Uploading File and Saving File Name To DB with Doctrine

[eluser]Unknown[/eluser]
Brand new to code igniter, but I'm really enjoying how easily you can just jump right in.

I'm working on a project where I need to upload a file and save the file name to a database along with some metadata from drop downs.

I have the form working in so far as it uploads the file and creates the record, but doesn't seem to get the path name right.

In the Controller:

Code:

public function submit()
    {
    $this->load->model('admin_model');
        if($this->_submit_validate() == FALSE)
        {
            $this->add();
            return;            
        }
        else
        {
            $this->admin_model->do_upload();
            
            $region = new Region();
            $region->plane = $this->input->post('plane');
            $region->region = $this->input->post('region');
            $region->save();
            
            $p = new Photo();
            $p->photo_path = $this->input->post('userfile');
            $p->Region = $region;
            $p->save();
            
        }
        redirect('/admin/add/');
        
    }
    
    private function _submit_validate()
    {
        $this->form_validation->set_rules('plane', 'Plane', 'required');
        $this->form_validation->set_rules('region', 'Region','required');
        return $this->form_validation->run();
    }

In the model:

Code:

<?php

class Admin_model extends Model
{
    var $gallery_path;
    
    function Admin_model()
    {
        parent::Model();
        
        //$this->gallery_path = realpath(APPPATH . '../images');//Couldn't get this working for whatever reason
        $this->gallery_path = "C:\\wamp\\localpath\\images\\";
    }
    
    function do_upload()
    {
        $config = array(
            'allowed_types' => 'jpg|jpeg|png|gif',
            'upload_path' => $this->gallery_path
        );
        $this->load->library('upload', $config);
        $this->upload->do_upload();
    }
}

So really, 2 questions right now.

1. When I submit a file it uploads correctly and creates a new record and a new region tag for the photo, however the photopath name in the db is saved as 'x^' (I do have the doctrine model set up as a gzip field, but don't think this should matter?)

2. How can I move all the validation to the model and have it validate the upload and the form and THEN return all the errors.

Many thanks. CI is a lot of fun.
