Attaching a file, sending with Email class

[eluser]Unknown[/eluser]
Hey all. I'm pretty frustrated at this point. I have spent way too long trying to figure something out, that I know must be simple!

I simply want to attach and send a file in an email, through a form. I am sure my code isn't the best, but here is the controller.

Code:

<?php

class Form extends Controller {
    
    function index()
    {
        $this->load->helper(array('form', 'url'));
        $this->load->library('email');
        $this->load->library('validation');
        
        $rules['name']    = "required";
        $rules['phone']    = "required|alpha_dash";
        $rules['email']    = "required|valid_email";        
        $this->validation->set_rules($rules);
        $this->validation->set_error_delimiters('<div class="error">', '</div>');
        
        $fields['name'] = 'Name';
        $fields['organization'] = 'Organization';
        $fields['phone'] = 'Phone';
        $fields['email'] = 'Email';
        $fields['quantity'] = 'Quantity';
        $fields['message'] = 'Message';

        $this->validation->set_fields($fields);
        
        $service = "";
            
            $services = $this->input->post('services');
            for($i=0;$i<(count($services));$i++) {
                $service .= ($services[$i].", ");
                //echo $services[$i].", ";
            }
        
        $name = $this->input->post('name');
        $email = $this->input->post('email');
        $organization = $this->input->post('organization');
        $phone = $this->input->post('phone');
        $quantity = $this->input->post('quantity');
        $artwork = $this->input->post('artwork');
        $message = $this->input->post('message');
        
        if ($this->validation->run() == FALSE)
        {
            $this->load->view('getQuoteForm');
        }
        else
        {
            $this->email->from($email, 'SoWhachaWant.com');
            $this->email->to('[email protected], [email protected]');
            $this->email->subject('Quote Request');
            $this->email->message("Name: ".$name."\r\nOrganization: ".$organization."\r\nPhone #: ".$phone."\r\nEmail Address: ".$email."\r\nQuantity Nedded: ".$quantity."\r\nServices Needed: ".$service."\r\nMessage: ".$message);
            if($artwork) {
                           $this->email->attach($artwork);
                           echo $artwork;
                        }

            $this->email->send();
            
            $this->load->view('formsuccess');
        }
    }
}
?&gt;

Before I added the attachment code, the form properly displayed validation error, and sent correctly.

Now, it will take a second, like it's loading the attachment, and most of the time displays a success message. If I don't attach a file, it actually shoots the email. If I attach a file it does not send. AND, I only got an error message once. It said I had improper parameters.

Any help? I would be most grateful.
