我有一个网站，登录的用户可以累积积分，以后可以通过购物车购买。下面的页面是一个管理员PHP功能，管理员可以在其中为单个用户（一次一个用户）提供点数。
此脚本涉及三个表：
用户包含用户详细信息
tally_point：存储所有积分交易，包括传入和订购
reward_points：存储用户拥有的总点数
该脚本通过下拉菜单检索用户的详细信息，并将这些点添加到计数点表中，但是......
<?php # add-points-ind.php
// This is the main page for the site.
// Include the configuration file for error management and such.
require_once ('./includes/config.inc.php');

$page_title = 'Add Points to User';
include ('includes/header_admin_user.html');
// If no dealer_code variable exists, redirect the user.
if (!isset($_SESSION['admin_int_id'])) {
// Start defining the URL.
$url = 'http://' . $_SERVER['HTTP_HOST']
. dirname($_SERVER['PHP_SELF']);
// Check for a trailing slash.
if ((substr($url, -1) == '/') OR (substr($url, -1) == '\\') ) {
$url = substr ($url, 0, -1); // Chop off the slash.
}

$url .= '/login.php';
ob_end_clean(); // Delete the buffer.

...我在 reward_points 表中将新点添加到积分总计字段（reward_user_points）时遇到问题，我在下面有一些代码，但我不确定我应该放在哪里如果有人有任何建议请告诉我。
<?php
$query = "SELECT reward_user_points FROM reward_points WHERE users_id = $a";
$result = mysql_query($query);
$row = mysql_fetch_array($result, MYSQL_ASSOC);
$TotalPoints = $row['reward_user_points'];
if (@mysql_affected_rows($dbc) == 1) { // Whohoo!
$new_credit = $TotalPoints + $p;
$query = "UPDATE reward_points SET reward_user_points ='$new_credit' WHERE users_id = $a";
$result = @mysql_query($query);
}
?>
答案 0 :(得分：0)
好的，我不得不说我不太清楚你的麻烦是什么。你说你在将新点添加到积分总计字段时遇到了麻烦，但是你可以更具体一点吗？ php或mysql是否有任何错误消息？
