Yii automatic generate report when data has been saved - php

Question

How do I get when it finishes inserting the data, perform direct application automatically generates reports based on the data that has just inputted ?
My controller (Save) :
public function actionCreate()
{
$model=new PurchaseOrder;
if(isset($_POST['PurchaseOrder']))
{
$model->attributes=$_POST['PurchaseOrder'];
if($model->save())
$this->redirect('index');
}
$this->render('create',array(
'model'=>$model,
));
}
My controller (Generate Report) :
public function actionCetak()
{
if(isset($_POST['PrintPO'])){
$data = $_POST['no_po'];
if($data==''){
return false;
}else{
$HTML2PDF = Yii::app()->ePdf->HTML2PDF();
$HTML2PDF->WriteHTML($this->renderPartial('data_print', array(
'data' => $this->loadCetak($data)
), true));
$HTML2PDF->Output();
}
}else{
$this->render('form_cetak_po');
}
}
both functions run smoothly, but when I combining into :
public function actionCreate()
{
$model=new PurchaseOrder;
if(isset($_POST['PurchaseOrder']))
{
$model->attributes=$_POST['PurchaseOrder'];
if($model->save())
$HTML2PDF = Yii::app()->ePdf->HTML2PDF();
$HTML2PDF->WriteHTML($this->renderPartial('data_print', array(
'data' => $this->loadCetak($model->id)
), true));
$HTML2PDF->Output();
$this->redirect('index');
}
$this->render('create',array(
'model'=>$model,
));
}
Application only do the insert function. How do I order when finished doing the insert, directly akang application and the data it generates can be downloaded.
Thanks

Answer 1

You misses brackets after if(save())
Look at this :
if(isset($_POST['PurchaseOrder']))
{
$model->attributes=$_POST['PurchaseOrder'];
if($model->save())
{ // <-- add this
$HTML2PDF = Yii::app()->ePdf->HTML2PDF();
$HTML2PDF->WriteHTML($this->renderPartial('data_print', array(
'data' => $this->loadCetak($data)
), true));
$HTML2PDF->Output();
} //<-- add this
else
{
$this->redirect('index');
}
}

Redirecting after download
I don't think this can be done.
The common thing in popular download sites is the reverse: first you go to the "after" page and then the download starts.
You can do this :
after save,redirect to something like this
index.php?r=controller/index&file_info=information
and in index method, check if ($_GET['file_info']), then create your pdf file and make the download.
