referencing by document id with friendly alias paths enabled

I’m trying to use a snippet that is called with the current document ID as an argument. It isn’t working properly, and I noticed the following. I have friendly alias paths enabled, but I was under the impression that a call for document 36979 like:

index.php?q=36979

ought to work regardless. However, it doesn’t. If I call

index.php?q=journal/fj61/36979

then that works, as does

index.php?q=journal/fj61/article4.html

Am I wrong that the document should be callable directly by the id without the paths? If not, is there an easy fix to the snippet so that it calls the current document even with FURL paths turned on?

In snippet code, $modx->makeUrl(36979);

In HTML (content or template or chunk) [~36979~]

Thanks for the help. Do you know the answer to my first question -- Should the document still be callable directly by the id without the paths even with FURL paths on?

[~id~] will create the path according to the FURL settings. With FURL on the url will be index?id=123 with FURL on the same placeholder will output /path/alias.html

This is the same way that $modx->makeurl(id) works inside a snippet. So rather than outputting the url directly, use the makeurl() function to do it for you and the path will be built accordingly.

In snippet code, $modx->makeUrl(36979);
