大家都知道ecshop首页的推荐、热卖和新品三个板块的商品都是从所有商品里读取出来的。如果我想“在ecshop首页调用指定分类的推荐、热卖和新品?”该怎么办呢，下面教你一种方法：

　　找到ecshop的includes/lib_goods.php，

　　把SQL语句改一下，与category表关联即可

　　将

$sql =  'SELECT g.goods_id,g.goods_name, g.goods_name_style,g.market_price, g.shop_price AS org_price, g.promote_price, ' .

　　修改为

$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, ' .

　　继续找到

'LEFT JOIN ' . $GLOBALS['ecs']->table('brand') . ' AS b ON b.brand_id = g.brand_id ' .

　　在它下面加一句

'LEFT JOIN ' . $GLOBALS['ecs']->table('category') . ' AS c ON c.cat_id = g.cat_id ' .

　　然后将

if (!empty($cats)){$sql .= " AND (" . $cats . " OR " . get_extension_goods($cats) .")";}

　　改为

if (!empty($cats)){$sql .= " AND (c.parent_id =" . $cats. " OR " . get_extension_goods($cats) .")";}

　　这个是和分类表建立关联，调出商品所在分类的上级分类

　　然后在index.php中增加下面代码

$smarty->assign('chot_goods_35',   get_category_recommend_goods('hot','35'));     //指定分类下的热销商品

　　注意这个35是一级分类的ID，然后在模板中调用即可

<div style="padding-top: 8px;" class="new-tr"><a target="_blank" href="{$goods.url}"><img width="116" height="130" border="0" alt="{$goods.name|escape:HTML}" src="{$goods.thumb}">a><div><a target="_blank" href="{$goods.url}">{$goods.name|escape:html}a><br><span style="color: rgb(102, 102, 102); text-decoration: line-through;">市场价：{$goods.market_price}span><br>特卖价：<span style="color: rgb(255, 0, 0);">{$goods.shop_price}span><br><span class="font-gmm"><a  href="javascript：addToCart({$goods.id})">立即抢购a>span>div><span class="new-line">span>div>

　　同理，新品，推荐都可以调，只要把hot改为new 或者best就可以了
