How to get a value from session id

Question

I have a page where i need to get a variable from the session to perform an sql query with the variable.

(Please forgive my use of mysql instead of mysqli, i'll work on changing it)

I have tried this $_SESSION["user_name"] = $cnid; its not working.

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. please someone should tell me if am doing something wrong!

Here is the login session:

<?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:

<?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.

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

Change this to:

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

I hope now this solves your problem! :)
