Counting Num_rows after SELECT for login

[Eggzorcist]

I'm creating a login that uses PDO statements, however when I try to count how many rows was selected, it gives me an error mentioning its an unidentified property, I always tried rowCount, but it did not work either...

 

Notice: Undefined property: PDOStatement::$num_rows in /Users/JPFoster/Sites/Jaipai.Blog/engine.php on line 50

 

 

Here's my class method:

 public function login($user, $pw){
	$user = addslashes($this->user);
	$pw = md5($pw);

	$query = "SELECT * FROM `users` WHERE `username` = '".$user."' AND `password` = '".$pw."'";

	//set up query
	$results = $this->pdo->query($query);


	if ($results->num_rows == 1){
	$row = $results->fetch_assoc();
	echo "Worked!";
		//$this->set_session($row['id'], $row['username'], $row['email']);
	} else {

	echo "Your Username and Password did not match"; 	

	}

	//if user + passs match { redirect (member page) and set up sessions

	// Else ... Retry...
}	

 

 

Any help with this will be greatly appreciated!

Solved, using fetchColumn() instead.
