使用PHP将数字值添加到两个MySQL数据库行中

Question

我有一个网站，登录的用户可以在其中累积积分，然后可以通过购物车购买积分。下面的页面是一个管理员php功能，管理员可以在该功能中为单个用户提供点数（现在每次只有一位用户）。

有三个表参与此脚本：

用户：包含用户的详细信息

tally_point：所有点交易店，传入和订货

reward_points ：存储用户拥有的积分总数

脚本通过下拉菜单获取用户的详细信息，并添加指向理货点表确定，但....

 <?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'); 

     // Set the page title and include the HTML header. 
     $page_title = 'Add Points to User';

...具有获得新的点加到点麻烦林全部字段（reward_user_points）在reward_points表中，我有一些代码在下面，但林不知道我应该把它放在哪里，如果有人有任何建议，请让我知道。

<?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); 
     } 
    ?>

好吧，我不得不说，我不明白你的麻烦是什么。你说你在添加总点数的新点上遇到了麻烦，但是你能否更具体些？有没有PHP或MySQL返回的错误信息？
