I have a hierarchical taxonomy called 'tarefa'
I have to display all posts from a child taxonomy. I used get_term_children function function to verify if the taxonomy parent has children.
If the taxonomy parent has children I will query posts by taxonomy children.
The problem is:
I have to query posts by taxonomy slug but the function get_term_children return an array of taxonomy IDS.
The question is:
How can I return a taxonomy slug by a taxonomy ID?
