回答:
需要更改 模板文件

1、修改文件lib_good.php查询语句

/**
* 获得推荐商品
*
* @accesspublic
* @paramstring$type 推荐类型,可以是 best, new, hot
* @returnarray
*/
function get_recommend_goods($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
$sql = 'SELECT g.goods_id, g.goods_sn, g.goods_name, g.goods_name_style, g.market_price, g.shop_price AS org_price, g.promote_price, ' .
"IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, ".
"promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, g.goods_img, RAND() AS rnd " .
'FROM ' . $GLOBALS['ecs']->table('goods') . ' AS g ' .
"LEFT JOIN " . $GLOBALS['ecs']->table('member_price') . " AS mp ".
"ON mp.goods_id = g.goods_id AND mp.user_rank = '$_SESSION[user_rank]' ";
$type_merge = array_merge($type_array['new'], $type_array['best'], $type_array['hot']);
$type_merge = array_unique($type_merge);
$sql .= ' WHERE g.goods_id ' . db_create_in($type_merge);
$sql .= ' ORDER BY goods_id DESC';
$result = $GLOBALS['db']->getAll($sql);
foreach ($result AS $idx => $row)
{
if ($row['promote_price'] > 0)
{
$promote_price = bargain_price($row['promote_price'], $row['promote_start_date'], $row['promote_end_date']);
$goods[$idx]['promote_price'] = $promote_price > 0 ? price_format($promote_price) : '';
}
else
{
$goods[$idx]['promote_price'] = '';
}
$goods[$idx]['id']= $row['goods_id'];
$goods[$idx]['name']= $row['goods_name'];
$goods[$idx]['goods_sn']= $row['goods_sn'];
$goods[$idx]['brief']= $row['goods_brief'];
$goods[$idx]['brand_name']= isset($goods_data['brand'][$row['goods_id']]) ? $goods_data['brand'][$row['goods_id']] : '';
$goods[$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']= get_image_path($row['goods_id'], $row['goods_thumb'], true);
$goods[$idx]['goods_img'] = get_image_path($row['goods_id'], $row['goods_img']);
$goods[$idx]['url'] = build_uri('goods', array('gid' => $row['goods_id']), $row['goods_name']);
if (in_array($row['goods_id'], $type_array['best']))
{
$type_goods['best'][] = $goods[$idx];
}
if (in_array($row['goods_id'], $type_array['new']))
{
$type_goods['new'][] = $goods[$idx];
}
if (in_array($row['goods_id'], $type_array['hot']))
{
$type_goods['hot'][] = $goods[$idx];
}
}
}
return $type_goods[$type];
}

2、在模板中直接调用数据

{$goods.goods_sn}

为何我无效,我也是按上述代码进行更改的,不过我现是2.70版本了。不知哪出错,大家帮我看看
