yii cgridview export into excel not working on pagination - excel

Question

my code export into excel works fine, 1 to 10 rows export if I filters rows that my code export filtered rows as my criteria. If I click to next page e.g 11 to 20 and then click on export button, export only first page 1 to 10 rows.
in my admin view export button code:
<div id='menub'><?php $this->widget('zii.widgets.CMenu', array(
'encodeLabel'=>false,
'htmlOptions'=>array(
'class'=>'actions'),
'items'=>array(
array(
'label'=>'<img align="absmiddle" alt = "'.Yii::t('internationalization','Export'). '" src = "'.Yii::app()->request->baseUrl.'/images/export.jpg" />',
//'label'=>'Export',
'url'=>array('expenses/excel'),
),
),
));
above link call to excel method in expenses controller.
code in my controller:
public function actionExcel() {
$issueDataProvider = $_SESSION['report-excel'];
$i = 0;
$data = array();
//fix column header.
//Could have used something like this - $data[]=array_keys($issueDataProvider->data[0]->attributes);.
//But that would return all attributes which i do not want
//$data[]=array_keys($issueDataProvider->data[0]->attributes);
$data[$i]['expenses_type_id'] = 'Type';
$data[$i]['amount'] = 'Amount';
$data[$i]['exp_date'] = 'Date';
$data[$i]['description'] = 'Description';
$i++;
//populate data array with the required data elements
foreach($issueDataProvider->data as $issue)
{
$data[$i]['expenses_type_id'] = $issue->expensesType->name;
$data[$i]['amount'] = $issue['amount'];
$data[$i]['exp_date'] = $issue['exp_date'];
$data[$i]['description'] = $issue['description'];
$i++;
}
Yii::import('application.extensions.phpexcel.JPhpExcel');
$xls = new JPhpExcel('UTF-8', false, 'test');
$xls->addArray($data);
$xls->generateXML('test_file');
}
I save data in
$_SESSION['report-excel']
and in my Model:
public function getSearchCriteria()
{
$criteria=new CDbCriteria;
if(!empty($this->from_date) && empty($this->to_date))
{
$criteria->condition = "exp_date >= '$this->from_date'"; // date is database date column field
}elseif(!empty($this->to_date) && empty($this->from_date))
{
$criteria->condition = "exp_date <= '$this->to_date'";
}elseif(!empty($this->to_date) && !empty($this->from_date))
{
$criteria->condition = "exp_date >= '$this->from_date' and exp_date <= '$this->to_date'";
}
$criteria->with = 'expensesType';
$criteria->join = 'LEFT JOIN expenses_type p ON t.expenses_type_id = p.id';
//s$criteria->compare('id',$this->id,true);
$criteria->compare('p.name',$this->expenses_type_id,true);
$criteria->compare('amount',$this->amount,true);
$criteria->compare('exp_date',$this->exp_date,true);
$criteria->compare('description',$this->description,true);
$criteria->order ='exp_date DESC';
return $criteria;
}
public function search()
{
// #todo Please modify the following code to remove attributes that should not be searched.
$data = new CActiveDataProvider(get_class($this), array(
'pagination'=>array('pageSize'=> Yii::app()->user->getState('pageSize',
Yii::app()->params['defaultPageSize']),),
'criteria'=>$this->getSearchCriteria(),
));
$_SESSION['report-excel']=$data;
return new CActiveDataProvider(get_class($this), array(
'criteria'=>$this->getSearchCriteria(),
));
every thing is works fine but on pagination.
kindly help.

Answer 1

CActiveDataProvider holds a set of items(all).So when you call actionExcel() the $page param is lost. So when you do actionAdmin() in your controller or search() in your model save your $_GET['page'] to an other session value. then set it when you do actionExcel().
$_GET['page'] = $_SESSION['your_session_page_value'];
Hope this helps
