SELECT query for selecting logged in users rows only - PHP/MySQL

I have a members only website in which the logged in users fill in an entry form which goes to a MySQL table called 'ltd_sales_list' with the following columns:

ltd_item_id | ltd_user_id | ltd_invoice_no | ltd_entry_amount | ltd_entry_date

For each new entry they input, a new id/primary key is generated ('ltd_item_id') for each row, while their SESSION log in id is recorded in 'ltd_user_id' while the 'ltd_entry_date' is a timestamp. The entry form page works fine but viewing the entry data is where I am having the issue.

I have put together the code below called view-list.php but this calls up every user's entry list. What I am trying to do is show the logged in user's entry list only.

I think the answer lies within the queries somewhere and have tried some WHERE statements with ltd_user_id = $_SESSION['ltd_user_id'] and similar but for no success.

If anyone could help or could point me to some links that would be greatly appreciated!

<?php 

require_once ('./includes/config.inc.php');

$page_title = 'Page Title';
include ('./includes/header.html');

if (!isset($_SESSION['ltd_user_id'])) {

   $url = 'http://' . $_SERVER['HTTP_HOST']
    . dirname($_SERVER['PHP_SELF']);

   if ((substr($url, -1) == '/') OR (substr($url, -1) == '\\') ) {
        $url = substr ($url, 0, -1); 
   }

   $url .= '/login.php'; 
ob_end_clean(); 
header("Location: $url"); 
exit(); 
}

Could it be as simple as escaping everything, exiting from the quotes when doing variables? It looks to me like it should work. Can you vardump the $_SESSION['ltd_user_id'] somewhere to make sure it is behaving as expected?

$query = "SELECT `ltd_invoice_no`, `ltd_entry_amount`,  
DATE_FORMAT(`ltd_entry_date`, '%M %d, %Y') AS `dr`, `ltd_user_id` FROM `ltd_sales_list` WHERE `ltd_user_id` = '".$_SESSION['ltd_user_id']."' ORDER BY
".$order_by." LIMIT ".$start.", ".$display;
