hi yii community,
i cant get the extension nestedsetbehavior to work.
What i want is to create a child node to a root node with calling category/create.
BUT when appendTo() method is called nothing happens.
I use yii v1.1.10 and this tutorial: http://www.yiiframework.com/extension/nestedsetbehavior/
model code
public function rules()
{
return array();
}
public function behaviors()
{
return array(
'nestedSetBehavior'=>array(
'class'=>'application.extensions.NestedSetBehavior.NestedSetBehavior',
'leftAttribute'=>'lft',
'rightAttribute'=>'rgt',
'levelAttribute'=>'level',
'hasManyRoots'=>false,
));
}
controller code:
public function actionIndex()
{
$model = Category::model();
$categories=$model->findAll('id<>'. 1);
$this->render('index',array(
'categories' => $categories,
));
}
public function actionCreate()
{
$model=new Category;
if(isset($_POST['Category']))
{
echo $_POST['Category']['id'] . '<br />';
echo $_POST['Category']['title'] . '<br />';
$root = Category::model()->findByPk(1);
$element=new Category;
$element->title=$_POST['Category']['title'];
$element->appendTo($root);
}
index view code:
<?php
$level=0;
foreach($categories as $n=>$category)
{
if($category->level==$level)
echo CHtml::closeTag('li')."\n";
else if($category->level>$level)
echo CHtml::openTag('ul')."\n";
else
{
echo CHtml::closeTag('li')."\n";
for($i=$level-$category->level;$i;$i--)
{
echo CHtml::closeTag('ul')."\n";
echo CHtml::closeTag('li')."\n";
}
}
echo CHtml::openTag('li');
echo CHtml::encode($category->title);
$level=$category->level;
}
for($i=$level;$i;$i--)
{
echo CHtml::closeTag('li')."\n";
echo CHtml::closeTag('ul')."\n";
}
echo CHtml::link('Root Element erstellen', CHtml::normalizeUrl(array('create')));
?>
_form view code:
<?php
$dataArr = array();
$combo_populate = Category::model()->findAll();
foreach($combo_populate as $comboVal)
{
array_push($dataArr, $comboVal['title']);
}
echo CHtml::label('Nach folgendem Element einfügen:','title');
$this->widget('ext.combobox.EJuiComboBox', array(
'model' => Category::model(),
'attribute' => 'id',
'data' => $dataArr,
'options' => array(
'onSelect' => '',
'onChange' => 'alert("changed value : " + $(this).val());',
'allowText' => true,
),
));
?>
<div class="row">
<?php echo $form->labelEx($model,'title'); ?>
<?php echo $form->textField($model,'title',array('size'=>60,'maxlength'=>100)); ?>
<?php echo $form->error($model,'title'); ?>
</div>
<div class="row buttons">
<?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save'); ?>
</div>
Is someone out there who can help me with this?
thanks in advance 
Edit: "appendTo" works now 
and if you want to delete a node: $element->deleteNode() …i dont know why the delete function isnt listed in tut?
