Make sure that you are NOT sending any data to the user before executing TCPDF. That means that your PHP block is at the very beginning of your file. There can't be even an blank lines before it.
@@jayeshkarale9118 Please post the code that you've tried. Your output path is probably incorrect - how did you specify it? Try using absolute path or _ _ DIR _ _ . "/folder/name.pdf" to save to a folder that's in the same directory as the file containing the code. Also check the output folder permissions.

hello i have this problem when i click button Create PDF (TCPDF ERROR: Some data has already been output, can't send PDF file) Please Help me. plz heelllpppppppppppppppp
Just use ob_start(); at the top of the page and the function ob_end_clean() before call the Output function: ob_end_clean(); $pdf->Output($pdf_name, 'I'); It solved my problem. Nice tutorial thanks.
This would be ten times more effective if you narrated it with your own voice instead of the computer-generated robotic voice. It's very distracting and makes the whole thing difficult to follow.
While the voice is horrendously annoying, it was indeed quite informational. And, at the risk of sounding racist, I'd rather hear a generated voice than someone speaking something barely passable as English. The video was great! It helped me a lot at my new work practicum.
Object PDF Object ... Nice Tutorial Thanks.

How to save pdf file in folder
Good day i am having a problem Fatal error: Uncaught Error: Class 'TCPDF' not found
it's probably because you have not downloaded the tcpdf libbrary, get it at sourceforge.net/projects/tcpdf/

Same thoughts! It's really distracting.
