Hello all !

I still have an error on my script for Maniaconnect, and still don't understand why. Kimi and me tried a lot of things !

Code: Select all

<?php session_start();
			
			$api_username='*****|********';
			$api_password='*******';
			
			require_once __DIR__ . '/maniaplanet-ws-sdk/libraries/autoload.php';
			define('API_USERNAME', $api_username);
			define('API_PASSWORD', $api_password);
			define('SCOPE', '');

			try
			{
				$trackmania = new \Maniaplanet\WebServices\ManiaConnect\Player(API_USERNAME, API_PASSWORD);
			
				// URLs to log in and out
				$loginURL = $trackmania->getLoginURL(SCOPE);
				$logoutURL = $trackmania->getLogoutURL();
				
				if(isset($_POST['logout'])) {
					$trackmania->logout();
					header('Location: '.$logoutURL);
					exit;
				}

				// Retrive player information. If the user is not logged in, it will return false
				$player = $trackmania->getPlayer();

			}
			catch(\Maniaplanet\WebServices\Exception $e)
			{
				$player = null;
			}
			if ($player) {
				$_SESSION['player_login']=$player->login;
				$_SESSION['player_nickname']=$player->nickname;
				$_SESSION['player_path']=$player->path;
				$_SESSION['player_id']=$player->id;
			}
			else {
				$_SESSION['player_login'] = 'BUG';
			}
			
		header("Content-type: application/xhtml+xml"); echo "<?xml version='1.0' encoding='utf-8'?>\n";
		echo '<manialink>';
		
		echo '<label posn="0 0 5" text="' . $_SESSION['player_login'] . '"/>';
		echo '<timeout>0</timeout>';
		echo '</manialink>';
		
?>

We don't see the window to allow player to identify. $_SESSION['player_login'] return BUG.
Do you have an idea ?

Thanks.

You never use $loginURL, hence the player is never authentified, so $player is always null.

You either have to put a "login" link that points to $loginURL or to make a redirection to login $URL whenever $player is false (you should be careful about infinite redirect loop though).

Okay I think I understood why we have to put htmlentities($loginURL).

Thanks for your help again

Just a quick note about htmlentities, since I had a bug with it a couple days ago.

You want to use htmlentities to encode your data inside the xml attributes and tags. For example let's say your nickname is "<manialink>". If you put your data in the XML (or HTML) without encoding it you might end up with:

Code: Select all

<manialink>
    <label text="<manialink>" />
</manialink>

This is invalid XML, but I think the Manialink browser will still display it. However if your nickname is ""</manialink>" (note the double quote) your page will be messed up:

Code: Select all

<manialink>
    <label text=""</manialink>" />
</manialink>

So you want to use htmlentities to safely encode all data and avoid XML errors.

However, htmlentites uses ISO8859-1 charset by default, and that will fail with most special characters (that, let's be honest, are found in most Maniaplanet nicknames, including mine

).

So be sure to force htmlentities() to use UTF-8, like that:

Code: Select all

htmlentities($some_data, ENT_COMPAT, 'UTF-8');

All in all, here's a little example:

Code: Select all

<?php $nickname = 'gà¹uxim ãƒ„$o$3c0ï¸½$z$c3fnAdeo$o$3c0ï¸¾'; ?>
<manialink>
    <label text="<?php echo htmlentities($nickname, ENT_COMPAT, 'UTF-8'); ?>" />
</manialink>

Hope it helps
