[FX.php List] [off] Anyone familiar w/ mPDF who could help?

Fri Jan 13 14:04:53 MST 2012

Well, what's odd is that their example works fine, and it's just a long string of HTML then this

include("../mpdf.php");
$mpdf=new mPDF(); 
$mpdf->WriteHTML($html);
$mpdf->Output();
exit;

Mine is basically the same, except that at top I have code that grabs the records for each report and saves the variables for use in the HTML below.

The only difference may be that mine is going into a DIV using jQuery, while their example's a standalone PHP page not inside my jQuery. The more I think about it, the more I think that may be what is causing the difference…

That being the case, would I need to call those header() commands at the top of my mPDF calls, or at least, beore the Output() call?

Disclaimer; It's been a while since I did this, but that's what I recall. The rationale is that with the latter the client doesn't know it's a PDF, hence doesn't know how to open it, and should therefore download the file.
