1，根目录下找到googs.php文件
找到代码 $smarty->assign(‘properties’, $properties[‘pro’]); // 商品属性
在上面加代码 $smarty->assign(‘category_related_random_goods’, category_related_random_goods($goods[‘cat_id’])); // 同分类随机商品
再在最底部添加上 随机同类商品的函数， 以下代码
/*同分类下随机推荐商品*/function category_related_random_goods($category_id){ $where = "g.is_on_sale = 1 AND g.is_alone_sale = 1 AND ". "g.is_delete = 0 AND g.cat_id=$category_id "; $sql = 'SELECT g.goods_id, g.goods_name, g.goods_name_style, g.market_price, g.is_new, g.is_best, g.is_hot, g.shop_price AS org_price, ' . "IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, g.promote_price, g.goods_type, " . '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 $where ORDER BY rand() limit 12"; $res = $GLOBALS['db']->query($sql); $arr = array(); while ($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，找到 /themes/你使用的模板/googs.dwt文件
在适当的位置加上
<!– #BeginLibraryItem”/library/category_related_random_goods.lbi”–><!– #EndLibraryItem–>一般加在 <!– #BeginLibraryItem “/library/goods_tags.lbi”–><!– #EndLibraryItem–>
下面或者上面，和其他模块是同理的
PS: googs.php里 ORDERBYrand()limit12 这个代码12就是显示个数的
