Anyone know how to save a form filled PDF to the server rather than outputting to the browser in PHP?

I have a script that merges PDFs, saves the file and then gives the browser the option to open or save:

exec("pdftk " . $str . " cat output audit.pdf");

I also have a script that takes form data and merges it to a PDF, *BUT* it only outputs to the browser:

passthru("pdftk form.pdf fill_form " . $fdf_fn . " output - flatten");

What I want is to just save the PDF file on the server after the user submits the form data.

I was thinking to try this:

exec("pdftk form.pdf fill_form " . $fdf_fn . " output application.pdf flatten");

...but this doesn't work. I would think removing the passthru() and "output -" would fix it since those are used if you just want a temp file to load into the browser. Any ideas ?

Thanks.

Hi

exec("pdftk form.pdf fill_form " . $fdf_fn . " output application.pdf flatten");

It doesn't work you say. Do you have any idea why it doesn't work? When you call exec like that, you lose any error message. It could be a permission problem? Does the webserver have permission to write to "application.pdf"? I'd change the exec into a passthru to see if I could read the error message.

thanks. you were right, it was a permission error.
