PDF attachment seems to be malformed

    I had a problem with outputting the PDF inline in Chrome (gray blank screen), so I changed this line in wp-mpdf.php:

    Header('Content-disposition: inline; filename='.$pdfname);
    to:
    Header('Content-disposition: attachment; filename='.$pdfname);

    so the browsers behave the same and try to download the PDF as a file/attach.

    But, the resulting PDFs seem to be malformed (bad xref table?). Adobe Reader asks me to (re)save the file when I close. Tested with Adobe Reader X 10.1.9 and Acrobat X Pro 10.1.8

    On closer inspection, it seems to happen only for certain files/posts. I’ll check the debug files to see if I can find the cause.

    Okay, it appears to only happen when I include links to files in the HTML that outputs to the PDF. When I remove the file links, the PDF is fine.

    How do you add file links? Do you have a plugin which may includes the file into the site itself?

    They are added using shortcodes inserted via Types (part of Toolset). The file fields are custom fields defined in Types. So, a user uploads the files below the post editor area and then inserts the codes to display them.

    I think the way Types inserts is likely the issue because links added manually don’t break the PDF. For now, I’m hiding the Types-inserted links via the wp-mpdf theme’s default.css until I can determine why they are breaking PDF output.

    (also, I figured out the other issue with wp-mpdf that I had before and neglected to follow-up on)

    Great plugin!

    So if you hide the output of your custom blog with the PDF template css file it works? That kinda sounds like the output for the custom block is just messed up. I guess there is nothing I can do to fix that.

    Yes, I think it has less to do with your plugin and more to do with mPDF’s generation. There are other shortcodes (though not all) that output valid XHTML yet somehow corrupt generated PDFs. It works better if I use the WP editor only. I had planned to use it to generate the documents for dynamic content via cron, but will have to do more research on mPDF generation.
