uploadify redirect after uploading all files

[eluser]jacobson[/eluser]
Hello, I have a problem with upladify. I managed to make it work properly. My question is how to check in my php code whether the uploading of all files is finished in order to redirect page (refresh to show the uploaded images)

Code:

function index($albumId) {
        if (!empty($_FILES)) {
            //$albumId = $this->uri->sement(2);
            $this->load->library('image_lib');
            
            $tempFile = $_FILES['Filedata']['tmp_name'];
            $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
            $targetFile = str_replace('//', '/', $targetPath) . $_FILES['Filedata']['name'];
            $fileName = $_FILES["Filedata"]["name"];

            move_uploaded_file($tempFile, $targetFile);
            
            echo str_replace($_SERVER['DOCUMENT_ROOT'], '', $targetFile);
            $maxId = 0;
            $q = $this->db->select('MAX(name) as maxid')->get('images');
            foreach($q->result() as $item)
                $maxId = $item->maxid;
          
            $maxId++;
            $newName = $maxId.'.jpg';
            
            $data = array(
                'albumId' => $this->uri->segment(3),
                'name' => $newName
            );

            $this->db->insert('images', $data);
            
            $config = array(
                'source_image' => APPPATH . '../images/uploads/tmp/' . $fileName,
                'new_image' => APPPATH . '../images/uploads/'. $newName,
                'maintain_ration' => TRUE,
                'width' => 500,
                'height' => 400
            );

            $this->image_lib->initialize($config);
            $this->image_lib->resize();
            $this->_create_thumbs($fileName, $newName);
            
            
            unlink(APPPATH . "../images/uploads/tmp/" . $fileName);
        }
    }

thx for help
