php - PHP 查询 LIMIT DESC 无法正常工作

Question

我正在尝试获取玩过我的游戏的玩家的高分（前 10 名）列表。一切正常，除了一件事，列表不正确。前 10 个人是正确的，但是当我转到第 2 页时，列表并没有进一步完成。

变量解释

$gamemode = "Endless"
$filter = "Score"
$startNum = Page1 = 0, Page2 = 10
$maxlimit = 10

询问：

$query = "SELECT ID, Gamemode, Name, Score, ContainersSaved, TimePlayed, Date, ScorePerMinute
FROM $dbName . `highscore`
WHERE Gamemode='$gamemode'
ORDER by `$filter` DESC
LIMIT $startNum, $maxlimit";

有谁知道我做错了什么？

Answer 1

If your Score field is varchar try: (or change it to INT)

$order=$filter;
if($filter=='Score') {
    $order="ABS($filter);
}
$query = "SELECT ID,Gamemode,Name,Score,ContainersSaved,TimePlayed,Date,ScorePerMinute FROM $dbName . `highscore` WHERE Gamemode='$gamemode' ORDER by $order DESC LIMIT $startNum, $maxlimit";

Answer 2

我修复了它，我忘记将“分数”字段从 varchar 更改为 INT，所以它试图在字符串而不是 INT 上下降。
