ecshop3 调用指定分类下推荐/热卖/新品商品，可指定调用数量

第一步:
--------------------------------------------------------------------------------------
/**
 * 取指定分类ID及类型的商品信息
 * @access public
 * @param string $cat_id 分类ID
 * @param string $num 显示商品数量
 * @param string $cat_type 显示商品类型 new新品，hot热销,best为精品,promote特价
 * @param auther 邓士鹏(自定义函数)
 * @return array
 */
function index_get_cat_id_goods_list($cat_id = '', $num = '',$cat_type='')
{
    $sql = 'Select g.goods_id, g.cat_id,c.parent_id, g.goods_name, g.goods_name_style, g.market_price, g.shop_price AS org_price, g.promote_price, ' .
        "IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, ".
        "promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, goods_img, " .
        "g.is_best, g.is_new, g.is_hot, g.is_promote " .
        'FROM ' . $GLOBALS['ecs']->table('goods') . ' AS g ' .

    if($cat_type!=''){
        $sql .=" and is_".$cat_type."=1";
    }else{
        $sql .=" and is_best=0 and is_new=0 and is_hot=0 and is_promote=0";
    }
    $sql .= " order by g.goods_id desc LIMIT $num";

    foreach ($res AS $idx => $row)
    {
        $goods[$idx]['id'] = $row['article_id'];
        $goods[$idx]['id'] = $row['goods_id'];
        $goods[$idx]['name'] = $row['goods_name'];
        $goods[$idx]['brief'] = $row['goods_brief'];
        $goods[$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'];
        $goods[$idx]['short_style_name'] = add_style($goods[$idx]['short_name'],$row['goods_name_style']);
        $goods[$idx]['market_price'] = price_format($row['market_price']);
        $goods[$idx]['shop_price'] = price_format($row['shop_price']);
        $goods[$idx]['thumb'] = empty($row['goods_thumb']) ? $GLOBALS['_CFG']['no_picture'] : $row['goods_thumb'];
        $goods[$idx]['goods_img'] = empty($row['goods_img']) ? $GLOBALS['_CFG']['no_picture'] : $row['goods_img'];
        $goods[$idx]['url'] = build_uri('goods', array('gid' => $row['goods_id']), $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。
