I have a form button, when clicked it submits the form.
I'd like that at the same time, the browser starts downloading a PDF file. I wonder how can I do this? Please keep in mind that PDF are usually opened by the browser by default, but I'd like the browser to Save As the file and not open the file. Is this do-able using html only or do I need javascript?
If you are using PHP in the server side try this. This is tested code which is running in one of my websites.
<?php
ob_start();
$file = 'YOUR-FILENAME-HERE.pdf';
if (file_exists($file))
{
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
exit();
}
?>
Browser will prompt to download without displaying it in the browser.
