我無法在更改密碼頁面中將密碼更新為新密碼，而且完全沒有錯誤，所以找不到哪個是不正確的部分。我檢查了 MySQL 表，它沒有更新。有人可以幫忙查一下嗎？謝謝。PHP代碼 include "../setting/config.php"; session_start();$btnchange = filter_input(INPUT_POST, "btnchange");if(isset($btnchange)){ $username = filter_input(INPUT_POST, "username"); $password = filter_input(INPUT_POST, "password"); $query2 = "SELECT username from registered_accounts where username='$username'AND password='$password'"; $query_run=mysqli_query($conn, $query2); $level = mysqli_fetch_array($query_run); if(count(fetchAll($query2)) > 0){ //this is to catch unknown error. foreach(fetchAll($query2) as $row){ if ($row['username'] == $username && $row['password'] == $password) { $update_query2= "UPDATE registered_accounts set password='$password' where username='$username'"; $update_query_run=mysqli_query($conn, $update_query2); if ($update_query2) { echo "<script>alert('Password has been changed successfully.')</script>"; } else{ echo "<script>alert('Password has been failed to change.')</script>"; }}}}}?>身體<form action="<?= $_SERVER['PHP_SELF'] ?>" method="post"> <input type="text" class="text" name="username" placeholder="Username" value="" required autofocus> <input type="password" placeholder="Password" name="password" value="" required autofocus> <div class="submit"><input type="submit" value="Submit" name="btnchange"></div></form>注冊賬戶表

您需要更新此新密碼。并且這個新密碼不是被查詢用戶的當前密碼。因此選擇查詢無法檢索任何結果。從 $query2 中刪除 AND password='$password'，如下所示：
$query2 = "SELECT username from registered_accounts where username='$username'";
并刪除 if 語句，因為不需要再次檢查。
if ($row['username'] == $username && $row['password'] == $password)
希望這會有所幫助，但我也建議您使用準備好的語句來防止 SQL 注入。
