Large file upload with SWFUpload jQuery Plugin

Using Codeigniter 1.7.2 and "SWFUpload jQuery Plugin" , I can successfully upload small images to server.
When I upload a large file for example 50 mb , progressbar show uploading and SWFUpload show that upload have been completed but codeigniter generate "You did not select a file to upload" error that means "uploadfile" variable is empty.

Have any one can help to solve this problem.

This is my controller:
<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Ifuncupload extends Controller {
    function Ifuncupload() {
        $config['upload_path'] = getcwd().'\uploads';
        $config['allowed_types'] = 'jpg|png';
        $config['max_size']    = '1000000000'; //large size
        $config['max_width']  = '102400';
        $config['max_height']  = '76800';
        $this->load->library('upload', $config);
        $this->load->helper(array('form', 'url'));
      function index(){
    function do_upload() {
            $error = array('error' => $this->upload->display_errors());
            print_r ($error);
And my view:

        upload_url: "ifuncupload/do_upload",
        file_post_name: 'uploadfile',
        file_size_limit : 10000000000, //kb
        file_types : "*.jpg;*.png;*.gif",
        file_types_description : "Image files",
        file_upload_limit : 1,
        flash_url : "<?php echo base_url(); ?>testifunc/swfupload.swf",
        button_image_url : '<?php echo base_url(); ?>testifunc/wdp_buttons_upload_114x29.png',
        button_width : 114,
        button_height : 29,
        button_placeholder : $('#button')[0],
        debug: true
        .bind('fileQueued', function(event, file){
            var listitem='<li id="'+file.id+'" >'+
                'File: <em>'+file.name+'</em> ('+Math.round(file.size/1024)+' KB) <span class="progressvalue" ></span>'+
                '<div class="progressbar" ><div class="progress" ></div></div>'+
                '<p class="status" >Pending</p>'+
                '<span class="cancel" >&nbsp;</span>'+
            var swfu = $.swfupload.getInstance('#swfupload-control');
            $('li#'+file.id+' .cancel').bind('click', function(){
        .bind('fileQueueError', function(event, file, errorCode, message){
            alert('Size of the file '+file.name+' is greater than limit');
        .bind('fileDialogComplete', function(event, numFilesSelected, numFilesQueued){
            $('#queuestatus').text('Files Selected: '+numFilesSelected+' / Queued Files: '+numFilesQueued);
        .bind('uploadStart', function(event, file){
            $('#log li#'+file.id).find('p.status').text('Uploading...');
            $('#log li#'+file.id).find('span.progressvalue').text('0%');
            $('#log li#'+file.id).find('span.cancel').hide();
        .bind('uploadProgress', function(event, file, bytesLoaded){
            var percentage=Math.round((bytesLoaded/file.size)*100);
            $('#log li#'+file.id).find('div.progress').css('width', percentage+'%');
            $('#log li#'+file.id).find('span.progressvalue').text(percentage+'%');
        .bind('uploadSuccess', function(event, file, serverData){
            var item=$('#log li#'+file.id);
            item.find('div.progress').css('width', '100%');
            var pathtofile='<a href="uploads/'+file.name+'" target="_blank">view &raquo;</a>';
            item.addClass('success').find('p.status').html('Done!!! | '+pathtofile);
        .bind('uploadComplete', function(event, file){
        function para(s){
            s.addPostParam('test', $('#test').val());

Is php.ini set up to allow for big uploads?
e.g. upload_max_filesize and post_max_size?

Did you increase upload max file size for server? it can be changed in php.ini

I changed max size in php.ini:
upload_max_filesize = 80M
post_max_size = 80M
And now codeigniter doesn't send any error.
But I got another error:

SWF DEBUG: Event: uploadError : Upload limit reached. No more files can be uploaded.

I know the error is related to SWFUpload and I must slove it.

I'm getting this:
SWF DEBUG:     [error] => <p>The filetype you are attempting to upload is not allowed.</p>

This is the config
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size']    = '100';
$config['max_height']  = '768';

But the swf returns this
[uploadfile] => Array
SWF DEBUG:         (
SWF DEBUG:             [name] => buton_nou_cs.gif
SWF DEBUG:            [type] => application/octet-stream
SWF DEBUG:             [tmp_name] => /tmp/phpv5bEW7
SWF DEBUG:             [error] => 0
SWF DEBUG:             [size] => 48148
SWF DEBUG:         )

It always return [type] => application/octet-stream.

How did this work for you?

add 'application/octet-stream' to the mime types config file for image uploads ;-)
