ECSHOP 购买条件优化-购买过几件该商品，就只能评价几次
ECSHOP原有机制是只要购买过一次，就可以无限评价。我们则需要判断会员对此商品是否进行过评价，获取评价数，再获取此商品的购物次数，评价数不能大于或等于购物次数。
第一步：先在后台商店设置->基本->评论条件为只有购买过此商品的会员才能评价第二步：
打开comment.php找到：如下代码(PS您会找到两处，都要替换)case COMMENT_BOUGHT : if ($_SESSION[‘user_id’] > 0) { $sql = "SELECT o.order_id". " FROM " . $ecs->table(‘order_info’). " AS o, ". $ecs->table(‘order_goods’) . " AS og ". " WHERE o.order_id = og.order_id". " AND o.user_id = ‘" . $_SESSION[‘user_id’] . "’". " AND og.goods_id = ‘" . $cmt->id . "’". " AND o.order_status = ‘" . OS_CONFIRMED . "’ ". " AND (o.pay_status = ‘" . PS_PAYED . "’ OR o.pay_status = ‘" . PS_PAYING . "’) ". " AND (o.shipping_status = ‘" . SS_SHIPPED . "’ OR o.shipping_status = ‘" . SS_RECEIVED . "’) ". " LIMIT 1"; $tmp = $db->getOne($sql); if (emptyempty($tmp)) { $result[‘error’] = 1; $result[‘message’] = $_LANG[‘comment_brought’]; } }
替换为：
case COMMENT_BOUGHT : if ($_SESSION[‘user_id’] > 0) { $sql = "SELECT COUNT(o.order_id)". " FROM " . $ecs->table(‘order_info’). " AS o, ". $ecs->table(‘order_goods’) . " AS og ". " WHERE o.order_id = og.order_id". " AND o.user_id = ‘" . $_SESSION[‘user_id’] . "’". " AND og.goods_id = ‘" . $cmt->id . "’". " AND (o.order_status = ‘" . OS_CONFIRMED . "’ or o.order_status = ‘" . OS_SPLITED . "’) ". " AND (o.pay_status = ‘" . PS_PAYED . "’ OR o.pay_status = ‘" . PS_PAYING . "’) ". " AND (o.shipping_status = ‘" . SS_SHIPPED . "’ OR o.shipping_status = ‘" . SS_RECEIVED . "’) "; $bought_count = $db->getOne($sql); if (!$bought_count) { $result[‘error’] = 1; $result[‘message’] = $_LANG[‘comment_brought’]; }else{ $sql = "SELECT COUNT(comment_id) FROM " . $ecs->table(‘comment’) . " WHERE user_id = ‘" . $_SESSION[‘user_id’] . "’". " AND id_value= ‘" . $cmt->id . "’"; $comment_count = $db->getOne($sql); if($comment_count >= $bought_count){ $result[‘error’] = 1; $result[‘message’] = ‘您已对此商品进行过评价！您可以继续购买以便再次评论。’; } } }
，回避现实的人，未来将更不理想。
