使用ecshop开发过程中要求在首页循环调用新品、精品、热销的商品列表，同时调用该商品的所属于的那个分类，点击这个分类，可以链接到该分类。
所用ecshop版本为v2.7.2 RELEASE 20100604，修改方法如下：
在文件includes/lib_goods.php约289行修改成如下：
//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
$sql='SELECT g.goods_id, g.goods_name, g.goods_name_style, g.market_price, g.shop_price AS org_price, g.promote_price, '.
"IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, ".
"promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, g.goods_img, RAND() AS rnd, ". // 分隔字段，连接语句
"c.cat_id, c.cat_name ".
// 第1处，查询分类ID和名称
'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]' ".
"LEFT JOIN" . $GLOBALS['ecs']->table('category') . " AS c ".
// 第2处，连接分类数据表
"ON g.cat_id = c.cat_id ";
// 第3处，通过ID找到分类
$sql='SELECT g.goods_id, g.goods_name, g.goods_name_style, g.market_price, g.shop_price AS org_price, g.promote_price, '.
"IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, ".
"promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, g.goods_img, RAND() AS rnd, ". // 分隔字段，连接语句
"c.cat_id, c.cat_name ".
// 第1处，查询分类ID和名称
'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]' ".
"LEFT JOIN" . $GLOBALS['ecs']->table('category') . " AS c ".
// 第2处，连接分类数据表
"ON g.cat_id = c.cat_id ";
// 第3处，通过ID找到分类
在该php文件约332行加入如下几句：
$goods[$idx]['url']=build_uri('goods', array('gid' => $row['goods_id']), $row['goods_name']);
$goods[$idx]['cat_name']=$row['cat_name'];
// 第4处，处理分类名称
$goods[$idx]['cat_url']=build_uri('category', array('cid' => $row['cat_id']), $row['cat_name']);
// 第5处，处理分类链接地址
$goods[$idx]['cat_name']=$row['cat_name'];
// 第4处，处理分类名称
$goods[$idx]['cat_url']=build_uri('category', array('cid' => $row['cat_id']), $row['cat_name']);
// 第5处，处理分类链接地址
修改完以上五处，假如我们想调用新品，在dwt模板themes/default/index.dwt中调用时就可以这样：
<!--{foreach from=$new_goods item=goods}-->
<div>
<p><a href="{$goods.url}"><img src="{$goods.thumb}" alt="{$goods.name|escape:html}"></a></p>
<p><a href="{$goods.cat_url}">{$goods.cat_name}</a></p>
<p><a href="{$goods.url}" title="{$goods.name|escape:html}">{$goods.short_style_name}</a></p>
<p>价格：<span class="red">{$goods.shop_price}</span></p>
</div>
<!--{/foreach}-->
<div>
<p><a href="{$goods.url}"><img src="{$goods.thumb}" alt="{$goods.name|escape:html}"></a></p>
<p><a href="{$goods.cat_url}">{$goods.cat_name}</a></p>
<p><a href="{$goods.url}" title="{$goods.name|escape:html}">{$goods.short_style_name}</a></p>
<p>价格：<span class="red">{$goods.shop_price}</span></p>
</div>
<!--{/foreach}-->
至此，完成收工！
