Hello -

Does anyone know how to modify the Wordpress canonical links to add a custom URL parameter?

I have a Wordpress site with a page that queries a separate (non-Wordpress) database. I passed the URL parameter "pubID" to display individual books and it is working OK.

Example: http://www.uglyducklingpresse.org/catalog/browse/item/?pubID=63

But the individual books are not showing up properly in Google - the ?pubID parameter is stripped out.

I think maybe this is because all the item pages have the same auto-generated "canonical" URL link tag in the source - one with the "pubID" parameter stripped out.

Example: link rel='canonical' href='http://www.uglyducklingpresse.org/catalog/browse/item/'

Is there a way to perhaps edit .htaccess to add a custom URL parameter to Wordpress, so that the parameter is not stripped out by permalinks and the "canonical" links?

Or maybe there's another solution ... Thank you for any ideas!
