Insert into not creating new row - php

Question

I've been trying to mess around with a registration system. However when I try to insert the information into the database. no new row is generated. I'm not getting any errors, and my code seems legitimate. Is there something that I don't know about INSERT INTO?
$username = $_POST['regusername'];
$email = $_POST['regemail'];
$password = $_POST['regpassword'];
$cpassword = $_POST['regpasswordcon'];
$firstname = $_POST['regfirstname'];
$lastname = $_POST['reglastname'];
//check username for weird symbols
if (preg_match('/[\'^£$%&*()}{##~?><>,|=_+¬-]/', $username)){
// one or more of the 'special characters' found in string
//header("Location: /register.php");
echo "Your username should only contain letters and numbers";
exit;
}
//check if username is taken
$check = $con->prepare("SELECT * FROM accounts WHERE username=:user");
$check->bindParam(':user',$username);
$check->execute();
$result = $check->fetch(PDO::FETCH_ASSOC);
if(!empty($result)){
//header("Location: /register-page.php"); //direct browser back to sign in
echo "User is already taken";
exit;
}else{ //otherwise proceed to register new user
//Hashing of password
$hpassword = password_hash($password, PASSWORD_DEFAULT);
//Prepared statements for SQL injection prevention
$query = $con->prepare("INSERT INTO accounts (username, password, email, firstname, lastname) VALUES (:name,:hpassword,:email,:fname,:lname) ");
//bind parameters
$query->bindParam(':name',$username);
$query->bindParam(':hpassword',$hpassword);
$query->bindParam(':email',$email);
$query->bindParam(':fname',$firstname);
$query->bindParam(':lname',$lastname);
$query->execute();
}
