php - 页面之间没有进行会话

Question

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，我应该携带登录用户的电子邮件，直到它注销，这是我的登录页面（login.php）。在表单操作中，我用一些键调用了一个 Web 服务，我已经将它转换为 json 格式，然后在发送到服务器时，我得到一个 json 格式的响应，该响应被解码并检查了一些条件（所有这些都发生在 profile.xml 文件中）。 php）根据条件的响应将它们重定向到另一个页面，检查它重定向到的页面是（pipm.php）。

login.php 是

<?php 
    session_start();
    ?>
    <html>
    <head>
    <title>LOGIN FOR PRODUCT MANAGEMENT</title>
    <link href="style.css" rel="stylesheet" type="text/css"/>

    <body>
    <div id="contact">

 HI <?php echo $_SESSION['username'];?>

在login.php表单中，动作将profile.php是这样的：

<form id="myForm1" action="profile.php" method="post">

在profile.php你没有设置任何$_SESSION变量。您需要将当前位于login.php顶部的这些行移至profile.php：

if (isset($_POST['Submit'])) {
    $_SESSION['username'] = $_POST['username'];
}
