Yii CActiveDataProvider with class argument? - php

Question

I found this code at this website. What would have to be in the $dp dataprovider for the class TotalColumn to be called in the CGridView? Do I have to have the class TotalColumn be somewhere in $dp? Any idea how I would declare that CActiveDataProvider?
<?php
// protected/views/inventory/index.php
Yii::import('zii.widgets.grid.CGridColumn');
class TotalColumn extends CGridColumn {
private $_total = 0;
public function renderDataCellContent($row, $data) { // $row number is ignored
$this->_total += $data->quantity;
echo $this->_total;
}
}
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider' => $dp, // provided by the controller
'columns' => array(
'id',
'name',
'quantity',
array(
'header' => 'Total',
'class' => 'TotalColumn'
)
)));
Here is my code, but nothing in my custom column is displayed:
Yii::import('zii.widgets.grid.CGridColumn');
class TotalSkills extends CGridColumn
{
private $test = "blah";
public function renderSkills($row, $data)
{
echo $this->test;
}
}
// People
echo CHtml::label('People', 'yw0', $shared_html_options);
$dataProvider = new CActiveDataProvider('Person');
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider'=>$dataProvider,
'columns'=>array(
'name',
'age',
array(
'header'=>'Total Skills',
'class'=>'TotalSkills'
)
)
));

Answer 1

You should create the TotalColumn class inside your protected/components directory as a TotalColumn.php file. That way you can use it in many different view files, instead of the view file that is defined only. Yii will load it automatically then.
$dp should be a typical DataProvider class (more likely a CActiveDataProvider) that is defined in your controller and passed to your view. The DataProvider can be as easy as the CGridView documentation describes it.

Answer 2

public function renderDataCellContent($row, $data)
is defined method in gridview
but there is no method such as
public function renderSkills($row, $data)
in gridview
