Dompdf not working

[eluser]bhakti.thakkar[/eluser]
Hello all,

there is a button on my page for creating a preview. when the user clicks the button, there is a prompt to either Open or Save the document. When a user clicks Save and then open the Saved document, it works well. But if directly clicks on open, then it generates :
<div style="border:1px solid #990000;padding-left:20px;margin:0 0 10px 0;">

<h4>A PHP Error was encountered</h4>

<p>Severity: Notice</p>
<p>Message: Undefined index: dompdfuniqueid</p>
<p>Filename: include/frame.cls.php</p>
<p>Line Number: 183</p>

to_pdf_pi.php

Code:

function pdf_create($html, $filename, $stream=TRUE)
{
    require_once("dompdf/dompdf_config.inc.php");
    
    $dompdf = new DOMPDF();
    $dompdf->load_html($html);
    $dompdf->render();
    if ($stream) {
        $dompdf->stream($filename.".pdf");
    } else {

         $output = $dompdf->output();
         file_put_contents('../../tmp/pdf/'.$filename.".pdf", $output);
//        write_file("./tmp/pdf/$filename.pdf", $dompdf->output());
    }
}

Controller : certificate.php

Code:

function PreviewCertificatePDF($TransactionCertificate_ID , $ITCType_TI) {
        
        $this->load->plugin('to_pdf');
        $data['TransactionCertificate_ID'] = $TransactionCertificate_ID;
        $query = $this->db->query("Exec up_parmsel_rpt_TempTransactionCertificate @TransactionCertificate_ID='$TransactionCertificate_ID' , @Company_ID='' ");
@TransactionCertificate_ID='$TransactionCertificate_ID' , @Company_ID='' ");
        $data['pgdata'] =$query->result_array();
    
             $pg="PreviewCertificate";
    
        $html = $this->load->view('certificates/'.$pg ,$data,true);


        $filename = 'TR'.$TransactionCertificate_ID."_".date('mYdHis');

        
        pdf_create($html, $filename,true);

}

The code is not full as the character length is a issue. Also i cannot attach the file in txt , html, pdf, doc as it has mime issue, Let me know which line you want... i will update those lines from frame.cls.php

Thanks

Hello,
Okay in the mean time, i get the solution for the above, I am thinking of opening the saved PDF directly from the server location.

[eluser]Sbioko[/eluser]
So, are you still need my help?

[eluser]jbreitweiser[/eluser]
Try setting the document type to pdf and just stream the results of your pdfobj directly to the usser. No need to write it to the servers file system.

[eluser]Sbioko[/eluser]
Try to not use the $GLOBALS. You can put this unique id into the session(for example). Your script just does not see the $dompdf_unique_id variable. Make it global using other alternative ways.

[eluser]bhakti.thakkar[/eluser]
Thanks Sbioko,
I replace
$this->set_id($GLOBALS['dompdfuniqueid']++);
WITH
$this->set_id( uniqid(rand()) );

in frame.cls.php and its working wonders!!!

Hope it helps someone

[eluser]Sbioko[/eluser]
Good luck :-)
