php - 通知 : Undefined index: buttonstyle in

Question

我正在运行一个 PHP 脚本，当我在我的 VPS 上而不是在 web-server 上托管文件时出现此错误.

这里是错误:

Notice: Undefined index: buttonstyle in C:\xampp\htdocs\steamauth\steamauth.php on line 19

这是脚本 (C:\xampp\htdocs\steamauth\steamauth.php)

<?php
 ob_start();
 session_start();
 require ('openid.php');

 function logoutbutton() {
echo "<form action=\"steamauth/logout.php\" method=\"post\"><input value=\"Logout\" type=\"submit\" /></form>"; //logout button
}

function steamlogin()
{
try {
require("steamauth/settings.php");
$openid = new LightOpenID($steamauth['domainname']);

$button['small'] = "small";
$button['large_no'] = "large_noborder";
$button['large'] = "large_border";
$button = $button[$steamauth['buttonstyle']];

if(!$openid->mode) {
    if(isset($_GET['login'])) {
        $openid->identity = 'http://steamcommunity.com/openid';
        header('Location: ' . $openid->authUrl());
    }
//echo "<form action=\"?login\" method=\"post\"> <input type=\"image\" src=\"http://cdn.steamcommunity.com/public/images/signinthroughsteam/sits_".$button.".png\"></form>";
}

 elseif($openid->mode == 'cancel') {
    echo 'User has canceled authentication!';
} else {
    if($openid->validate()) { 
            $id = $openid->identity;
            $ptn = "/^http:\/\/steamcommunity\.com\/openid\/id\/(7[0-9]{15,25}+)$/";
            preg_match($ptn, $id, $matches);

            $_SESSION['steamid'] = $matches[1]; 
            include_once("set.php");
            $query = mysql_query("SELECT * FROM users WHERE steamid='".$_SESSION['steamid']."'");
            if (mysql_num_rows($query) == 0) {
                mysql_query("INSERT INTO users (steamid) VALUES ('".$_SESSION['steamid']."')") or die("MySQL ERROR: ".mysql_error());
            }
            if (isset($steamauth['loginpage'])) {
                header('Location: '.$steamauth['loginpage']);
            }
    } else {
            echo "User is not logged in.\n";
    }

}
} catch(ErrorException $e) {
echo $e->getMessage();
}
}

?>

这里是steamauth/settings.php的代码

<?php
 $steamauth['apikey'] = "CANT SAHRE IT. PRIVATE"; // Your Steam WebAPI-Key found at http://steamcommunity.com/dev/apikey
 $steamauth['domainname'] = "CANT SAHRE IT. PRIVATE"; // The main URL of your website displayed in the login page
 $steamauth['logoutpage'] = ""; // Page to redirect to after a successfull logout (from the directory the SteamAuth-folder is located in) - NO slash at the beginning!
 $steamauth['loginpage'] = "/"; // Page to redirect to after a successfull login (from the directory the SteamAuth-folder is located in) - NO slash at the beginning!
?>

Answer 1

在您的 setting.Php 文件中，$steamauth['buttonstyle'] 没有可用的索引。

解决方案:

您需要在 setting.php 文件中定义 $steamauth['buttonstyle'] 您所需的值:

$steamauth['apikey'] = "CANT SAHRE IT. PRIVATE";

$steamauth['domainname'] = "CANT SAHRE IT. PRIVATE"; 

$steamauth['logoutpage'] = "";

$steamauth['loginpage'] = "/";

$steamauth['buttonstyle'] = "value that you need"; // add this index

为这个 URL 设置你需要的 buttonstyle index 的值:

http://cdn.steamcommunity.com/public/images/signinthroughsteam/sits_".$button.".png
