SteamAuthentication

SteamAuthentication is a basic set of PHP files that enable users to login using their steam account to view protected content on your website. it creates a session using their steamid as the sessionID and checks for the session when a user visits the page. It also includes a file which allows you to use their profile information such as their avatar and online status.

To Install

Upload the steamauth folder.

Open up SteamConfig.php

Now in the page that you would like to use the steamauth library, add the following at the top:

<?php

require 'steamauth/steamauth.php';

?>

And where you want the protected content to be:

<?php
if(!isset($_SESSION['steamid'])) {

    loginbutton(); //login button

}  else {

    include ('steamauth/userInfo.php'); //To access the $steamprofile array
    //Protected content

    logoutbutton(); //Logout Button
}     
?>

By default, the logout & login buttons reload the current page, this can be changed in the SteamConfig file.

Be aware that naming a file in your webpage root like any file in the steamauth folder will break SteamAuth.

Choosing a login button style

by default loginbutton(); will display image

You can choose the style of the login button by specifying a variable like the following:

loginbutton("rectangle");

image

loginbutton(); -OR- loginbutton("square");

Using Profile Variables

I have created a userInfo.php file which creates an array of ready to use variables that includes profile information of the steam user that has logged in:

Please note that some of these variables may be unavailable for some users as it depends on their privacy settings.

Update User Information

To refresh a user's Steam profile data use: html: <a href="?update">update</a> - recommended -OR- php: $_GET['update']=true; - this must be set before require 'steamauth/steamauth.php';

Automatically refresh Steam profile data if older than specified time when they next visit your site

change line 67 of steamauth.php From:

if (isset($_GET['update'])){

To:

if (isset($_GET['update']) || !empty($_SESSION['steam_uptodate']) && $_SESSION['steam_uptodate']+(24*60*60) < time()){
