how to associate language with filename+extension

[Jean-Luc Picard]

I am trying to get N++ to recognize files with this pattern as javascript files:

_js.php

so the file could be something like:

global_includes_js.php

or

my_awesome_stuff_js.php

I found this thread: http://superuser.com/questions/413524/how-do-i-get-notepad-to-associate-a-file-type-with-a-language

and tried it but it didn’t work. I tried both restarting N++ and reopening the files.

Is it possible to match the end of the filename and the extension, or can it only match the extension?

Use something like

example1.js-php

or

example2.js_php

and associate that extension (i.e. exclud leading dot) with JavaScript using the instructions of the aforementioned superuser.com thread.
