1、修改文件lib_good.php查询语句
/*** 获得推荐商品** @access public* @param string $type 推荐类型，可以是 best, new, hot* @return array*/function get_recommend_goods($type = ”, $cats = ”){ if (!in_array($type, array(‘best’, ‘new’, ‘hot’))) { return array(); } //取不同推荐对应的商品 static $type_goods = array(); if (empty($type_goods[$type])) { //初始化数据 $type_goods[‘best’] = array(); $type_goods[‘new’] = array(); $type_goods[‘hot’] = array(); $data = read_static_cache(‘recommend_goods’); if ($data === false) { $sql = ‘SELECT g.goods_id, g.goods_sn, g.is_best, g.is_new, g.is_hot, g.is_promote, b.brand_name ‘ . ‘ FROM ‘ . $GLOBALS[‘ecs’]->table(‘goods’) . ‘ AS g ‘ . ‘ LEFT JOIN ‘ . $GLOBALS[‘ecs’]->table(‘brand’) . ‘ AS b ON b.brand_id = g.brand_id ‘ . ‘ WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND g.is_delete = 0 AND (g.is_best = 1 OR g.is_new =1 OR g.is_hot = 1)’; $goods_res = $GLOBALS[‘db’]->getAll($sql); //定义推荐,最新，，热门，促销商品 $goods_data[‘best’] = array(); $goods_data[‘new’] = array(); $goods_data[‘hot’] = array(); $goods_data[‘brand’] = array(); if (!empty($goods_res)) { foreach($goods_res as $data) { if ($data[‘is_best’] == 1) { $goods_data[‘best’][] = $data[‘goods_id’]; } if ($data[‘is_new’] == 1) { $goods_data[‘new’][] = $data[‘goods_id’]; } if ($data[‘is_hot’] == 1) { $goods_data[‘hot’][] = $data[‘goods_id’]; } if ($data[‘brand_name’] != ”) { $goods_data[‘brand’][$data[‘goods_id’]] = $data[‘brand_name’]; } } } write_static_cache(‘recommend_goods’, $goods_data); } else { $goods_data = $data; } $time = gmtime(); $order_type = $GLOBALS[‘_CFG’][‘recommend_order’]; //按推荐数量及排序取每一项推荐显示的商品 order_type可以根据后台设定进行各种条件显示 static $type_array = array(); $type2lib = array(‘best’=>’recommend_best’, ‘new’=>’recommend_new’, ‘hot’=>’recommend_hot’); if (empty($type_array)) { foreach($type2lib as $key => $data) { if (!empty($goods_data[$key])) { $num = get_library_number($data); $data_count = count($goods_data[$key]); $num = $data_count > $num ? $num : $data_count; if ($order_type == 0) { rsort($goods_data[$key]); $type_array[$key] = array_slice($goods_data[$key], 0, $num); } else { $rand_key = array_rand($goods_data[$key], $num); foreach($rand_key as $key_data) { $type_array[$key][] = $goods_data[$key][$key_data]; } } } else { $type_array[$key] = array(); } } } //取出所有符合条件的商品数据，并将结果存入对应的推荐类型数组中 $sql = ‘SELECT g.goods_id, g.goods_sn, g.goods_name, g.goods_name_style, g.market_price, g.shop_price AS org_price, g.promote_price, ‘ .

2、在模板中直接调用数据
{$goods.goods_sn}
把你的脸迎向阳光，那就不会有阴影
