警告：mysql_fetch_array() 需要参数 1 && 警告：无法修改标头信息 - 标头已发送

Question

我的 config.php 文件出现错误，它在 1 天前开始给我错误。 所以错误是：

警告：mysql_fetch_array() 期望参数 1 是资源，布尔值在第 32 行的 /home/x/public_html/rx/includes/config.php 中给出

警告：无法修改标头信息 - 标头已由 /home/x/public_html/rx/includes/config.php 中的（输出开始于 /home/x/public_html/rx/includes/config.php:32）发送第 38 行

我的配置 php 文件是下一个：

<?php
session_start();
include 'connection.php';
include 'functions.php';

$logged_in = 0;
if(isset($_SESSION['username']) && isset($_SESSION['password'])){
    $username = sec($_SESSION['username']);
    $password = sec($_SESSION['password']);

    $udata = get_row("SELECT * FROM playeraccounts WHERE playerName='$username' && playerPassword='$password'");
    if(isset($udata['playerID']))
    {
        $logged_in = 1;
        if(isset($_GET['logout']))
        {
            unset($_SESSION['username']);
            unset($_SESSION['password']);
            mysql_query("UPDATE playeraccounts SET rpgon=0 WHERE playerName='$username'"); 
            header('location: index.php');
        }
    }
}
function redirect_not_logged()
{
    $username = sec($_SESSION['username']);
    $password = sec($_SESSION['password']);

    $udata = get_row("SELECT * FROM playeraccounts WHERE playerName='$username' && playerPassword='$password'");
    $id = $udata['playerID'];
    $q = mysql_query("SELECT * FROM `playeraccounts` WHERE playerID = $id");
    while($row = mysql_fetch_array($q))
    {
         $rpg = $row['rpgon'];
    }
    if($rpg == 0) 
    { 
        header('location: login.php');
    }

}

我找不到问题所在，redirect_not_logged 函数也不再工作，因为我收到了这 2 个错误..
