activeDropDownList form database

Hi,

An equivalent topic already exists, but I can’t find a solution.

I’m still playing with the blog demo and, as every blog, I would like to add categories. So, I want to add an [font=“Courier New”]activeDropDownList[/font] to the [font=“Courier New”]Post[/font] create view. And it doesn’t work.

I just added few lines to the actionCreate method :


public function actionCreate()

	{

		$post=new Post;

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

		{

			$post->attributes=$_POST['Post'];

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

				$post->validate();

			else if(isset($_POST['submitPost']) && $post->save())

				$this->redirect(array('show','id'=>$post->id));

		}

    $categories=Category::model()->findAll();

		$this->render('create',array(

      'post'=>$post, 

      'categories'=>$categories,

    ));

	}

In the view :


<?php echo CHtml::activeDropDownList($post, 'category', 

  CHtml::listData(

    $categories,

    'id',

    'name'

)); ?>

And I get :


PHP Error

It seems simple, where’s the error?

Kind regards,

Please refer stack. It says that in 6th line of view \views\post\create.php you are calling renderPartial.

Probably you missed pass there $categories into partial view. This renderPartial call should look something similar to following line of code




   $this->renderPartial( '_form',array('categories'=>$categories,'post'=>$post));

P.S. Just remember, that when you are using renderPartial, data passed into "parent" view are not automatically enabled in "child" view (here, called by renderPartial).

#?*&#?! you’re right… I totally forgot to check this part. Still learning, still learning.

Thanks a lot.
