  • Resolved Naturalrush


    Eric, thanks again for the plugin but I’m encountering some issues in getting it implemented.

    This was working fine on a WP site using a WAMP setup. I then moved it to a production server WIMP running IIS 6 (stuck with that setup) and the document downloads result in empty files. No errors are being thrown. It appears to download fine except it is a 0kb file with nothing in it.

    I can upload documents/publications just fine.

    I can also go to the built-in WP media library, see the PDF (in this case), click View and the attachment ID link to get it. My guess is it is someting to do with the openfile.php in a Windows environment.

    I’ll see if I can figure something out but wanted to go ahead and put this issue on here.

    Error logging some output values, the path and filename look good.

    The URI passed in on the $fPath var in openfile.php is valid, and logged into the site I can put that URI in the brower address and download the file. Path is valid. PHP can read and write it since it was uploaded in the first place.

    I even tried commenting out the output buffering and using straight cURL with the same results.

    Thanks for pointing this out. Unfortunately, I don’t have an IIS setup I can test it in so I can’t reproduce this locally. If you find anything out, though, please let me know and I’ll see what I can do to patch it.

    This is an unusually quiet Friday night. So, with this gnawing at me I decided to look at it again. Good grief, I don’t know how I missed it. The URL isn’t valid. It is missing a slash so it’s http:/ instead of http://. Argh! Using an HTTP inspector it’s passing it fine. In fact, I was surprised to see it wasn’t properly url encoded. It appears this is an area where not all web servers behave the same. Apache allowed it but IIS 6 botched it without error.

    One possible fix is line 92 of lib/class.publication-markup.php, the $uri var can be wrapped in urlencode(), so
    return $downloadroot . urlencode($uri)
