如何从会话ID获取值

Question

I have a page where i need to get a variable from the session to perform an sql query with the variable. 我有一个页面，我需要从会话中获取变量以使用该变量执行sql查询。

(Please forgive my use of mysql instead of mysqli, i'll work on changing it) （请原谅我使用mysql而不是mysqli，我将继续进行更改）

I have tried this $_SESSION["user_name"] = $cnid; 我已经试过$_SESSION["user_name"] = $cnid; its not working. 它不起作用。

So i tried to add the variable $cnid and $cnin into the url of the login page and get either of them on the user dashboard page but they don't seem to appear on the url hence the user dashboard page $_GET nothing. 因此，我尝试将变量$cnid和$cnin到登录页面的url中，并在用户显示板页面上获取它们中的任何一个，但它们似乎未显示在url上，因此用户显示板页面$_GET没有显示任何内容。 please someone should tell me if am doing something wrong! 请有人告诉我是否做错了！

Here is the login session: 这是登录会话：

<?php
session_start();
include("server-side/ufunctions.php");
if(count($_POST)>0) {
$sqlses="SELECT * FROM consignments WHERE cn='" . mysql_real_escape_string($_POST['user_name']) . "'";
$resultses= mysql_query($sqlses);
$rwses= mysql_fetch_array($resultses);
$cnid = $rwses[1];    
$cnin = $rwses[0];    
$cnn = mysql_real_escape_string($_POST['user_name']);

    if( $cnn == $cnid ) {
        $_SESSION["user_id"] = 1001;
        $_SESSION["user_name"] = $cnid;
        $_SESSION['loggedin_time'] = time();  
    } else {
        //Login Error Msg
       $msge = "<i class=\"fa fa-exclamation-circle\"></i> Consignment Does Not Exist!";
       header("Location:?msge=$msge");
    }
}

if(isset($_SESSION["user_id"])) {
    if(!isLoginSessionExpired()) {
        //Login Success Msg
       $msg = "<i class=\"fa fa-check\"></i> Welcome $cnid! "; //This where i included the cnid variable to echo as a message for test to know if the link is getting the variables, yet no show!
       header("location:$url/server-side/consignment_detail?cnin=$cnin&msg=$msg"); //So included the cnin as a variable into the url still it didnt show!
    } else {
       header("Location:logout_user.php?session_expired=1");
    }
}

if(isset($_GET["session_expired"])) {
        //Login Error Msg
       $msge = "<i class=\"fa fa-exclamation-circle\"></i> You've Been Checked Out. Please Check Back In!";
       header("Location:?msge=$msge");
}
?>

Here is the User Dashboard: 这是用户仪表板：

<?php 
session_start();
include '_inc/dbconn.php'; 
$sql="SELECT * FROM admin WHERE id='1'";
$result= mysql_query($sql);
$rws= mysql_fetch_array($result);
$url= $rws[7];

include("ufunctions.php");
if(isset($_SESSION["user_id"])) {
    if(isLoginSessionExpired()) {
        header("Location:logout_user?session_expired=1");
    }
}
?>

In your User Dashboard page, Instead of first assigning the session value to a variable just use it directly. 在“用户仪表板”页面中，无需先将会话值分配给变量，只需直接使用它即可。

$_SESSION["user_name"] = $cnid;
$sql1="SELECT * FROM consignments WHERE id='$cnid'";

Change this to: 更改为：

$sql1="SELECT * FROM consignments WHERE id='". $_SESSION["user_name"]."'";

I hope now this solves your problem! 我希望现在可以解决您的问题！ :) :)
