Tabular Input For Nestedsetbehavior Extension

Tabular Input on nestedsetbehavior

How could it be done?

as example from yii documentation


public function actionBatchUpdate()

{

    // retrieve items to be updated in a batch mode

    // assuming each item is of model class 'Item'

    $items=$this->getItemsToUpdate();

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

    {

        $valid=true;

        foreach($items as $i=>$item)

        {

            if(isset($_POST['Item'][$i]))

                $item->attributes=$_POST['Item'][$i];

            $valid=$item->validate() && $valid;

        }

        if($valid)  // all items are valid

            // ...do something here

    }

    // displays the view to collect tabular input

    $this->render('batchUpdate',array('items'=>$items));

}

this


$items=$this->getItemsToUpdate();

is placeholder for getting all data that you need for updating

i can change it to


$items=Nestedset::model()->findAll()

am i right?

but when using the nestedsetbehavior, if i want to get the whole tree

im querying


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

then




Category::model()->findAll(array('condition'=>'root=$roots','order'=>'lft');

How to make it become like this


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

I’m just stuck, or could you give me some logic how to do this?

thanks
