create separate pdf files in yii

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

        $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)){

        shell_exec("gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=/tmp/$filename_invoice /tmp/$filename_invoice /tmp/$filename_detail");
        echo "gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=/tmp/$filename_invoice /tmp/$filename_invoice /tmp/$filename_detail";

        exit();
            /*
        // ... or send to client as file download
        if(!$pdf->send($filename_invoice)){
            throw new Exception('Could not create PDF: '.$pdf->getError());
        }

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!?
