Question

刚刚编辑了php滑动jquery面板表单但它不起作用，实际注册工作但登录没有。我删除了一些与我的问题无关的代码......

请使用这种奇怪的语言忽略这些错误消息。

问题在于：

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

用户没有出现...我尝试了很多方法来解决它并猜测是什么？一切正常但在重定向到其他页面之后usr不存在...... CHMOD 755.它有什么问题？

Answer 1

正如session_name()所述，您必须设置会话名称 BEFORE 您调用session_start（）。您还在session_start()之后更改会话Cookie参数。

你不能这样做。在开始会话之前必须更改会话设置。

Answer 2

我怀疑你在开始之前处理会话可能是个问题。

PHP Session在我编辑的脚本中不起作用
