Question

我正在尝试在用户登录时启动3个会话但是唯一正在开始的会话是$email=$_POST['email']
这是我的代码。

if(isset($_POST['log'])) // code to be executed when login button is clicked
{
    $email=$_POST['email'];
    $password=$_POST['Password'];

    $query= "SELECT * FROM student 
    WHERE EmailAddress = '$email' AND Password = '$password'";

    $query_run = mysqli_query($con,$query);
    if(mysqli_num_rows($query_run)>0)
    {
        //checks the database where this user exist or not

        $_SESSION['email']=$email;
        $_SESSION['StudentID']=$student;
        $_SESSION['OfferingID']=$Offering;


        header('location: profile.php'); //
    }
    else
    {
        echo '<script type = "text/javascript"> alert("Invalid Credentials or Not yet registered!") </script>';
    }
}

Answer 1

假设studentID和产品来自数据库记录，您需要获取数据并从提取的记录中提取这些字段。

像...一样的东西。

    $student = mysqli_fetch_assoc($query_run);
    $_SESSION['email']=$email;
    $_SESSION['StudentID']=$student['studentID'];
    $_SESSION['OfferingID']=$student['OfferingID'];

Answer 2

首先在您的代码中获取$ student和$ offer条件

if(isset($_POST['log'])) // code to be executed when login button is clicked
{
    $email=$_POST['email'];
    $password=$_POST['Password'];

    $query= "SELECT * FROM student 
    WHERE EmailAddress = '$email' AND Password = '$password'";

    $query_run = mysqli_query($con,$query);
    if(mysqli_num_rows($query_run)>0)
    {
        //fetch array and get values for studentid and offeringid
        $student = mysqli_fetch_assoc($query_run);
    $_SESSION['email']=$email;
    $_SESSION['StudentID']=$student['studentID'];
    $_SESSION['OfferingID']=$student['OfferingID'];


        header('location: profile.php'); //
    }
    else
    {
        echo '<script type = "text/javascript"> alert("Invalid Credentials or Not yet registered!") </script>';
    }
}

在这里我再次设置检查

Answer 3

def send_compute_to_client():
    time.sleep(20)
    print("Sleep over")
    for _, client_sock in client_name_to_sock_mapping.iteritems():
        print("client = {}".format(client_sock))
        client_sock.sendall("COMPUTE 1,2,3")
        print("send completed = {}".format(client_sock))
        data = client_sock.recv(1024)
        print("Computed results from client {}".format(data))

我已经编辑了我的答案..
只需检查正确的字段和表名称。
