I have also bough the Cookbook, and scoured the forum and the cookbook for an answer for this:
I have a listing of used equipment, each record of which links to a detail page for each item. I also created another detail page which will be converted to PDF so the customer can print off, email etc.
Every time i put the code into the page i get the following issue:
If i put the createPDF code like this:
in the header
<?php if (@$_REQUEST['pdf']) { createPDF_fromOutput('inline', 'example.pdf'); } ?>
in the body
<a href="http://used.haeuslers.com.au/listing/listingInfoSheet.php?pdf=1&<?php echo $listingsRecord['num'] ?>">CLICK TO CONVERT THIS PAGE TO A PDF</a>
which id about halfway down the page, i get an error like this:
createPDF_display: Can't output PDF because headers already sent! Output started in /home/haeusler/public_html/used/listing/listingInfoSheetPrep.php line 125. Make sure you don't have any html or whitespace characters in your code before calls to createPDF_ functions.
If i move it up to the top of the page, it makes a PDF, but it is just a blank white page.
The only errors after i installed and tested it were ones that required me to add the switch to ignore errors.
Running the test in the admin section, the google page works correctly.

Could you attach listingInfoSheet.php to this thread along with a link to a page than demonstrates the problem? That way we'll be able to take a closer look into this
Hope this helps

Thanks for you help mate, it ended up being a DNS problem, of all things!
The domain name it is running on only has entries in our local DNS server, not to the public. I got it to the stage where it would make PDFs of any public website, but all "internal" pages would just come up blank.
Anyway, I made the domain name public and the problem disappeared. Obviousy the PDF engine uses the DNS of the hosting provider to resolve the domain name, which is where i was coming unstuck. [crazy]

I even worked out a way to dynamically name the PDF file with a bit of trial and error.. [;)]
<?php require_once "lib/viewer_functions.php"; ?>
<?php
$filename= $listingsRecord['manufacturer']."-".$listingsRecord['Model'];
$num= $listingsRecord['num'];
$url = "listingInfoSheet.php?".$num;
$data = createPDF_fromUrl($url);
createPDF_display('attachment', $data, $filename.'.pdf');
?>Now the customer's file is meaningfully named, instead of 4 different "example.pdf" files.
Now to play with a few switches and see what else I can do!
