ECSHOP 商品评论条件修改――购买过该商品且只能评价一次（购买多少次能评价多少次）

ECSHOP 商品评论条件修改，修改为购买过该商品多少次，就只能评价多少次。

不需要修改数据库，原理简介：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

ECSHOP原有机制是只要购买过一次，就可以无限评价。

这里A5源码小编加入了简单判断，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。

修改方法如下：

打开comment.php

找到：

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'];

}

}

注意，这文件有两处一样的，都要修改！

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 . "') ".

" LIMIT 1";

$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 . "'".

" LIMIT 1";

$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。';

}

}

}
