我正在使用PS 1.6.1.16，我想知道，如果产品类型是 "虚拟"（在BO中设置），是否有办法在product.tpl上显示 "额外 "或 "不同 "的内容。
另外，有没有办法为所有这些 "虚拟 "产品创建一个分类页？
先谢谢你了。
在tpl条件是 。
{if $product->is_virtual} IS VIRTUAL PRODUCT {else} NO VIRTUAL PRODUCT {/if}
要有一个专门的页面是不同的，这里是一个例子的产品覆盖，把在 ROOT/override/controllers/front/ProductController.php 允许你为虚拟产品加载一个新的TPL。因此，有必要在主题中添加一个product_virtual.tpl文件。
<?php

// Assign to the template the id of the virtual product. "0" if the product is not downloadable.
$this->context->smarty->assign('virtual', ProductDownload::getIdFromIdProduct((int)$this->product->id));
