Email Class in Codeigniter Using Form - php

Question

Disclaimer: I'm new to web develoment.
Scenario: I've created a contact form, and I'm trying to pass the input into the email class functions used in CodeIgniter. I am receiving undefined variable errors when the form is submitted. Email library is autoloaded for reference. It's late, and I may be overlooking something easy, but it doesn't hurt to post. Thanks a lot for all of your help!
Controller:
public function index()
{
//form validation
$this->form_validation->set_rules('email', 'Email Address', 'trim|required|valid_email');
$this->form_validation->set_rules('subject', 'Subject', 'required');
$this->form_validation->set_rules('message', 'Message', 'required');
$this->data['email'] = array(
'name' => 'email',
'id' => 'email',
'type' => 'text',
'value' => $this->form_validation->set_value('email'),
);
$this->data['subject'] = array(
'name' => 'subject',
'id' => 'subject',
'type' => 'text',
'value' => $this->form_validation->set_value('subject'),
);
$this->data['message'] = array(
'name' => 'message',
'id' => 'message',
'type' => 'text',
'value' => $this->form_validation->set_value('message'),
);
if ($this->form_validation->run() == true)
{
$this->email->from($email);
$this->email->to('support#example.com');
$this->email->subject($subject);
$this->email->message($message);
$this->email->send();
redirect('contact/success');
}
else
{
$this->data['error_message'] = (validation_errors()) ? validation_errors() : $this->session->flashdata('error_message');
$title['title'] = 'Contact';
$this->load->view('public/head_view', $title);
$this->load->view('public/header_view');
$this->load->view('public/contact_view', $this->data);
$this->load->view('public/footer_view');
}
View:
<div id="infoMessage"><?php echo $error_message;?></div>
<?php $attritubes = array('class' => 'nice'); ?>
<?php echo form_open('contact'); ?>
<p>Email Address:<br />
<?php echo form_input($email); ?>
</p>
<p>Subject:<br />
<?php echo form_input($subject); ?>
</p>
<p>Message:<br />
<?php echo form_textarea($message); ?>
</p>
<p><?php echo form_submit('submit', 'Submit'); ?></p>
<?php echo form_close(); ?>

Well, you barely define any variable here:
if ($this->form_validation->run() == true)
{
$this->email->from($email);
$this->email->to('support#example.com');
$this->email->subject($subject);
$this->email->message($message);
$this->email->send();
redirect('contact/success');
}
Where do $email, $subject, $message come from?
You might want to use something like (but I suggest you do better :))
$email = $this->input->post('email');
$subject = $this->input->post('subject');
$message = $this->input->post('message');
Also, make sure you've loaded the email library before calling it, and that you load the view in your else{} part (since you omitted it I cannot tell)
