在yii中进行错误验证后，留在同一页面上

Question

I would like to avoid redirecting after error validation.

I display a list of post and for each post the user can give a comment after clicking on a button.

This display the comment form under the choosen post.

If there is an error in validation of the comment I want to stay on the page and display errors beside the field in error (as default).

Here is My controller action for the comment

public function actionCreate()
    {
        $model=new Comment;

        if(isset($_POST['Comment']))
        {
            $model->attributes=$_POST['Comment'];

            if($model->save()) {
                $this->redirect(Yii::app()->request->urlReferrer);

            } else {

                 Yii::app()->end();

            }
        }

        $this->render('create',array(
            'model'=>$model,
        ));
    }

and the view

<div class="form">

<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'comment-form',
    'enableClientValidation'=>true,
)); ?>

    <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,'comment'); ?>
        <?php echo $form->textField($model,'comment',array('size'=>60,'maxlength'=>140)); ?>
        <?php echo $form->error($model,'comment'); ?>
    </div>

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

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

</div><!-- form --> 

For the moment, with Yii::app()->end(); it shows a blank page, if I dont do nothing in the else part , then it continues and displays the create view (loosing some decoration)

---Adding some more information

Actually, what I have in my page is this

Post 1
(Comment form)
Commment  :   ........
Save

Post 2

Post 3

when I click on save without comment, I want to stay in this page, giving the user the possibility to see where the error is (comment is missing) and save it again.

Can you tell me where is my mistake?

Thank you for your help

Answer 1

in the else block you have to tell yii to render the same page again. After calling $model->save() you get errors back in the model. So before Yii::app()->end(); call rendering of your page $this->render('create',array('model'=>$model,));
