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

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

一般加在
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
