正如標題所暗示的那樣，我正在嘗試使用相同的 .php 頁面，并讓它在從特定位置重定向時顯示一些新內容。在上下文中...我有一個登錄名，在成功登錄后重定向到主頁，但如果不成功，則重定向到索引。有沒有一種方法可以讓我的索引頁面在從我的登錄頁面重定向后顯示“登錄錯誤”消息？這是我的登錄代碼...<?phpsession_start();include('conn.php');$query = "SELECT * FROM User";$result = mysqli_query($conn, $query) or die(mysqli_error($conn));if (isset($_POST["submit"])) { $logEmail = $conn->real_escape_string($_POST['logEmail']); $logPass = $conn->real_escape_string($_POST['logPass']); $checkuser = "SELECT * FROM User WHERE Email='$logEmail' AND UserPassword=AES_ENCRYPT('$logPass', 'MyKey')"; $userresult = mysqli_query($conn, $checkuser) or die(mysqli_error($conn)); $loginsucc = (mysqli_num_rows($userresult) > 0); if (mysqli_num_rows($userresult) > 0) { while ($row = mysqli_fetch_assoc($userresult)) { $userPriKey = $row['UserID']; $userid = $row['Email']; $accounttype = $row['IsAdmin']; $firstname = $row['FirstName']; $surname = $row['LastName']; $_SESSION['userPriKey'] = $userPriKey; $_SESSION['name'] = $firstname; $_SESSION['surname'] = $surname; $_SESSION['Email'] = $userid; $_SESSION['IsAdmin'] = $accounttype; if($accounttype == '1'){ header("Location: home.php"); }else if ($accounttype == '0'||$accounttype == NULL ) { header("Location: userhome.php"); } } } else { header("Location: index.php"); }}?>

在你調用之前header()設置一個會話變量
$_SESSION['msg'] = 'success you are logged in';
header('Location: page.php');
exit;
然后在 page.php 中，
session_start();
if (isset($_SESSION['msg'])) {
echo $_SESSION['msg'];
unset($_SESSION['msg']);
}
另外僅供參考，您應該使用準備好的語句。您的代碼并不完全安全
