' 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 $where ORDER BY rand() limit 12";    $res = $GLOBALS['db']->query($sql);    $arr = array();//www.zuimoban.com    while ($row = $GLOBALS['db']->fetchRow($res))    {        $arr[$row['goods_id']]['goods_id']     = $row['goods_id'];        $arr[$row['goods_id']]['goods_name']   = $row['goods_name'];        $arr[$row['goods_id']]['short_name']   = $GLOBALS['_CFG']['goods_name_length'] > 0 ?            sub_str($row['goods_name'], $GLOBALS['_CFG']['goods_name_length']) : $row['goods_name'];        $arr[$row['goods_id']]['goods_thumb']  = get_image_path($row['goods_id'], $row['goods_thumb'], true);        $arr[$row['goods_id']]['goods_img']    = get_image_path($row['goods_id'], $row['goods_img']);        $arr[$row['goods_id']]['market_price'] = price_format($row['market_price']);        $arr[$row['goods_id']]['shop_price']   = price_format($row['shop_price']);        $arr[$row['goods_id']]['url']          = build_uri('goods', array('gid'=>$row['goods_id']), $row['goods_name']);        if ($row['promote_price'] > 0)        {            $arr[$row['goods_id']]['promote_price'] = bargain_price($row['promote_price'], $row['promote_start_date'], $row['promote_end_date']);            $arr[$row['goods_id']]['formated_promote_price'] = price_format($arr[$row['goods_id']]['promote_price']);        }        else        {            $arr[$row['goods_id']]['promote_price'] = 0;        }    }    return $arr;} 2，新建ecshop模板文件 category_related_random_goods.lbi代码如下 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"><!-- {if $category_related_random_goods} --> <div class="box">        <h3>Related Products</h3>        <div>        <ul>        <!--{foreach from=$category_related_random_goods item=category_related_random_goods_data}-->                   <li class="li1" style="float:left; margin-bottom:20px;"><a href="{$category_related_random_goods_data.url}"><img src="{$category_related_random_goods_data.goods_thumb}" alt="{$category_related_random_goods_data.goods_name}"/></a></li>        <li class="li2" style="float:left; margin-bottom:20px;"><a href="{$category_related_random_goods_data.url}" title="{$category_related_random_goods_data.goods_name}">{$category_related_random_goods_data.short_name}</a><br />        <!-- {if $category_related_random_goods_data.promote_price neq 0} -->        {$lang.promote_price}<font class="f1">{$category_related_random_goods_data.formated_promote_price}</font>        <!-- {else} -->        {$lang.shop_price}<font class="f1">{$category_related_random_goods_data.shop_price}</font>        <!-- {/if} --></li>        <!--{/foreach}-->        </ul>        </div> </div><div class="blank5"></div><!-- {/if} -->样式可以自己定义把category_related_random_goods.lbi文件复制到 /themes/你使用的模板/library/   文件夹里  3，ecshop找到  /themes/你使用的商城模板/goods.dwt  文件加上 <!-- #BeginLibraryItem "/library/category_related_random_goods.lbi" --><!-- #EndLibraryItem --> 加在 <!-- #BeginLibraryItem "/library/goods_tags.lbi" --><!-- #EndLibraryItem --> 其他ecshop模块是同理的 PS: googs.php 里 ORDER BY rand() limit 12   这个代码 12 就是显示个数的
