Using SWFUpload + Sessions + upload class, how I did it.

Code:

$user_id = $this->uri->segment(3);

    //print('User ID:'.$user_id);

    $upload_name = 'Filedata';

    //print_r($_FILES);

    //echo $count;

    //log_message('info', 'Just inside loop');

        $fileName = $_FILES[$upload_name]['name'];

        //echo 'Name is: ' . $fileName . '<BR>';

        //log_message('info', $this->dx_auth->get_user_id());

        $file = array(

        'name' => addslashes($fileName),

        'type' => $_FILES[$upload_name]['type'],

        'size' => $_FILES[$upload_name]['size'],

        'user_id' => $user_id);

        $tmpName  = $_FILES[$upload_name]['tmp_name'];

        $content = read_file($tmpName);

        $content = addslashes($content);

        $file['content'] = $content;

        $this->db->insert('files', $file);

Code:

var swfu;



        window.onload = function() {

            var settings = {

                flash_url : "&lt;?=$url?&gt;flash/swfupload.swf",

                upload_url: "&lt;?=$site_url?&gt;/manage/do_upload/&lt;?=$this->dx_auth->get_user_id()?&gt;",    // Relative to the SWF file

                post_params: {"PHPSESSID" : "&lt;?=$this->session->userdata('session_id')?&gt;"},

                file_size_limit : "100 MB",

                file_types : "*.pdf",

                file_types_description : "Only PDF",

                file_upload_limit : 100,

                file_queue_limit : 0,

                custom_settings : {

                    progressTarget : "fsUploadProgress",

                    cancelButtonId : "btnCancel"

                },

                debug: false,



                // Button settings

                button_image_url: "&lt;?=$url?&gt;images/TestImageNoText_65x29.png",    // Relative to the Flash file

                button_width: "65",

                button_height: "29",

                button_placeholder_id: "spanButtonPlaceHolder",

                button_text: '<span class="theFont">Browse</span>',

                button_text_style: ".theFont { font-size: 16; }",

                button_text_left_padding: 6,

                button_text_top_padding: 3,

                

                // The event handler functions are defined in handlers.js

                file_queued_handler : fileQueued,

                file_queue_error_handler : fileQueueError,

                file_dialog_complete_handler : fileDialogComplete,

                upload_start_handler : uploadStart,

                upload_progress_handler : uploadProgress,

                upload_error_handler : uploadError,

                upload_success_handler : uploadSuccess,

                upload_complete_handler : uploadComplete,

                queue_complete_handler : queueComplete    // Queue plugin event

            };



            swfu = new SWFUpload(settings);

         };

Code:

&lt;?php

class Files extends Controller {



    function files() 

    {

        parent::Controller();

        

        $this->load->library('DX_Auth');

        $this->load->orm('file');

        $this->load->helper('form');

        

        // Ensure user is logged in

        if (!$this->dx_auth->is_logged_in())  

        {  

            // Redirect to login page

            redirect('/auth/login/', 'refresh');

        } 

    }
