genesis();

Assumptions:

• post type is 'my_cpt'
• taxonomy is 'cpt_category'
• taxonomy term is stored in 'be_category_listing' post meta
• you want to use the standard genesis loop for it

Possible Changes:

• You might want to do some validation of the post meta field to ensure the term exists before querying for it
• You might want to build your own query instead of letting Genesis do it. In that case, replace genesis_custom_loop() with $loop = new WP_Query( $args ) and do the loop yourself. More info: http://www.billerickson.net/custom-wordpress-queries/

Wow, thanks for the great response Bill! Below is the template I'm working with. I added the 'meta_value' line in the beginning to "hard code" the value into copies of the original portfolio-template.php, but this isn't very flexible.

It appears that lines 25-26 are most relavent. I'll try adding that in, but thought seeing the actual template I'm working on might be helpful

Question, outside of good coding practice, what would be the benefit of the post meta field validation?

Sorry if I didn't mention this isn't a Genesis flavored theme, it's my first time venturing out of the Genesis community! And I don't know if I'll do that again.
