解决ecshop订单修改价格后无法再次付款问题

ecshop网店系统客户请求客服在后台修正了订单金额，客户再次付款时就是报错了，提示如下

该疑问的解决办法是找到admin/order.php中的以下代码

/**

* 更新订单对应的 pay_log

* 假如未付出，修正付出金额；不然，生成新的付出log

* @param int $order_id 订单id

*/

function update_pay_log($order_id)

{

$order_id = intval($order_id);

if ($order_id > 0)

{

$sql = "SELECT order_amount FROM " . $GLOBALS['ecs']->table('order_info') .

" WHERE order_id = '$order_id'";

$order_amount = $GLOBALS['db']->getOne($sql);

if (!is_null($order_amount))

{

$sql = "SELECT log_id FROM " . $GLOBALS['ecs']->table('pay_log') .

" WHERE order_id = '$order_id'" .

" AND order_type = '" . PAY_ORDER . "'" .

" AND is_paid = 0";

$log_id = intval($GLOBALS['db']->getOne($sql));

if ($log_id > 0)

{

/* 未付款，更新付出金额 */

$sql = "UPDATE " . $GLOBALS['ecs']->table('pay_log') .

" SET order_amount = '$order_amount' " .

"WHERE log_id = '$log_id' LIMIT 1";

}

else

{

/* 已付款，生成新的pay_log */

$sql = "INSERT INTO " . $GLOBALS['ecs']->table('pay_log') .

" (order_id, order_amount, order_type, is_paid)" .

"VALUES('$order_id', '$order_amount', '" . PAY_ORDER . "', 0)";

}

$GLOBALS['db']->query($sql);

}

}

}

用以下代码将其覆盖

/**

* 更新订单对应的 pay_log

* 假如未付出，修正付出金额；不然，生成新的付出log

* @param int $order_id 订单id

*/

function update_pay_log($order_id)

{

$order_id = intval($order_id);

if ($order_id > 0)

{

$sql = "SELECT order_amount FROM " . $GLOBALS['ecs']->table('order_info') .

" WHERE order_id = '$order_id'";

$order_amount = $GLOBALS['db']->getOne($sql);

if (!is_null($order_amount))

{

$sql = "SELECT log_id, order_amount FROM " . $GLOBALS['ecs']->table('pay_log') .

" WHERE order_id = '$order_id'" .

" AND order_type = '" . PAY_ORDER . "'" .

" AND is_paid = 0";

$log_info =$GLOBALS['db']->GetRow($sql);

if ($log_info && $log_info['order_amount'] == $order_amount)

{

$log_id = intval($log_info['log_id']);

/* 未付款，更新付出金额 */

$sql = "UPDATE " . $GLOBALS['ecs']->table('pay_log') .

" SET order_amount = '$order_amount' " .

"WHERE log_id = '$log_id' LIMIT 1";

}

else

{

/* 已付款，生成新的pay_log */

$sql = "INSERT INTO " . $GLOBALS['ecs']->table('pay_log') .

" (order_id, order_amount, order_type, is_paid)" .

"VALUES('$order_id', '$order_amount', '" . PAY_ORDER . "', 0)";

}

$GLOBALS['db']->query($sql);

}

}

}

找到includes/lib_clips.php的get_paylog_id函数，修正成

/**

* 获得前次未付出的pay_lig_id

*

* @access public

* @param array $surplus_id 余额记录的ID

* @param array $pay_type 付出的类型：预付款/订单付出

*

* @return int

*/

function get_paylog_id($surplus_id, $pay_type = PAY_SURPLUS)

{

$sql = 'SELECT log_id FROM' .$GLOBALS['ecs']->table('pay_log').

" WHERE order_id = '$surplus_id' AND order_type = '$pay_type' AND is_paid = 0 order by log_id
desc ";

return $GLOBALS['db']->getOne($sql);

}

今后客户在后台怎么调整都可以付款了，

一起测了要是是普通的付出宝付款不会呈现上述情况，后台客服怎么修正订单金额都不会报错
