Hi,

I am trying to make codeigniter upload multiple files at once but all i get is errors. My code is this:

Code:

function do_upload()
    {
        // set upload set id
        $set_id = md5(rand(1, 7) . rand(1, 4) . rand(1, 6));
        
        // check to make sure upload form was posted
        if($this->input->post('task') == "doUpload")
        {
            // create upload directory
            if(!@mkdir($this->core->site_config['upload_path'] . $set_id . "/"))
            {
                // set flash message
                $this->session->set_flashdata('upload_error', 'Failed to create upload directory.');
                
                // redirect
                redirect($this->core->site_config['site_url'], 301);                
            }
            
            // if new upload directory exists add index.html file
            if(is_dir($this->core->site_config['upload_path'] . $set_id . "/"))
            {
                $fh = fopen($this->core->site_config['upload_path'] . $set_id . "/index.html", "w");
                fclose($fh);
            }
            
            // create the config for upload library
            $config['upload_path'] = $this->core->site_config['upload_path'] . $set_id . "/";
            $config['allowed_types'] = 'gif|jpg|png|bmp|jpeg';
            $config['max_size']  = $this->core->site_config['max_file_size']; // in KB
            $config['max_width']  = '0';
            $config['max_height']  = '0';
            
            // load the upload library
            $this->load->library('upload', $config);
            
            // create the config for image library
            $configThumb = array();
            $configThumb['image_library'] = 'gd2';
            $configThumb['source_image'] = '';
            $configThumb['create_thumb'] = TRUE;
            $configThumb['maintain_ratio'] = TRUE;
            $configThumb['width'] = 120;
            $configThumb['height'] = 120;
            
            // load the image library
            $this->load->library('image_lib');
            
            // loop over uploaded image files
            while(list($key, $value) = each($_FILES['image']['name']))
            {
                // handle the file upload
                $upload = $this->upload->do_upload($key);
                
                // file failed to upload - continue
                //if($upload === FALSE) continue;
                
                // get the data about the file
                $data = $this->upload->data();
                
                $uploadedFiles[$key] = $data;
                
                // if the file is an image - create a thumbnail
                if($data['is_image'] == 1)
                {
                    $configThumb['source_image'] = $data['full_path'];
                    $this->image_lib->initialize($configThumb);
                    $this->image_lib->resize();
                }  
                
                echo $this->upload->data();
                
                echo $this->upload->display_errors();
            }
                        
        }
    }

but all i get when upload is complete is:
