<span>{{ product.name }}{% if not product.stock %} <span class="text-danger">***</span><?php echo $product['quantity'] ?> шт.<?php } ?> {% endif %}</span>

'stock'     => $product['stock'] ? true : !(!$this->config->get('config_stock_checkout') || $this->config->get('config_stock_warning')),

{{ product.name }}{% if not product.stock %} *** {{ product.quantity }} pcs.
so displays the amount selected
