CodeIgniter Multiple File Upload

[ShoeLace1291]

I have a form where a user can upload photos to their gallery.  I want them to be able to upload more than one photo at a time.  So in my upload form, I have a file input called "files[]" along with a javascript code that let's them add more file fields with the same name. 

 

The PHP script that I have made goes through several steps.  First, it goes through the process of the actual file upload.  If the file upload is a success, it then creates an attachment file(as a database record) and then it creates the photo record in the database.  When I return the upload data array, none of the array keys have any values.  The display_errors function doesn't return any errors, either.  Any ideas?

 

    $this->load->library('form_validation');
    $this->form_validation->set_rules('files', 'Choose File', 'required');
    if($this->form_validation->run() == FALSE){
        $data = array(
                    'ALBUM_TITLE' => $album['ALBUM_TITLE'],
                    'FORM_OPEN' => form_open('gallery/photos/upload/'.$this->uri->segment(4)),
                    'VALIDATION_ERRORS' => validation_errors()
                    );
        $this->parser->parse('gallery/photo_upload.tpl', $data);
    } else {
        $limit = count($this->input->post('files'));
        $photo_ids = '';
        for($i=0;$i<=$limit;$i++){
            $config = array(  //Preferences to validate the image before uploading it
                    'upload_path' => './attachments',
                    'allowed_types' => 'jpg|gif|bmp',
                    'max_size' => '100',

                    'encrypt_name' => TRUE,
                    'remove_spaces' => TRUE
                    );
            $this->load->library('upload', $config);
            if($this->upload->do_upload('files['.$i.']')){
                $file = $this->upload->data();
                $info = array(  //Information to pass to the attachment class for creation

                        );
                if($this->attachment->create($info)){

                            'date_posted' => now(),
                            'attachment_id' => $this->attachment->insert_id
                            );
                    if($this->photo->create($info)){
                        $photo_ids[] = $this->photo->insert_id;
                        $photo_errors = 0;
                    } else {
                        $photo_errors = $photo_errors + 1;
                    }
                } else {
                    $attachment_errors = $attachment_errors + 1;
                }
            } else {
                    $this->upload->display_errors('<p>', '</p>');
