kinda works :o

<?php
class Connect
{
	public function __construct()
	{
		try
			{
				$this->db = new PDO("mysql:host=localhost;dbname=aaron_test",'aaron_test','d6G4X5S54');
			}
		catch(PDOException $e)
		{
			echo $e->getMessage();
		}
	}

	public function login($name, $pass)
	{
		if(!empty($name) && !empty($pass))
		{
			$st = $this->db->prepare("SELECT * FROM users WHERE username= ? and password= ?");
			$st->bindParam(1, $name);
			$st->bindParam(2, $pass);
			$st->execute();

			if($st->rowCount() == 1)
			{
				echo "Access Granted.";
			}
			else
				{
					echo "incorrect username or password.";
				}
		}
		else
			{
				echo "Please supply a username and password.";
			}
	}

}

if(isset($_POST['submit']))
{
	$name = $_POST['user'];
	$pass = $_POST['pass'];

	$object = new Connect();
	$object->login($name, $pass);
}
 ?>



 <form action="" method="POST">
 	Username: <input type="text" name="user">
 	Password: <input type="text" name="password">
 	<input type="submit" name="submit" value="Login">
 </form>
