magento中是否有任何服务器端表单验证？我已经创建了一个From和使用Magentos表单验证但如果有人禁用 javascipt并输入可能有害的内容,它将无法工作.如果没有内置类.有人可以指点我如何实现服务器端表单验证作为备份.这是我的表格代码

<div style="border:0px solid red; margin:0px auto;">

<?PHP $_PRoduct = $this->getProduct(); ?>


<form id="test" action="<?PHP echo Mage::getUrl('pricenotify/pricenotify/db') ?>" method="post">

            <label for="price">Price *</label>
            <input tyPE="text" id="price" name="price" value="" class="required-entry validate-number"/><br />
            <label for="email">Email Address *</label>
            <input type="text" id="email" name="email" value="" class="required-entry validate-email"/>
            <input type="hidden" id="id" name="id" value="<?PHP echo $_product->getId() ?>" />
            <input type="hidden" id="propri" name="propri" value="<?PHP echo $_product->getPrice() ?>" />

            <input type="submIT" name="submit" value="<?PHP echo $this->__('Submit') ?>" onclick="if(customForm.validator && customForm.validator.validate()) this.form.request(); return false;" />

</form>

<script type="text/javascript">
//< ![CDATA[
VAR customForm = new VarienForm('test',false);
//]]>
</script>

try {
            $postObject = new Varien_Object();
            $postObject->setData($post);

            $error = false;

            if (!Zend_Validate::is($postObject->getPrice(),'NotEmpty')) {
                $error = true;
            }

            if (!Zend_Validate::is($postObject->getEmail(),'EmailAddress')) {
                $error = true;
            }

            if ($error) {
                throw new Exception();
            }


            //save to db

            return;
        } catch (Exception $e) {
            Mage::getSingleton('customer/session')->addError(Mage::helper('pricenotify')->__('Unable to submit your request. Please,try again later'));
            $this->_redirect('/');

            return;
        }
