I'd like to have the Steam API Installed on my forum. It would be such an improvement if my users can just sign in with their Steam Account. Since the openID plugin is autdated, i need someone who wants to install it on my site. The code that should be integrated is:
Code: Select all
<?php
/**
*
* @package Steam Community API

* @license http://opensource.org/licenses/mit-license.php The MIT License

*/
class SteamSignIn
{
const STEAM_LOGIN = 'https://steamcommunity.com/openid/login';
/**
* Get the URL to sign into steam
*
* @param mixed returnTo URI to tell steam where to return, MUST BE THE FULL URI WITH THE PROTOCOL
* @param bool useAmp Use & in the URL, true; or just &, false.
* @return string The string to go in the URL
*/
public static function genUrl($returnTo = false, $useAmp = true)
{
$returnTo = (!$returnTo) ? (!empty($_SERVER['HTTPS']) ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . $_SERVER['SCRIPT_NAME'] : $returnTo;
$params = array(
'openid.ns' => 'http://specs.openid.net/auth/2.0',
'openid.mode' => 'checkid_setup',
'openid.return_to' => $returnTo,
'openid.realm' => (!empty($_SERVER['HTTPS']) ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'],
'openid.identity' => 'http://specs.openid.net/auth/2.0/identifier_select',
'openid.claimed_id' => 'http://specs.openid.net/auth/2.0/identifier_select',
);
$sep = ($useAmp) ? '&' : '&';
return self::STEAM_LOGIN . '?' . http_build_query($params, '', $sep);
}
/**
* Validate the incoming data
*
* @return string Returns the SteamID64 if successful or empty string on failure
*/
public static function validate()
{
// Star off with some basic params
$params = array(
'openid.assoc_handle' => $_GET['openid_assoc_handle'],
'openid.signed' => $_GET['openid_signed'],
'openid.sig' => $_GET['openid_sig'],
'openid.ns' => 'http://specs.openid.net/auth/2.0',
);
// Get all the params that were sent back and resend them for validation
$signed = explode(',', $_GET['openid_signed']);
foreach($signed as $item)
{
$val = $_GET['openid_' . str_replace('.', '_', $item)];
$params['openid.' . $item] = get_magic_quotes_gpc() ? stripslashes($val) : $val;
}
// Finally, add the all important mode.
$params['openid.mode'] = 'check_authentication';
// Stored to send a Content-Length header
$data = http_build_query($params);
$context = stream_context_create(array(
'http' => array(
'method' => 'POST',
'header' =>
"Accept-language: en\r\n".
"Content-type: application/x-www-form-urlencoded\r\n" .
"Content-Length: " . strlen($data) . "\r\n",
'content' => $data,
),
));
$result = file_get_contents(self::STEAM_LOGIN, false, $context);
// Validate wheather it's true and if we have a good ID
preg_match("#^http://steamcommunity.com/openid/id/([0-9]{17,25})#", $_GET['openid_claimed_id'], $matches);
$steamID64 = is_numeric($matches[1]) ? $matches[1] : 0;
// Return our final value
return preg_match("#is_valid\s*:\s*true#i", $result) == 1 ? $steamID64 : '';
}
}So, if anyone of you has an idea how to do this, and wants to help me with this, that would be great! If you want, I can pay for it (as long as it's not a fortune xD).

Indeed, I can only try it.
