How to add class to Form in Yii framework?

Question

I have a form in Yii, and I want to add a class to the form :

<form class="subscribe_form" action="#" method="post">

I tried this but it's not working :

<?php $form=$this->beginWidget('CActiveForm', array(
                                                'class'=>'subscribe_form',
                        'id'=>'mail-list-addmail-form',
                        'enableAjaxValidation'=>false
                    )); ?>

Thanks for helping me!.

Solution

You need to pass an htmlOptions property, like this:

<?php $form=$this->beginWidget('CActiveForm', array(
                        'id'=>'mail-list-addmail-form',
                        'enableAjaxValidation'=>false,
                        'htmlOptions'=>array(
                          'class'=>'subscribe_form',
                        )
                    )); ?>
