笔者在做ecshop二次开发时曾开发过商品内容页左侧“浏览过此商品的人还购买了”的功能（发现京东、凡客均有此功能），在此和大家分享一下：
一、数据库设计建一张表，ecs_goods_visiter,用于将记录浏览过某商品的用户。结构如下：
五个字段名分别为：表自增ID、用户ID、商品ID、浏览时间、浏览次数。同一用户浏览同一商品时更改浏览时间即可。
二、修改goods.php文件
在文件末尾添加函数如：
function get_view_and_bought($goods_id) { $sql = 'SELECT d.goods_id, d.goods_name, d.goods_thumb, d.goods_img, d.shop_price, d.promote_price, d.promote_start_date, d.promote_end_date ' . 'FROM ' . $GLOBALS['ecs']->table('goods_visitor') . ' AS v ' . 'LEFT JOIN ' . $GLOBALS['ecs']->table('order_info') . ' AS b ON b.user_id = v.user_id ' . 'LEFT JOIN ' . $GLOBALS['ecs']->table('order_goods') . ' AS c ON c.order_id = b.order_id ' . 'LEFT JOIN ' . $GLOBALS['ecs']->table('goods') . ' AS d ON d.goods_id = c.goods_id ' . "WHERE v.goods_id = '$goods_id' AND (b.shipping_status = 1 OR b.shipping_status = 2 OR b.shipping_status = 5) AND d.is_on_sale = 1 AND d.is_alone_sale = 1 AND d.is_delete = 0 " . 'ORDER BY b.order_id DESC ' . 'LIMIT ' . $GLOBALS['_CFG']['bought_goods']; $res = $GLOBALS['db']->query($sql); $key = 0; $arr = array(); while ($row = $GLOBALS['db']->fetchRow($res)){ $arr[$key]['goods_id'] = $row['goods_id']; $arr[$key]['goods_name'] = $row['goods_name']; $arr[$key]['short_name'] = $GLOBALS['_CFG']['goods_name_length'] > 0 ? sub_str($row['goods_name'], $GLOBALS['_CFG']['goods_name_length']) : $row['goods_name']; $arr[$key]['goods_thumb'] = get_image_path($row['goods_id'], $row['goods_thumb'], true); $arr[$key]['goods_img'] = get_image_path($row['goods_id'], $row['goods_img']); $arr[$key]['shop_price'] = price_format($row['shop_price']); $arr[$key]['url'] = build_uri('goods', array('gid'=>$row['goods_id']), $row['goods_name']); if ($row['promote_price'] > 0) { $arr[$key]['promote_price'] = bargain_price($row['promote_price'], $row['promote_start_date'], $row['promote_end_date']); $arr[$key]['formated_promote_price'] = price_format($arr[$key]['promote_price']); }else { $arr[$key]['promote_price'] = 0; } $key++; } return $arr; }
最后找到：$smarty->assign('bought_goods', get_also_bought($goods_id)); // 购买了该商品的用户还购买了哪些商品
并在该行下面添加：
$smarty->assign('view_and_bought', get_view_and_bought($goods_id)); // 浏览过该商品的用户还购买了哪些商品
三、修改模板文件goods.dwt
在library文件夹中新建view_and_shopping.lbi文件，代码如下：
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <!-- {if $view_and_bought} --> <div class="box"> <div class="box_1" id="left_box_re"> <h3><span class="text">{$lang.view_and_shopping}</span></h3> <div class="boxCenterList clearfix ie6" style="margin:0;padding-left:7px;"> <!--{foreach from=$view_and_bought item=bought_goods_data}--> <ul class="clearfix"> <li class="goodsimg"><a href="{$bought_goods_data.url}"><img src="{$bought_goods_data.goods_thumb}" alt="{$bought_goods_data.goods_name}" class="B_blue" /></a></li> <li><a href="{$bought_goods_data.url}" title="{$bought_goods_data.goods_name}">{$bought_goods_data.short_name}</a> <!-- {if $bought_goods_data.promote_price neq 0} --> <font class="shop_s">{$bought_goods_data.formated_promote_price}</font> <!-- {else} --> <font class="shop_s">{$bought_goods_data.shop_price}</font> <!-- {/if} --> </li> </ul> <!-- {/foreach} --> </div> </div> </div> <div class="blank5"></div> <!-- {/if} --> 最后在goods.dwt找到：<!-- #BeginLibraryItem "/library/history.lbi" --><!-- #EndLibraryItem -->
在该行下面添加：<!-- #BeginLibraryItem "/library/view_and_shopping.lbi" --><!-- #EndLibraryItem --> 最后效果图如下：
