php - 使用php将 session 值保存在数据库中

Question

我有这个

session_start();
if ($_SESSION['email']&&$_SESSION['companyID'])
echo $_SESSION['email']."";
else
die("You must be logged in!");

现在我在数据库中保存一些数据，我想通过使用包含这些数据的createUser.php来保存companyID，但它不保存companyID

$userID=0;
$userRole=$_POST ["role"];
$userEmail = $_POST["userEmail"];
$userPassword = $_POST["userPassword"];
$companyID = $_POST[$_SESSION["companyID"]];

//插入到 user_details 表

$sql = "INSERT INTO users (userID, email, password,companyID,roleID) VALUES 
                        ('$userID', '$userEmail', '$userPassword','$companyID','$userRole')";

Answer 1

尝试替换这个:

$companyID = $_POST[$_SESSION["companyID"]];

为此:

$companyID = $_SESSION["companyID"];
