Pieforms or. json_repy problem
21 December 2009, 9:37 AM
I get a response from web service. The response is a valid MS Word (or OpenDocument or PDF or XML file). I would like to "pass" this response = file to user, so he/she could save this file to his/her computer. I've done that with following lines:
header('Content-Disposition: attachment; filename=cv.doc');
but then the statement
$form->json_reply(PIEFORM_OK, 'some string');
doesn't get executed (I think?!?). So on the left upper corner it says "Loading..." and the Submit button has a label "Processing..."
What should I do, to make this function to finish or to make these labels to disapear?

I'd try calling the serve_file() function from htdocs/lib/file.php which will set those headers for you, and also make sure your pieform submit function calls $form->reply(PIEFORM_OK, 'some string').
You might also want to look at the code that serves up the export file (htdocs/export/index.php, htdocs/export/download.php). It's probably a bit more elaborate than you need (it displays a progress bar in an iframe) but it will give you an idea.

I looked at mentioned files, but they assume that you first have to create file on server and then serve it - or maybe am I missing sometnihg?
I want to send the data in an XML form to Europass Web service to get Europass CV or Language portfolio as file - then I want to serve that file instantly (I don't want to write it on server's disk). Is it possible with serve_file() function?

Yeah, you're right, it's no good for what you're trying to do, there's a whole lot of stuff in there that assumes it's a file on the filesystem. I don't know of any code that does what you're trying to do exactly. But I suspect it will work okay if you use the same approach as in the export code, by serving up your headers and xml data from a separate script loaded in an iframe.
