Output on Front End

[dskurth]

I have succesfully used this library within the backend (dashboard )of a wordpress enviornment. Now I need to create the same PDF, that a user can click on a button and it either displays the PDF file (like in the backend) or allow it to be downloaded. I have tried all the different parameters of Output() as follows:

ob_clean();
$pdf->Output(); // Does nothing

ob_clean();
$pdf->Output('I', ''); // OPENS IN SAME PAGE

ob_clean();
$pdf->Output('D', 'test.pdf'); // Opens file save and then hangs.
$pdf->Output('D', ''); // Opens file save and then hangs.

ob_clean();
$pdf->Output('F', 'test.pdf'); // Should save file, does nothing

How do I achieve this?
