ecshop商品列表页，循环显示当前分类的二级分类以及分类下的商品

1.includes\lib_goods.php,在最末尾添加几个function,

其中的function get_cat_id_goods_list，是按照虚拟销量调用的，具体可参见本人的博文/article/9587562.html

2.category.php，在

后面，添加

如图所示：



ok！完成，顺带说一下，这个循环分类以及显示分类下商品的功能之前博主我在网上找了很久都没有找到，遂，索性自己开发。最关键的是category.php里面的那个foreach循环，有兴趣的同学可以研究看看。特此分享给给位博友。
