File upload validation

[eluser]stef25[/eluser]
ive certainly progressed, thanks! im just wondering now how to get $image_data = $this->upload->data(); back to the create() function from where the _do_upload callback is called.

i return $image_data, but its not available in create(). do you have to declare $image_data as private, public, ... ? if so, where?

thanks!

Code:

function _do_upload($file) {
              $config['upload_path'] = '/Applications/MAMP/htdocs/buy-arab-scarves/images/_uploads/';
            $config['allowed_types'] = 'jpg|gif|jpeg|png';
            $config['max_size']    = '2000';
            $this->load->library('upload', $config);
              
            $field_name = "prod_img"; //see http://ellislab.com/codeigniter/user-guide/libraries/file_uploading.html
            if (!$this->upload->do_upload($field_name)) {
                $this->form_validation->set_message('_do_upload', $this->upload->display_errors());
                return FALSE;
            }    
            else {    
            
                //array with data from uploaded (not processed!) image
                $image_data = $this->upload->data();
            
                //process & resize image
                $config['source_image'] = $config['upload_path'].$_FILES['prod_img']['name'];
                $config['maintain_ratio'] = TRUE;
                $config['height'] = 200;
                $config['create_thumb'] = TRUE;
                
                $this->load->library('image_lib', $config);
                $this->image_lib->resize();
                
                if($this->image_lib->resize() !== TRUE) {
                    print $this->image_lib->display_errors();
                    exit;
                }
                              
            }
            
            return $image_data;
          }
