fpdf

Hi, I want to display the results generated by the query and generate a pdf document (using fpdf) for the users to save. The user should be able to save it by clicking on a save button. I have a script called display.php which displays the result of the query..now I want user to be able to save by pressing save button. That is I want to do this in the display.php script itself, because the result of the query is too large to POST to another script. If I do: $pdf->Output("/tmp/new.pdf"); then I can save the pdf document..but I want this to happen only if the user clicks on save button and he/she should be able to download it by doing so. How to do this? Thanks in advance, Mukta
