Yii CGridView update

Question

So I gave up on all of the above and decided to move the colums I wanted to show with ajax in a different grid in the main grid but for some reason i get this error:

Trying to get property of non-object

/var/www/html/framework/base/CComponent.php(607) : eval()'d code(1)

<?php
$this->breadcrumbs=array(
        'Fund Admin'=>array('/FundAdmin/index/'),
    'Contract Notes'=>array('index'),
    'List',
);

$user = Yii::app()->user;

$this->menu=array(
        array('label'=>'Fund Prices', 'url'=>array('/FundPrice/index'), 'visible'=>$user->checkAccess('listFPrice')),
        array('label'=>'Reports','url'=>array('/FundAdmin/index'), 'visible'=>$user->checkAccess('listReports')),
    array('label'=>'Create Contract Note', 'url'=>array('create'), 'visible'=>$user->checkAccess('createCNote')),
    array('label'=>'Audit Contract Note', 'url'=>array('auditList'), 'visible'=>$user->checkAccess('auditListClient')),
    //array('label'=>'Audit Contract Note Item', 'url'=>array('/ContractNoteItem/auditList'), 'visible'=>$user->checkAccess('auditListClient')),
);

Yii::app()->clientScript->registerScript('search', "
$('.search-button').click(function(){
    $('.search-form').toggle();
    return false;
});
$('.search-form form').submit(function(){
    $.fn.yiiGridView.update('contract-note-grid',{
        data: $(this).serialize()
    });
    return false;
});
");
?>



<h1>List Contract Note</h1>

<p>
You may optionally enter a comparison operator (<b>&lt;</b>, <b>&lt;=</b>, <b>&gt;</b>, <b>&gt;=</b>, <b>&lt;&gt;</b>
or <b>=</b>) at the beginning of each of your search values to specify how the comparison should be done.

<?php echo CHtml::link('Advanced Search','#',array('class'=>'search-button')); ?>
<div class="search-form" style="display:none">
<?php $this->renderPartial('_search',array(
    'model'=>$model,
)); ?>
</div><!-- search-form -->

<?php 
//$data=NULL;
$this->widget('zii.widgets.grid.CGridView', array(
    'id'=>'contract-note-grid',
    'dataProvider'=>$model->search(),
    'filter'=>$model,
    'columns'=>array(           
                array(
                    'name'=>'cn_fund_house_id',
                    'type'=>'raw',
                    'value'=>'$data->cnFundHouse->fh_name',
                ),
                array(
                    'name'=>'contractNoteItems.cni_fund_id',
                    'type'=>'raw',
                    'value'=>'$data->contractNoteItems->f_name', 
        ),
                array(
                    'name'=>'contractNoteItems.cni_isin',
                    'type'=>'raw',
                    'value'=>'$data->contractNoteItems->cni_isin',
                ),

                array(
                    'name'=>'contractNoteItems.cni_client_account_no',
                    'type'=>'raw',
                    'value'=>'$data->contractNoteItems->cni_client_account_no',
                ),

        'cn_investment_date',
        //'cn_settlement_date',

        array(
            'class'=>'CButtonColumn',
                        'deleteConfirmation'=>'Are you sure you want to retire this item?
This item needs to be audited for retirement to take effect.',
            'template'=>'{view}{update}{delete}',
            'buttons'=>array(
                                'view' => array
                (
                                    'label'=>'view',
                                    'url'=>'Yii::app()->controller->createUrl("contractNoteItem/view",array("id"=>$data->getCNIid($data->id)))',
                                    'visible'=>"Yii::app()->user->checkAccess('editFund')",
                ),
                'update' => array
                (
                                    'label'=>'edit',
                                    'url'=>'Yii::app()->controller->createUrl("edit",array("id"=>$data["id"]))',
                                    'visible'=>"Yii::app()->user->checkAccess('editFund')",
                ),
                'delete' => array
                (
                                    'label'=>'retire',
                                    'url'=>'Yii::app()->controller->createUrl("retire",array("id"=>$data["id"]))',
                                    'visible'=>'$data->checkIfRetired($data["id"])',
                )
            )
        ),
    ),
)); 
?>

And the particular error comes to the )); right before the php closing tag so I do not understand. If I comment the 'value' for each of the arrays except the first one and the CButtonColumn arrays I don't get the error because I just don't populate the fields with data. So I don't really get why it does this because everything in the models are defined right.

Also note that when I upload the file to my live server I do not get the error but the colums does not show for these colums:

array(
                'name'=>'contractNoteItems.cni_fund_id',
                'type'=>'raw',
                'value'=>'$data->contractNoteItems->f_name', 
                 ),
        array(
            'name'=>'contractNoteItems.cni_isin',
            'type'=>'raw',
            'value'=>'$data->contractNoteItems->cni_isin',
        ),

        array(
            'name'=>'contractNoteItems.cni_client_account_no',
            'type'=>'raw',
            'value'=>'$data->contractNoteItems->cni_client_account_no',
        ),

The live server php is 5.3.27 and on my local server is 5.3.3 so I do not know why I get the error on the local. Anyway my question is about the data there not showing and giving me the error on the local server.

Answer 1

The value elements for your columns are the problem. When the value element of a column is not specified, Yii checks whether the object exists before getting the value of the desired attribute. Your value elements do not have this check hence the error.

For simplicity in your code, there is no need to add the value and type elements for some columns. As such your code becomes

'columns'=>array(
    ...
    'contractNoteItems.cni_fund_id',
    'contractNoteItems.cni_isin',
    'contractNoteItems.cni_client_account_no',
    ...
)

For more information, see CGridView.columns

Answer 2

I think you issues is in your button area you have lines like this:

'visible'=>'$data->checkIfRetired($data["id"])',

However $data should be an object not an array. Try changing it to:

'visible'=>'$data->checkIfRetired($data->id)',

In reality though you should need to pass any data to functions like checkIfRetired since it is already an instance. In the function you should just be able to use the value $this->id instead of having to pass it.
