Yii CForm，嵌套表单 Ajax 验证

Question

我创建了以下嵌套表单数组；

return array(

    'elements' => array(
        'contact' => array(
            'type' => 'form',
            'elements' => array(
                'first_name' => array(
                    'type' => 'text',
                ),
                'last_name' => array(
                    'type' => 'text',
                )
            ),
        ),
        'lead' => array(
            'type' => 'form',
            'elements' => array(
                'primary_skills' => array(
                    'type' => 'textarea',
                ),
            ),
        ),
    ),

    'buttons' => array(
        'save-lead' => array(
            'type' => 'submit',
            'label' => 'Create',
            'class' => 'btn'
        ),
    )
);

我有这样的查看页面

echo $form->renderBegin();
echo $form['lead'];
echo $form['contact'];
echo $form->buttons['save-lead']; 
echo $form->renderEnd();

我的 actionCreate 是这样的

$form = new CForm('application.views.leads.register');
$form['lead']->model = new Lead;
$form['contact']->model = new Contact;

// how can i perform ajax validation only for $form['contact']
$this->performAjaxValidation($model); 

//if contact form save btn is clicked
if ($form->submitted('save-lead') && $form['contact']->validate() &&

    $form['lead']->validate()
) {

    $contact = $form['contact']->model;
    $lead = $form['lead']->model;
    if ($contact->save()) {
        $lead->contact_id = $contact->id;
        if ($lead->save()) {
            $this->redirect(array('leads/view', 'id' => $lead->id));
        }
    }
}

ajax验证方法是

protected function performAjaxValidation($model)
{
    if (isset($_POST['ajax']) && $_POST['ajax'] === 'contact') {
        echo CActiveForm::validate($model);
        Yii::app()->end();
    }
}

所以我的问题是如何分别对 $form['contact'] 和 $form['lead'] 元素执行 ajax 验证？

Answer 1

一个页面中可以有多个表单，但它们不应嵌套。
嵌套表单无效。
