大家好，我正在制作一個注冊/登錄網站作為一個學習和練習專案，我正在使用一個教程：https ://www.youtube.com/watch?v=LC9GaXkdxF8&t=5768s&ab_channel=DaniKrossing
現在一切正常，我沒有收到任何語法錯誤，但是當我使用用戶名/電子郵件和密碼登錄時，它必須將我重定向到 ../index.php?login=success 頁面，但它沒有，它一直在index.php page.I 找不到您是否可以幫助我，我很高興收到你們的來信。
<?php
if (isset($_POST['login-submit'])) {
require 'dbh.inc.php';
$mailuid = $_POST['mailuid'];
$password = $_POST['pwd'];
if (empty($mailuid) || empty($password)) {
header("Location: ../index.php?error=emptyfields");
exit();
}
else {
$sql ="SELECT * FROM users WHERE uidUsers=? OR emailUsers=?;";
$stmt =mysqli_stmt_init($conn);
if (!mysqli_stmt_prepare($stmt, $sql)) {
header("Location: ../index.php?error=sqlerror");
exit();
}
else {
mysqli_stmt_bind_param($stmt, "ss",$mailuid, $mailuid);
mysqli_stmt_execute($stmt);
$result = mysqli_stmt_get_result($stmt);
if ($row = mysqli_fetch_assoc($result)) {
$pwdCheck = password_verify($password, $row['pwdUsers']);
if ($pwdCheck == false) {
header("Location: ../index.php?error=wrongpwd");
exit();
}
else if ($pwdCheck = true) {
session_start();
$_SESSION['userId'] = $row['idUsers'];
$_SESSION['userUid'] = $row['uidUsers'];
header("Location: ../index.php?login=success");
exit();
}
else {
header("Location: ../index.php?error=wrongpwd");
exit();
}
}
else {
header("Location: ../index.php?error=nouser");
exit();
}
}
}
}
else {
header("Location: ../index.php");
exit();
}
從現在開始非常感謝。

如果要使用頁眉，<?php ob_start();?>請在頁面頂部和頁面<?php ob_end_flush();?>底部鍵入。

驗證表單中提交的輸入型別是否具有以下屬性：
name="login-submit"&value="submit"
因為您可以重定向到的唯一方法index.php是：
if (isset($_POST['login-submit'])) // is FALSE
