DEFAULT_URL

I need to be able to define DEFAULT_URL via a php script. My script is based on viewer.html, but it gets a filename from a database with an ID, and defines that in the header:

echo "var DEFAULT_URL = '".$file."'";

This doesn’t seem to be working for me in 2.0 - how would I go about defining DEFAULT_URL now? Exposing the location of the pdf file in the URL is simply not an option for me, nor is defining it in the viewer.js file.

As explained in the FAQ there’s another, and possibly even easier, way to achieve this; please see https://github.com/mozilla/pdf.js/wiki/Frequently-Asked-Questions#file

To summarize: Load the viewer with an empty ?file= parameter, as in e.g. https://mozilla.github.io/pdf.js/web/viewer.html?file=, and then call PDFViewerApplication.open(/* file here */) to load the PDF file.

@Snuffleupagus I tried placing this code in the header of viewer.html:

PDFViewerApplication.open('<?=$file;?>');

And I get this error:

Can't find variable: PDFViewerApplication
