This was covered in a previous video. The controller code is located in the shirts.php page. Specifically, these few lines:

$start = (($current_page * $products_per_page) - $products_per_page) + 1;
$end = $current_page * $products_per_page;

You need to understand how how we get the current_page and products_per_page and these are located in the same file:

// this is how we get the $current_page variable
if (empty($_GET['pg'])) {
    $current_page = 1;
} else {
    $current_page = $_GET['pg'];

// this is how we get the $products_per_page variable
$products_per_page = 8;
