Help with an error.

[JSHINER]

<?php 
class Auth {

function _authenticate($db, $username, $password) {
	if (!ValidText::username($username)) {
		return false;
	}
	if (!ValidText::password($password)) {
		return false;
	}
	return $db->getRow('SELECT * FROM users WHERE username = \'' . $db->escape($username) . '\' AND password = \'' . $db->escape(md5($password)) . '\'');
}
?>

 

How come with the above code I get the error:

 

"Fatal error: Call to a member function getRow() on a non-object in /home/..."

Can you show us the $db class?

<?php
function getRow($query) {
	$result = $this->query($query);
	$row = false;
	if ($result) {
		$row = mysql_fetch_assoc($result);
		mysql_free_result($result);
	}
	return $row;
}
?>

Am I missing something here? I can't figure this one out. I've gone through all of my code and everything seems fine.

where is $db declared?
