Hi all, im new to the Yii and Object oriented, I received an error when displaying the list view.Can u guys help me? Thanks.

Error:Fatal error: Call to a member function getAttributeLabel() on array in C:\xampp\htdocs\TESTING\protected\views\branch\_myview.php on line 3

Codes:

a)BranchController.php

public function actionshow($id)

{


	$branch_name=branch::model()->findByPk($id)->branch_name;





	$pageTitle = "Branch - $branch_name";


	


	


	$count=Yii::app()->db->createCommand('SELECT COUNT(*) FROM branch')->queryScalar();


	$sql = 'SELECT * FROM branch WHERE branch_name = "Kota Kinabalu"';


	$dataProvider=new CSqlDataProvider($sql,array(


		'keyField'=>'id',


		'totalItemCount'=>$count,


		'sort'=>array(


			'attributes'=>array('id'),


			'defaultOrder'=>array('id'=>false),


		),


		'pagination'=>array(


			'pageSize'=>10,


		),


	));


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


	'dataProvider'=>$dataProvider,


	'pageTitle'=>$pageTitle,));





}

b)myview.php

<?php

$this->breadcrumbs=array(‘branch’,);

?>

<?php

&#036;this-&gt;widget('zii.widgets.CListView',array(


	'dataProvider'=&gt;&#036;dataProvider,


	'itemView'=&gt;'_myview',


));

?>

c)_myview

<div class="myview">

&lt;b&gt;&lt;?php echo CHtml::encode(&#036;data-&gt;getAttributeLabel('id')); ?&gt;:&lt;/b&gt;


&lt;?php echo CHtml::encode(&#036;data-&gt;id); ?&gt;


&lt;br /&gt;

</div>

You are using a CSqlDataProvider, so you haven’t instances of your model, but only raw data.

So in _myview.php you must add an object from branch model to get all methods:




<?php $obj = new branch(); ?>


<div class="myview">


<b><?php echo CHtml::encode($obj->getAttributeLabel('id')); ?>:</b>

<?php echo CHtml::encode($data->id); ?>

<br />


</div>

Otherwise you can change CSqlDataProvider in ActiveDataProvider, so you should have an array of ActiveRecord, instead of an array of raw data.

Appreciate and thanks for the reply as i didnt receive any error anymore.Let say that I try this way,

I have a problem that It didnt show the value eventhough the return row is correct as I already double check.Could it be that the CSqlDataProvider didnt sent fully to the view?

FYI:I change the _myview.php:[/b]

<div class="myview">

<b><?php echo CHtml::encode($obj->getAttributeLabel(‘id’)); ?>:</b>

<?php echo CHtml::encode($obj->id); ?>

<br />

</div>

INTO:

<div class="myview">

<b><?php echo CHtml::encode($obj->getAttributeLabel(‘branch_name’)); ?>:</b>

<?php echo CHtml::encode($obj->branch_name); ?>

<br />

</div>

If you change into




<div class="myview">

<b><?php echo CHtml::encode($obj->getAttributeLabel('branch_name')); ?>:</b>

<?php echo CHtml::encode($obj->branch_name); ?>

<br />

</div>

obviously $obj is a fresh object, so it hasn’t any data.

In my example i’ve used for data to display $data object.

See again my example:




<?php $obj = new branch(); ?>


<div class="myview">


<b><?php echo CHtml::encode($obj->getAttributeLabel('id')); ?>:</b>

<?php echo CHtml::encode($data->id); ?>

<br />


</div>

Attribute label is form $obj, but data displayed is from $data.
