Answer 1

If you are getting an array from your HTML form then you need to loop on this array and insert each row separately into DB. To do this you need to use prepared statement and a loop.

if (isset($_GET['submit'])) {
    $client_id = $value->ID; // Wherever this value comes from...

    // Insert new sales order
    $stmt = $mysql->prepare('INSERT INTO salesorder (client_id) VALUES (?)');
    $stmt->bind_param('s', $client_id);
    $stmt->execute();
    $stmt->store_result();

    $order_id = $mysql->insert_id;

    // prepare the SQL statement
    $orderline_stmt = $mysql->prepare('INSERT INTO orderline (order_id, food_id, qty) VALUES (?,?,?)');

    // loop on each element from HTML form 
    // i.e. 
    foreach ($_GET['foodid'] as $key => $food_id) {
        $qty = $_GET['qty']; // should this be an array too?
        // $qty = $_GET['qty'][$key]; <-- if it's also an array

        $orderline_stmt->bind_param('sss', $order_id, $food_id, $qty);
        $orderline_stmt->execute();
    }
}
