I am wondering how to retrieve the actual data of a field instead of the tid on a node. Googling around I found a solution to a similar problem, by constructing a query on my own. However, it is usually the case that a function already exists for this. Do you know how I can achieve this?
What I get is something like this
field_category (Array, 1 element) -> und (Array, 1 element) -> 0 (Array, 1 element) -> tid (String, 2 characters ) 18
