你需要使用Form Builder，它有大量的例子如何使用数组构造你的表单。它也支持子表单。只需按照链接教程中的例子操作即可，内容太长了，在这里无法引用。

更新日期：

class LoginForm extends CFormModel
{
    public $username;
    public $password;
}

$form = new LoginForm();
$form->validatorList->add(
    CValidator::createValidator('required', $form, 'username, password')
);

或者另一个例子：

class SomeModel
{
 public $orders;
 public function rules()
 {
  return array(
   array('orders', 'validateOrders'),
  );
 }

 public function validateOrders($attribute, $params)
 {
  foreach($this->orders as $order)
   if (empty($order)) {
    $this->addError('orders', 'There is an empty order');
    break;
   }
 }
}

一个more broader example is on forum。

I am trying to build this dynamic profile management let me know my approach is my approach is right?

firstly i have created a input form(_form) where user can input fieldtype,fieldname,fieldtitle and field default value and etc which can be save in database table (profile_fields).In this fieldtype is bydefault set and user choose it from dropdownlist As like in the below form.

<?php
/* @var $this ProfileManagerController */
/* @var $model ProfileFields */
/* @var $form CActiveForm */

?>

<div class="form">

<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'profile-fields-form',
    'enableAjaxValidation'=>false,
)); ?>

    <p class="note">Fields with <span class="required">*</span> are required.</p>
    <?php echo $form->errorSummary($model); ?>

    <div class="row">
        <?php echo $form->labelEx($model,'location'); ?>
        <?php echo $form->dropDownList($model,'location',CHtml::listData(Countries::model()->findAll('',array('orderby' => 'countryName ASC')),'countryCode','countryName'), array('empty' => array("*" => 'For All Countries'))); ?>
        <?php echo $form->error($model,'location'); ?>
    </div>
    <div class="row">
        <?php echo $form->labelEx($model,'profile_type'); ?>
        <?php echo $form->dropDownList($model,'profile_type',Yii::app()->params['userRoles'], array('empty' => array("*" => 'For All users')), array($model->profile_type)); ?>
        <?php //echo $form->dropDownList($model, 'profile_type', Yii::app()->params['userRoles'], array($model->profile_type)); ?>
        <?php echo $form->error($model,'profile_type'); ?>
    </div>
    <div class="row">
        <?php echo $form->labelEx($model,'section'); ?>
        <?php echo $form->dropDownList($model,'section',array('profile'=>'profileSection','basicdetails'=>'BasicDetails','contactdetails'=>'ContactDetails','imagedetails'=>'ImageDetails','clientdetails'=>'ClientDetails','tagdetails'=>'TagDetails','otherdetails'=>'OtherDetails','alldetails'=>'AllDetails')); ?>
        <?php echo $form->error($model,'section'); ?>
    </div>
    <div class="row">
        <?php echo $form->labelEx($model,'field_name'); ?>
        <?php echo $form->textField($model,'field_name',array('size'=>60,'maxlength'=>255)); ?>
        <?php echo $form->error($model,'field_name'); ?>
    </div>
    <div class="row">
        <?php echo $form->labelEx($model,'field_title'); ?>
        <?php echo $form->textField($model,'field_title',array('size'=>60,'maxlength'=>255)); ?>
        <?php echo $form->error($model,'field_title'); ?>
    </div>
    <div class="row">
        <?php echo $form->labelEx($model,'field_type'); ?>
        <?php echo $form->dropDownList($model,'field_type',array('text' => 'Text','date' => 'Date','email' => 'Email', 'radio' => 'Radio','multiselect' => 'Multi Select Dropdown List','file'=>'File','checkbox'=>'CheckBox','hidden'=>'Hidden','select'=>'Dropdownlist','password'=>'Password','checkboxlist'=>'Checkboxlist','radiolist'=>'Radiolist','textarea'=>'TextArea'),array('options' => array($model->field_type => array('selected' => true)))); ?>
        <?php echo $form->error($model,'field_type'); ?>
    </div>
    <div class="row">
        <?php echo $form->labelEx($model,'field_default_value'); ?>
        <?php echo $form->textArea($model,'field_default_value',array('rows'=>6, 'cols'=>50)); ?>
        <?php echo $form->error($model,'field_default_value'); ?>

        <?php echo $form->error($model,'required'); ?>
    </div>
    <div class="row">

          <?php echo $form->dropDownList($model, 'published', array('1' => 'Yes', '0' => 'No')); ?>
        <?php echo $form->error($model,'published'); ?>
    </div>
    <div class="row">

    </div>
    <div class="row buttons">
        <?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save'); ?>
    </div>

<?php $this->endWidget(); ?>

secondly I have created a view index file which will show dynamically what type of fieldstypes and fieldsname and field title are set by the user in profile_field table and call the extension created by me and then another  user can input accordingly .and these values are save in profile_field_values table .
