ecshop商品详情页添加调用同类随机商品

通过以下教程可以实现，在ECSHOP商品详情页中调用显示同类的随机商品
1，根目录下找到goods.php文件
查找代码：
$smarty->assign('properties',
$properties['pro']);
// 商品属
在上面一行添加以下代码：
$smarty->assign('category_related_random_goods',
category_related_random_goods($goods['cat_id']));
// 同分类随机商品
接着还在goods.php文件的低部也就是 ?>前添加以下代码：
/*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 到 /themes/你使用的模板/library/   文件夹里
3，找到  /themes/你使用的模板/goods.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 ORDER BY rand() limit 12   这个代码 12 就是显示个数的
