ecshop商品分类树显示该分类下的商品数量

1、includes/lib_goods.php下
找到这两个函数改成我这样就行
function get_categories_tree($cat_id = 0)
function get_child_tree($tree_id = 0)

在ecshop模板文件中，可能是category_tree.lbi中，也可能是别的库文件名，总之看模板去改


在{$cat.name}后添加：
({$cat.goods_num})


在{$child.name}后添加：
({$child.goods_num})


在{$childer.name}后添加：
({$childer.goods_num})
