ECSHOP 商品評論條件修改，修改為購買過該商品多少次，就只能評價多少次。

不需要修改數據庫，原理簡介：先在后臺商店設置->基本->評論條件為只有購買過此商品的會員才能評價

ECSHOP原有機制是只要購買過一次，就可以無限評價。

這里A5源碼小編加入了簡單判斷，判斷會員對此商品是否進行過評價，獲取評價數，再獲取此商品的購物次數。評價數不能大于或等于購物次數。

修改方法如下：

打開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，這文件有兩處一樣的，都要修改！

替換為：

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'] = '您已對此商品進行過評價！您可以繼續購買以便再次評論。';

}

}

}
