Question

好吧，我有一個成就係統，除了正確加分之外，它的效果很好。這裏是一個例子，如果條件滿足，更新到數據庫：

if($members['Active']==1){  
    $Achievement1=mysql_query("SELECT * FROM ". 
            "myachievements WHERE ". 
           "Handle='$members[Handle]' and AchievementId='1'"); 
    $Achievement2=mysql_num_rows($Achievement1); 
    $tehdate=date('Y-m-d'); 
    $Points = '50'; 
    $newscore=$members['Points']+$Points; 
    if ($Achievement2 == 0) {   
     mysql_query("INSERT INTO `myachievements` 
         (`Handle` , `AchievementId` , `Date`) VALUES 
          ('$members[Handle]', '1' , '$tehdate')" 
        )or die(mysql_error()); 

     mysql_query ("UPDATE members SET Achievement = 'Y' WHERE ". 
         "Handle = '$members[Handle]'")or die(mysql_error()); 
     mysql_query ("UPDATE members SET Points = '$newscore' WHERE ". 
         "Handle = '$members[Handle]'")or die(mysql_error()); 
    } 

} 

上面顯示的成績僅用於激活一個帳戶。我現在大約有35項成就，每項成績都有不同的ID。所以在我的主要包含文件中有兩組if語句。我的成員表中的測試用戶配置文件已滿足35項成就中總共19項的條件。除了添加點之外，所有數據庫都會正確更新。總分應該高出約1000分，但總是給我150分。我不知道我做錯了什麼。任何幫助，將不勝感激。

我不能說具體爲什麼不加點，移動數據庫的東西到它自己的功能後，我會說這是因爲你不會增加，存儲在$members['Points']基點值：

if($members['Active']==1) 
{ 
    $Points = '50'; 
    $newscore = $members['Points'] + $Points; 

    if (0 == achievement_get_count($members['Handle'], 1)) 
    { 
    achievement_add($members['Handle'], 1, date('Y-m-d')); 
    achievement_set_points($members['Handle'], $newscore); 
    } 
} 

/** achivement mysql functions */ 

function achievement_get_count($memberHandle, $achievementId) { 
    $Achievement1=mysql_query("SELECT * FROM myachievements WHERE Handle='$memberHandle' and AchievementId='$achievementId'"); 
    return mysql_num_rows($Achievement1); 
} 

function achievement_add($memberHandle, $achievementId, $date) { 
    mysql_query("INSERT INTO `myachievements` (`Handle` , `AchievementId` , `Date`) 
    VALUES (
     '$memberHandle', '$achievementId' , '$date')") 
    or die(mysql_error()); 
} 

function achievement_set_points($memberHandle, $points) { 
    mysql_query ("UPDATE members SET Achievement = 'Y', Points = '$points' WHERE Handle = '$memberHandle'")or die(mysql_error()); 
}
