        $goods[$idx][‘brand_name‘] = $row[‘brand_name‘];
        $goods[$idx][‘goods_style_name‘] = add_style($row[‘goods_name‘],$row[‘goods_name_style‘]);
        $goods[$idx][‘short_name‘] = $GLOBALS[‘_CFG‘][‘goods_name_length‘] > 0 ?
            sub_str($row[‘goods_name‘], $GLOBALS[‘_CFG‘][‘goods_name_length‘]) : $row[‘goods_name‘];

    }
    return $goods;
}

?>

第二步:

打开根目录的 index.php 文件，在适当位置添加以下代码：

比如在

$smarty->assign(‘shop_notice‘,     $_CFG[‘shop_notice‘]);       // 商店公告
--------添加

// new新品，hot热销,best为精品,promote特价
$smarty->assign(‘cat_id1_new_goods‘, index_get_cat_id_goods_list(1,10));
$smarty->assign(‘cat_id1_hot_goods‘, index_get_cat_id_goods_list(1,10,‘hot‘));
$smarty->assign(‘cat_id1_hot_goods‘, index_get_cat_id_goods_list(1,10,‘promote‘));
$smarty->assign(‘cat_id1_hot_goods‘, index_get_cat_id_goods_list(1,10,‘best‘));

根据自己的需要添加多条。

其中，1为分类ID，10为调用的数量。

如果不限制商品分类，分类ID可填 0

 

注：如果需要在 分类页调用，则在 category.php 文件中添加。

       如果需要在 商品详情页调用，则在 good.php 文件中添加。
