Zend and mootools

Question

Hi There,

I am trying to write a commenting system with Zend and Mootools, basically mootools provides and modalbox and Zend processes the comment etc. My issue is that I cannot get the ID of the post that the user is commenting on to move from Javscript to PHP. I think it is because the Modal window is an iFrame essentially. Below is my code,

The Javascript

<a href="#" class="5" id="ymdOpener">Open Window</a> 
<script type="text/javascript">  
var id = $('ymdOpener').className;
var ymd = new yamoodow([
{ url:'/comments/index/id/'+id, text:'Iframe', iframe:true } ], 
{ opener:$('ymdOpener'), title: 'Yamodow-Demo' }); 

</script>

The Controller

public function indexAction(){
        //$this->_helper->layout->disableLayout();
        //$this->layout()->setLayout('commentLayout.phtml');
        if(isset($_POST['submit_comment'])) {
        //die("heere");
            $pfx = $this->tablePrefix;
            $comments = new JustMilk_Model_Comment('comments', $pfx, $this->db);
            if($comments->save($this->db))
            {
                $this->_redirect('/comments/success');
            }

        }

        $pms = $this->getRequest()->getParams();
        $vA = array(
            'id' => $pms['id'],
        );
        //var_dump($vA);
        $this->view->assign($vA);
    }

The View

<form action="" method="post">
<fieldset>
    <div class="segment">
        <div class="label">
            <label form="email_address">Email Address</label>
        </div>
        <div class="input">
            <input type="text" name="email_address" />
        </div>
    </div>
    <div class="segment">
        <div class="label">
            <label form="show_email">Publish Email</label>
        </div>
        <div class="input">
            <input type="checkbox" name="show_email" value="1" />
        </div>
    </div>
    <div class="segment">
        <div class="label">
            <label for="comments">Comments</label>
        </div>
        <div class="input">
            <textarea name="comments"></textarea>
        </div>
    </div>
    <input type="hidden" name="recipe_id" value="<?=$this->id;?>" />
    <div class="segment">
        <div class="input">
            <button class="submit" value="Submit form" type="submit" id="submit" name="submit_comment">Submit</button>
        </div>
    </div>
</fieldset>

Is there a reason when the ID (currently the class name of the <a>) is not getting passsed to the controller then onto the view?
