Question

deactivate_myaccount.php中的代码运行一次然后在顶部出现错误 - “注意：会话已经启动 - 忽略C：\ xampp \ htdocs \ includes \ includes \ header-inc中的session_start（）第2行的.php“。此外，此代码应该将DB中的“已关闭”字段更改为“是”，以便此人无法登录，但这不会发生。我相信会议正在进行中。当我使用相同的详细信息重新登录时，系统允许我登录，然后当我选择“停用帐户”按钮时，它只是说“您必须登录才能查看此页面！”并且不会显示表单以供我停用。

Deactivate_myaccount.php
    <?php
    session_start();
    if (!isset($_SESSION["user_login"])) {
       header("Location: sign_up.php");
    } else {
          $username = $_SESSION["user_login"];
    }


    include ("includes/header-inc.php");

    ?>

    <h2> Deactivate Account: </h2>

    <?php
    //Taking the user back
    $email = "";
    if ($email) {
        if(isset($_POST['no'])){
            header ("Location: includes/profile_student.php");
            }
    if (isset($_POST['yes'])){
        $deactivate_acc = mysqli_query("UPDATE users SET closed = 'yes' WHERE email = '$email'");
        echo "You account has now been deactivated! Sorry to see you leaving MYASTONSPACE";
        session_destroy();
    }
    }
    else {

        die ("You must be logged in to view this page!");   

        }

    ?>

Answer 1

如果您的电子邮件始终是$email = ''，并且它与任何内容都不匹配，那么它只是在进行更新：

UPDATE users SET closed = 'yes' WHERE email = ''

可能会也可能不会更新相关用户。

如果您决定填充...请逃避它;或使用PDO /参数化查询。

Answer 2

根据错误消息，您在includes / header-inc.php文件中调用session_start()。执行Deactivate_myaccount.php时，将打开一个新会话，然后包含标头。由于会话已经打开，header-inc.php无法再次打开它，因此忽略此函数调用。

这仅仅是一个通知，应该修复原因以符合常见的编码样式，但它不应该影响应用程序的功能。我看到其他人已经帮助你解决了这个功能问题。
