[SOLVED] Warning: mysqli_connect()

[chokk]

Hey,I'm trying to learn OOPHP. I keep running into problems I can't quite figure out, because OOP is a totally new concept to me.

//classes.phpclass testSys{	protected $host = 'localhost';	protected $user = 'root';	protected $pass = '';	protected $db = 'system';		function __construct(){		$connect = mysqli_connect($this->host, $this->user, $this->pass, $this->db);		if(!$connect){			echo '<p style="color:red;">Connection problems!</p>';		}		else{			echo '<p style="color:red;">Connection established!</p>';		}	}		function doConnect(){		$connect = mysqli_connect($this->host, $this->user, $this->pass, $this->db) or die('Connection problems.');		mysqli_set_charset($connect, 'utf-8');		return $connect;	}		function doFilter($data){		$data = htmlspecialchars($data);		$data = trim($data);		$data = stripslashes($data);		$data = preg_replace("#'#", "'", $data);		$data = preg_replace("#`#", "‘", $data);		$data = preg_replace('#"#', """, $data);		return $data;	}}

And here's the error I'm getting:

Warning: mysqli_connect() [function.mysqli-connect]: (28000/1045): Access denied for user 'SYSTEM'@'localhost' (using password: NO) in C:\wamp\www\test\classes.php on line 10Connection problems!Warning: mysqli_connect() [function.mysqli-connect]: (28000/1045): Access denied for user 'SYSTEM'@'localhost' (using password: NO) in C:\wamp\www\test\classes.php on line 20Connection problems.

you did not filled up password i think. make sure host,password,user are correct and database name already exist.

There is no password and the database does exist. I have a subclass that extends from this main class which posts data to a table within the database. It worked yesterday but now it doesn't. I created a new subclass to read data from another table and now it doesn't connect...?Oh wait here's the thing. I accidentally changed the variables containing the login information from within the subclass. D'oh!
