get_the_terms return only last term

Question

In my custom post type (portfolio_pt) I have some hierarchical category structure something like that:

ParentCat
|-child
    |-someItem
ParentCat2
|-cild
...

When I try to get list of all terms by get_the_terms function for "someItem" post this function return only last category ("Child Cat" without "Parent Cat") example:

global $post;
$terms = get_the_terms( $post->ID, 'portfolio_pt_category' );

I try to use get_the_term_list function but effect is the same, it returns only last category.

Thanks for help!

Instead of get_the_terms try using get_terms and set the hierarchal argument to true. Also make sure you show empty so you are not hiding your empty categories.

Try something like this:

$args = array(
'hide_empty'    => false,
'hierarchical'    => true
); 
$terms = get_terms('portfolio_pt', $args);

foreach($terms as $term)
    echo $term->name;
