Assigning tags to a post from front end using tag-it jquery UI plugin

I added the fieldName parameter to tagit function like this:

<script type="text/javascript">
    $(document).ready(function() {
        $("#myTags").tagit(
        {
        fieldName: "tages[]"
        }
        );
    });
</script>

Now I can echo $_POST['tages']; since the HTML after execution became:

<input type="hidden" style="display:none;" value="d" name="tages">

In addition, $_POST['tages']; is a PHP array which I can directly put in second parameter of wp_set_object_terms.

Thank you very much, some problems take a lot of time to resolve, but only before posting them on SE.
