Note this DEMO passes a variable (and it's value) via a POST ternary operation. In other words, the name of the variable and it's value is being passed through POST form.
This could be used to give users an option to flip through choices. The id in this example refers to a category of furniture for sale.
Category:
beds
ID = 0
<?php
// get header file
include('includes/header.php');
// set error reporting to all
error_reporting(E_ALL);
// get the id from a POST operation via POST ternary operator
$id = isset($_POST['id']) ? $_POST['id'] : 0;
// create items array for shopping demonstration
$items = array("beds","bookshelves","chairs","coffee tables","desks","dining chairs",
"dining tables","dressers","end tables","kids furniture","recliners","sofas");
