You can use Rename filter. If you want to rename your filename during uploading maybe it helps you.

First we need a function rename or remove unwanted characters from your filename for example use this.

public function simple_fileformat($str)
{
    $str = preg_replace("{[^A-Za-z0-9_]\.}", "", $str);
    $str = str_replace(" ", "_", $str);
    return $str;
}

After that you can use the above function for renaming.

$filename = new Zend_Form_Element_File("filename");
$filename->setLabel("filename");
$filename->setRequired(true);
$filename->setDestination($doc_path);
$filename->addFilter("rename", $doc_path . DIRECTORY_SEPARATOR . $this->simple_fileformat(basename($filename->getFileName())));

That is easy. Is not it?
