Question

所以我试图将一些会话变量输入到数据库中，并且我成功地插入了所有行，除了$ _SESSION ['organisationId']。一些上下文：用户登陆下面的snippit中给出的URL，我得到organisationId，然后希望在创建帐户时为该用户分配organisationId - 作为一种“邀请系统”进行排序。

//这是我正在使用的网址：http://thisapp.com/login.php?competitionId=51da7ed4d686a&organisationId=51d81cab92709

   <?php
      session_start();
      ob_start();
      ini_set('display_errors',1);
      ini_set('display_startup_errors',1);
      error_reporting(-1);

       include('db.php');

    $_SESSION['competitionId'] = $_GET['competitionId'];
    $_SESSION['organisationId'] = $_GET['organisationId'];

    <h4>Create your Account</h4>

    <form action="login.php" method="post" name="acceptinvite">
        name: <input type="text" name="createname"><br>
        email: <input type="text" name="createemail"><br>
        password: <input type="password" name="createpassword"><br>
        <input type="submit" value="Create Account">
    </form>

    <?php

    if (isset($_POST["createname"]) && !empty($_POST["createname"])) {

        //define variables
        $name = mysql_real_escape_string($_POST['createname']);
        $email = mysql_real_escape_string($_POST['createemail']);
        $password = mysql_real_escape_string($_POST['createpassword']);
        $teamLeader = 0;
        $organisationId = mysql_real_escape_string($_SESSION['organisationId']);
        $orgName = mysql_real_escape_string($_SESSION['orgName']);

        //finish registering the user
        $acceptInviteTeam = ("INSERT INTO `users` (`organisationId`, `name`, `email`, `password`, `isTeamLeader`) VALUES ('$organisationId', '$name', '$email', '$password', '$teamLeader')");
        $result = mysql_query($acceptInviteTeam)  or die (mysql_error());
    }

    else {
        echo "Fill out the form and use the correct credentials";
    }


    ?>

这就是问题所在。当您输入链接http://thisapp.com/login.php?competitionId=51da7ed4d686a&organisationId=51d81cab92709时，您有organisationId并将其保存在会话中。但是表单的目标只是login.php。提交表单时，url中没有organisationId，因此会话变量被null覆盖。这是修复：

$_SESSION['competitionId'] = isset($_GET['competitionId']) ? $_GET['competitionId'] : $_SESSION['competitionId'];
$_SESSION['organisationId'] = isset($_GET['organisationId']) ? $_GET['organisationId'] : $_SESSION['organisationId'];

或者，您可以使用if语句。
