Question

我有一个php表单（称之为Home.php）和提交（方法Post），我有一个单独的PHP脚本验证信息（称之为Validate.php）。

验证后，会在Validate.php中初始化/设置会话变量。设置这些变量后，我将使用标题页中的标题（＆＃39;位置：home.php＆＃39;）重定向回home.php页面。

所有这一切都很完美，我可以访问会话变量并在home.php页面上显示它，但是一旦我点击刷新，变量值就会消失。即使我不刷新home.php，如果我转到服务器上的另一个页面并尝试访问会话变量，它们都是空白/未设置。

几点：我在所有页面和最开始都有Session_Start（）。会话保存路径配置值是/ tmp，这似乎不是问题，因为我可以在第一次尝试时设置和检索会话值，如上所述。

我搜索了Stackoverflow和谷歌，但无法找到任何东西。你是我最后的选择。希望有人可以帮助我。

提前致谢。

Home.php：：

<?php session_start();
  echo '<!DOCTYPE html>';
?>

And some HTML CODE HERE FOR DISPLAYING THE PAGE....

Answer 1

好的......这是我在代码中找到的内容，一旦我在此处发布。在Home.php的代码中有一个会话破坏，这就是导致所有这些Shenanigans的原因。

我删除了Session_Destroy（）和Onclick事件，这一切都完美无缺，就像它的设计一样。

感谢迈克和丹的时间。
