导读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

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，就可以评价。
这里加入了简单判断，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。
修改如下：
打开comment.php
找到：(注意，这文件有两处一样的，都要修改！)

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。';
}
}
}
