create separate pdf files in yii - php

Question

I am trying to create 2 separate pdf files with different content. I have the following code which creates the 2 files.
$invoice = Invoices::model()->findByPk($_GET['id']);
$invoicedetail = InvoicesDetail::model()->findAll(array("condition"=>"invoiceno=".$invoice->INVOICENO . " && biditems_id is null"));
$client = $invoice->pROJ->oRDERNO->addressesinvoices;
$invoices = Invoices::model()->findAll(array("condition"=>"PROJID=".$invoice->PROJID . " && INVOICENO != ".$invoice->INVOICENO));
/*$this->renderPartial("partialInvoice",
array(
"invoice"=>$invoice,
"client"=>$client,
//"lookupprocesstotalArr"=>$lookupprocesstotalArr,
"adjustments"=>$invoices,
"invoicedetail"=>$invoicedetail[0]
),true);
*/
$html = $this->renderPartial("partialInvoice",
array(
"invoice"=>$invoice,
"client"=>$client,
//"lookupprocesstotalArr"=>$lookupprocesstotalArr,
"adjustments"=>$invoices,
"invoicedetail"=>$invoicedetail[0]),true);
$filename_invoice = 'invoice_'.$invoice->INVOICENO.'.pdf';
Yii::import('application.extensions.pdfable.WkHtmlToPdf');
$pdf = new WkHtmlToPdf(array(
'no-outline', // Make Chrome not complain
'margin-top' => 10,
'margin-right' => 10,
'margin-bottom' => 10,
'margin-left' => 10,
));
$pdf->setOptions(array(
'orientation' => 'portrait'
));
// Add a HTML file, a HTML string or a page from a URL
$pdf->addPage($html);
// Save the PDF
$pdf->saveAs("/tmp/$filename_invoice");
// ... or send to client as file download
/*if(!$pdf->send($filename)){
throw new Exception('Could not create PDF: '.$pdf->getError());
}*/
$globalController = new GlobalController;
//$project = Projects::model()->findAll(array("condition"=>"PROJID=".$_GET['PROJID']));
//$projid = $_GET['PROJID'];
$pdfDetail = new WkHtmlToPdf();
$orientation = "Landscape";
$pdfDetail->setOptions(array('orientation'=>$orientation,
'no-outline', // Make Chrome not complain
'margin-right' => 10,
'margin-bottom' => 5,
'margin-left' => 10,
));
//$this->layout = 'pdf';
//get list of process stages for this project
$lastrun = $globalController->lastRun($invoice->PROJID);
$processstages = ExtHtml::listData($lastrun, 'ID',array('cumulative','ITEM'));
$lookupprocesstotalArr = $globalController->lookupprocesstotal($invoice->PROJID,$processstages);
// get all lines
$connection = Yii::app()->db;

exit();

The problem i have is the 1st pdf that gets created is overwritten by the content of the 2nd pdf which makes no sense.

Answer 1

I do not know the class you are using but this code seems suspicios:
-sOutputFile=/tmp/$filename_invoice /tmp/$filename_invoice /tmp/$filename_detail
For me it seems that you convert 2 files into 1 output files, so logically you overwrite it!?
