I found a previous post that was incredibly helpful (http://wordpress.org/support/topic/custom-taxonomies-conditional-tags?replies=13). However, it is now closed. At any rate, I've used Justin's bit of code, and it works really well except in the instance of where I have multiple custom taxonomies. Meaning: I want to check if a post has a term in two different custom taxonomies (For instance: Custom Tax: GradeOne, Custom Tax: GradeTwo, etc. -- I want to be able to check if it is in either custom tax.)
I may just not know php well enough to adjust Justin's Code. I am more than happy to provide additional details if need be.
