问：如何将过滤后的数据从cgridview打印到csv？
状态：我遵循here的指示。但现在我得到了飞机csv（excel）文件。没有标题，没有数据。
这是观点
<?php
echo CHtml::button('Export', array('id'=>'export-button','class'=>'span-3 button'));
?>
<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'request-grid',
'dataProvider'=>$model->creator(),
'filter'=>$model,
'columns'=>array(
'request_no',
array(
'name'=>'request_type_id',
'value'=>'$data->requesttypes->name',
),
array(
'name'=>'request_category_id',
'value'=>'$data->requestcategories->name',
),
array(
'name'=>'financial_type_id',
'value'=>'$data->requestfinanicaltypes->name',
),
array(
'name'=>'urgency_id',
'value'=>'$data->requesturgent->name',
),
'status',
'eta_date',
'completed_date',
'created_date',
array(
'class'=>'CButtonColumn',
'template'=>'{update}{view}{copy}',
'buttons'=>array(
'delete'=>array(
'visible'=>'true',
'options'=>array('style'=>'align:left;'),
),
'view'=>array(
'visible'=>'true',
'options'=>array('style'=>'align:left;'),
),
'update'=>array(
'visible'=>'$data->status == \'Pending\'',
),
'copy'=>array(
'imageUrl'=>Yii::app()->request->baseUrl.'/images/assets/Copy2.png',
'url'=>'Yii::app()->createUrl("creator/copy", array("id"=>$data->id))',
'options'=>array('style'=>'border:none;'),
),
),
'htmlOptions'=>array(
'style'=>'text-align: right; padding-right:3px;'
),
),
),
)); ?>
<?php
Yii::app()->clientScript->registerScript('delete-item', "
$('#export-button').on('click',function() {
$.fn.yiiGridView.export();
});
$.fn.yiiGridView.export = function() {
$.fn.yiiGridView.update('request-grid',{
success: function() {
$('#request-grid').removeClass('grid-view-loading');
window.location = '". $this->createUrl('exportFile') . "';
},
data: 'export=true'
});
}
");
?>
这是我的控制器
public function actionExport()
{
$fp = fopen('php://temp', 'w');
/*
* Write a header of csv file
*/
$headers = array(
'request_no',
'status',
'eta_date',
'completed_date',
'created_date',
);
$row = array();
foreach($headers as $header) {
$row[] = Request::model()->getAttributeLabel($header);
}
fputcsv($fp,$row);
/*
* Init dataProvider for first page
*/
$model=new Request('Creator');
$model->unsetAttributes(); // clear any default values
if(isset($_GET['Request'])) {
$model->attributes=$_GET['Request'];
}
$dp = $model->search();
/*
* Get models, write to a file, then change page and re-init DataProvider
* with next page and repeat writing again
*/
while($models = $dp->getData()) {
foreach($models as $model) {
$row = array();
foreach($headers as $head) {
$row[] = CHtml::value($model,$head);
}
fputcsv($fp,$row);
}
unset($model,$dp,$pg);
$model=new Request('Creator');
$model->unsetAttributes(); // clear any default values
if(isset($_GET['Request']))
$model->attributes=$_GET['Request'];
$dp = $model->search();
$nextPage = $dp->getPagination()->getCurrentPage()+1;
$dp->getPagination()->setCurrentPage($nextPage);
}
/*
* save csv content to a Session
*/
rewind($fp);
Yii::app()->getRequest()->sendFile('aa.csv', stream_get_contents($fp), "text/csv", false);
//Yii::app()->user->setState('export',stream_get_contents($fp));
fclose($fp);
}
public function actionExportFile()
{
Yii::app()->request->sendFile('export.csv',Yii::app()->user->getState('export'));
Yii::app()->user->clearState('export');
}
我哪里错了？
========================更新
现在我正在堆叠以导出关系数据，并且一些字段由csv和jason保存数据。我不知道在报告中导出这些数据。请帮我。
这是我的模特

这是我的控制器
public function actionExcel() {

$xls = new JPhpExcel('UTF-8', false, 'test');

这是模型（aaa.php）

Yii::import('application.extensions.phpexcel.JPhpExcel');
$xls = new JPhpExcel('UTF-8', false, 'test');

}
这是我使用的phpexcel。 （不是来自他们网站的完整的phpexcel lib。）
在views / aaa / index.php中调用？r = aaa / excel，这将导出当前过滤的数据或第一页数据。
