generated PDF broken by include

[chr15t0]

Hey chaps,

the following code generates a perfect PDF document:

#       require('include/top.php');
        $foo='voon';
        $pdf = PDF_new();
        PDF_open_file($pdf);
        PDF_begin_page($pdf,595,842);
        $font = PDF_findfont($pdf,"Helvetica","host",0);
        PDF_setfont($pdf,$font,38.0);
        PDF_show_xy($pdf,"$foo",50,700);
        PDF_end_page($pdf);
        PDF_close($pdf);
        $buf = PDF_get_buffer($pdf);
        Header("Content-type: application/pdf");
        Header("Content-Length: ".strlen($buf));
        Header("Content-Disposition: inline; filename=pdftest.pdf");
        echo $buf;
        PDF_delete($pdf);

however, if I uncomment the first line require('include..., I get the following popup error in IE: "Acrobat Reader: The file is damaged and could not be repaired"

the required file contains the following:

<?php
        $foo="bar";
?>

Is there something daft I'm overlooking?

thanks
christo

Are you sure that's all that's in there? I.e., no blank lines or anything outside the <?php...?>?

If you were to open the "corrupted PDF" in a text editor or file viewer, I'm guessing you'll see an error message about headers.

thanks for the reply, Weedpacket

as it happens, I fiddled some more and got it working, (with code as below). No - there's nothing else there, no blank lines or anything.

This all stemmed from a more ugly problem which I have been suffering from when using sessions within the same script - yup that's the one.. IE doesn't understand the pdf headers when the cache-control parts of the session headers have already been sent.

Anyway, I'll explore some more and post about that one in a separate thread. Meanwhile, here's the working version of the above problem.

<?php
        /*
                test pdf script to work without sessions
                $Id: pdftest.php,v 1.3 2003/08/26 19:35:50 chris Exp $
        */
        include('include/template_nosess.php');
#       $foo='bar';
        $p = PDF_new();
        PDF_open_file($p);
        PDF_begin_page($p,595,842);
        $font = PDF_findfont($p,"Helvetica-Bold","host",0);
        $now=date ("dS F Y");
        PDF_setfont($p,$font,38.0);
        PDF_show_xy($p,"$foo",50,700);
        PDF_end_page($p);
        PDF_close($p);
        $buf = PDF_get_buffer($p);
        Header("Content-type: application/pdf");
        Header("Content-Length: ".strlen($buf));
        Header("Content-Disposition: inline; filename=pdftest.pdf");
        echo $buf;
        PDF_delete($p);
?>
