Yii - How to display display captcha in CPortlet? - yii

Question

I'm using portlet to display contact form - the very same as is on static page which comes generated as standard. I'm using the same ContactForm model. The form displays but captcha is not displaying and reports "CCaptchaValidator.action "captcha" is invalid. Unable to find such an action in the current controller."
I'm new to yii so it takes awfully lot of time to figure everything out. Any quick advice what I shell do to make it working?
Best!
Yii::import('zii.widgets.CPortlet');
class ContactFormCard extends CPortlet
{
public $title='Contact';
protected function renderContent()
{
$model=new ContactForm;
if(isset($_POST['ContactForm']))
{
$model->attributes=$_POST['ContactForm'];
if($model->validate())
$this->controller->refresh();
}
$this->render('contactFormCard',array('model'=>$model));
}
public function actions()
{
return array(
'captcha'=>array(
'class'=>'CCaptchaAction',
'backColor'=>0xFFFFFF,
),
);
}
}
and in portlet view:
<?php if(CCaptcha::checkRequirements()): ?>
<div class="row">
<?php echo $form->labelEx($model,'verifyCode'); ?>
<div>
<?php $this->widget('CCaptcha'); ?>
<?php echo $form->textField($model,'verifyCode'); ?>
</div>
<div class="hint">Please enter the letters as they are shown in the image above.
<br/>Letters are not case-sensitive.</div>
<?php echo $form->error($model,'verifyCode'); ?>
</div>
<?php endif; ?>

In you SiteController.php add:
public function actions() {
return array(
'captcha' => array(
'class' => 'CCaptchaAction',
'backColor' => 0xFFFFFF,
),
// [...]
);
}
In you ContactForm.php add:
public function rules() {
return array(
// [...]
array('verifyCode', 'captcha', 'allowEmpty' => !CCaptcha::checkRequirements(), 'message' => Yii::t('formsErros', 'Código de verificação incorreto.')),
// [...]
);
}
In you view.php
<!-- [...] -->
<?php if(CCaptcha::checkRequirements()): ?>
<div class="captcha">
<?=$form->labelEx($contactFormModel, 'verifyCode')?>
<?php $this->widget('CCaptcha', array('clickableImage' => true, 'showRefreshButton' => true, 'imageOptions' => array('id' => 'captchaContactForm', 'class' => 'clickableCursor'), 'buttonLabel' => '')); ?>
<?=$form->textField($contactFormModel, 'verifyCode', array('class' => 'verticalAlignBottom'))?>
<?=$form->error($contactFormModel, 'verifyCode')?>
</div>
<?php endif; ?>
