I am using moodle 2.2 and i want to fetch some useful information of user on certificate
when i wrote this code to fetch
certificate_print_text($pdf, $x+120, $y+30, 'C', 'Helvetica', '', 14, $questionnaire->view_response($rid));
it give error
TCPDF ERROR: Some data has already been output, can't send PDF file
and certificate saved without fetching that information
I had wrote my own code there for fetching data.
Hi Sam,
Some information is being output to the browser window before the pdf is sent to the browser to be downloaded. I suspect you have an echo statement or the equivalent in your certificate type folder, or the view.php file.
More code would be helpful.

Mark
hey
thnx mark,,
you rock
Hi Sam, How resolve your problem
Hi Mark,
I am having the same problem on a M2.5.
The certificate was working fine when I was last adding content, but today I'm getting the TDPDF Error: some data has already been output.
Have you any suggestions as to why this error should occur on a site that has had no code changes.
Moodle version 2.5.4+, Firefox & Chrome browsers on Windows and Android.
Thanks,
Mairsile Hourihane
