ECSHOP首页商品随机排序的三种方法
首页商品随机排序的三种方法都是修改inlcudes/lib_goods.php这个文件
1 精品推荐 新品上架 热卖商品 促销商品 团购商品 拍卖商品 6类随机排序的调整方法
将$order_type = 0;改为$order_type = 1
2 修改“分类下的商品”排列顺序为随机
将assign_cat_goods这个函数中的sql
$sql = 'SELECT g.goods_id, g.goods_name, g.market_price, g.shop_price AS org_price, ' .
"IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, ".
'g.promote_price, promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, g.goods_img ' .
"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]' ".
'WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND '.
'g.is_delete = 0 AND (' . $children . 'OR ' . get_extension_goods($children) . ') ' .
'ORDER BY g.sort_order, g.goods_id DESC';
改为
$order_type = 1;
$sql = 'SELECT g.goods_id, g.goods_name, g.market_price, g.shop_price AS org_price, ' .
"IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, ".
'g.promote_price, promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, g.goods_img ' .
"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]' ".
'WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND '.
'g.is_delete = 0 AND (' . $children . 'OR ' . get_extension_goods($children) . ') ' ;
$sql .= $order_type == 0 ? ' ORDER BY g.sort_order, g.goods_id DESC' : ' ORDER BY RAND()';
其实就是在第一行加上一句“$order_type = 1;”，在最后一行的前面加上“$sql .= $order_type == 0 ? ”，后面加上“ : ' ORDER BY RAND()'”，别忘了是在最后的“;”之前
3 修改“品牌的商品”排列顺序为随机
在assign_brand_goods这个函数的前面加入一句“$order_type = 1;”，将该函数下方第五行的“$sql .= ' ORDER BY g.sort_order, g.goods_id DESC';”改为“$sql .= $order_type == 0 ? ' ORDER BY g.sort_order, g.goods_id DESC' : ' ORDER BY RAND()';”即可
就是将
function assign_brand_goods($brand_id, $num = 0, $cat_id = 0)
{
$sql = 'SELECT g.goods_id, g.goods_name, g.market_price, g.shop_price AS org_price, ' .
"IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, ".
'g.promote_price, g.promote_start_date, g.promote_end_date, g.goods_brief, g.goods_thumb, g.goods_img ' .
'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]' ".
"WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND g.is_delete = 0 AND g.brand_id = '$brand_id'";
if ($cat_id > 0)
{
$sql .= get_children($cat_id);
}
$sql .= ' ORDER BY g.sort_order, g.goods_id DESC';
改为
function assign_brand_goods($brand_id, $num = 0, $cat_id = 0)
{
$order_type = 1;
$sql = 'SELECT g.goods_id, g.goods_name, g.market_price, g.shop_price AS org_price, ' .
"IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, ".
'g.promote_price, g.promote_start_date, g.promote_end_date, g.goods_brief, g.goods_thumb, g.goods_img ' .
'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]' ".
"WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND g.is_delete = 0 AND g.brand_id = '$brand_id'";
if ($cat_id > 0)
{
$sql .= get_children($cat_id);
}
$sql .= $order_type == 0 ? ' ORDER BY g.sort_order, g.goods_id DESC' : ' ORDER BY RAND()';
上面就是我的做法，实际应用也达到了预期的效果，帖出来也大家共享，有不同方法还望与大家共同讨论。
谢谢！
[color=red]---------这篇文章是百度找的，不是本人原创[/color] 感觉改得好多，现在不敢随便改代码
实际运营的，总怕问题出现！ 好东西..先收藏了 为何我试了而没有效果呢？ 我现在都是用默认的模板了，没什么大的必要不怎么想动多少 :D 这个功能不错，会有一天需要的。 不能用啊，~
