我想在这个方法里多查询个分类名称。。

我改成这样了。。但是分类名称没出来是不是少改什么东西了？

回答：
有谁能帮帮我？？？

额。。。没人？？？？我发错地方了？？



怎么说呢，只能说楼主是一个很不细心的人（说话直接），
注意你改过的
$sql ='SELECT g.goods_id, g.cat_name, g.goods_name, g.goods_name_style,

应该是ca.cat_name 而不是 g.cat_name

ecs_goods 这数据表里是没有cat_name 这个字段的，

那个。。我用ca.cat_name 这个字段名也读不出来。。。

老大还在么？？？？

function get_category_recommend_goods($type = '', $cats = '', $brand = 0, $min =0,$max = 0, $ext='')

$idx++;
}
return $goods;
}

满意把...

不行啊。。老大。还是没出来。

我发现了。。。 是{$goods.cat_name}读不出来。。。怎么办？

有人帮帮我么？？？？

查sql 里面是否有 cat_name
