Blog tutorial: can't save comments

I’ve been following the blog tutorial and it is helping a lot to understand how Yii framework works.

Now I am at the Creating and displaying comments section of the tutorial and I can’t save comments.

In fact, I don’t get an error summary or any feedback at all if I miss required fields.

This my controller (it is named Robots instead of Post):

public function actionShow()


		$robots = $this->loadrobots();

		$robot_comment = $this->newComment($robots);

		$this->render('show', array('model'=>$robots, 'robots_comments'=>$robots->robots_comments, 'newComment' => $robot_comment));




	protected function newComment($robots)


		$robot_comment = new robots_comments;

		if (isset($_POST['robots_comments']))


			$robot_comment->attributes = $_POST['robots_comments'];

			$robot_comment->robot = $robots->id;

			$robot_comment->fecha = time();

			$robot_comment->status = robots_comments::STATUS_PENDING;


			if (isset($_POST['submitComment']) && $robot_comment->save())


				Yii::app()->user->setFlash('commentSubmited','Thank you');




		return $robot_comment;


This is the snippet that renders the comment form:

<?php $this->renderPartial('/robots_comments/_form',array(




)); ?>

This is the beginning of the comment form:

<?php if(Yii::app()->user->hasFlash('commentSubmitted')): ?>

<div class="form">

<?php echo Yii::app()->user->getFlash('commentSubmitted'); ?>


<?php return; endif; ?>

<div class="yiiForm">


Fields with <span class="required">*</span> are required.


<?php echo CHtml::beginForm(); ?>

<?php echo CHtml::errorSummary($comment); ?>

Any help will be greatly appreciated!

if there is no any feedback,means

if (isset($_POST['submitComment']) && $robot_comment->save())

does not work,check on $_POST[‘submitComment’] or $robot_comment->save(),make sure which one is false.

if the save() false,check the beforeValidate() method of the model,it should always return true. or check the beforeSave() method.

i had the same problem,qiang give the answer.

u can try it.good luck!

Thank you, thank you, thank you!!

I had a beforeSave that didn’t return true and was giving me that headache!

Now, the questions left are:

1- Why I don’t get the error message if I miss a required field?

2- If it is successful, why I don’t get the flash message?
