Hi everybody,
I just have done the Yii Blog tutorial and now i want to show all the comments in the post/index.php (where you are able to see all posts in a list) which worked fine so far, but the thing that doesn’t work is commenting. Because the form doesn’t know the post id.
So my question is, how can I pass the post id to the postController? Or is there an even better solution?
Thanks a lot,

If you are displaying the post page, you should have a $model variable with the model.
Here you have all data of the post. Use a form with an action like:
'action'=>array('post/comment', 'id'=>$model->id)
And you will got in the action comment a $_GET variable with the id of the post.
Thanks for your help so far. But I couldn’t solve the problem yet.
The thing is, that i got a list of "posts" (I called them "entrys") shown on the page and each can be commented.
So my _view (entry) looks as follows:
<div class="view">
<?php echo CHtml::link(CHtml::encode($data->translations[0]->title), array('view', 'id' => $data->entry_id)); ?>,
<?php echo Yii::app()->locale->dateFormatter->formatDateTime($data->update_time, 'long', 'medium') ?>, von
<?php echo $data->user->username; ?>,
<?php if ($data->commentCount >= 1): ?>
<?php echo $data->commentCount . ' Kommentare'; ?>
<?php endif; ?>
<?php echo $data->translations[0]->content; ?>
<br />
<div id="comments">
<?php if (Yii::app()->user->hasFlash('commentSubmitted')): ?>
<div class="flash-success">
<?php echo Yii::app()->user->getFlash('commentSubmitted'); ?>
</div>
<?php else: ?>
<?php
$this->renderPartial('/comment/_form', array(
'model' => $data->comments,
'entry' => $data,
));
?>
<?php endif; ?>
<?php if ($data->commentCount >= 1): ?>
<?php
$this->renderPartial('_comments', array(
'entry' => $data,
'comments' => $data->comments,
'translation' => $data->comments->translations[0],
)); ?>
<?php endif; ?>
</div><!-- comments -->
</div>
The called _form (entry) looks like that:
<div class="form">
<?php
$form = $this->beginWidget('CActiveForm', array(
'id' => 'comment-form',
'enableAjaxValidation' => true,
));
?>
<?php echo $form->errorSummary($model); ?>
<div class="row">
<?php echo '<p style="font-size:18px; color:#000;">Wie sehen Sie das? </p>' ?>
<?php echo $form->textArea(Translation::model(), 'content', array('rows' => 1, 'cols' => 50)); ?>
<?php echo $form->error(Translation::model(), 'content'); ?>
</div>
<div class="row buttons">
<?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save'); ?>
</div>
<?php $this->endWidget(); ?>
</div><!-- form -->
And the _comments (entry) looks like that:
<?php foreach ($comments as $comment): ?>
<div class="comment" id="c<?php echo $comment->comment_id; ?>">
<div class="content">
<span>
<?php echo nl2br(CHtml::encode($comment->translations[0]->content)); ?>
</span>
</div>
<div class="author">
von <?php
if ($comment->user->username == null) {
echo $comment->authorLink;
} else {
echo $comment->user->username;
}
?>,
<?php echo Yii::app()->locale->dateFormatter->formatDateTime($comment->create_time, 'long', 'medium') ?>
</div>
<div class="time">
</div>
<br/>
</div><!-- comment -->
<?php endforeach; ?>
In the EntryController I thought of making the following call in the actionIndex Method:
$comment = $this->newComment($this->loadModel());
The newComment function needs an entry model object…
And now the newComment function in EntryController should receive the correct entry_id (belonging to the posted comment):
public function loadModel()
{
if ($this->_model === null) {
if (isset($_GET['id'])) {
if (Yii::app()->user->isGuest)
$condition = 'status=' . Entry::STATUS_PUBLISHED
. ' OR status=' . Entry::STATUS_ARCHIVED;
else
$condition='';
$this->_model = Entry::model()->with('translations')->findByPk($_GET['id'], $condition);
}
if ($this->_model === null)
throw new CHttpException(404, 'The requested page does not exist.');
}
return $this->_model;
}
Just cant figure out how to solve this … there must be an easy solution but i’ve now tried so much, that Im even more confused :-D. still learning Yii 
Thanks in advance,
