Question

我目前正在构建排行榜（https://mgo.io/mgo3/leaderboard.php），而且我在手动接受数据方面遇到了问题。我希望它从我的MySQL数据库中获取数据，并允许我手动输入并输入数据，它也将显示。它目前抓住了部族db的id和部族名称。

如何让它读取我从两个新的＆＃39;胜利中输入的数据？和＆＃39;损失＆＃39;我在db中添加的列已经从？

中获取数据

继承我的代码：

<?php

include_once "Log.class.php";
include_once "dbcon.php";

function getLeaders() {
    global $dbh;

    date_default_timezone_set('UTC');

    $res = array();

    $stmt = $dbh->prepare("SELECT id, name FROM clans ORDER BY id ASC");
    $stmt->execute();
    while ($row = $stmt->fetch()) {
        $clan_id = (int) $row['id'];
        $clan_name = $row['name'];

        $res[$clan_id] = array();
        $res[$clan_id]['name'] = $clan_name;
        $res[$clan_id]['rank'] = 0;
        $res[$clan_id]['cp'] = 0;
        $res[$clan_id]['win'] = 0;
        $res[$clan_id]['loss'] = 0;

只需将字段添加到SELECT语句中，并将检索到的值分配给适当的变量：

// Add wins & losses here:
$stmt = $dbh->prepare("SELECT id, name, wins, losses
                       FROM clans ORDER BY id ASC");
$stmt->execute();
while ($row = $stmt->fetch()) {
    $clan_id = (int) $row['id'];
    $clan_name = $row['name'];

    $res[$clan_id] = array();
    $res[$clan_id]['name'] = $clan_name;
    $res[$clan_id]['rank'] = 0;
    $res[$clan_id]['cp'] = 0;
    $res[$clan_id]['win'] = $row['wins'];    // <<<< and here...
    $res[$clan_id]['loss'] = $row['losses']; // <<<<

如何让排行榜获取正确的数据？
