I am trying to get the term children and then check if they exist to display them. But I get no IDs in return of get_term_children command. This is the code:
$children = get_term_children($term->term_id, locations);
echo $children;
$term is already defined and outputs well, “locations” taxonomy exists. The code returns me just an “Array” word, no list of child terms shows up.
I’ve got a similar code in my post archive pages and it works well returning me child categories in n/n/n/n/n format:
$children = get_category_children($this_category->cat_ID);
echo $children;
What’s wrong with the first code? It should work as well as the second.
At first, try passing the Taxonomy as a string:
The function get_category_children produces a string as return, so you can just echo it.
the function get_term_children, however, returns an array. To see the contents of the array, try
instead of echo.
The last thing to keep in mind is that a taxonomy does not need to be hierarchical – for example the built in tags. Be sure your “locations” is organized hierarchical, otherwise get_term_children won’t work for you in this case.
