Question

I am currently using wkhtmltopdf to generate pdf files and I would like to link the recently generated files for the user to download but after the user is finished with their session to delete them. Is there anyway to accomplish this without even having the file generated on the server?

Answer 1

<?php
exec("/path/to/binary/wkhtmltopdf   http://www.google.com /location/test.pdf");
$file = "/location/test.pdf";
$pdf = file_get_contents($file);

header('Content-Type: application/pdf');
header('Cache-Control: public, must-revalidate, max-age=0'); // HTTP/1.1
header('Pragma: public');
header('Expires: Sat, 26 Jul 1997 05:00:00 GMT'); // Date in the past
header('Last-Modified: '.gmdate('D, d M Y H:i:s').' GMT');
header('Content-Length: '.strlen($pdf));
header('Content-Disposition: inline; filename="'.basename($file).'";');
ob_clean(); 
flush(); 
echo $pdf;

unlink($file);

?>

there could be an issues with files not beeing deleted so, i would add a cron job for deleting old ones.
