PHP會話在我編輯的腳本中不起作用

Question

剛剛編輯了php滑動式jquery面板表單，它不起作用，實際上注冊有效，但登錄無效。 我刪除了一些與我的問題無關的代碼...

請以這種奇怪的語言忽略這些錯誤消息。

問題是在這里：

    <li>Witaj <?php echo $_SESSION['usr'] ? $_SESSION['usr'] : 'Gościu';?>!</li>

用戶未出現...我嘗試了多種方法來修復它並猜測是什么？ 一切正常，但是重定向到其他頁面usr后不存在... CHMOD755。這是什么問題？

Answer 1

如session_name（）所述 ， 必須 在調用session_start（） 之前設置會話名稱。 您還將在AFTER session_start()之后更改會話cookie參數。

你不可以做這個。 在開始會話之前，必須更改會話設置。

Answer 2

我懷疑您是在開始之前進行會話的，這可能是問題所在。
