<?php
class Gallery extends Controller{
    function Gallery(){
        parent::Controller();
        $this->load->library('form_validation');
        $this->load->model('gallery_mdl');
    }
    
    function index(){
        //display gallery view of all theediffrent galleries
        
    }
    
    function addPhoto(){
        //upload new photo
        if($this->session->userdata("UserID")){    
            if($this->gallery_mdl->getGalleries())
                $data['galleries']=$this->gallery_mdl->getGalleries();
            else
                $data['galleries']=NULL;
                
            $this->form_validation->set_rules('title','Title','trim|max_length[20]|xss_clean');
            $this->form_validation->set_rules('image', 'Image', 'required|callback__do_upload');
            $this->form_validation->set_rules('gallery','Gallery', 'required');
                        
            if($this->form_validation->run()){
            
            }
            
            
            $this->template->write('title',"Add Photo | Dalnavert Kennels");
            $this->template->write_view('content',"admin/add_photo", $data);
            $this->template->render();
        }
        else{

            $this->template->write_view('content',"Access_Denied");
            $this->template->render();
        }
    }
    
    function addGallery(){

            $this->validation->set_rules($rules);
            $fields['gallery'] = 'Gallery';
            $this->validation->set_fields($fields);
            $this->validation->set_error_delimiters('<li>', '</li>');
            if($this->validation->run()){
                $insert_gallery = $this->gallery_mdl->addGallery($this->validation->gallery);
                if($insert_gallery){
                    $this->session->set_flashdata("GalleryAddConfirmation", $this->validation->gallery." has been added to the list of galleries.");
                    redirect('gallery/addGallery');
                }
                else{
                    $this->session->set_flashdata("GalleryAddConfirmation", $this->validation->gallery." has not ben added. An Error occurred upon trying to insert it into the database. Contact Administrator.");
                    redirect('gallery/addGallery');
                }
                
            }
            $this->template->write('title',"Add Gallery | Dalnavert Kennels");
            $this->template->write_view('content',"admin/add_gallery", $data);
            $this->template->render();
        }
        else{
            $this->template->write('title',"Access Denied");
            $this->template->write_view('content',"Access_Denied");
            $this->template->render();
        }
    }
    
    /*-----------------Callback Functions--------------------*/
    function _do_upload($file)
    {
        $config['upload_path'] = './public/images/temp_images/';
        $config['allowed_types'] = 'jpg|jpeg|png|gif';
        $this->load->library('upload', $config);
            
        if ( ! $this->upload->do_upload('image'))
        {
            // set the validation error using the errors provided by the upload class
            $this->form_validation->set_message('_do_upload', $this->upload->display_errors());
            return FALSE;
        }    
        else
        {
            return TRUE;
        }
    }
}

File upload in view is called image.

in my controller , I haven't done anything past running the validation as I want to get that working first.

thanks!
