Dynamic files for phpmailer using dompdf

Question

I am generating pdf file using dompdf whose filename keeps changing as I have assigned a variable in dompdf stream output and this filename always remains as unique filename.

I want to attach a file in my mail where I am using phpmailer.

Problem: Able to attach file properly if I assign a particular file name in phpmailer as static file(with particular name assigned), but not getting successful for dynamic files (using variable as below). Here, $attach is my php variable for file name.

Trying out below code:

$dompdf->stream($attach);//Code for dompdf

$mail->AddAttachment('C:\Downloads\$attach.pdf');  //code for phpmailer to attach file

Answer 1

What i did is like this...........

       I got all my html code in the following variable called `$html`.Then i followed below procedure.
$dompdf->load_html($html);    
$dompdf->render();
$pdf = $dompdf->output();
$file_location will have dynamic file name.
file_put_contents($file_location,$pdf);

Now use this $file_location variable for attaching the file name to php mailer. This you need to write in the same php file where you are generating pdf.
