have administrative 
priviledges for this page!');
              location.href='../admin_page.php';</script>";

    } else {

    }

}

Answer 1

window.alert（＆＃34;您没有此页面的管理权限！＆＃34;）; location.href =＆＃34; ../ admin_page.php＆＃34 ;;＆＃39 ;; } else { } ？＆GT;

Answer 2

我相信您要检查当前使用的是“管理员”还是“超级管理员”。在这种情况下，您需要使用在对用户进行身份验证后获得的UserID来获取当前用户的行。将您的查询和PHP代码更改为：

$UserId = 111; //This is the user id from database you get on authenticating the user: e.g. 111. 
$sql = "SELECT * from users WHERE UserId = ". $UserId;   
$result = mysqli_query($con,$sql); //This should retrieve a single row, with details for the specific user.
while ($row2 = mysqli_fetch_array($result)) {
if !(($row2['user_type'] == "SuperAdmin")||($row2['user_type'] == "Admin")){
           echo "<script>window.alert('You do not have administrative 
priviledges for this page!');
              location.href='../admin_page.php';</script>";

    } else {
          //Code to be executed if the user is an admin or a super admin
    }
}

你如何循环检查PHP中的文本
