Hi... I'm new in chronoengine... I'm looking for a form application that can print on pdf file the form just compiled.
I'm trying chronoform and it seems very very good but when I've problems with pdf. I've installed the action tcpdf, downloaded from here, I've added as event in the setup, on submit and tryed with a simple form... compiled form, on submit it gives this message:
TCPDF ERROR: Some data has already been output to browser, can't send PDF file
someone can helps me???

here is the sample

Hi Liotine,

What actions do you have in the "on submit" event ?

What's the url in the browser's address bar when you get the error ?

Regards,
Max

HI Liotine,

I'm sorry, I don't know how this action works on WordPress :-( Do you have the same problem if you save the PDF to the server instead of using Immediate download?

Hi Bob, I've tryed other plugins that generate pdf from html and they works.... If I save to server I have a strange situation:

Fatal error: Call to undefined function GCore\Admin\Extensions\Chronoforms\Actions\Tcpdf\jimport() in /home/mhd-01/www.gianniliotine.it/htdocs/aerospazio/wp-content/plugins/chronoforms/admin/chronoforms/actions/tcpdf/tcpdf.php on line 138

Hi Max, you can find the form here: http://www.gianniliotine.it/aerospazio/
Here you can find some screenshot images of the pages...
after submit the url is www.gianniliotine.it/aerospazio/?chronoform=myForm&event=submit

Hi Liotine,

Good catch, could you please send me a message using the "Contact us" page to get a patch to try ?

Regards,
Max
