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>

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);

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.

So, are you still need my help?

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.

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.

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
