想在布局里放一个loginForm,这样的写法是否规范??? [ 新手入门 ]

我的做法是把控制器里的代码和视图里的代码全移到了视图中,效果是正确的,不知道是否规范?

<div class="form">
<?php 
$form=$this->beginWidget('CActiveForm', array(
    'id'=>'login-form',
    'enableClientValidation'=>true,
    'clientOptions'=>array(
        'validateOnSubmit'=>true,
    ),
)); 
?>

<?php
$model=new LoginForm;
// if it is ajax validation request
if(isset($_POST['ajax']) && $_POST['ajax']==='login-form') {
    echo CActiveForm::validate($model);
    Yii::app()->end();
}

// collect user input data
if(isset($_POST['LoginForm'])){
    $model->attributes=$_POST['LoginForm'];
    // validate user input and redirect to the previous page if valid
if($model->validate() && $model->login())
    $this->redirect(Yii::app()->user->returnUrl);
}
?>
<div class="row">
    <?php echo $form->labelEx($model,'用 户:'); ?>
    <?php echo $form->textField($model,'username',array('class'=>'text')); ?>
    <?php echo $form->error($model,'username'); ?>
</div>

<div class="row">
    <?php echo $form->labelEx($model,'密 码: '); ?>
    <?php echo $form->passwordField($model,'password',array('class'=>'text')); ?>
    <?php echo $form->error($model,'password'); ?>
</div>

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

<div class="row buttons">
    <?php echo CHtml::submitButton('登 录',array('class'=>'button')); ?>
    <?php echo CHtml::Button('注 册',array('class'=>'button')); ?>
</div>

<?php $this->endWidget(); ?>
</div><!-- form -->
