数据已在数据库中更新，但有错误

在我的系统中，我具有更新数据的功能。单击“更新”按钮后，数据将在数据库中更新，但它还会显示如下错误： PHP注意：未定义索引：C：\ inetpub \ wwwroot \ tgotworker \ pages \ manage_engineer_admin \ edit_engineer_admin.php中的badgeid

PHP注意：未定义的变量：C：\ inetpub \ wwwroot \ tgotworker \ pages \ manage_engineer_admin \ edit_engineer_admin.php中的全名

PHP注意：未定义变量：C：\ inetpub \ wwwroot \ tgotworker \ pages \ manage_engineer_admin \ edit_engineer_admin.php中的role_id

PHP注意：未定义变量：C：\ inetpub \ wwwroot \ tgotworker \ pages \ manage_engineer_admin \ edit_engineer_admin.php中的role_id

PHP注意：未定义的变量：C：\ inetpub \ wwwroot \ tgotworker \ pages \ manage_engineer_admin \ edit_engineer_admin.php中的team_id

PHP注意：未定义的变量：C：\ inetpub \ wwwroot \ tgotworker \ pages \ manage_engineer_admin \ edit_engineer_admin.php中的team_id

下面是我的代码：

$sql = "";
require_once "../../config/configPDO.php";
require_once "../../config/check.php";

if(isset($_POST['update']))
{   
  $badgeid = $_POST['badgeid'];

  // checking empty fields
  if(empty($badgeid)) { 

    if(empty($badgeid)) {
      echo "<font color='red'>Fac_Name field is empty.</font><br/>";
    }

  } else {  
    //updating the badgeid
    $sql = "UPDATE users SET roles_id = :roles_id, team_id = :team_id WHERE badgeid = :badgeid";
    $query = $conn->prepare($sql);

    $query->bindParam(':roles_id', $_POST['roles_id']);
    $query->bindParam(':team_id', $_POST['team_id']);
    $query->bindParam(':badgeid', $_POST['badgeid']);
    $query->execute();

    //redirectig to the display page. In our case, it is index.php
    header("Location: ../dashboard/dashboard_super_admin.php");
  }
}

//getting id from url
$badgeid = $_GET['badgeid']; //line 33

//selecting data associated with this particular id
$sql = "SELECT * FROM users LEFT JOIN roles on users.roles_id = roles.roles_id WHERE badgeid = :badgeid";
$query = $conn->prepare($sql);
$query->execute(array(':badgeid' => $badgeid));
$rows = $query->fetchAll(PDO::FETCH_ASSOC);
foreach($rows as $row)
{
  $badgeid = $row["badgeid"];;
  $fullname = $row["fullname"];
  $roles_id = $row["roles_id"];
  $team_id = $row['team_id'];
  $roles_name = $row["roles_name"];
}

$smt = $conn->prepare("SELECT * FROM team");
$smt->execute();
$data = $smt->fetchAll();
