页面之间没有会话
[英]session not carrying between the pages
问题描述
i have created a login page here is the code ,i am not using any database and i am supposed to carry the email of the logged in user until it loggs out ,here is my login page(login.php) . 
我已经创建了一个登录页面，这里是代码，我没有使用任何数据库，并且应该携带登录用户的电子邮件，直到注销为止，这是我的登录页面（login.php）。 In the form action i have called a web service with some keys ,i have convereted it into json format and then on sending to server i get a response in json format which is decoded and after checking some condition(all these are happening in profile.php) they are redirected to another page based on the response of the condition check the page to which it is redirected is (pipm.php). 在表单操作中，我已调用带有某些键的Web服务，我将其转换为json格式，然后在发送到服务器时，得到json格式的响应，该响应被解码并检查了某些条件后（所有这些都在配置文件中发生。 php）根据条件的响应将它们重定向到另一个页面，检查该页面重定向到的页面是（pipm.php）。

In login.php the form action is going to profile.php as such: 在login.php ，表单操作将这样转到profile.php ：
<form id="myForm1" action="profile.php" method="post">
In profile.php you're not setting any $_SESSION variables. 在profile.php您没有设置任何$_SESSION变量。 You need to move these lines that are currently in login.php to the top of profile.php : 您需要将当前在login.php中的这些行移动到profile.php的顶部：
if (isset($_POST['Submit'])) {
$_SESSION['username'] = $_POST['username'];
}
