无奈做好事真难，删除图个安心
各位看官请考虑下我免费制作这个效果，并且好心写出教程，无奈网上小人总会以各种方式来说你做得不够，
本人不是来教基础知识的，连基本的模板选择都不会我怎么去教他们做这些功能，反而不教这些基础知识成为了我共享这个功能点的不对的地方。
喜欢这个特效的朋友，可以去下载站点查看:

需要的朋友我只提供程序包，安装方法不再赘述了。
===重新更新帖子里，把以前的删掉了====
安装方法如下：
1. myget_promote_goods()这个函数拷贝到includes/lib_goods.php中
function myget_promote_goods($cats = '')
{
$time =
gmtime();
$order_type
= $GLOBALS['_CFG']['recommend_order'];
$num =
get_library_number("recommend_promotion");
$sql =
'SELECT g.goods_id, g.goods_name,
g.goods_number,g.goods_name_style, g.market_price, g.shop_price AS
org_price, g.promote_price, ' .
"IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS
shop_price, ".
"promote_start_date, promote_end_date, g.goods_brief,
g.goods_thumb, goods_img, b.brand_name, " .
"g.is_best, g.is_new, g.is_hot, g.is_promote, RAND() AS rnd "
.
'FROM ' . $GLOBALS['ecs']->table('goods') . ' AS g '
.
'LEFT JOIN ' . $GLOBALS['ecs']->table('brand') . '
AS b ON b.brand_id = g.brand_id ' .
"LEFT JOIN " .
$GLOBALS['ecs']->table('member_price') . " AS mp
".
"ON mp.goods_id = g.goods_id AND mp.user_rank =
'$_SESSION[user_rank]' ".
'WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND g.is_delete = 0
' .
" AND g.is_promote = 1 AND promote_start_date <=
'$time' AND promote_end_date >= '$time' ";
$sql .=
$order_type == 0 ? ' ORDER BY g.sort_order, g.last_update DESC' : '
ORDER BY rnd';
$sql .= "
LIMIT $num ";

$GLOBALS['db']->getAll($sql);

3.在你需要显示倒计时的地方引用countdown_promote.lbi即可。 如下：
<!-- #BeginLibraryItem
"/library/countdown_promote.lbi"
--><!-- #EndLibraryItem
-->
并且在index.php中对模板变量进行赋值
- $smarty->assign('cats_promote_goods', myget_promote_goods($cat_id)); // 调用栏目限时抢购商品
4. 再次说明下，这个代码例子是基于我的模板上的每个模板的样式不同，需要自行调整。
