Yii - One to many update form - php

Question

I have a one to many relationship where a movie can have many youtubeclips.. Ive managed to create the models and display the movie data inside the update form. I now need to be able to create a loop of some sort to out put my many relationship data into the form.. But cant seem to figure out how to do it.. This is what I have so far..
MovieController --
public function actionUpdate($id)
{
$model=$this->loadModel($id);
$modelYoutubeVideo=$this->loadYoutubeVideoModel($id);
$modelTwitterFeed=$this->loadTwitterModel($id);
if(isset($_POST['Movie']))
{
$model->attributes=$_POST['Movie'];
if($model->save())
$this->redirect(array('view','id'=>$model->id));
}
$this->render('update',array(
'model'=>$model,
'modelYoutubeVideo'=>$modelYoutubeVideo,
'modelTwitterFeed'=> $modelTwitterFeed
));
}
Update Form --
<div class="row clone">
<?php echo $form->labelEx($modelYoutubeVideo,'embed_code'); ?>
<?php echo $form->textField($modelYoutubeVideo,'embed_code[]',array('size'=>50,'maxlength'=>50)); ?>
<?php echo $form->error($modelYoutubeVideo,'embed_code'); ?>
<?php echo $form->labelEx($modelYoutubeVideo,'description'); ?>
<?php echo $form->textField($modelYoutubeVideo,'description[]',array('size'=>50,'maxlength'=>250)); ?>
<?php echo $form->error($modelYoutubeVideo,'description'); ?>
</div>
<?php
$this->widget('ext.widgets.reCopy.ReCopyWidget', array(
'targetClass'=>'clone',
));
?>
Need to Create a loop which outputs my data from the many relations ship table --
<?php
for ($i = 0; $i < count($modelYoutubeVideo); ++$i) {
($modelYoutubeVideo->embed_code[i]);
($modelYoutubeVideo->embed_code[i]);
}
?>
Movie Relationships --
public function relations()
{
// NOTE: you may need to adjust the relation name and the related
// class name for the relations automatically generated below.
return array(
'competitions' => array(self::HAS_MANY, 'Competition', 'movie_id'),
'studio' => array(self::BELONGS_TO, 'Studio', 'studio_id'),
'country' => array(self::BELONGS_TO, 'Country', 'country_id'),
'movieRating' => array(self::BELONGS_TO, 'MovieRating', 'movie_rating_id'),
'mapPin' => array(self::BELONGS_TO, 'MapPin', 'map_pin_id'),
'twitterFeeds' => array(self::HAS_MANY, 'TwitterFeed', 'movie_id'),
'YoutubeVideo' => array(self::HAS_MANY, 'YoutubeVideo', 'movie_id'),
);
}

Answer 1

in your actionUpdate you can use use relation like this
$model=$this->loadModel($id);
$youTubevideos=$model->YoutubeVideo;
Here YouTubeVideo is the same relation name in your model.It will bring you all the youtubeVideo active records related to specific movie. Now pass this array to your view like
$this->render('update',array(
'model'=>$model,
'modelYoutubeVideo'=>$modelYoutubeVideo,
'modelTwitterFeed'=> $modelTwitterFeed,
'youTubeVideos'=>$youTubeVideos,
));
then in your view use foreach loop to show each value of the model like
foreach($youTubeVideos as $video)
{
echo $video->name;
}
In above echo statement actually you can echo any thing like CdetailView widget or anything you want repeatedly.
